INTRODUCTION INTRODUCTION TO TO CONSCIOUSNESSCONSCIOUSNESS
Study of consciousnessStudy of consciousnessThrough combining and sharing
the perspective of different disciplines: philosophy, psychology, medicine and neuroscience (Bock and Marsh, 1993)
Definition of Definition of consciousnessconsciousnessFor the purpose of descriptive
clinical psychopathology, consciousness can be simply defined as
-- a state of awareness of the self and the environment (Fish, 1967)
Consciousness is to be consciousness to know about oneself and the world. It is better used as an adjective than noun– a man does not posses consciousness--- -- the object of consciousness is its essential social dimension ( Sharfetter,1980)
preconsciouspreconsciousAmong unconscious, for which
there is a good evidence of their existence, frequency, and complexity, there are some which have been, or may yet become, conscious. This is what Freud called Preconscious (Frith, 1979)
conscious Vs conscious Vs preconsciouspreconscious Strict limit to the no of
items available
If stimulus is, only one interpretation is possible at one time
Very difficult to carry out more than one task
Flexible, strategic Conscious is executive in
nature and is dominant to and has the capacity to override the perceptions and functions of preconscious process
Very much more information is stored
Multiple meanings are available
Undertaking parallel task is usual
automatic
unconsciousunconsciousJasper(1957)- meaning of
unconsciousness --it is not an inner existence, does not occur as experience
--not thought as an object and has gone unregarded
--something which has not reached any knowledge of self
Clinicians use of Clinicians use of consciousness and consciousness and unconsciousnessunconsciousnessinner awareness
of experience
the subject reacting to objects intentionally
denotes a knowledge of conscious self
There is no subjective experience
Seen as conscious– unconscious continuum
Three dimensions of Three dimensions of consciousness and consciousness and unconsciousnessunconsciousness Vigilance(wakefulness)----
-drowsiness(sleep) axis
Lucidity ----clouding axis
Consciousness of self
Normal state of consciousness----- death(in a person suffering from serious brain disease)
Full wakefulness-----to deep sleep( in a person who is sleep)
Full vigilance ------total unawareness(in an alert and healthy person
The organic state of brain, as for instance, demonstrated by EEG, is utterly different in these three situations
Vigilence(wakefulness)---Vigilence(wakefulness)---drowsiness(sleep) axisdrowsiness(sleep) axisThe faculty of deliberately remaining
alert when otherwise one might be drowsy or sleep.It fluctuates
Factors influencing vigilance– interest, anxiety, extreme fear
or enjoyment (promotes vigilance)-- boredom( promotes
drowsiness) --the situation in the environment and the way the individual perceives the situation
Qualitative difference in the nature of wakefulness
--- the significant state of mind of a person scanning radar screen for possible enemy interceptor is very different from the rapt attention of music lover listening to a symphony
Lucidity--- clouding axisLucidity--- clouding axisConsciousness is inseparable
from the object of conscious attention: lucidity can only be demonstrated in clarity of thought on a particular topic
Lucidity Vs vigilance– unless the person is fully awake he cannot be clear in consciousness
Clouding denotes the lesser stages of a impairment on a continuum from full alertness and awareness to coma(Lishman,1997)
The pt may be drowsy or agitated, and is likely to show memory disturbance and disorientation
Most intellectual functions are impaired including attention, and concentration, comprehension and recognition, understanding, forming associations, logical judgment, communication by speech and purposeful action
Consciousness of selfConsciousness of selfAbility to experience self and
awareness of self that is both immediate and complex
DISORDERS OF DISORDERS OF CONSCIOUSNESS—CONSCIOUSNESS—PSYCHOPATHOLOGICAL PSYCHOPATHOLOGICAL ASPECTSASPECTS
Classification of disorders of Classification of disorders of consciousness (Fish)consciousness (Fish)Consciousness can be changed in
three basic ways it may be dream like,depressed, or restricted
Classification of Disorders Classification of Disorders of consciousness(Sims)of consciousness(Sims)
Quantitative lowering of consciousness
Qualitative change of consciousness
Normal(alert, vigilant, lucid)
Clouding DrowsinessSoporComa Death
DeliriumFluctuationsConfusion
Disorders of consciousnes Vs Disorders of consciousnes Vs dementiadementiaDisorders of consciousness are associated
with disorders of perception, attention, attitudes, thinking, registration and orientation
The pt with disturbance of consciousness usually shows, therefore, a discrepancy between their grasp of the environment and their social situation, personal appearance and occupation.
This lack of comprehension in the absence
of other florid symptoms of disordered consciousness may lead to a mistaken diagnosis of dementia
Disorders of consciousness Vs Disorders of consciousness Vs orientationorientationWhen consciousness disturbed it
tends to affect three aspects– time, place, and person in that order
If patient is disoriented for time and place, it is customary to say that they are confused
Most patients with confusion are
perplexed, but this sign is also seen in sever anxiety and acute schizophrenia in the absence of disorientation
QUANTITATIVE QUANTITATIVE heightening of heightening of consciousnessconsciousnessThere is a subjective sense of richer
perception: colours seem brighter, and so on.
There are changes in mood, usually exhilaration perhaps amounting to ecstasy
There is subjective experience of increased alertness and a greater capacity for intellectual activity, memory and understanding
May be associated with synaesthesia- a sensory stimulus in one modality resulting in sensory experience in another
--eg; hearing a finger nail drawn down a blackboard results in a cold feeling down the spine
Conditions seen are -- normal healthy people– esp
in adolescence or at times of emotional, social or religious crisis, when falling in love, on winning a large sum of money, at sudden religious conversion and so on
--drugs– notably with hallucinogens(LSD), CNS stimulant(amphetamine)
--occasionally in early psychotic illness, esp mania, or less often in schizophrenia
QUANTITATIVE QUANTITATIVE lowering of lowering of consciousness consciousness Impairment of consciousness is the primary
change in acute organic reactions and holds a fundamentally important place in the detection of acute disturbance of brain function and in assessment of severity(Lishman,1997)
Some conditions may produce a variable level of diminution of consciousness: that occurring with migraine: for example, may range from blunted awareness through lethargy and drowsiness to loss of consciousness(Lishman,1997)
clouding clouding
Lesser stage of consciousness associated with deterioration in thinking, attention, perception, and memory and usually drowsiness and reduced awareness of environment
although pts awareness is clouded, he may be agitated and excitable rather drowsy
The term clouding should be used for the
psychopathological statea)impairment of consciousness
b)slight drowsiness with or without c)and difficulty with attention and concentration
This will usually occur with organic impairment of function
Clouding Vs sleeping--There are important differences between the reduced wakefulness before falling sleep and clouding in an organic state (Liowski, 1967)
drowsinessdrowsinessNext level to clouding of consciousness
As a descriptive term simply means diminished alertness and attention which is not clear under the patients control
Pt is awake but will drift into sleep if left without sensory stimulation
Associated with--slow in action--slurred speech
--sluggish in intention--and sleepy on subjective
description
There is an attempt at avoidance at avoidance of painful stimuli; reflexes, including coughing and swallowing are present but reduced muscle tone is also diminished
These level of diminished consciousness are quite non-specific and occur whatever the nature of the cause
Conditions seen-- in the psychiatric practice this is commonly seen following
over dosage with drugs that have a central nervous depressant
effect. In such case interviewing the pt is impossible
comacomaPt is unconscious. In slight state, with
strong stimuli he may be momentarily arousable. In later stages pt is no longer arousable, he is deeply unconscious
There are no verbal responses or responses to painful stimuli
The righting response of posture has been lost. Reflexes and muscle tone are present but greatly reduced
Breathing is slow, deep and rhythmic. The face and skin may be flushed
Distinct stages of coma have identifiable physical signs ultimately culminating in brain death, (conference of medical royal college,1976)
Practical assessment of the depth and duration of impaired consciousness and coma has been quantified in the scale devised by Teasdale and Jennett(1974)
QUALITATIVE changes of QUALITATIVE changes of consciousnessconsciousness Definition of delirium Definition of delirium
Lishman– a syndrome of impairment of consciousness along with intrusive abnormalities of perception and affect
DSM-IV– in a global sense to describe a disturbance of consciousness that is accompanied by a change in cognition that cannot be better accounted for by a pre-existing or evolving dementia. There is a reduction in the clarity of awareness of environment(DSM III term– acute brain syndrome, dementia is its chronic form)
ICD-10 (P. 54) an etiologically nonspecific syndrome characterised by concurrent disturbance of consciousness and attention, perception, thinking, memory, psychomotor behaviour, emotion and the sleep-wake cycle
Symptoms of deliriumSymptoms of deliriumThere is some lowering of consciousness,
which is subjective experience of a rise in the threshold for all incoming stimuli
The pt is disoriented for time and place but not for person.
Thinking is disordered as it is in dreams and shows excessive displacement, condensation and misuse of symbols.
The pt is unable to distinguish between their mental images and perceptions, so that their mental images acquire the value of perceptions
Hallucinations in delirium Hallucinations in delirium Visual hallucinations– --often the outstanding
feature --usually of small animals and associated with fear or even terror
Elementary auditory hallucinations are common.
Rarely hallucinatory voices occur if they do– the change of consciouness and visual hallucinations often disappear in a few days, leaving behind an organic hallucinosis with little or no change in consciousness
Other hallucinations of touch, pain, electric feelings, muscle sense and vestibular sensations often occur
They may be associated with Lilliputian hallucinations (seeing little men), so that the pt describes little creatures walking over him--He feels their footsteps and hears them shouting obscene jokes(associated with feeling of pleasure) and abusive remarks in his ear
The patient is fearful and often misinterpretes the behaviour of others as threats. ----Thus a patient with delirium tremens said ‘Don’t hit me; please don’t hit me’ whenever anyone approached, although he had never been subjected to assault
Pt is highly suggestible to spoken comments and perceptual clues, but there is loss of grasp: misidentification and misinterpretation occur
Conditions of deliriumConditions of delirium One tests the patients orientation and if they are
disoriented there is prima facie case they have and organic disorder. (Exception to this may include the patient with chronic schizophrenia)
If this is of recent origin, then it is an acute organic state with disturbance of consciousness.
Although disorientation in an acute illness is strongly suggestive of disordered consciousness, the absence of this sign does not rule out an acute organic state with mild disorder of consciousness
Poor performance on intellectual and memory tasks, inability to estimate the passage of time, and changes in EEG may all suggest an acute organic state
Delirium Vs schiziophreniaDelirium Vs schiziophreniaIt is important to note that the patients
with schizophrenia, regardless of their history of institutionalisation, may also demonstrate significant disturbance of memory(McKenna et al,1990), including impairment of working and semantic memory(Kuperberg& Heckers,2000)
These impairments may also have a significant impact on social functioning
Mild degree of delirium/? Mild degree of delirium/? Toxic confusional stateToxic confusional stateGeneral lowering of consciousness during
the day and be incoherent and confused
At night delirium occurs with visual hallucinations and restlessness, but it improves in the morning(diurnal varation}
Pt may have inconsistent orientation, orientation may vary during 24 hours of the day
There may also be some restriction so that the mind is dominated by a few ideas, attitudes and hallucinations
The pt is usually restless and may carry out the customary actions of this trade; this is known as occupational delirium eg: an accountant may make out a long series of accounts or a bus conductor may ask other patients for their bus fares
This milder varieties of delirium may pass over into an amnestic state, torpor, severe delirium or a twilight state
fluctuations fluctuations Occurs in health, in
sleep and in fatigue.
In epileptics there is fluctuation in relation to fits
In delirious states there may be considerable diurnal fluctuation of consciousness
Also seen with drugs-- mescaline
confusionconfusionRefer to subjective symptoms and
objective signs indicating loss of capacity for clear and coherent thought
It is purely descriptive(of pt’s experience or doctors observation) term does not apply to clouding of consciousness
The term acute confusional state is often used as a synonym for acute organic psyho syndrome( or delirium in DSM IV and ICD 10) in medical literature. Here it refers to a more comprehensive syndrome with chaotic thinking and cognitive failure that includes delirium as sub category (Berrios, 1981)
It is seen in both organic(acute and chronic), and non-organic disturbance(associated with powerful emotions in neurotic disorders)
Confusion may be a prominent symptom in the acute toxic psychosis resulting from the use of high-potency cannabis(Ghodse,1986). It is then, of sudden onset and usually associated with delusions, hallucinations and emotional lability
Other states- Other states- RESTRICTION of RESTRICTION of consciousness- consciousness- Awareness is narrowed
down to a few ideas and attitudes that dominate
the patient’s mind
There is some lowering of level of consciousness
Disorientation in time and place occur
Twilight stateTwilight state
A well defined interruption of the continuity of consciousness (Sims et al,2000)
Restriction of the morbidly changed behaviourAnd relatively well oriented behaviour
It is characterised by a) abrupt onset and end; b)variable duration from a few hours to several weeks; and c)the occurrence of unexpected violent acts or emotional outbursts during otherwise normal, quiet behaviour (Lishman,1997)
ICD_10 includes twilight states under the heading of dissociative(conversion) disorder and when, criteria for organic etiology are met organic mental disorders
Consciousness may be markedly impaired or relatively normal between episodes
There may be associated dreamlike states, delusions, or hallucinations.
Ganser state is, in practice, a sort of twilight state, in which the organic element is often doubious
Different types described are—simple, hallucinatory, perplexed, excited, expansive, psychomotor and oriented twilight states
It is usually an organic condition and occurs in the context of
-- epilepsy, --alcoholism(mania a
potu), -- brain trauma -- and general paresis;
it may also occur with dissociative states.
The commonest twilight state is the result of epilepsy
Hysterical twilight stateHysterical twilight state Restriction of consciousness resulting from
unconscious motives
In some cases the subject sees to be deliberately running away from his troubles. It may be difficult to how much motivation of hysterical twilight is unconsciuos
In severe anxiety the patient may be so preoccupied by their conflicts that they are not fully aware of their environment and find that they have only a hazy idea of what has happened in the past hour or so
This may suggest to the patient that amnesia is a solution for their problems, so that they forget their personal identity and whole of their past a temporary solution for their difficulties
Dissociative fugueDissociative fugue Fugue– wandering state with some loss of
memory. May be of variable duration Conscious simulation of fugue may be difficult to
differentiate from dissociative fugue
Hysterical fugue may be more common in subjects who have previously had a head injury with concussion, possibly because they are familiar with the pattern of amnesia from their past experience of concussion and can therefore present it as a hysterical symptom
Depression Vs fugue--Not all fugues are hysterical-- Depression pts may start to kill themselves and wander about indecisively for some days before finding their home or being stopped by police
Mania a potu(pathological Mania a potu(pathological intoxication)intoxication)This is one type of twilight,
specially associated with alcoholism
It is important to distinguish this syndrome of acute pathological intoxication with alcohol from delirium tremens, which is a symptom of withdrawl.
Four components of pathological intoxication(Coid,1979)
a)the condition follows the consumption of a variable quantity of alcohol
b)senseless, violent behaviour then ensuesc)there is then prolonged sleep d)total or partial amnesia for disturbed behaviour occurs
Pathological reaction to alcohol is preferred term. The reaction is thought to be associated with exhaustion, great strain or hypoglycemia, and to occur esp in poorly defended against their own violent impulses (Keller,1997)
automatismautomatism Phenomenologically, it is action without any knowledge
acting.
It is a defense because mind does not go with what is being done(Kilmur,1963). Behaviour during automatism is usually purposeful and often appropriate
Violence is rare during automatism. When occur it fulfils the criteria for the definition of twilight state
Awareness of environment is impaired. Pt has no memory later what is done
Epileptic automatism---occur during,or immediately after, a seizure and during which individual retains control of posture and muscle tone and perform simple or complex movements
Dream-like(oneroid) stateDream-like(oneroid) stateAn unsatisfactory term not
clearly differentiated from delirium
The pt may appear to be living a dream world and so called occupational delirium
could be mentioned
It is important to look for other symptoms or organic states to make the important distinction between physical illness and a dissociative organic condition
stuporstupor names a symptom complex whose central feature is a
reduction in, or absence of, relational functions: that is, action and speech(Berrios, 1996)
The inability to initiate speech or action(mutism and akinesis) in a patient who appear awake and even alert
Usually occur with some degree of clouding of consciousness. The pt may look ahead or his eyes may wander, but he appear to take nothing in
Characteristic of lesions in the area of diencephalon and upper brain stem, and also frontal lobe and basal ganglia,
It is important to realise , however, that the syndrome of akinesis and mutism in a conscious patient also occur with schizophrenia, affective psychosis( bothe depressive and manic) and in dissociative states
Organic Vs functional stuporOrganic Vs functional stupor
The difference between psychogenic(so called functional) and neurological(organic)
--presence of clear consciousness in former
It is not possible at the time of observation to know whether consciousness clear or not; and even for functional stupor subsequent amnesia is common
After excluding consciousnes, diagnosis of stupor must then be followed by investigation of the differential diagnosis which include both organic and non-organic conditions
Locked-in syndromeA rare but specific condition
Involving the motor pathways in the ventral pons
There is full alertness and feeling but aphonia and total muscle paralysis apart from blinking, and jaw and eye movements(Plum and Posner,1972)
torportorpor The pt is psychologically benumbed
Without hallucinations, illusions, delusions, and restlessness
Pt is apathetic, generally slowed down, unable to express themselves clearly, and may perseverate.( may be mistakenly diagnosed as severe dementia)
Seen in severe infection such a typhoid and typhus, arteriosclerotic cerebral disease following a cerebrovascular accident
After some weeks there is a remarkably partial recovery and the patient is left with a mild organic deficit
INTRODUCTION TO INTRODUCTION TO ATTENTIONATTENTION
attentionattention The ability to focus on a particular sensory stimulus to
the exclusion of others
It can be--active----when the subject focuses their attention on some internal or external event--passive--- when the same events attract the subject’s attention without any conscious effort on their part
Active and passive attention are reciprocally related to each other, since the more the subject focuses their attention the greater must be the stimulus that will distract them( i.e. bring passive attention into action)
Attention is affected by an individuals mind set
Generally non rigid, and is altered in response to incoming information
Disturbance of Disturbance of active active attention--attention--distractabilitydistractabilitycan occurs in
--fatigue,-- anxiety,
(by anxious pre occupation)-- severe depression,
-- mania,-- schizophrenia
and organic states(may be result of a paranoid frame of mind)
schizophrenia and disturbance of active attention--In acute schizophrenia– as the result of formal thought disorder because the pt is unable to keep the marginal thoughts(which are connected with external objects by displacement, condensation and symbolism) out of their thinking, so that irrelevant external objects are incorporated into their thinking
Amnestic syndrome and attention--Pt’s thinking and observation are dominated by rigid sets, so that perception and comprehension are affected by selective attention
INTRODUCTION TO INTRODUCTION TO SELF AND SELF AND EXPERIENCE OF SELFEXPERIENCE OF SELF
Ego and selfEgo and selfFreud (1933) described ego as
standing for reason and good sense while id stands for the untamed passions
The ego has been modified by the proximity of the external world with its threat of danger. The poor ego has the masters and does what it can to bring their claims and demands into harmony with with one another------. Its three tyrannical masters are the external world, the super ego and the id(Freud,1933)
Self concept and body Self concept and body image image The body is unique in that it is experienced both
inside and outside; in both self and object. It is through our body that we have contact with the world outside our self: movement of the body relate us to external space
Self concept refers to the fully consciousness and abstract awareness of self.
Body image is more concerned with unconsciousness and physical matters: it includes experiential aspects of body awareness of self
Sometimes self concept is the same as body concept and at other times, conscious self is conceptualised as being independent of its cage: the body
The body schema and The body schema and cathexiscathexisThe body schema implies a spatial
element and is more than and usually bigger than the body itself. Eg; the body along with clothes, spectacles, instruments, car(while driving)
Cathexis implies the notion of power, force, libido– perhaps analogous to electrical change, the self that makes things happen
According to shield(1935) body images are never isolated, they are always encircled by the body images of others
At any one time the individual only perceives a small sample from a gallery of possible self images
It is the nature of the self and ego to be experienced as either subject of object
The central core of self image consists for a person his name, his body feelings, body images , sex and age
Experience of selfExperience of selfAlthough there is substantial
German literature on Ichbewusstsein or ego consciousness, both of these terms have now been replaced by the term ‘self-experience’
Disturbance is self experience has two aspects --awareness of existence and activity of the self --awareness of being separate from the environment
Four aspects of self-Four aspects of self-awareness(Jasper,1997) awareness(Jasper,1997)
the existence and ACTIVITY of the self
being a unity(SINGLENESS) at any given point of time
Continuity of IDENTITY over a period of time
being separate from the environment ( awareness of ego BOUNDARIES/DEFINITION)
Fifth dimension of ego vitality(Scharfetter,1981,1995) Previously this characteristic was incorporated within the awareness of activity, Which subsumed ‘being’ and existing with other principles
Awareness of Awareness of BEING OR BEING OR EXISTING, EGO VITALITYEXISTING, EGO VITALITY
“ I know that I exist” and this is fundamental to
awareness of self
Awareness of Awareness of ACTIVITYACTIVITY I do something and that I know that I
am doing itEverything I do, in everything I
experience, though every event that impinges upon me, I am aware that the experience has the unique quality of being mine.
“I pinched myself to make sure it was really happening to me” express the relationship we experience between reality and acitiviy
Awareness of Awareness of UNITY/SINGLENESSUNITY/SINGLENESSAt any given moment I know that
I am one personIn health, a person is integrated
in his thinking and behaviour, so that he does not have to be aware of feeling of unity
Awareness of Awareness of IDENTITY/CONTINUITYIDENTITY/CONTINUITY
I am who I was last week, or 30 years ago: I am who I will be next week, or in 10 years time
A feeling of continuity for oneself and one’s role is a fundamental assumptions of life without which competent behaviour cannot take place
Awareness of Awareness of BOUNDARIES BOUNDARIES OF SELFOF SELFI can distinguish what is myself
from the outside world, and all that is not the self
Awareness of Awareness of THE BODYTHE BODYThe ego is firstly the body ego
(Freud, 1933)The body schema the picture of our
body which we form in our mind, that is to say, the way in which the body appears to ourselves
not have abnormal body sensationsIn transsexual there is conflict
between ego and body image
DISORDERS OF DISORDERS OF EXPERIENCE OF SELF –EXPERIENCE OF SELF –ABNORMAL INNER EXPERIENCE OF I-NESS AND MY-ABNORMAL INNER EXPERIENCE OF I-NESS AND MY-
NESSNESS
Clinical range of Clinical range of disordered selfdisordered self In certain normal life experiences
in association with exhaustion, hunger, thirst, ecstasy, acute but appropriate anxiety, sexual arousal, hypnogogic states
In normal people in abnormal effects of pressure or gravity, in sensory deprivation and during hypnosis
Normal people taking drugsa) mild depersonalisation is very common with drugs Eg; tricyclic antidepressents
b) more marked change occur with cannabis, mescalin, LSD (Lysergic acid diethylamide)
In almost all neurotic conditions and related disorders complaints about self-awareness occur
In acute anxiety state, hypochondriacal disorder, dissociation with conversion symptoms, and anorexia nervosa, disturbance of self image is prominent
In psychosis, the self is self disturbed as a part of loss of reality judgment
The neurotic person, irrespective of type of neurosis, is very concerned with himself and how others see him
Disturbance of Disturbance of awarenessawareness of BEING OR of BEING OR EXISTINGEXISTING
All event that can be brought into consciousness are associated with a sense of personal possession, although this is not usually in the forefront of consciousness. This ‘I’ quality has been called personalisation (Jasper,1997) and may be disturbed in psychological disorders
There are two aspects to the sense of self activity -- the sense of existence
--the awareness of the performance of one’s action
Definition of Definition of depersonalisationdepersonalisation
A change in the awareness of one’s own activity occur when the pt feels that they are no longer their natured self and this is known as depersonalisation
Associated with a feeling of unnreality so that environment is experienced as flat, dull and unreal (derealisation)
Depersonalisation is the term used to designate a peculiar change in awareness of self, in which individual feels as if he is unreal (Sedman, 1972)
A subjective state of unreality in which there is a feeling of estrangement, either from a sense of self or from the external environment( Fewtrell, 1986)
Positive features of Positive features of Depersonalisation (Acner, 1954)Depersonalisation (Acner, 1954) Is always subjective, it is a disorder of
experience
The experience is that of an internal or external change, characterised by a feeling of strangeness, or unreality
The experience is unpleasant
Any mental functions may be the subject of change, but affect is invariably involved
Insight is preserved
Excluded from depersonalisation Excluded from depersonalisation (Acner, 1954)(Acner, 1954)The experience of unreality of
self, when there is delusional elaboration
The ego boundary disorder of schizophrenia
The loss of attenuation of
personal identity
Depersonalisation Vs delusionDepersonalisation Vs delusion
Depersonalisation (as if feeling) is not a delusion(experience of unreality that occur in psychosis)
It should be distinguished from nihilistic delusions
– mood congruent delusions occurring in the setting of severe depression -- in which pt denies that they exist or they are alive or that the world or other people exist

Features most prevalent for Features most prevalent for diagnosis Seirra and Berrios(2001)diagnosis Seirra and Berrios(2001)
◦FOllowing four features are most prevalent for diagnosis
--emotional numbing --changes in visual perception
--changes in the experience of the body --loss of feeling of the agency
◦These are features of the disorder that are additional to the the symptom itself
Depersonalisation Vs dizzinessDepersonalisation Vs dizziness
The dizziness and depersonalisation are same experience described differently
Bipolar hypothesis– that two experiences form opposite ends of a dimension describing disturbed self/outside world relationships
Clinical features of Clinical features of depersonalisationdepersonalisationIt has been considered that after
depression, anxiety depersonalisation is the most frequent symptom to occur in psychiatry(Stewart, 1964)
When the pt first experiences the symptoms they are likely to find it very frightening and often think it is a sign that they are going mad. In the course of time they may become more or less accustomed to it.
Many pt who complain of depersonalisation also state that their capacity to feeling diminished
It frequently occurs in attacks which may be of any duration from seconds to months
Typically, in depersonalisation disorder , the altered state lasts for a few hours, in temporal lobe epilepsy for a few minutes and in anxiety disorder for a few seconds
Onset may be insidious and and with no known cause, or it may be in response to provocation
Conditions of depersonalisationConditions of depersonalisation
Organic brain disease– esp temporal lobe disorders (Matthew et al, 1993)
Substance misuse- cannabis, LSD, mescalin, marijuana
Depressive illness--Very occasionally, depersonalisation may be the outstanding feature in a patient with depressive state(DD-schizphrenia- examinar may be mislead by the bizarre description of the symptom)
Anxiety with agoraphobic symptoms, panic disorder, PTSD
Hysterical dissociation– depersonalisation as a symptom , is more frequently associated with depression and anxiety than dissociation
May also occur from time to time in individuals without mental illness, esp when severely tired
and with sensory deprivation Milder degree of dissociative depersonalisation occur
in moderately stressful situation, so that depersonalisation is quite common experience and is reported to occur in at least once in 30– 70 % of young individuals(Freeman, 1996)
True depersonalisation symptoms do occur in
schizophrenic patients, especially in the early stages of illness alongside definite schizophrenic psychopathology
It is also described as a side-effect with prescribed psychotropic drugs, such as tryiyclic anti depressants but because of the common association between depersonalisation and depression, it is difficult always to attribute cause
Depersonalisation symptom Vs Depersonalisation symptom Vs disorderdisorderIt is important to emphasize the
distinction between depersonalization as a symptom occuring associated with many psychiatric conditions or no disorder at al, and depersonalization as syndrome
While the epidemiology of depersonalisation disorder remains poorly understood, it is thought to be twice as common in women as in men (Kaplan& Sadock, 1996)
Depersonalisation disorder ICD-10 Depersonalisation disorder ICD-10 Vs DSM-IVVs DSM-IVClassinfied as
depersonalisation and derealisation syndrome
Occuring in a setting of clear consciousness with retention of insight
A disorder in which sufferer complain that his or her mental activity, body and
Depersonalisation disorder
Emphasis recurrent feeling of detachment, retention of reality testing, and resultant personal distress, all occuring in the absence of another mental disorder
Social and situational aspectsSocial and situational aspects
Frequently, the person feels that he is less able to himself, his personality, his behaviour than other people accept their own
There is barrier to his giving an account of his symptoms and this in turn is a barrier to communication in all areas of life.
Organic and psychological theories Organic and psychological theories of depersonalisationof depersonalisationThe relationship between brain pathology and
remains unclear. Depersonalisation is certainly not pathognomic of organic diseases, in fact there is no organic or psychotic abnormality in the vast majority of sufferers
The state of increased alertness observed in depersonalisation is considered by Sierra and Berrios (1998) to result from activation of prefrontal attention systems and reciprocal inhibition of anterior cingulate, leading to experience of ‘mind emptiness’ and indifference to pain
the lack of emotional colouring, reported as feelings of unreality, would be accounted for by a left-sided prefrontal mechanism with inhibition of the amygdala
derealisationderealisationFrequently depersonalisation is
accompanied by the symptoms of derealisation because– the ego and its environment are experienced as one continuous whole
The less a patient takes himself for granted the more unfamiliar and alien does the world around him become(Schrfer,1980)
desomatisationdesomatisationLocalisation to individualised
organ
Kuru, described by Yap(1965)- culture specific example, in which sufferer experiences acute anxiety, believes his penis is shrinking and fears that it will ultimately disappear
Distortion of timeDistortion of timeChange of feeling concerning the
body may be associated with distortion of time sense, the passage of time appears altered in some way: time both past and present, seems unreal to me, as if it had never happened and was never going to happen
Deaffectualisation--Loss of Deaffectualisation--Loss of emotional resonanceemotional resonanceNormal emotional resonance experiences
a series of positive and negative feeling as they encounter both animate and inanimate objects in the environment
An emotional crisis or a threat to life may lead to complete dissociation of affect, which can be regarded as an adaptive mechanism that allows the subject to function reasonably without being overwhelmed by emotion
Loss of emotional resonance is seen in—depression-depersonalisation
Depression and loss of emotional Depression and loss of emotional resonance resonance Pt has feeling that they cannot feel
Most marked when the pt with depression encounters their loved ones
If the pt has ideas of guilty, this apparent loss of feeling will make the pt feel even more guilty and morally reprehensible
Jamais vu and deja vuJamais vu and deja vuJamais vu – there is no sense of
previously having seen a well-known object
Déjà vu – where an unfamiliar object or experience seem to be familiar
These abnormalities are similar to depersonalisation and have common origin
Disturbance of awareness of Disturbance of awareness of SELF ACTIVITYSELF ACTIVITYPerception– a pt of endogenous depression
“I do not feel alive, my eyes stare like out of a corpse; I as if nowhere
Moving– a household wife suffering from a phobic neurosis said “ if I am in the street on my own, I panic, I feel as if I am falling over” schizophrenia-- delusion of control
Memorizing and imaging-- depression feels that he is unable to initiate act of memory or fantasy. Schiz this activiy when it occurs in not initiated by him but from outside himself
Loss of feeling– occurs as a common symptom in depression. “ I cannot love my husband. Nothing has happened to us. I have just lost my feeling for him”
Willing– schiz– no longer experiences his will as being his own. Commonly neurotic describe an inability to initiate activity, a feeling of powerlessness, of being ground down, in the face of life’s vicissitudes
Abnormalities of experience of one’s own activities are closely associated with mood: depressed patient believes that he is incapable of doing anything at all
Sometimes belief about initiation of activity changed(passivity experiences)
Disturbance in the Disturbance in the immediate awareness of immediate awareness of SELF-UNITY/SINGLENESS SELF-UNITY/SINGLENESS In dreams one sometimes sees
oneself, even perhaps with some surprise, in the drama
In some forms of transcendental meditation, by carrying out repetitive monotonous acts, the subject enters a self-induced trance in which he can observe himself carrying out the behavioiur
They feel as if they are two personsSeen in in psychogenic and depressive depersonlisation(the pt
may feel that they are talking and acting in an automatic way).this may lead to say as if they are two persons
individuals with appreciation needing personalities or with learning disability. May leave out the as if and say they are two persons
delusion of demonic possession( themselves and devil)
schizophrenia (may feel they are two or more people)
Autoscopy Autoscopy (heautoscopy/phantom mirror (heautoscopy/phantom mirror image)image)Autoscopy is complex psychosensorial
hallucinatory perception of one’s own body image projected into the external visual space (Lukianowicz, 1958)
“in this strange experience the pt sees himself and knows that it is he. It is not just a visual hallucination because kinesthetic and somatic sensation must also be present to give the subject that impression that the hallucination is he” (Fish, 1967 ).
The disturbance in visual perception is an essential feature. The loss of familiarity for oneself is prominent
Especially associated with disorders of parietal lobe
The double phenomenon: The double phenomenon: dopplegangerdopplegangerIt is an awareness of oneself as being both
outside alongside, and inside oneself: the subjective phenomenon of doubling
The experience occur with different conditions, or with no mental disorder et al
Six possible psychopathological explanations for phenomenon of non-organic, non-psychotic– fantasy, depersonalization, conflict, compulsive ideas, double personality(alternating states of consciousness), being doubled
dual, double or multiple dual, double or multiple personalitypersonalityVery rarely pt may complain of
experiencing multiple personalities---In multiple personality disorder(dissociative idetity disorders)
differential diagnosis– other dissociative disorders, schizophrenia, rapid cycling bipolar disorder, borderline personality disorder, malingering and complex epilepsy
Related termsDelusional misidentification or Capgras
syndromeDouble orientation; is the situation
where an individual appears to live in two worlds simultaneously– a psychotic world and the real world; for a confused patient on a psychogeriatric ward he believes both this man visiting him is the doctor and also the person come to marry him to his young wife
Disturbance of Disturbance of the the CONTINUITY/IDENTITY of CONTINUITY/IDENTITY of the selfthe selfThis disorder is characterised by changes in the
identity of self over timeThe complete alteration in the sense of identity is
exclusively psychotic A feeling of loss of continuity which is, of lesser
intensity than the psychotic change without element of passivity, may be experienced in health, and in neuroses and personality disorders
The person knows both people, before and after, are truly himself, but he feels very altered from what he was. This may occur following an overwhelmingly important life situation, or during emotional development without an outside event eg; adolescent
A part of continuity of self is accepting that the changes in one’s total state at present are due to illness. This is characteristic usually described in the mental status examination under the term insight (David, 1990)
The feeling of loss of continuity contribute to the inertia of the person with schizophrenia, and apathy of the depressive
Lack of clear sense of identity from the past continuity into the future is a strong disincentive to concerted activity
In schizophrenia They are not the same person that they
were before the illness (sense of change) may be described as--religious conversion or being born again
Following an acute shift of the illness, may describe how they seemed to pass from being one or personality to another
They may seem to be personifying natural events, seminars and historical event, animals and historical figures during the acute illness
The depressive secondary to disorder of mood, often sees no continuation into the future “everything is bleak, there is nothing to look forward to”
Possession statePossession stateAltered state of conscious awareness is
prerequisiteIt can occur in normal, healthy people in
unusual situations either as a group phenomenon(mass hypnosis) or individually
The difference between those conditions that constitute and those that may be considered as being within a cultural or religious context alone is that the former are unwanted, cause distress to the individual and those around, and may be prolonged the immediate event or ceremony at which it was induced
Near death experienceNear death experience
The most prominent clusters of symptoms seem to be depersonalisation, increased alertness and various descriptions of ‘mystic consciousness’. Out-of-body experience with autoscopy was frequent, as was passage of consciousness into a foreign region or transcendental experience
Disturbances of Disturbances of BOUNDARIES of the selfBOUNDARIES of the selfDisturbance in knowing where I ends and not I
begins One of the most fundamental of the experience is
the difference between one’s body and the rest of the world
Knowledge of what is body and what is not -- is based on the link between information from the extroceptors and the proprioceptors -- a link that is probably learned--has to be maintained constantly
The physiologic schema of the body and the continuity and integrity of memory and psychological function is the basis of awareness of the self
Seen in schizophrenia LSD intoxication– feeling of impending ego dissolution associated with the feeling of self ‘slipping away with considerable anxiety ( Anderson and Rawnsley, 1954)
Conditions disturbance of body image seen-hypnogogic state -depression(eg; face has become ugly)-schizophrenia-organic disorders
In schizophrenia In schizophrenia, the sense of invasion of
self appears to be fundamental to the nature of the condition as it experience
First rank symptoms have in common permeability of the barrier between the individual and his environment, loss of ego boundaries (Sims, 1993)
“Other people are doing things to me, events are taking place outside myself” the external observer finds a blurring or loss of the boundaries of self, which is not apparent to the patient himself
Passivity experience Passivity experience
Falsely attribute functions to not self influence from outside, which are actively coming from the inside self
Alienation of motor actions and feelings( passivity phenomenon/ made or fabricated experiences)
-- their actions are not their own-- attribute it to the hypnosis,
radiowaves, the internet, and so on--experiences these as being
made by outside influence --pt knows that all the
event around them as being made for their benefit (apophaneous experience)
In early stages of acute schizophrenia– changes in their awareness of their own activity that is becoming alienated from them(differential diagnoses: depersonalisation– they feel like machines as if their actions are carried out automatically, loss of control in obsessions and compulsions but belonging to pt)
Pt know that their actions and thoughts have excessive effects on the world around them and he experiences activity that is not directly related to them as having an effect on them
-- eg: a patient may believe that when they pass urine, they cause bad things to happen to other people
Auditory hallucinations and third Auditory hallucinations and third person auditory hallucinationperson auditory hallucinationAH confidently ascribed by the
patient to sensory stimuli outside the self, where as in fact they arise inside the self
3rd person AH– usually I think of myself n the first person singular. Occasionally I address myself in my thoughts in the second person, but I do not think about myself nor comment on my action in the third person
Hearing one’s own thoughts Hearing one’s own thoughts spoken aloud spoken aloud Implies locating one’s innermost
core experience as in distant past
Delusional perceptDelusional percept
Object of perception which is actually neutral and irrelevant to self, is delusionally interpreted as highly relevant, having intense personal meaning.
The implication is that meaning of the perception, although in reality outside self, has become incorporated within self
Thought broadcastingThought broadcasting
-- because the pt ‘knows’ that as he thinks the whole world is thinking in unison
Other alterations to Other alterations to boundaries of self– in states boundaries of self– in states of ecstasyof ecstasy Person might describe
feeling at one with universemerging with Nirvanaexperiencing unity with saints
or in oneness with GodOccur
in normal peoplein those with personality disorderas well as in sufferers from psychoses
This alteration in awareness in boundaries of self is different from that of schizophrenia. In ecstasy it is an as if experience and is mediated affectively( there is no loss of judgment, ability to discriminate)
PSYCHIATRIC PSYCHIATRIC APPLICATIONSAPPLICATIONS
Theory of mind Theory of mind (mentalisation)(mentalisation) refers to the ability of an
individual to infer or understand the mental states of others in given situation (Bentall, 2003)
Many of the disturbances in the experience of self may co-exist with deficits in theory of mind esp in the context of psychosis
Deficits in theory of mind have been particularly associated with-- autism(Baron, Cohen et al, 1993) --paranoid symptoms in psychotic illness(Frith,1992; Frith&Corcoran,1996)
Theory of mind prove valuable in informing other approaches to understanding the psychopathology of schizophrenia (Bentall,2003) or elucidating etiology
Schiffman et al (2004) - suggesting that some aspects of theory of mind may be impaired in these individuals prior to development of schizophrenia spectrum disorders
Sass & Parnas(2003) have proposed -- a unified account of symptoms in schizophrenia, in which they have emphasized the importance of abnormalities of consciousness -- argued that schizophrenia is fundamentally a self disorder characterised by particular distortions of awareness of aspects of the self. Eg: increased self-consciousness, diminished self affection
The study of consciousness, and the study of theory of mind are clearly related fields in schizophrenia research------may well play imp role in understanding clinical features of the illness
Disorders of the Disorders of the awareness awareness of the of the body(body image)body(body image)Undue concern with illness–
Hypochondriasis
Dislike of body– Dysmorphophobia, transsexualism
Undue concern with appearance– Narcissism
Distortion of body image– anorexia nervosa, obesity
