Abnormal perceptions:

A category of disturbances which includes:

- Sensory disturbance.
- False perception.



Changes in the perceived intensity as quality if a real external stimulus.



Associated with organic conditions and drug ingestion or withdrawals.



Examples include:

- Hyperacusis



hearing sound as abnormally loud.



"wrong end of the telescope effect", perceiving objects which are close

False perceptions: internal perceptions which do not have a corresponding object in the
external or "real" world, Includes: Hallucinations, and Pseudo-hallucinations.

Hallucinations:



An internal percept without a corresponding external object.



The subjective experience of hallucination is that of experiencing a normal percept in

A true hallucination will be perceived as in external space, distinct from imagined
images, outside conscious control, and as possessing relative permanence.



A pseudo-hallucination will lack one or all of these characteristics.



Hallucinations are subdivided according to their modality of sensation and may be:
auditory, visual, gustatory, tactile, olfactory, or kinesthetic.



Auditory hallucination (voices)  schizophrenic patient.



Visual hallucination  organic illness.

Pseudo-hallucination:

First-rank symptoms of schizophrenia:

A group of symptoms originally described by Schneider which are useful in the diagnosis of
schizophrenia.

They are neither pathognomonic for, nor specific to, schizophrenia and are also ssen in
organic and affective psychoses.

They are 11 symptoms in 4 categories:



Auditory hallucination:
o  Voices heard arguing.
o  Thought echo.
o  Running commentary.



Delusions of thought interference:
o  Thought insertion.
o  Thought withdrawal.
o  Thought broadcasting.



Delusions of control:

o  Passivity of affect.
o  Passivity of impulse.
o  Passivity of volition.
o  Somatic passivity.



Delusional perception:
o A primary delusion of any content that is reported by the patient as having arisen

following the experience of a normal perception.

emotions (passivity of affect), to desire to do things (passivity of impulse), to perform
actions (passivity of volition), or to experience bodily sensation (somatic passivity).

response to a particular event or situation.
