Week 11 Schizophrenia (AJ) Flashcards
Apathy… Lack of motivation and a seeming absence of interest in or an ability to persist in what are usually routine activities, including work, school, hobbies or social activities.
Negative symptoms of Schizoprenia?
Consist of behavioural deficits: avolution, a sociality, anhedonia, blunted affect, and Alogia.
These symptoms tend to endure beyond an acute episode.
Severe impairments in social relationships. Few friends, poor social skills and little interest in being with other people like Donna and Cath.
A loss of interest in or a reported lessening of the experiences of pleasure. Two types of pleasure experiences in Anhedonia construct:
- Consummatory pleasure… Amount of pleasure experienced in the moment / in the presence of something pleasurable.
- Anticipatory pleasure…amount of expected pleasure from future events …e.g. The amount of pleasure expect to experience when Santa comes.
Refers to the outward expression of emotion… Stare vacantly, motionless muscles of the face, lifeless eyes.
Flat and toneless voice, etc..
Refers to a significant reduction in the amount of speech. Do not talk much as o,opposed to Cath and DD and AS.
Two domains of negative symptoms
Experience domain.. Motivation, emotional experience, and socialty.
Expression domain… Expression of emotion, vocalisation.
Disorganised symptoms of schizophrenia…
Include disorganised speech (formal thought disorder) and disorganised behaviour.
Disorganised speech refers to …
Problems in organising ideas and in speaking so that a listener can understand.
Speech may be disorganised by loose associations or derailment in which person may be more successful in communicating with a listener but has difficulty sticking to one topic.
What type of cognitive functioning is disorganised speech
Executive functioning … Problem solving, planning, and making associations between thinking and feeling.
Disorganised speech also related to the ability to perceive semantic information (i.e. meaning).
...inexplicable bouts of agitation ...dress unusually ...childlike/ silly manner ... Hoard food ...collect garbage ...difficulty performing basic everyday tasks.
MoVEment SymPTOms :)
Grossly abnormal psychomotor behaviour…
Catatonia is the prime example…gesture repeatedly, peculiar finger, hand, arm movements, seemingly (often) purposeful.
Catatonic immobility: adoption of unusual postures for long periods of time.

Hmm… See lecture slides for more detail… :). Unless I get the time to write the details in :)
What are the TWO brief psychotic disorders?
With a third added…
- Schizophreniform disorder ….same symptoms as schiz but last only from 1-6 months.
- Brief psychotic disorder… Lasts from 1 day to 1 month and is often brought on by extreme stress, such as bereavement.
- Scnizoaffective disorder comprises mixtures of symptoms of schizophrenia and mood disorders…may require a depressive or manic episode listed in DSM 5.
Troubled by persistent delusions of persecution or by delusional jealousy the unfounded conviction that the spouse or lover is unfaithful.
The region of the frontal lobe that helps maintain an image of threats and rewards faced, as well as maintain focus and plan relevant those threats and rewards.
Social selection hypothesis
An attempt to explain the correlation between social class and schizophrenia by arguing that people with schizophrenia tend to move downward in socioeconomic status.
Diagnosis applied when a patient has symptoms of both mood disorder and either Schizophreniform disorder or schizophrenia.
