Flashcards in Psychotic Disorders Deck (10):
1

Hallucinations, delusions, disorganized speech/behavior/affect, agitation, aggression
More prominent and get more attention
Usually occur during psychotic episodes
Usually involve distinct abnormal behaviors

positive psychotic symptoms

2

Attention deficits, asociality, anhedonia, apathy, avolition (inability to initiate and persist in goal directed activities), alogia (poverty of speech and contents), anergia
Affective flattening, diminished emotional expressiveness
A lack of something expected

negative psychotic symptoms

3

later age of onset
sudden onset
female
higher level of functioning prior to onset
good compliance
family history of mood disorders
paranoid subtypes

good prognostic factors in schizophrenia

4

early age of onset
male
more negative symptoms
more brain abnormalities
lower level of function prior to onset
substance abuse
disorganized subtype

poor prognostic factors in schizophrenia

5

1-3% prevalence, genetic and environmental components

2+ of the following (at least 1 *), each present for a significant portion of time during a 1 month period (or less if successfully treated): delusions*, hallucinations*, disorganized speech*, grossly disorganized or catatonic behavior, negative symptoms

social/occupational dysfunction with continuous signs of the disturbance persisting for at least 6 months, this 6 month period must include at least 1 month of symptoms

exclusions: no MDE, manic episode, or mixed episode have occurred with the active-phase symptoms; if mood episodes have occurred during the active-phase symptoms their total duration has been brief relative to the duration of the active and residual periods
the disturbance is not due to the direct physiological effects of a substance or medical condition

DSM 5 specifier: with catatonia

schizophrenia

6

2+ of the following (at least 1 *): delusions*, hallucinations*, disorganized speech*, grossly disorganized or catatonic behavior, negative symptoms

social/occupational dysfunction with continuous signs of the disturbance persisting for 1 day to 1 month, with an eventual return to the premorbid level of functioning

more common in women than men
personality disorders are a risk factor

exclusions: no MDE, manic episode, or mixed episode have occurred with the active-phase symptoms; if mood episodes have occurred during the active-phase symptoms their total duration has been brief relative to the duration of the active and residual periods
the disturbance is not due to the direct physiological effects of a substance or medical condition

Brief Psychosis

7

Features of schizophrenia including hallucinations, delusions, and distorted thinking as well as a mood component such as depression or mania
Presence of psychotic symptoms during a 2 week period or longer in the absence of mood symptoms, majority is illness is characterized by mood symptoms

0.5% prevalence, more common in women than men
slightly better prognosis than schizophrenia

schizoaffective disorder

8

2+ of the following (at least 1: delusions*, hallucinations*, disorganized speech*, grossly disorganized or catatonic behavior, negative symptoms

social/occupational dysfunction with continuous signs of the disturbance persisting for at least 1 month but less than 6 months
seen equally in men and women

exclusions: no MDE, manic episode, or mixed episode have occurred with the active-phase symptoms; if mood episodes have occurred during the active-phase symptoms their total duration has been brief relative to the duration of the active and residual periods

the disturbance is not due to the direct physiological effects of a substance or medical condition

schizophreniform disorder

9

Bizarre or non-bizarre delusion lasting longer than 1 month (erotomanic, grandiose, jealous, persecutory, somatic, mixed)

0.25% prevalence with a mean age of onset of 40 years
more common in women than men

hallucinations may be present but are rare

disorganized thought/behavior is usually not present

functioning is not affected except by the delusion itself

less responsive to antipsychotic medications

symptoms must not be better explained by other mental disorders

delusional disorder

10

3+ of the following:
motor immobility – catalepsy (including waxy flexibility) or stupor
excessive motor activity – apparently purposeless and not infleuenced by external stimuli
extreme negativism – apparently motiveless resistance to all instructions or maintenance of a rigid posture against attempts to be moved
peculiarities of voluntary movement – posturing (voluntary assumption of inappropriate or bizarre postures)
stereotypes movements – prominent mannerisms or prominent grimacing, echolalia, or echopraxia

catatonia
