individualized treatment in the community and help patients with medication adherence,
basic living skills, social support, job placements, and community resources
ƒ social skills training, employment programs, disability benefits
ƒ housing (group home, boarding home, transitional home)

36
Q

SCZ Px

A

• course is variable: some individuals have exacerbations and remissions and others remain
chronically ill; accurate prediction of the long term outcome is not possible
• early in the illness, negative symptoms may be prominent; positive symptoms appear and
typically diminish with treatment; negative symptoms may become more prominent and more
disabling
• over time: 1/3 improve, 1/3 remain the same, 1/3 worsen

37
Q

Schizophreniform

A
  • diagnosis: criteria A, D and E of schizophrenia are met; an episode of the disorder lasts from 1-6 mo. If the symptoms have extended past 6 mo the diagnosis becomes schizophrenia
  • treatment: similar to acute schizophrenia
  • prognosis: better than schizophrenia; begins and ends more abruptly; good pre- and post-morbid function
38
Q

Brief psychotic disorder - note time line

A
  • diagnosis: acute psychosis (presence of 1 or more positive symptoms in criteria A 1-4 of schizophrenia) lasting from 1 day to 1 mo, with eventual full return to premorbid level of functioning
  • can occur after a stressful event or postpartum
  • treatment: secure environment, antipsychotics, anxiolytics
  • prognosis: good, self-limiting, should return to pre-morbid function in about 1 mo
39
Q

Schizoaffective criteria

A

A. uninterrupted period of illness during which there is either a MDE, manic episode, or a mixed episode concurrent with symptoms meeting criteria A for schizophrenia
B. in the same period, delusions or hallucinations for ≥2 wk in the absence of prominent mood symptoms
C. symptoms that meet criteria for a mood episode are present for a substantial portion of total duration of active and residual periods of the illness

  • treatment: antipsychotics, mood stabilizers, antidepressants
  • prognosis: between that of schizophrenia and of mood disorder
40
Q

Delusional disorder criteria

A

A. The presence of one (or more) delusions with a duration of 1 month or longer.

B. Criterion A for schizophrenia has never been met.

Note: Hallucinations, if present, are not prominent and are related to the delusional theme (e.g., the sensation of being infested with insects associated with delusions of infestation).

C. Apart from the impact of the delusion(s) or its ramifications, functioning is not markedly impaired, and behavior is not obviously bizarre or odd.

D. If manic or major depressive episodes have occurred, these have been brief relative to the duration of the delusional periods.

E. The disturbance is not attributable to the physiological effects of a substance or another medical condition and is not better explained by another mental disorder, such as body dysmorphic disorder or obsessive-compulsive disorder.

Specify if:
With bizarre content: Delusions are deemed bizarre if they are clearly implausible, not understandable, and not derived from ordinary life experiences (e.g., an individual’s belief that a stranger has removed his or her internal organs and replaced them with someone else’s organs without leaving any wounds or scars).

Individuals with delusional disorder may be able to factually describe that others view their beliefs as irrational but are unable to accept this themselves (i.e., there may be “factual insight” but no true insight).

41
