5. Epidemiology
• Lifetime prevalence : 0.05 – 1%( osmosis) , but
according to National Institute of Mental
Health it is 0.6 to 1.9 percent.
• Men > Female. ( kaplan’s says equally
prevalent)
• Age of onset Men: 10 to 25 years
Women: 25 to 35 years
• M: more severe and poor outcome
• F: less severe and good outcome.
12. BRIEF PSYCHOTIC DISORDER
• Brief psychotic disorder is defined as a
psychotic condition that involves the sudden
onset of psychotic symptoms, which lasts 1
day or more but less than 1 month.
• Remission is full, and the individual returns to
the premorbid level of functioning.
• Brief psychotic disorder is an acute and
transient psychotic syndrome.
• More common in women than in men.
13. Schizophreniform
• Common in adolescents and young adults
• Men > women, almost 5 times
• Life time prevalence : 0.11%
• A 1 year prevalence : 0.09%
15. Diagnosis
• A diagnosis of brief psychotic disorder is
appropriate when psychotic symptoms last at
least 1 day but less than 1 month and are not
• associated with a mood disorder, a substance-
related disorder, or a psychotic disorder caused
by a general medical condition.
• There are three subtypes of brief psychotic
disorder: (1) the presence of a stressor, (2) the
absence of a stressor, and (3) a postpartum onset
16. Treatment
Pharmacotherapy
• The introduction of chlorpromazine (Thorazine) in 1952 may be the
most important single contribution to the treatment of a psychiatric
illness. Chlorpromazine was subsequently shown to be effective at
reducing hallucinations and delusions, as well as excitement. It was
also noted that it caused side effects that appeared similar to
parkinsonism.
• The drugs used to treat schizophrenia have a wide variety of
pharmacological properties, but all share the capacity to antagonize
postsynaptic dopamine receptors in the brain.
• Clozapine (Clozaril), the Orst ePective antipsychotic with negligible
extrapyramidal side ePects, was discovered in 1958 and first studied
during the 1960s. However, in 1976, it was noted that clozapine was
associated with a substantial risk of agranulocytosis.
17. HOSPITALIZATION
• Hospitalization is indicated for diagnostic
purposes; for stabilization of medications; for
patients’ safety because of suicidal or homicidal
ideation; and for grossly disorganized or
inappropriate behavior, including the inability to
take care of basic needs such as food, clothing,
and shelter.
• Establishing an effective association between
patients and community support systems is also a
primary goal of hospitalization.
• Hospital treatment plans should be oriented
toward practical issues of self-care, quality
• of life, employment, and social relationships.
18. Psychotherapy
- Cognitive Behavioral Therapy ( CBT ) for psychosis.
• CBT teaches a person to modify beliefs or behaviors that
may be leading to negative emotions. The therapy has two
main parts: a cognitive component, which helps a person to
change his or her thinking about a situation, and a
behavioral component, which helps a person to change his
or her reactions.
• is a short-term, problem-focused approach with the goal of
teaching people who have schizophrenia a variety of coping
skills to help them manage difficult situations
• a person works with a therapist to learn how his or her
thoughts, feelings, and behaviors influence each other. In
order to change unwanted feelings or problematic
behaviors, the therapist teaches strategies to modify
negative thoughts and respond to them differently.
