    Area of Science:

    • Psychiatry
    • Epidemiology
    • Genetics

    Context:

    • Investigates suicide rates in a cohort of 675 patients diagnosed with functional psychoses.
    • Observational period ranged from 9 to 24 years.
    • Suicide accounted for 25.6% of all deaths within the study group.

    Purpose:

    • To determine the frequency of suicide among patients with functional psychoses.
    • To analyze suicide rates across specific diagnoses: schizophrenia, bipolar disorder, and unipolar depression.
    • To examine the prevalence of suicide among first-degree relatives of patients with these conditions.

    Summary:

    • Overall suicide frequency in functional psychoses patients was 5.5%.
    • Specific rates: schizophrenia (1.4%), bipolar disorder (2.4%), and unipolar depression (10.4%).
    • Familial suicide rates varied: relatives of schizophrenics (1.3%), schizoaffectives (3.8%), unipolar depressives (4.2%), and bipolar disorder (4.3%).

    Impact:

    • Highlights the elevated suicide risk associated with functional psychoses, particularly unipolar depression.
    • Suggests a potential genetic or environmental familial predisposition to suicide in these patient populations.
    • Identifies specific diagnostic groups and their relatives requiring targeted suicide prevention strategies.
