Schizophrenia

Schizophrenia cases test whether the counselor can count duration, confirm functional decline, rule out mood and substance explanations, and move quickly to safety and psychiatric referral.

Criteria at exam depth. Two or more of five symptom groups, each present for a significant part of one month (less if successfully treated): delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms (diminished emotional expression, avolition). At least one must be delusions, hallucinations, or disorganized speech. Work, relationships or self-care fall markedly below the prior level (or, in youth, fail to reach expected level). Continuous signs last at least 6 months, including at least one month of active-phase symptoms; the rest may be prodromal or residual (negative symptoms or attenuated positive symptoms such as odd beliefs). Schizoaffective disorder and depressive or bipolar disorder with psychotic features are ruled out, and the disturbance is not due to a substance or medical condition. With a history of autism or childhood-onset communication disorder, schizophrenia is added only if prominent delusions or hallucinations last at least a month.

Specifiers. Course specifiers apply after one year of illness: first episode or multiple episodes (each currently in acute episode, partial remission or full remission), continuous, or unspecified. Also with catatonia and an optional current-severity rating.

Hinge differentials.

• Mood disorder with psychotic features: psychosis occurs only during mood episodes.
• Schizoaffective disorder: psychosis for at least two weeks without a mood episode, but mood episodes fill most of the illness.
• Schizophreniform / brief psychotic disorder: total duration under 6 months / under 1 month.
• Substance/medication-induced psychotic disorder: onset during or soon after intoxication or withdrawal; clears with abstinence.
• Delusional disorder: delusions only, organized thinking, functioning largely intact.
• Schizotypal personality disorder: lifelong odd beliefs below psychotic intensity.

On the NCMHCE. First assess risk: suicide (elevated, especially early in illness and after discharge), command hallucinations, and violence linked to paranoia. Arrange medical and substance rule-outs and a psychiatric referral for antipsychotic evaluation. Build engagement through a nonconfrontational stance (don't argue with delusions), then layer psychoeducation, family psychoeducation, CBT for psychosis, social skills training, supported employment, and coordinated specialty care or assertive community treatment for higher needs. Monitor adherence and side effects. Consider culture before calling a belief delusional: shared religious or cultural beliefs are not psychosis.

Clinical Pearl: Two of five symptoms with at least one core positive symptom, one month active, six months total. Psychosis confined to mood episodes is a mood disorder, not schizophrenia.
