Medical Pharmacology Chapter 16:  Pharmacology of Antipsychotics Drugs

Clinical Cases

• Case 6: Family environment and relapse

  • A 23‑year‑old woman had a first psychotic episode 1 year ago, stabilized on antipsychotics, and completed a family psychoeducation program with her parents.

    • Over the last 3 months, her father has become increasingly critical, frequently telling her she is “lazy” and “not really sick,” and arguing about her reduced work hours.

    • She reports increased anxiety and has begun hearing a whispering voice occasionally when stressed, though not daily.

    • Questions

      • What family‑related construct is illustrated here, and how does it relate to relapse risk?

      • What early warning sign of relapse is already present?

      • From a management perspective, what steps would you take now to reduce the risk of a full relapse?

    • Explained answers

      • Construct: Expressed emotion (EE)

        • Her father’s pattern (critical, hostile comments, minimizing her illness) reflects high expressed emotion, a family environment that is consistently associated with higher relapse rates in psychosis and FEP.

        • High EE increases stress and can trigger symptom exacerbations, especially when patients are still vulnerable within the “critical period” after FEP.

      • Early warning sign

        • The re‑emergence of intermittent whispering voices under stress is a classic early warning sign of psychotic relapse, particularly in a patient with prior auditory hallucinations.

        • The temporal link between increased family criticism and symptom reappearance highlights the interaction between environment and vulnerability.

      • Management steps

        • Rapidly involve the family again: booster sessions of family intervention/psychoeducation emphasizing EE, illness course, and relapse prevention.

        • Strengthen stress‑management and coping skills with the patient (CBT‑p, coping plans for voices).

        • Review medication adherence and consider minor dose adjustment if warranted, balancing side effects with relapse risk.

        • Develop an explicit relapse prevention plan with patient and family (early‑warning sign checklist, agreed‑upon actions when signs appear).
