A complex mental health condition combining features of schizophrenia and mood disorders
1. Definition & Diagnostic Criteria (DSM-5)
Schizoaffective Disorder is characterized by:
✅ Psychotic symptoms (hallucinations/delusions) AND
✅ Mood episodes (major depressive or manic) occurring:
- Concurrently with psychotic symptoms AND
- Independently for ≥2 weeks
Two Subtypes:
- Bipolar Type (with manic episodes)
- Depressive Type (only depressive episodes)
Key Distinction from Schizophrenia:
Mood episodes are more prominent and prolonged.
2. Symptoms Breakdown
| Symptom Category | Psychotic Features | Mood Features |
|---|---|---|
| Bipolar Type | Delusions, disorganized speech | Mania: Hyperactivity, euphoria |
| Depressive Type | Hallucinations, paranoia | Depression: Hopelessness, low energy |
Cognitive Symptoms:
- Memory/attention deficits
- Impaired decision-making
3. Causes & Risk Factors
- Genetics: Strong family history of schizophrenia or bipolar disorder.
- Brain Chemistry: Dopamine/serotonin imbalances.
- Environmental: Childhood trauma, substance use (especially cannabis).
Myth Buster:
❌ “This is just schizophrenia + depression” → False. It’s a distinct diagnosis with different treatment needs.
4. Diagnosis Challenges
Often misdiagnosed as:
- Bipolar disorder with psychotic features
- Schizophrenia
- Major depressive disorder with psychosis
Diagnostic Process:
- 2+ weeks of psychotic symptoms without mood episodes (to rule out mood disorders).
- Mood episodes must dominate the clinical picture.
5. Treatment Approach
A. Medications
- Antipsychotics (e.g., Risperidone, Quetiapine) – For psychosis.
- Mood Stabilizers (e.g., Lithium) – For bipolar type.
- Antidepressants (e.g., SSRIs) – For depressive type (used cautiously).
B. Therapies
- CBT for psychosis (addresses delusional thinking).
- Family-focused therapy (improves communication).
- Social skills training.
C. Lifestyle Management
- Sleep regulation (critical for mood stability).
- Substance avoidance (alcohol/drugs worsen symptoms).
6. Prognosis
- Better than schizophrenia but worse than pure mood disorders.
- Relapse rates high without consistent treatment.
- Key predictors of recovery: Early intervention, social support.
7. How to Support Someone
✅ Help track symptoms (mood/psychosis cycles).
✅ Encourage medication adherence (often complex regimens).
✅ Learn crisis signs (e.g., suicidal thoughts, extreme paranoia).
❌ Avoid: Dismissing hallucinations as “just imagination.”
