A 28-year-old man with a 3-year history of schizophrenia is being assessed for his positive and negative symptoms. Which of the following is NOT a recognized negative symptom of schizophrenia?

Explanation

## Negative Symptoms vs. Positive Symptoms in Schizophrenia **Key Point:** Negative symptoms represent a *loss or diminution* of normal psychological functions, while positive symptoms are *additions* to normal experience (delusions, hallucinations, disorganized behavior). ### Negative Symptoms (The "AAAA" Framework) | Symptom | Definition | |---------|------------| | **Alogia** | Poverty of speech; reduced quantity and quality of verbal output | | **Anhedonia** | Loss of ability to experience pleasure from previously enjoyed activities | | **Affective flattening** | Reduced or absent emotional expression and responsiveness | | **Avolition** | Loss of motivation; inability to initiate or persist in goal-directed activity | **High-Yield:** These four negative symptoms are the most commonly tested. They reflect a *deficit state* — what is missing from the patient's psychological repertoire. ### Positive Symptoms (What Is Added) - **Delusions** (persecutory, referential, grandiose, somatic, nihilistic) - **Hallucinations** (auditory most common in schizophrenia) - **Disorganized speech** (tangentiality, circumstantiality, incoherence) - **Disorganized or catatonic behavior** **Clinical Pearl:** Persecutory delusions are a *positive* symptom — they represent an *addition* of false beliefs, not a loss of function. This is the distractor that does not belong in a list of negative symptoms. **Warning:** Students often confuse the terminology. "Negative" does not mean "bad" — it means *absence* or *deficit*. "Positive" does not mean "good" — it means *presence* or *addition*. ### Diagnostic Significance **High-Yield:** DSM-5 requires ≥2 symptoms from the following for ≥1 month: 1. Delusions 2. Hallucinations 3. Disorganized speech 4. Disorganized or catatonic behavior 5. Negative symptoms At least one symptom must be delusions, hallucinations, or disorganized speech (positive symptoms). **Mnemonic:** **AAAA** = Alogia, Anhedonia, Affective flattening, Avolition (the four cardinal negative symptoms).
