- residual
- absence of prominent delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behaviour
- continuing evidence of disturbance indicated by the presence of negative symptoms or two or more symptoms in criteria A present in attenuated form
Clinical Pearl
Suggested Criteria for Prodromal Syndromes
- Attenuated positive symptom syndrome: Abnormal unusual thought content, suspiciousness, grandiosity, perceptual abnormalities, and/or organization of communication; onset or worsening in past year
- Brief intermittent psychotic syndrome: Frankly psychotic unusual thought content, suspiciousness, grandiosity, perceptual abnormalities, and/or organization of communication; onset in past three months
