Residual schizophrenia is a subtype of schizophrenia characterized by the absence or diminished presence of prominent psychotic symptoms such as delusions and hallucinations, while still showing some residual signs of the disorder, like negative symptoms or impairment in functioning. Individuals with residual schizophrenia may exhibit social withdrawal, lack of motivation, and cognitive deficits, which are typical of the disorder but less intense than during active phases. This condition emphasizes the chronic aspect of schizophrenia where some symptoms may persist even after acute episodes have subsided.
