Quizplus · Accepted Answer

Most of the brain abnormalities identified in individuals with schizophrenia are more prevalent in those with primarily negative symptoms. Negative symptoms include aspects such as lack of motivation, reduced emotional expression, and social withdrawal. These symptoms are often associated with a poorer prognosis because they can be more resistant to treatment and significantly impair functioning, which is reflected in the structural and functional brain differences observed in this subgroup. Positive symptoms, on the other hand, include hallucinations and delusions, which, while distressing, can often be more effectively managed with medication.
