All are negative symptoms of schizophrenia except

A. Delusions are a positive symptom of schizophrenia, not a negative symptom. They are false, fixed beliefs that persist despite evidence to the contrary. Common types include persecutory, grandiose, and bizarre delusions. Positive symptoms result from excess dopamine activity in the mesolimbic pathway. B. Avolition is a negative symptom characterized by a lack of motivation to initiate and sustain goal-directed activities. It leads to difficulties with personal hygiene, work, and social engagement, significantly impairing daily functioning. C. Apathy is a negative symptom marked by a lack of interest, enthusiasm, or emotional responsiveness. Individuals with schizophrenia may show indifference to social interactions, personal achievements, or daily activities. D. Alogia (poverty of speech) is a negative symptom where individuals speak less and provide minimal verbal responses. This reflects impaired thought processing and reduced cognitive engagement, common in schizophrenia's mesocortical dopamine pathway dysfunction.
