Correct Answer is A
Explanation
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.
Correct Answer is D
Explanation
A. Mesolimbic pathway is responsible for reward, motivation, and emotion. In schizophrenia, hyperactivity of this pathway leads to positive symptoms such as hallucinations, delusions, and disorganized thinking.
B. Nigrostriatal pathway regulates motor control. Dopamine blockade in this pathway leads to extrapyramidal symptoms (EPS) such as tremors, rigidity, and tardive dyskinesia, which are side effects of first-generation antipsychotics (typical antipsychotics).
C. Tuberoinfundibular pathway controls prolactin secretion. Dopamine inhibits prolactin release, so blocking D2 receptors with antipsychotics leads to hyperprolactinemia, causing gynecomastia, galactorrhea, and menstrual irregularities.
D. Mesocortical pathway is responsible for cognition, motivation, and emotional regulation. In schizophrenia, hypoactivity of this pathway is linked to negative symptoms such as apathy, anhedonia, social withdrawal, and cognitive impairment. Antipsychotics that block dopamine further worsen these symptoms, making negative symptoms more difficult to treat.
