Which of the following is NOT an extrapyramidal symptom?

Explanation:
Extrapyramidal symptoms are movement-related side effects caused by dopamine D2 receptor blockade in the nigrostriatal pathways, leading to motor abnormalities such as restlessness (akathisia), tremor, and dystonia. Dry mouth, by contrast, is an anticholinergic effect that affects salivary glands and is a non-motor symptom. Since dry mouth does not involve the motor pathways affected in extrapyramidal symptoms, it is not an EPS.
