Which condition is characterized by motor restlessness, fidgeting, pacing, and swinging of the legs?

• A. Acute pseudo parkinsonism
• B. Adverse effects
• C. Acute akathisia
• D. Cardiovascular effects (Anticholinergics)

Answer: (C)

This describes akathisia, an extrapyramidal side effect caused by dopamine D2 receptor blockade from antipsychotic drugs. It presents with inner restlessness and observable motor activity, such as fidgeting, pacing, and swinging the legs, reflecting an urge to move and inability to stay still. This combination of subjective discomfort and objective movement is the hallmark of akathisia. Acute pseudo-Parkinsonism, in contrast, features slowed movements, rigidity, tremor, and masked facies, not the constant urge to move. The other options are too vague or refer to broad effects rather than a specific motor syndrome.
