Which statement best describes the action of anticholinergics in tremor management?

• A. They block acetylcholine to rebalance dopamine-ACh levels, effective for younger clients with tremor
• B. They increase acetylcholine to worsen tremor
• C. They cure tremor in all patients
• D. They have no effect on tremor

Answer: (A)

Anticholinergic drugs work by blocking acetylcholine at muscarinic receptors, which lowers cholinergic activity in the basal ganglia. In tremor-related conditions like Parkinsonism, there’s an imbalance: reduced dopamine relative to acetylcholine promotes tremor. By dampening acetylcholine’s influence, these medications help rebalance dopamine and acetylcholine signaling, reducing tremor. They’re particularly helpful for younger patients with tremor-dominant symptoms. They’re not curative, and they can cause bothersome side effects—especially in older adults—so they aren’t used for everyone. They do have an effect on tremor (they don’t increase acetylcholine, and they don’t worsen tremor or cure it in all cases).
