What condition may anticholinergics be used to treat?

Anticholinergics are primarily used to treat Parkinson's symptoms due to their ability to counteract the effects of acetylcholine, a neurotransmitter that can become imbalanced in conditions like Parkinson's disease. In this context, the overactivity of acetylcholine in relation to dopamine, which is deficient in Parkinson's, can lead to symptoms such as tremors and rigidity. By blocking the action of acetylcholine, anticholinergics help to reduce these motor symptoms, providing relief to individuals suffering from the disease.

In contrast, high blood pressure is typically managed through antihypertensive medications rather than anticholinergics. Fungal infections are treated with antifungal medications, and seizures are usually managed with antiepileptic drugs. Therefore, anticholinergics play a specific role in addressing symptoms associated with Parkinson's, making it the correct choice in this context.
