Which symptom is commonly associated with Parkinson disease?

Fine tremors and muscular weakness are hallmark symptoms of Parkinson's disease. This progressive neurological disorder primarily affects movement. The fine tremors often start in one hand and can be noticeable when the individual is at rest. Muscular weakness also develops as the disease progresses, affecting balance and coordination, leading to difficulties in performing everyday tasks.

In contrast, loss of vision, sudden changes in speech, and severe abdominal pain are not typically associated with Parkinson's disease. While some patients may experience changes in voice or speech as the disease progresses, these changes are not primary symptoms. Abdominal pain can result from various unrelated conditions, and visual impairment is generally associated with other diseases rather than Parkinson's itself.
