What is one of the most significant symptoms of Parkinson's disease?

Tremor is one of the most significant symptoms of Parkinson's disease, often recognized as a hallmark of the condition. This involuntary shaking or oscillation typically starts in the hands, particularly when the hands are at rest, and can impact various parts of the body as the disease progresses. The tremor associated with Parkinson's disease can affect daily activities, making it difficult for individuals to perform tasks like writing or holding objects.

Moreover, tremors in Parkinson's disease are often accompanied by other motor symptoms, such as rigidity and bradykinesia (slowness of movement), which collectively contribute to the disease's impact on movement and quality of life. This symptom helps in the clinical diagnosis of Parkinson's and is a key feature that distinguishes it from other movement disorders. Understanding the role of tremors in Parkinson's can aid in the management and treatment of the disease.
