What are some signs and symptoms of Parkinson's disease?

The signs and symptoms of Parkinson's disease typically include impaired motor function, such as tremors, rigidity, and bradykinesia (slowness of movement), alongside non-motor symptoms like personality changes, depression, and cognitive decline. The presence of both motor and non-motor symptoms emphasizes how Parkinson's affects a person's overall functioning and quality of life. Impaired motor function directly relates to the characteristic symptoms of the disease, which progress over time and impact daily activities.

In contrast, while tremors are a well-known symptom of Parkinson's, they alone do not encompass the breadth of the disease's manifestations. Therefore, stating "only tremors" does not accurately reflect the complexity of the condition. Severe headaches are not typically considered a primary symptom of Parkinson's disease, and a complete loss of sensory function is more indicative of other neurological conditions rather than Parkinson's. Thus, the most comprehensive answer, which captures the essential aspects of the disease, includes both impaired motor function and personality changes.
