What symptom is often NOT associated with Parkinson's disease?

Memory loss is often not directly associated with Parkinson's disease. While cognitive changes and some degree of memory impairment can occur in individuals with Parkinson's, they are more closely related to advanced stages of the disease or the presence of Lewy body dementia rather than being a core symptom of the condition.

Parkinson's disease is characterized primarily by motor symptoms that stem from the degeneration of dopaminergic neurons in the substantia nigra. Resting tremors, rigidity, and slowed movements (bradykinesia) are hallmark symptoms that define the disorder. Resting tremors typically manifest when a person is at rest and diminish with voluntary movement. Rigidity refers to muscle stiffness that can affect the limbs and trunk, leading to discomfort and decreased mobility. Slowed movements are a result of the decreased dopamine levels, which impact motor control and the initiation of voluntary actions.

In contrast, while memory loss can occur as a secondary effect of the disease progression or as part of the side effects of treatments, it is not considered one of the primary symptoms of Parkinson's disease itself. Thus, it is more accurate to state that memory loss is not typically associated with the core motor features of Parkinson's.
