Which of the following is not a characteristic symptom of Parkinson's Disease?

Rapid weight loss is not a characteristic symptom of Parkinson's Disease. The hallmark symptoms of this condition typically include hand tremors, shuffling gait, and muscle rigidity. Hand tremors are often seen as one of the most recognized symptoms, where an individual may experience involuntary shaking, particularly when at rest. A shuffling gait refers to the way individuals with Parkinson's may walk, often with a stooped posture and reduced arm swing. Muscle rigidity describes the stiffness or inflexibility of muscles, which can impact movement and lead to discomfort.

While weight loss can occur in some individuals with Parkinson's, it is not considered one of the primary symptoms directly associated with the disease itself. Instead, it may be attributed to other factors such as decreased appetite, difficulties with swallowing, or metabolic changes, but these are not defining traits of Parkinson's Disease as the other options are.
