What motor symptom is often seen in Parkinson's disease?

Tremor is a classic motor symptom associated with Parkinson's disease, characterized by involuntary, rhythmic shaking motions that typically begin in the hands. This symptom is often most noticeable when the person is at rest, known as "resting tremor," and can decrease with purposeful movement. It is considered one of the hallmark signs of Parkinson's and can significantly impact daily activities and overall quality of life.

In Parkinson's disease, the tremor can occur alongside other symptoms such as bradykinesia (slowness of movement) and rigidity (muscle stiffness). The presence of a tremor, especially when it occurs on one side of the body, is often a key indicator during the clinical assessment of the disease.

The other symptoms listed, such as spasticity, ataxia, and akinetic mutism, are not typically seen in Parkinson's disease. Spasticity is more associated with upper motor neuron lesions, ataxia relates to coordination issues often seen in cerebellar disorders, and akinetic mutism involves profound unresponsiveness rather than the characteristic motor symptoms of Parkinson's.
