Question

Which of the following is a characteristic feature of Parkinson’s disease?

• A. Bradykinesia
• B. Chorea
• C. Myoclonus
• D. Dystonia

Hint:

Parkinson’s disease core triad: Tremor (resting), Rigidity, Bradykinesia.

Answer 1

The Correct Option is A

Parkinson's disease is a progressive neurological disorder that primarily affects movement. It is recognized by several distinct symptoms, one of which is bradykinesia. Bradykinesia refers to the slowness of movement and is a hallmark of Parkinson's disease. Patients with Parkinson's disease often experience difficulty in initiating movements and performing actions efficiently.

The other options listed—chorea, myoclonus, and dystonia—are distinct movement disorders:

• Chorea: Characterized by involuntary, erratic, and jerky movements. It is not a primary feature of Parkinson's disease and is more often associated with conditions such as Huntington's disease.
• Myoclonus: Involves sudden, involuntary muscle jerks. While it can occur in various neurological conditions, it is not a defining characteristic of Parkinson's disease.
• Dystonia: Involves sustained muscle contractions, causing twisting and repetitive movements. Although dystonia can appear in Parkinson's patients, it is not as definitive of the disease as bradykinesia.

By understanding these differences, we can see that bradykinesia is the feature most commonly associated with Parkinson's disease.
