Which option describes the signs commonly associated with Parkinson's disease?

• A. Spina bifida
• B. Sciatica
• C. Subarachnoid hemorrhage
• D. Symptoms of Parkinson's disease

Answer: (D)

The signs most closely tied to Parkinson's disease are the movement-related changes that define the condition: resting tremor, slowed movement (bradykinesia), increased muscle tone (rigidity), and problems with balance and posture. These features describe how PD patients typically present and progress, making this option the best fit for “signs commonly associated with Parkinson's disease.” Spina bifida is a birth defect involving spinal formation, sciatica refers to leg nerve pain, and subarachnoid hemorrhage is bleeding around the brain with symptoms like a sudden severe headache. None of these describe the characteristic signs of Parkinson's disease, so they don’t fit as well.
