Stage 2 Parkinson's disease is characterized by which description?

• A. Mild symptoms with unilateral signs
• B. Mild symptoms with bilateral/midline signs
• C. Moderate symptoms with loss of balance
• D. Severe symptoms with inability to live independently

Answer: (B)

In Parkinson’s disease staging, the description that fits Stage 2 is mild symptoms with signs on both sides of the body but without impairment of balance. This reflects bilateral involvement without balance problems, meaning the person can still stand and walk without instability, and remains functionally independent for daily activities.

Why the other descriptions don’t fit: unilateral signs indicate Stage 1, where symptoms are on one side only. Postural instability or balance impairment begins to appear in Stage 3, so “loss of balance” describes a more advanced stage. Severe disability with inability to live independently aligns with Stage 4 or 5, where major functional dependence or wheelchair confinement occurs.
