Hoehn and Yahr Stage I is described as which?

Hoehn and Yahr Stage I is described as which?

• A. Unilateral Parkinson's symptoms, minimal/no disability.
• B. Bilateral symptoms, no postural instability.
• C. Bilateral symptoms, postural instability, physically independent.
• D. Severe disability, requires some assistance but can stand/walk unassisted.

Answer: (A)

The main idea here is understanding how the Hoehn and Yahr scale categorizes Parkinson’s disease progression. Stage I means the disease affects only one side of the body (unilateral) and there is little to no impact on daily functioning. So, signs like tremor or stiffness on just one side with minimal or no disability fit Stage I best. The other scenarios describe more advanced stages: when both sides are affected but balance isn’t yet impaired, when there’s bilateral involvement with postural instability, or when disability is already severe. That’s why unilateral symptoms with minimal or no disability is the correct description for Stage I.
