Parkinson's Parkinson's Disease Stages and Progression 1 — Questions and Answers
Question 1: The Hoehn and Yahr scale, used to measure Parkinson's disease severity, ranges from Stage 1 to Stage:
- 3
- 4
- 5 (Correct answer)
- 6
Correct answer: 5
The Hoehn and Yahr scale ranges from Stage 1 (mild, unilateral symptoms) to Stage 5 (wheelchair-bound or bedridden).
Question 2: In Hoehn and Yahr Stage 1, Parkinson's disease symptoms are characterized by:
- Bilateral motor involvement with balance problems
- Unilateral involvement only (Correct answer)
- Requiring a wheelchair for mobility
- Significant cognitive decline
Correct answer: Unilateral involvement only
Stage 1 involves unilateral (one-sided) symptoms only, such as a tremor or rigidity on just one side of the body.
Question 3: At which Hoehn and Yahr stage do bilateral (both sides of the body) motor symptoms first appear without balance impairment?
- Stage 1
- Stage 2 (Correct answer)
- Stage 3
- Stage 4
Correct answer: Stage 2
Stage 2 is marked by bilateral motor involvement but without postural instability, and the patient remains fully independent.
Question 4: Hoehn and Yahr Stage 3 is best described as:
- Bedridden and completely dependent on care
- Mild to moderate bilateral disease with some postural instability but still physically independent (Correct answer)
- Unable to walk without assistance
- Unilateral symptoms with no balance issues
Correct answer: Mild to moderate bilateral disease with some postural instability but still physically independent
Stage 3 represents mild-to-moderate bilateral disease with postural instability, but the patient can still live independently.
Question 5: Stage 5 of the Hoehn and Yahr scale is defined by:
- Mild unilateral tremor that is barely noticeable
- Independent walking with occasional balance problems
- Wheelchair-bound or bedridden unless aided (Correct answer)
- Bilateral symptoms with no balance impairment
Correct answer: Wheelchair-bound or bedridden unless aided
In Stage 5, the patient is wheelchair-bound or confined to bed and requires constant nursing care.
Question 6: On average, how long does it take for Parkinson's disease to progress from diagnosis to the most advanced stages?
- 1-2 years
- 3-5 years
- 10-20 years (Correct answer)
- 25-30 years
Correct answer: 10-20 years
Parkinson's disease typically progresses over 10-20 years, though the rate varies significantly between individuals.
Question 7: Which of the four cardinal motor features of Parkinson's disease typically appears LAST as the disease progresses?
- Resting tremor
- Postural instability (Correct answer)
- Rigidity
- Bradykinesia
Correct answer: Postural instability
Postural instability is usually the last cardinal feature to emerge and is associated with more advanced disease stages.
