Parkinson's Disease

DC 8004Neurological38 CFR 4.124a, DC 8004

A brain disorder that causes shaking, stiffness, and difficulty with walking, balance, and coordination. The VA rates Parkinson's disease based on the severity of motor symptoms and how much they limit your ability to function.

Rating Levels

Your Parkinson's disease is completely disabling. You may be bedridden, have severe dementia, or be totally incapacitated.

What the VA looks for

Bedridden or wheelchair-bound
Severe dementia or cognitive impairment
Total incapacitation requiring full-time assistance
Unable to perform activities of daily living
Severe motor symptoms uncontrolled by medication

Common Pitfalls

⚠Not documenting all motor AND non-motor symptoms — Parkinson's causes sleep problems, depression, cognitive changes, and constipation that may warrant separate secondary claims.
⚠Not having a neurologist provide regular assessments showing progression over time.
⚠Failing to document how medication side effects (dyskinesia, "on-off" episodes) contribute to functional impairment.
⚠Not describing your worst days — Parkinson's symptoms fluctuate significantly throughout the day.
