Cerebellar Ataxia

DC 8004Neurological38 CFR 4.124a, DC 8004

Loss of coordination and balance caused by damage to the cerebellum, the part of the brain that controls smooth, coordinated movement. Symptoms include unsteady walking, difficulty with fine motor tasks, slurred speech, and abnormal eye movements. The VA rates cerebellar ataxia based on the severity of coordination impairment and its effect on daily functioning.

How the VA rates this condition

The VA rates this condition based on how much it affects your ability to work and carry out daily activities. The examiner will focus on the functional limitations your condition causes, not just the diagnosis itself.

Diagnostic code

DC 8004

Rating range

10% – 100%

Rating levels

Rating criteria are defined in 38 CFR 4.124a, DC 8004. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

You have total impairment from cerebellar ataxia. You are unable to walk, cannot perform daily tasks independently, and require constant assistance.

What the VA looks for

Unable to ambulate even with maximum assistance
Total loss of fine motor coordination
Severe dysarthria rendering speech unintelligible
Requires constant care for all activities of daily living
Documented need for aid and attendance

Common Pitfalls

⚠Not getting brain MRI — cerebellar ataxia requires imaging evidence showing cerebellar damage (atrophy, lesions, or infarction) to establish the objective basis for the diagnosis.
⚠Not documenting the cause and service connection — cerebellar damage can result from TBI, toxic exposure (solvents, heavy metals), infections, or stroke during or related to service.
⚠Not filing for each functional impairment separately — cerebellar ataxia can cause gait problems (rated under musculoskeletal), speech impairment, and vision problems (nystagmus), each potentially rated independently.
⚠Not describing how ataxia affects your daily life in functional terms — difficulty dressing, eating, writing, and walking should be documented with specific examples.
