Vascular Neurocognitive Disorder — VA Disability Rating Criteria (DC 9305)
Diagnostic Code 9305 · 38 CFR §4.130
What Is It?
Vascular neurocognitive disorder (formerly called vascular dementia or multi-infarct dementia) is cognitive decline caused by cerebrovascular disease — reduced or blocked blood flow to the brain. This can result from strokes, transient ischemic attacks, or chronic small-vessel disease. Veterans are at elevated risk because of service-connected hypertension, cardiovascular disease, diabetes, and exposure to environmental toxins that damage blood vessels. Cognitive symptoms may appear gradually or in a stepwise pattern after vascular events and typically include difficulty with attention, processing speed, executive function, and memory. The VA rates this condition under the General Rating Formula for Mental Disorders at 38 CFR 4.130.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Total occupational and social impairment with severe cognitive decline, disorientation to time or place, inability to perform daily activities, severe memory loss, and need for constant supervision. |
| 70% | Deficiencies in most areas due to significant cognitive impairment. May include disorientation, inability to manage finances or medications independently, and near-continuous anxiety or depression about cognitive decline. |
| 50% | Reduced reliability and productivity due to moderate cognitive decline affecting task completion, judgment, complex instructions, and relationships. |
| 30% | Occasional decrease in work efficiency due to mild memory loss, slowed processing, difficulty concentrating, or depressed mood. |
| 10% | Mild cognitive decline that decreases work efficiency only during periods of significant stress. |
| 0% | A diagnosis exists but cognitive symptoms do not impair occupational or social functioning. |
Evidence Needed
A neuropsychological evaluation documenting cognitive decline is the strongest evidence. Brain imaging (MRI or CT) showing vascular changes — white matter lesions, lacunar infarcts, or evidence of prior strokes — supports the diagnosis. Medical records documenting the underlying vascular condition (hypertension, stroke history, cardiovascular disease) and its connection to military service establish nexus. If the vascular disease is secondary to a service-connected condition, that link must be documented. Buddy statements describing observed cognitive decline in daily functioning are valuable.
C&P Exam Tips
Describe specific cognitive changes: difficulty remembering recent conversations, trouble planning and organizing tasks, slower thinking, confusion in complex situations. Explain the timeline — when you first noticed cognitive changes and how they relate to your vascular health history. If you have had strokes or TIAs, describe those events and the cognitive changes that followed. Describe practical impacts: difficulty managing finances, trouble following multi-step instructions at work, getting confused in familiar settings.
How to File
File on VA Form 21-526EZ with DC 9305. Submit neuropsychological testing results, brain imaging reports, and records of the underlying vascular condition. If the vascular disease is service-connected or secondary to a service-connected condition (like hypertension), include that claim number. A nexus letter connecting cognitive decline to the vascular disease is essential. Include buddy statements describing cognitive decline in daily life.
Common Mistakes
Not obtaining brain imaging is a missed opportunity — MRI findings of vascular changes strongly support this diagnosis. Another mistake is not connecting the vascular disease to service. Hypertension is one of the most common service-connected conditions, and if it leads to vascular brain damage, the cognitive effects should be claimed. Attributing cognitive decline to normal aging without investigating vascular causes is a frequent error.
Frequently Asked Questions
How is DC 9305 different from DC 9304 or DC 9310?
DC 9304 covers neurocognitive disorder from traumatic brain injury. DC 9305 covers neurocognitive disorder from vascular disease specifically. DC 9310 covers unspecified causes. The rating criteria are identical for all — the distinction helps clarify the underlying cause for nexus purposes.
Can vascular neurocognitive disorder be secondary to hypertension?
Yes. If service-connected hypertension has caused cerebrovascular damage leading to cognitive decline, DC 9305 applies as a secondary claim. You need medical evidence — brain imaging and a nexus opinion — connecting the cognitive impairment to the vascular disease.
