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. Hypertension, heart disease, and diabetes are risk factors for cerebrovascular disease, and when one of them is already service-connected, medical evidence can link the cognitive decline to it as a secondary condition. 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

RatingCriteria
100%Total occupational and social impairment, due to such symptoms as: gross impairment in thought processes or communication; persistent delusions or hallucinations; grossly inappropriate behavior; persistent danger of hurting self or others; intermittent inability to perform activities of daily living (including maintenance of minimal personal hygiene); disorientation to time or place; memory loss for names of close relatives, own occupation, or own name.
70%Occupational and social impairment, with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood, due to such symptoms as: suicidal ideation; obsessional rituals which interfere with routine activities; speech intermittently illogical, obscure, or irrelevant; near-continuous panic or depression affecting the ability to function independently, appropriately and effectively; impaired impulse control (such as unprovoked irritability with periods of violence); spatial disorientation; neglect of personal appearance and hygiene; difficulty in adapting to stressful circumstances (including work or a worklike setting); inability to establish and maintain effective relationships.
50%Occupational and social impairment with reduced reliability and productivity due to such symptoms as: flattened affect; circumstantial, circumlocutory, or stereotyped speech; panic attacks more than once a week; difficulty in understanding complex commands; impairment of short- and long-term memory (e.g., retention of only highly learned material, forgetting to complete tasks); impaired judgment; impaired abstract thinking; disturbances of motivation and mood; difficulty in establishing and maintaining effective work and social relationships.
30%Occupational and social impairment with occasional decrease in work efficiency and intermittent periods of inability to perform occupational tasks (although generally functioning satisfactorily, with routine behavior, self-care, and conversation normal), due to such symptoms as: depressed mood, anxiety, suspiciousness, panic attacks (weekly or less often), chronic sleep impairment, mild memory loss (such as forgetting names, directions, recent events).
10%Occupational and social impairment due to mild or transient symptoms which decrease work efficiency and ability to perform occupational tasks only during periods of significant stress, or symptoms controlled by continuous medication.
0%A mental condition has been formally diagnosed, but symptoms are not severe enough either to interfere with occupational and social functioning or to require continuous medication.

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. Hypertensive vascular disease is the most prevalent service-connected cardiovascular disability (845,750 among all compensation recipients, VBA Annual Benefits Report, FY2025), and if hypertension 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.
