BVA decisions by condition
Dementia: BVA grant rates and what wins
From 2018 to 2026, the Board of Veterans' Appeals decided a dementia issue in 1,262 decisions. It granted the dementia issue in 17.0% of them, below the 19.9% grant rate for all conditions, denied it in 27.8%, and remanded it in 53.5%. Counting only decisions on the merits (granted or denied), 37.9% were granted.

Evidence in granted and denied dementia decisions
For each kind of supporting evidence: how often the Board granted the dementia issue on the merits when the decision mentioned it, compared with decisions that did not. These are associations, not causes, and evidence is recorded per decision, not per issue.
| In the record | Decisions | Granted when present | When absent | Difference |
|---|---|---|---|---|
| Positive nexus opinion | 255 | 80.6% | 17.9% | +62.6 pts |
| Favorable VA exam | 164 | 80.6% | 27.8% | +52.8 pts |
| Treating physician opinion | 82 | 79.2% | 34.0% | +45.1 pts |
| Claimed as secondary | 510 | 65.1% | 21.9% | +43.2 pts |
| Private medical opinion | 417 | 55.3% | 24.6% | +30.7 pts |
| Combat service | 94 | 48.9% | 36.9% | +12.1 pts |
| Buddy statement | 42 | 47.4% | 37.5% | +9.8 pts |
| Lay statement | 904 | 32.2% | 56.4% | −24.2 pts |
- The Board applied the benefit-of-the-doubt rule (38 CFR 3.102) in 71.0% of the decisions that granted dementia.
- The Board found the veteran's statements credible in 16.4% of grants and 8.8% of denials.
Negative evidence in the record
An unfavorable exam or a negative nexus opinion often sits in the same record as favorable evidence, and the Board weighs them against each other. So these rows show how often dementia was still granted when the record contained the negative item, not that the item helped.
| In the record | Decisions | Granted when present | When absent | Difference |
|---|---|---|---|---|
| Unfavorable VA exam | 797 | 34.9% | 44.6% | −9.7 pts |
| Negative nexus opinion | 595 | 33.1% | 43.3% | −10.2 pts |
Why the Board granted or denied dementia
Most common reasons in grants
- Current diagnosis established32
- Caused by the service-connected disability20
- Service connection established9
- Aggravated by the service-connected disability6
- Service records negative or silent2
- Criteria for service connection met2
- Favorable VA medical opinion2
- Secondary to parkinson's disease2
Most common reasons in denials
- Preponderance of the evidence against the claim41
- No current diagnosis39
- No in-service complaints, treatment or diagnosis38
- Service records negative or silent30
- Current diagnosis established22
- VA examiner: less likely than not related to service21
- No continuity of symptomatology8
- Evidence persuasively weighs against service connection7

How these numbers are calculated
- Rates count decisions in which the Board decided a dementia issue, by the outcome of that issue. Other issues in the same decision can have different outcomes.
- “Granted on the merits” leaves out remands and dismissals. “All conditions” is the grant share across every condition issue in the data.
- The data comes from CaseScribe's AI extraction of public BVA decisions (2018–2026) and can contain errors. It is updated automatically as new decisions are added.
