Board Decision Lookup › Memory loss / cognitive
How the Board ruled on memory loss and cognitive claims, 2021–2025
How the Board of Veterans' Appeals ruled on memory loss and cognitive service-connection claims in 2021–2025, for every theory and secondary pairing we publish. Board-appealed cases only, counted per claim. Last updated October 4, 2026.
These are past Board decisions, not a prediction for any individual case, and not legal advice. The percentage is among DECIDED cases; cases sent back to VA (remanded) are counted separately.

Memory loss / cognitive (direct service connection)
Direct (began in or was caused by service), or theory not stated in the Board order
21.8% granted of 262 decided cases (margin of error 17.2–27.1%). 57 granted, 205 denied, 356 sent back to VA (remanded, not decided), 65 dismissed.
What convinced the Board in granted cases
- The Board gave great weight to favorable opinions that reviewed the full record, used an accurate history such as in-service head injuries, and cited medical literature. (4 of 12 decisions read; e.g. A24011358, 23005751, 21026152)
- Negative VA opinions lost weight when they ignored the veteran's reports of memory problems since service, relied only on missing service records, or failed to address conflicting treatment records. (3 of 12 decisions read; e.g. 21056382, A24005485, 21026152)
- The Board accepted veterans' and families' credible accounts of in-service head injuries and memory problems that began or grew over time after service. (3 of 12 decisions read; e.g. A21001173, 23005751, 21056382)
Common reasons in denied cases
- Most denials found no separate memory disability: memory problems were already part of a service-connected PTSD or psychiatric rating, or no memory disorder was diagnosed. (8 of 14 decisions read; e.g. A25029196, 22040414, 23030756)
- Thorough VA opinions found no link to service or a service-connected condition, sometimes tying memory loss to a non-service-connected cause, and no medical opinion said otherwise. (4 of 14 decisions read; e.g. 22052197, 22000144, 21035727)
- The veteran's own belief about having a memory disorder, or about its cause, was not competent medical evidence. (4 of 14 decisions read; e.g. A24060047, A22016052, 22000144)
Memory loss / cognitive (exposure claims)
Exposure (e.g. Agent Orange, Camp Lejeune, burn pits)
13.3% granted of 30 decided cases (margin of error 5.3–29.7%). 4 granted, 26 denied, 46 sent back to VA (remanded, not decided), 5 dismissed.
What convinced the Board in granted cases
- Negative VA opinions lost weight when they wrongly said there was no cognitive diagnosis despite records showing one, or never addressed whether the memory loss fit a Gulf War multisymptom illness. (2 of 4 decisions read, few decisions; e.g. 22035810, 21013659)
- One grant followed proof of qualifying exposure, which gave weight to a private opinion that had been discounted when exposure was unproven; another granted dementia from Camp Lejeune water without reasoning shown. (2 of 4 decisions read, few decisions; e.g. A23005331, A24000887)
Common reasons in denied cases
- Most denials found no diagnosed memory or cognitive disorder, sometimes after normal or invalid cognitive testing. (6 of 13 decisions read; e.g. 21062955, A25004267, 21034902)
- Memory problems were attributed to another diagnosed condition, such as PTSD, anxiety, or a psychiatric disorder, rather than to an exposure or undiagnosed illness. (3 of 13 decisions read; e.g. A21000761, 22010741, 21076626)
- Thorough VA opinions weighed against the claim, and the veteran's own belief about the cause was not competent medical evidence. (4 of 13 decisions read; e.g. 21031030, 21076626, 21022149)
Memory loss / cognitive secondary to any service-connected condition
Secondary (caused or worsened by a service-connected condition)
58.7% granted of 75 decided cases (margin of error 47.4–69.1%). 44 granted, 31 denied, 105 sent back to VA (remanded, not decided), 9 dismissed.
What convinced the Board in granted cases
- Private opinions carried the most weight when they gave a fully explained rationale grounded in the veteran's history and medical research, such as how hearing loss, TBI or high blood pressure leads to or worsens dementia. (5 of 10 decisions read; e.g. A24032363, A24060419, 22041068)
- VA opinions lost ground when they ignored the absence of other risk factors, skipped whether the condition was worsened, or could not answer without speculating. (2 of 10 decisions read, few decisions; e.g. A24032363, 24025629)
- Grants also came when an opinion explained a specific mechanism, such as low oxygen from sleep apnea or vascular risk from high blood pressure and stroke, and no competent opinion contradicted it. (3 of 10 decisions read; e.g. 24025629, A25033483, 24025877)
Common reasons in denied cases
- Most denials found no current diagnosed cognitive disability: memory complaints alone were symptoms, not a disability, and a doctor's note listing symptoms without a diagnosis had little value. (6 of 12 decisions read; e.g. 21020208, 21075114, 21029994)
- A reasoned VA opinion that attributed the cognitive decline to another cause, such as brain atrophy, genetics or a different disease, outweighed the claim. (3 of 12 decisions read; e.g. 22060624, 24016727, 24025187)
- Some claims failed because the memory problems were already a compensated part of a service-connected condition like PTSD, or the claimed primary condition was not service-connected. (3 of 12 decisions read; e.g. A23022798, 21048409, 22018777)
Memory loss / cognitive secondary to PTSD
Secondary (caused or worsened by a service-connected condition)
Small sample: 11 decided cases, too few for a reliable percentage. 8 granted, 3 denied, 5 sent back to VA (remanded, not decided), 1 dismissed.

Percentages are shown only for combinations with at least 30 decided cases (granted + denied). Named secondary pairings with 10–29 decided cases are listed as "small sample" with counts only. "ANY service-connected condition (all combined)" pools every secondary claim for that condition. Other combinations exist, but there are too few decided cases to report. Each claim is counted by the Board's ruling on that specific claim (a decision covering several issues is split by issue). Remanded = sent back to VA for more work, not decided. "What convinced the Board" summarizes a reading of up to 25 granted and 25 denied Board decisions for each claim type, with the decision numbers shown so any point can be checked. Board-appealed cases only, not regional-office decisions. Information only, not legal advice. Flat Rate Nexus is a private medical practice, not affiliated with the VA.
