Migraine VA claims: what the Board relied on in grants and denials

What the Board of Veterans' Appeals' migraine and headache decisions contained when it granted service connection and when it denied it: headaches recorded in service, medical opinions, credibility, and what denials said was missing.

How often does the Board grant migraine claims?

Of 13,198 veterans whose migraine or headache service connection claim the Board decided from 2020 to 2025, it granted 24.8%, denied 17.9% and sent 57.3% back for more development.

These are service-connection claims only. The migraine topic page also counts rating appeals and shows the conditions migraine is claimed secondary to, so its numbers are different.

What separated migraine grants from denials?

A positive nexus opinion was in 49.6% of grants and 9.8% of denials, and the Board found the veteran credible in 52.7% of grants and 10.7% of denials. With both, it granted 71.0%; with neither, 7.4%.

One count per veteran; a remand counts as not granted.

With both, the Board granted 711 of 1,001 claims. A credibility finding without a positive opinion was granted 54.1%, and a positive opinion without a credibility finding 51.9%. Most claims had neither: 8,571 veterans, of whom 636 were granted.

A negative VA exam did not end the claim: one was in 82.6% of grants, about as often as in denials. In the grants below, the Board gave such an opinion little weight when it missed headaches recorded in service or the veteran's account of when they began. A private medical opinion was in 48.7% of grants and 26.4% of denials, and the benefit of the doubt was applied in 77.8% of grants.

Can I win a migraine claim without headaches in my service records?

Yes, though a record helps. The issue caption or the Board's summary names headaches in service or a head injury for 2,432 veterans (18.4% of these claims), and the Board granted 29.6% of those, against 24.8% for all migraine claims. Without a record, the veteran's own account of when the headaches began, and a doctor's opinion that takes it into account, carry the claim.

Why are migraine claims denied?

For 2,153 denials, the Board's note named a missing medical link in 63.5% of them and the in-service event or onset in 39.7%. A missing current diagnosis came up less often (17.3%).

How migraines are rated

How are migraines rated?

Under DC 8100 in 38 CFR 4.124a, by how often prostrating attacks happen over the last several months: no compensable rating for less frequent attacks, then higher ratings for attacks averaging one every two months and once a month, and the highest rating for very frequent, completely prostrating and prolonged attacks productive of severe economic inadaptability. Other headaches, such as tension headaches, are usually rated by analogy to this code.

Read the decisions

Recent decisions, with the Board's reasoning as summarized by AI and checked against the decision text:

  • , December 2025: migraines granted; a post-deployment health assessment recorded headaches, and the Board found inadequate a VA opinion that said the service records were silent.
  • , December 2025: migraines granted on the veteran's credible account of headaches that began in service and continued, despite a negative VA opinion that did not address that history.
  • , December 2025: unspecified headaches granted on a private physician's opinion linking them to toxic exposure during service in Afghanistan; the Board found the VA examiner's opinion inadequate.
  • , December 2025: migraines denied; on several periodic health assessments the veteran denied frequent or recurrent headaches, and the service records were silent.
  • , December 2025: migraines denied; headaches were treated in service, but the veteran denied frequent headaches at separation, had no treatment after service and missed the VA exam without good cause.

What the data cannot tell you

These are what the decisions contained, not what caused the result. Some items, such as a credibility finding or the benefit of the doubt, are part of how the Board explains a grant. The evidence items were extracted by AI and apply to the whole decision, which often has other issues. "Headaches in service" is a word match on the issue caption and the Board's AI summary, so it undercounts. Rating appeals are left out. Historical outcomes, not predictions.

For representatives

  • Look for headaches in the service treatment records, including post-deployment health assessments; a VA opinion that misses them can be challenged as based on inaccurate facts.
  • Get statements on when the headaches began and how often they have come since, from the veteran and from family or fellow service members.
  • Ask for a medical opinion that accounts for that history and names the diagnosis; claims for headaches not called migraine did worse.
  • Check the separation exam and periodic health assessments; a denial of headaches there is the record the Board weighs against the claim, and it needs an explanation.
  • Make sure the veteran attends the VA exam; a missed exam without good cause can sink the claim.

About the data

Board of Veterans' Appeals decisions 2020-2025 (bva_cases_v2 lead basis): migraine or headache condition (DC 8100) service connection issues (not increased-rating, effective-date or TDIU issues). Each veteran is counted once, at the best ruling in the decision; grant share = granted / all decided, so a remand counts as not granted. Evidence flags were extracted by AI from each decision and apply to the whole decision, not one issue. Grants vs denials shows what the decisions contained, not what caused the result. Historical outcomes, not predictions. Queried November 6, 2026. Every figure in this story is computed from the query results, and the AI-extracted data can contain errors. The figures are fixed as of that date. Related research pages describe their own data dates and methods.

Where this data comes from

  1. Claim
  2. Regional office decides
  3. Veteran appeals
  4. Board decides
  5. Granted · Denied · Remanded: back to the regional office

Board of Veterans' Appeals decisions show how VA's highest review body applies 38 CFR and weighs evidence on contested claims.

Each one is an appeal: a regional office decided the claim first, and the veteran appealed. So these rates describe the Board, not a veteran's odds at the regional office, where most claims are decided and whose decisions are not public.
