Migraine Secondary to Residuals of Traumatic Brain Injury (TBI)
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Migraine when it develops after Residuals of Traumatic Brain Injury (TBI).
Why Migraine Is Linked to Residuals of Traumatic Brain Injury (TBI)

Migraine VA Rating Tiers
The VA rates Migraine the same way whether it's claimed directly or as secondary to Residuals of Traumatic Brain Injury (TBI) — severity of Migraine itself determines the percentage.
Example combined rating
40% Residuals of Traumatic Brain Injury (TBI) + 30% Migraine = 58%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 30% combine to 58%, not 70%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
Evidence for a Migraine Secondary Claim
- •Neurology consult with detailed migraine history
- •Headache diary showing frequency and impact
