Service-Connected Headaches: Nexus Letters for Your VA Claim
Brightview writes nexus letters for U.S. veterans. Dr. Jessica Allen drafts the medical opinion letter that links your headaches or migraines to your military service — the evidence VA raters need to grant service connection. We do not treat headaches or prescribe medication.
This page is for U.S. veterans and service members pursuing a VA disability rating for headaches or migraines. We do not diagnose or treat headaches, prescribe medication, or provide urgent medical care. If you need medical treatment, please contact the VA or your primary care provider.
VA Disability Evidence
A nexus letter links your headaches to your service
Many veterans experience headaches or migraines tied to blast exposure, TBI, service-related stress, sleep issues, or musculoskeletal injuries sustained during service. The VA requires medical evidence showing your current headache condition is "at least as likely as not" connected to your time in uniform.
A nexus letter from a licensed clinician provides exactly that — the medical opinion VA raters look for when granting service connection or a higher rating for headaches.
Common service-connected headache scenarios
- Post-TBI or blast-exposure headaches from combat or training
- Migraines that began or worsened during active duty
- Headaches secondary to service-connected PTSD, sleep apnea, or neck injury
- Chronic tension headaches tied to service-related musculoskeletal issues

What Sets a Strong Letter Apart
What makes a weak nexus letter?
Common deficiencies that weaken a medical opinion and lead to denial. Every Brightview letter is written to avoid every one of them.
Wrong Specialty
Opinion written by a provider without training in the condition at issue (e.g. a chiropractor writing a mental health nexus).
No Records Reviewed
The letter doesn't indicate that service, VA, or private medical records were actually reviewed.
No Clear Standard of Proof
Fails to use the VA legal standard 'at least as likely as not' — or misuses it.
Conclusory Opinion
Bottom-line conclusion with no reasoned explanation or supporting analysis.
No Medical Rationale
No explanation of how or why the claimed condition is related to service or to a service-connected disability.
No Supporting Literature
No citations to medical studies, DSM criteria, or other evidence-based sources.
Ignores Symptom Timeline
Does not discuss onset, progression, chronicity, or relevant chronology.
Relies Mainly on Self-Report
Heavy reliance on the veteran's statements without independent verification.
No Functional Impact Discussion
Does not address occupational or social impairment or functional effects of the condition.
No Differential / Alternative Cause Analysis
Does not consider other possible causes or risk factors for the condition.
A strong nexus letter uses the right specialist, explains the rationale, and is grounded in records and credible medical literature — the standard every Brightview letter is written to.
Secondary Pathways
Headaches secondary to other service-connected conditions
Most headache claims we win are secondary claims. If you're already service-connected for one of the conditions below, your headaches may be too.
VA Rating Criteria
VA migraine headache ratings
Diagnostic Code 8100 — evaluated by frequency of prostrating attacks.
| Rating | Criteria |
|---|---|
| 0% | Less frequent attacks than the criteria for 10%. |
| 10% | Characteristic prostrating attacks averaging one in 2 months over the last several months. |
| 30% | Characteristic prostrating attacks occurring on an average of once a month over the last several months. |
| 50% | Very frequent completely prostrating and prolonged attacks productive of severe economic inadaptability. |
Source: 38 CFR § 4.124a, DC 8100. Individual results depend on the medical evidence in your record.
Downstream Effects
Service-connected migraines can lead to depression and anxiety
Chronic migraine headaches disrupt sleep, work, and relationships. Over time, that impact can cause or worsen depressive and anxiety disorders. Brightview writes nexus letters for that connection too — see our depression nexus letter page or our anxiety nexus letter page.
