If your headache claim was denied, rated at 0%, or you're not sure how to prove your headaches are connected to your service, you are not alone — and the problem usually isn't your symptoms. It's the missing medical link between those headaches and either your military service or a condition the VA has already service-connected. That link is what a nexus letter provides. Below, we explain how the VA actually rates headaches, why so many claims fall short, and how an independent medical opinion can strengthen yours.
How the VA Rates Headaches and Migraines
The VA evaluates migraines and headaches under 38 CFR § 4.124a, Diagnostic Code 8100. Ratings run from 0% to 50%, and the single word that drives almost every decision is "prostrating." A prostrating attack is one severe enough that you have to stop what you're doing and lie down or rest until it passes. The VA cares less about your daily pain level than about how often an attack completely stops your day.
The tiers break down like this:
- 50% — Very frequent, completely prostrating and prolonged attacks that produce "severe economic inadaptability" (meaning they seriously interfere with your ability to work — not that you're totally unemployable).
- 30% — Characteristic prostrating attacks occurring on average about once a month over the last several months.
- 10% — Prostrating attacks averaging about one every two months.
- 0% — Less frequent attacks. This pays nothing, but it still establishes service connection, which protects you if your headaches worsen later.
Why Headache Claims Get Denied or Underrated
Headaches are one of the most commonly underrated conditions the VA sees, and the reasons are almost always the same:
• The records don't use the right language. If your treatment notes say "reports headaches" but never describe you stopping activity, lying down, or missing work, the VA has nothing to hang a compensable rating on. The word "prostrating" doesn't have to appear, but the description of prostration does.
• There's no proof of a link to service. You may clearly have headaches now, but the VA needs a medical opinion connecting them to your service or to a service-connected condition. Without that bridge, the claim stalls.
• The frequency isn't documented over time. A single bad-day note isn't enough. The VA wants to see a consistent pattern over several months.
• The work impact is invisible. Missed shifts, leave slips, and reduced hours are some of the strongest evidence for a 30% or 50% rating, and most veterans never submit them.
The Two Pieces That Actually Win Headache Claims
1. Questionnaire / DBQ data. A Disability Benefits Questionnaire (DBQ) is the VA's own structured form for capturing the frequency, duration, and severity of your attacks. It translates your experience into the exact categories the rater is looking for. But a DBQ on its own often documents that you have headaches without fully explaining why they're connected to your service.
2. A nexus letter. This is where the DBQ falls short and a nexus letter fills the gap. A nexus letter is an independent medical opinion that explains, in clear medical terms, the connection ("nexus") between your headaches and your service — or between your headaches and a condition the VA has already service-connected, such as PTSD, a mental health condition, a traumatic brain injury, neck/cervical spine problems, or medication side effects. It gives the rater the reasoning they need to grant or increase your claim.
Used together, the DBQ shows the what and how often, and the nexus letter shows the why it's connected. That combination is what moves a headache claim forward.

Headaches Connected to Other Service-Connected Conditions
Many veterans don't realize their headaches may be claimable as secondary to a condition they're already rated for. Chronic headaches are frequently linked to PTSD and other mental health conditions, to traumatic brain injury, to cervical spine issues, and to the medications used to treat those conditions. If you're already service-connected for one of these, your headaches may be connectable through a secondary nexus opinion — even if you were never treated for headaches while on active duty.
For many veterans, chronic headaches—whether tension-type, post-traumatic, or migraine—are a debilitating part of daily life. Yet, getting these conditions service-connected through the VA can be a frustrating process. One powerful way to improve your chances of a successful claim is by including standardized headache questionnaires and a nexus letter that clearly documents how your headaches are tied to your military service.
In this post, we’ll walk you through the most commonly used questionnaires for assessing headache-related disability and show you how they can be used to support your VA claim—especially when included in a nexus letter from a psychiatrist. We’ll also touch on how these same tools can help support claims for depression secondary to headaches, a common but often overlooked avenue for additional service connection.
Why Are Questionnaires Important?
The VA often looks for objective evidence that your condition affects your quality of life and daily functioning. This is where standardized tools come in. These questionnaires provide quantifiable, research-backed data to show how your headaches interfere with your work, relationships, physical activities, and emotional well-being.
Including this data in your VA claim—or better yet, in a professionally written nexus letter—can strengthen the credibility of your case and demonstrate that your condition is both disabling and persistent.
Key Questionnaires for Veterans With Headaches
Here are several validated tools commonly used in clinical practice to measure headache impact:
1. Migraine Disability Assessment Scale (MIDAS)
This 5-item questionnaire assesses how migraines have interfered with work, school, and social activities over the past three months.
👉 Take it here: MIDAS Questionnaire – American Migraine Foundation
2. Headache Impact Test (HIT-6)
The HIT-6 measures the social, psychological, and physical effects of headaches. It’s commonly used to evaluate the severity of headache-related disability.
👉 Take it here: HIT-6 Questionnaire – QualityMetric
3. Migraine Specific Quality of Life Questionnaire (MSQ)
This tool focuses on how migraines affect daily functioning, including work performance and social interactions.
4. Chronic Headache Impact Questionnaire (CH-QLQ)
Though less commonly used, this tool evaluates the broader impact of chronic headaches on multiple life domains and can be particularly helpful for those with frequent, non-migraine headaches.

Filing for Depression Secondary to Headaches
Many veterans who live with chronic headaches also experience depression, anxiety, or emotional withdrawal as a result. If your headaches have contributed to or caused mood symptoms, you may be eligible to file a secondary claim for depression.
The same questionnaires mentioned above can support this claim. High scores on tools like the MIDAS or HIT-6 demonstrate not only physical impairment, but also emotional and psychological burden, such as:
• Withdrawing from social activities
• Reduced productivity at work
• Feelings of helplessness or irritability
• Sleep disturbance and fatigue
In these cases, a psychiatrist-written nexus letter can articulate the relationship between chronic pain and mood disturbance, helping establish a clear medical link between your service-connected headaches and your depression diagnosis.
How a Psychiatrist Can Help: Nexus Letters With Clinical Depth
While any licensed medical provider can write a nexus letter, a psychiatrist offers a distinct advantage—especially in cases involving both chronic pain and mental health. Psychiatrists are trained in both neurology and behavioral medicine, enabling us to evaluate the complex interplay between physical and psychological symptoms.
A comprehensive nexus letter from a psychiatrist can:
• Diagnose psychiatric conditions caused or aggravated by chronic headaches
• Explain how headaches impair functioning across social, emotional, and occupational domains
• Interpret questionnaire results in a clinical context
• Address overlapping symptoms (e.g., insomnia, irritability, concentration difficulties)
• Link the veteran’s headaches and resulting depression in a medically supported manner
By combining medical history, standardized measures, and expert analysis, a nexus letter becomes a powerful tool for securing and expanding VA disability compensation.

Frequently Asked Questions
Does a nexus letter guarantee my claim will be approved? No — and any provider who promises approval should be a red flag. The VA makes the final decision on your claim. What a strong, well-reasoned independent medical opinion does is give the rater the clear medical link the file was missing.
My headache claim was already denied. Can you still help? Often, yes. Many veterans come to us after a denial or a low rating. An independent opinion can address the specific gap the VA identified and support an appeal or a supplemental claim.
Can you connect my headaches to my PTSD or another rated condition? If the medical evidence supports it, yes. Headaches are frequently claimed as secondary to PTSD, mental health conditions, tinnitus, TBI, and cervical spine problems. We'll tell you honestly on the call whether a secondary opinion fits your case.
Do I need to have been treated for headaches while on active duty? Not necessarily. Secondary and delayed-onset claims are common. We'll review your records and discuss your options.
