When a veteran in your family is diagnosed with dementia, the Department of Veterans Affairs (VA) rates it as a disability only if it is service-connected, meaning linked to military service., So is dementia a VA disability when it simply came with age? Not by itself, because age alone doesn't link it to service. For most families deciding whether a claim is worth filing, the real question is whether a service-connected brain injury or another service-connected condition caused the dementia or made it worse.

Is Dementia a VA Disability? The Short Answer

It can be, and for some families it's worth pursuing. But VA disability compensation isn't paid for a diagnosis. VA describes a service-connected condition as an illness or injury that was caused by, or got worse because of, active military service.

That's why a veteran's age, on its own, doesn't open this door. Under 38 CFR 4.19, VA may not consider age as a factor in evaluating a service-connected disability; age matters only for disability that didn't result from service, which is the territory of VA pension. The flip side: once dementia is service-connected, being 80 doesn't count against the rating.

If the dementia can't be connected to service, you haven't hit a wall. The caregiver stipend covered below doesn't require the dementia itself to be service-connected, and the VA dementia and Alzheimer's care guide covers other care programs that don't hinge on a compensation claim.

When Dementia Counts as Service-Connected

VA's regulation on secondary service connection, 38 CFR 3.310, gives families three distinct paths for dementia, and VA's general service-connection rules add a fourth.

Route Regulation What must be shown What can trip it up
TBI presumption 38 CFR 3.310(d)(1) Service-connected TBI, then presenile dementia of the Alzheimer type, frontotemporal dementia, or dementia with Lewy bodies manifest within 15 years Applies only after a moderate or severe TBI, and VA can rebut it with clear evidence to the contrary
Secondary service connection 38 CFR 3.310(a) Dementia is proximately due to or the result of a service-connected disease or injury No presumption: the evidence has to show the link
Aggravation 38 CFR 3.310(b) A service-connected condition made a nonservice-connected dementia worse than its natural progress Needs medical evidence of the dementia's baseline severity, and only the increase beyond baseline and natural progress is service-connected
General principles 38 CFR 3.303; 3.310(d)(2) All the evidence, including evidence from service, shows the disease was incurred in service; or a TBI-related claim outside the presumption's limits is shown on the evidence, No presumption applies: VA decides it under its general principles of service connection, so the evidence has to show the link

If your veteran already has a service-connected TBI, note that cognitive impairment that is a residual of a service-connected TBI is evaluated under Diagnostic Code 8045 in 38 CFR 4.124a. If your veteran's service records show a head injury, those records are the place to start.

The TBI Rule: Which Dementias and Which Injuries

This is the closest thing VA has to a dementia presumption, and if your veteran had a serious head injury in service, it's the first rule to check. Under 38 CFR 3.310(d)(1), in a veteran with a service-connected TBI, three dementia types (presenile dementia of the Alzheimer type, frontotemporal dementia, and dementia with Lewy bodies) shall be held to be the proximate result of the service-connected TBI, in the absence of clear evidence to the contrary, if manifest within 15 years following moderate or severe TBI.

Notice that the rule says "presenile dementia of the Alzheimer type," not Alzheimer's disease in general, so ask the veteran's doctor to record the specific diagnosis in writing.

What "moderate or severe" means

VA classifies the TBI using a table in 38 CFR 3.310(d)(3).

Measure Mild Moderate Severe
Structural imaging Normal Normal or abnormal Normal or abnormal
Loss of consciousness 0 to 30 minutes More than 30 minutes and less than 24 hours More than 24 hours
Post-traumatic amnesia 0 to 1 day More than 1 and less than 7 days More than 7 days
Glasgow Coma Scale 13 to 15 9 to 12 3 to 8

A few easily missed details work in a veteran's favor:

  • The injury is judged as it was then: VA bases severity on the TBI symptoms at the time of injury or shortly thereafter, not on how your veteran functions today.
  • Not every criterion has to fit: VA won't require a TBI to meet all the criteria at a level to classify it there, and if it meets criteria in more than one category, VA ranks it at the highest level where a criterion is met, except where the qualifying criterion is the same at both levels.
  • Later statements can count too: in the 2013 rule that adopted the table, VA said contemporaneous evidence ordinarily will be the most probative evidence of the symptoms at the time of injury, but later statements may also be probative evidence VA must consider.

That last point matters when the injury happened decades ago. Records from the time ordinarily weigh most, but statements written later, including the veteran's own, may also be evidence VA must consider.

If the TBI was mild

Mild TBI is not covered by the dementia presumption, but that is not a bar. Under 38 CFR 3.310(d)(2), neither the severity levels nor the 15-year limit prevents service connection for a condition the evidence shows is proximately due to a service-connected TBI; VA decides that claim under its general principles of service connection. So the family brings the evidence instead: injury records from the time, plus medical evidence that the dementia is proximately due to the TBI.

If you've read that even mild head injuries raise dementia risk, VA weighed that when it left mild TBI out of the rule: its 2013 final rule said the studies the Institute of Medicine cited supported only "limited/suggestive" evidence linking mild TBI to dementia of the Alzheimer type, and only with loss of consciousness.

When a Service-Connected Condition Made Dementia Worse

Many families assume that if the dementia wasn't caused by service, there's nothing to claim. The aggravation rule in 38 CFR 3.310(b) asks a different question. In plain terms, the question isn't whether a service-connected condition caused the dementia, but whether it made the dementia worse than it would have become on its own.

This route carries a condition families should know before they file. VA will not concede aggravation unless the baseline level of severity of the dementia is established by medical evidence created before the onset of aggravation, or by the earliest medical evidence created at any time between the onset of aggravation and the receipt of medical evidence establishing the current level of severity.

Then VA does the math in a specific way. For an aggravation claim under 38 CFR 3.310(b), VA determines the dementia's baseline and current levels of severity under the Schedule for Rating Disabilities (38 CFR part 4) and measures the aggravation by deducting the baseline level of severity, as well as any increase due to the natural progress of the disease, from the current level. So only the extra worsening gets compensated, not the whole dementia.

It's hard to chase old records while managing a parent's daily care, but that baseline is why it's worth asking the doctors now for every note describing memory or thinking before things changed.

What Doesn't Qualify on Its Own

Two things families often hear about don't, by themselves, make dementia a VA disability.

Age-related dementia. Compensation is for disability resulting from injury or disease incurred in line of duty, or from a preexisting condition aggravated in line of duty, and a dementia that simply developed with age, with no link to service, doesn't meet that definition. Aggravation is the route to look at if a service-connected condition may have made it worse.

Agent Orange exposure. Alzheimer's disease and other dementias are not among the conditions VA presumes to be caused by Agent Orange exposure, so a veteran with age-related dementia generally cannot rely on that presumption. VA's Agent Orange page says a veteran with an illness that isn't on its presumptive list, who believes Agent Orange caused it, can still file a claim but will need to submit more evidence. The full presumptive list is in our guide to Agent Orange and PACT Act conditions.

How VA Rates Dementia

Under 38 CFR 4.126(c), neurocognitive disorders are evaluated under the General Rating Formula for Mental Disorders, and neurologic deficits or other impairments stemming from the same cause (a head injury, for example) are evaluated separately and combined with that rating. The mental-disorders schedule in 38 CFR 4.130 lists diagnostic codes including 9312 (major or mild neurocognitive disorder due to Alzheimer's disease), 9305 (major or mild vascular neurocognitive disorder), and 9304 (major or mild neurocognitive disorder due to traumatic brain injury).

Here's how the schedule describes each level. The symptoms after "such symptoms as" are examples from a longer list in the regulation, so read this as the schedule's text, not as a checklist you can score your parent against.

Rating What the schedule describes
100% Total occupational and social impairment, due to such symptoms as, among others, disorientation to time or place and memory loss for names of close relatives, own occupation, or own name
70% Occupational and social impairment, with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood, due to such symptoms as (among others listed) spatial disorientation and neglect of personal appearance and hygiene
50% Occupational and social impairment with reduced reliability and productivity due to such symptoms as (among others listed) difficulty in understanding complex commands, impairment of short- and long-term memory, impaired judgment, and impaired abstract thinking
30% Occupational and social impairment with occasional decrease in work efficiency and intermittent periods of inability to perform occupational tasks, due to such symptoms as (among others listed) mild memory loss, such as forgetting names, directions, recent events
10% Occupational and social impairment due to mild or transient symptoms which decrease work efficiency and ability to perform occupational tasks only during periods of significant stress, or symptoms controlled by continuous medication
0% A mental condition has been formally diagnosed, but symptoms are not severe enough either to interfere with occupational and social functioning or to require continuous medication

Be wary of anyone who promises a rating from a symptom list: only VA's rating decision, based on the medical evidence, sets the percentage. If your family disagrees with a decision, our guide to appealing a VA claim denial walks through how to ask VA to take another look.

What a Dementia Rating Can Open Up

An older veteran may already be rated for other conditions, and VA doesn't add ratings together. Under 38 CFR 4.25 it combines them using a table that considers the remaining efficiency after each disability, so 50 and 30 percent combine to 65, which becomes 70 percent. In 2026, a veteran with no dependents rated 100% receives $3,938.58 a month in basic compensation, under rates effective December 1, 2025. The full rate table, with dependent amounts, is in our VA disability compensation guide.

Can a Dementia Rating Lead to Special Monthly Compensation?

It can, and it matters most once service-connected dementia means your veteran needs someone's regular help just to get through the day. Special monthly compensation (SMC) is a higher rate of compensation for veterans with certain needs or disabilities, and for both levels below, the qualifying condition must result from service-connected disability.

Our SMC aid and attendance guide covers the eligibility details and compares SMC with the pension benefit called Aid and Attendance.

The caregiver stipend

A VA disability rating (individual or combined) of 70% or higher is one of the eligibility requirements for the Program of Comprehensive Assistance for Family Caregivers (PCAFC). For PCAFC, the dementia itself doesn't have to be service-connected: under the current rule, the veteran's need for personal care can come from a condition that isn't service-connected, as long as the 70% service-connected rating and the program's other requirements are met. If your veteran is already rated 70% for something else, read whether you can get the VA caregiver stipend for dementia before deciding what to file.

If VA Proposes That Your Veteran Can't Manage Benefits

This can feel like a blow when your veteran is still proud of handling his own checkbook. When dementia is in the medical record, VA may look at whether the veteran can manage benefits. Under 38 CFR 3.353, a mentally incompetent person is one who, because of injury or disease, lacks the mental capacity to contract or to manage his or her own affairs, including disbursement of funds without limitation. Where reasonable doubt arises, that doubt is resolved in favor of competency.

Your veteran has rights in this process:

  • Notice and a hearing: whenever VA proposes an incompetency determination, the veteran will be notified of the proposed action and of the right to a hearing, and a requested hearing must be held before the rating decision.
  • Time before a fiduciary is involved: VA waits 60 days after the decision letter before notifying the VA Fiduciary Program, which gives time to request a hearing or submit more evidence.
  • Review and restoration: a veteran who disagrees can request a decision review within 1 year of the date on the decision letter, and a veteran who believes they can manage benefits again can ask VA to review the case with a written request and supporting medical evidence.

Our guide to the VA fiduciary program covers what happens next, including how a fiduciary is chosen.

How to File a VA Disability Claim for Dementia

Doing it in order helps, and our guide to filing a VA disability claim for an aging parent covers the family side of the paperwork.

1
Step 1

Protect the effective date

An intent to file can secure the earliest possible effective date for any retroactive payments, and if VA receives the complete claim within 1 year, VA treats the claim as filed on the date it received the intent to file. See our guide to VA intent to file.

2
Step 2

Gather the injury records

For a TBI route, collect records from the time of the injury showing loss of consciousness, amnesia, or other symptoms, since VA judges TBI severity by the symptoms at the time of injury or shortly after. You don't have to chase federal records alone: VA's duty to assist includes getting the veteran's service medical records and other relevant federal records, as long as you give enough information to locate them.

3
Step 3

Gather the baseline records

For an aggravation claim, collect medical records describing the dementia before the worsening began, or the earliest records made after it began. For a private doctor or hospital, VA Form 21-4142 gives VA permission to request the records itself.

4
Step 4

Get the diagnosis in writing

Ask the treating doctor to name the specific type of dementia, since the TBI rule names three types.

5
Step 5

File VA Form 21-526EZ

VA's online 21-526EZ application is the one to use for a new or secondary condition or for increased compensation, and the evidence VA lists includes VA and private medical and hospital records. If dementia keeps your veteran from signing, a relative responsible for his care, a court-appointed representative, or an agent under a durable power of attorney can sign instead, certified on VA Form 21-0972.

6
Step 6

Ask for priority processing if your veteran qualifies

Once the claim exists, VA Form 20-10207 asks VA to decide it faster, and qualifying situations include being 85 or older or having a terminal illness.

If your veteran dies while the claim is pending, the claim doesn't simply end: a person who would be eligible for accrued benefits, such as a surviving spouse, can ask to be substituted as the claimant within one year of the death, so the claim is processed to completion. Our guide to VA survivor benefits (DIC) covers that deadline.

You don't have to do this alone, or pay to get started. VA accredits Veterans Service Organization representatives, claims agents, and attorneys, and VA-recognized VSO representatives help with claims free of charge. No one may charge a fee for preparing or filing an initial claim; accredited attorneys and agents may generally charge only after VA has decided the claim. You can find an accredited representative on VA's site.

Frequently Asked Questions

How does the VA rate dementia?

VA rates service-connected dementia as a neurocognitive disorder under the General Rating Formula for Mental Disorders in 38 CFR 4.130, at levels from 0 to 100 percent, with neurologic deficits from the same cause rated separately and combined. A rating isn't necessarily fixed for good, either. If a service-connected dementia gets worse, the veteran can file for increased compensation on the same VA Form 21-526EZ, with medical records showing the worsening. Our guide to asking VA for a higher rating when a condition gets worse covers that process.

Will my veteran need a VA exam?

Maybe. VA asks for a claim exam only when it needs more information, and if the file already holds enough medical evidence, VA can review the records instead through the Acceptable Clinical Evidence (ACE) process. To reschedule, tell VA or the exam contractor at least 48 hours ahead. Missing one without good cause has a cost: on an original compensation claim, VA rates it on the evidence it already has, and a claim for increase is denied. VA lists hospitalization and terminal illness among its examples of good cause, and its claim exam page explains how to tell VA the reason.

Is Alzheimer's service connected?

Not automatically. The TBI rule in 38 CFR 3.310(d) names "presenile dementia of the Alzheimer type" after a service-connected moderate or severe TBI, within 15 years. Outside that rule, Alzheimer's can still be service-connected on the evidence, as secondary to or aggravated by a service-connected condition.

Can dementia be service-connected without a head injury?

Yes, potentially. The secondary route covers any disability proximately due to a service-connected disease or injury, and the aggravation route covers a nonservice-connected dementia that a service-connected condition made worse, so neither requires a TBI.

What if VA denies the dementia claim?

VA offers three decision review options: a Supplemental Claim with new and relevant evidence VA didn't have before, a Higher-Level Review by a higher-level reviewer with no new evidence, or a Board Appeal to a Veterans Law Judge. For a Higher-Level Review or a Board Appeal, the deadline is one year from the date on the decision letter. New evidence for a dementia claim, such as a baseline medical record found after the decision, is what a Supplemental Claim is built to carry.
