Neurocognitive Disorder Due to Alzheimer Disease — VA Rating (DC 9312)
Diagnostic Code 9312 · 38 CFR §4.130
What Is It?
DC 9312 covers major or mild neurocognitive disorder due to Alzheimer disease. Alzheimer disease is a progressive neurodegenerative condition that causes worsening memory loss, confusion, difficulty with language and reasoning, personality changes, and eventually inability to care for oneself. For veterans, research has shown associations between traumatic brain injury, toxic exposures (particularly herbicide agents and burn pit emissions), and increased risk of Alzheimer disease. The VA rates this condition under the General Rating Formula for Mental Disorders at 38 CFR 4.130. Because the condition is progressive, veterans may need to file for increased ratings as symptoms worsen over time.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Total occupational and social impairment with severe cognitive decline, disorientation to time and place, inability to recognize family members, inability to perform activities of daily living, and need for full-time supervision or care. |
| 70% | Deficiencies in most areas due to significant cognitive decline. Memory loss affects daily activities, independent living requires assistance, judgment is impaired, and maintaining employment is no longer feasible. |
| 50% | Reduced reliability and productivity due to progressive memory loss, impaired judgment, difficulty following complex instructions, and increasing difficulty maintaining relationships and work performance. |
| 30% | Occasional decrease in work efficiency due to memory problems, word-finding difficulty, mild confusion, or difficulty with multi-step tasks. |
| 10% | Mild cognitive decline noticeable mainly during complex or stressful tasks, or managed with compensatory strategies and reminders. |
| 0% | Early diagnosis but cognitive symptoms do not yet impair occupational or social functioning. |
Evidence Needed
A diagnosis from a neurologist or psychiatrist is essential, typically supported by neuropsychological testing documenting progressive cognitive decline. Brain imaging (MRI showing hippocampal atrophy or PET scans) can support the diagnosis. Biomarker testing (cerebrospinal fluid analysis or amyloid PET) may be used in some cases. Medical records documenting the progression of symptoms over time are important. If claiming a connection to TBI or toxic exposure during service, documentation of those exposures and a nexus opinion are needed. Buddy statements from family describing the timeline and impact of cognitive decline are critical.
C&P Exam Tips
Describe the progression of cognitive symptoms in concrete terms: when you first noticed memory problems, how they have worsened, what you can no longer do that you used to manage. Specific examples carry more weight than general statements — if you get lost driving to familiar places, forget recent conversations entirely, or need help managing medications, describe those situations. If a family member accompanies you, their perspective is valuable because Alzheimer patients often underestimate their impairment. Describe the trajectory — the examiner needs to understand whether the condition is stable or progressing.
How to File
File on VA Form 21-526EZ with DC 9312. Submit neurological evaluations, neuropsychological testing, brain imaging, and all treatment records documenting the diagnosis and progression. If connecting to TBI, include the TBI documentation and a nexus opinion. If connecting to toxic exposure, submit deployment records and exposure documentation. Family involvement in the claims process is often essential given the cognitive impairment involved. A VSO experienced with serious neurological claims is strongly recommended.
Common Mistakes
Not filing until the condition is advanced is a common mistake — mild neurocognitive disorder due to Alzheimer disease is ratable, and filing early preserves the effective date. Another mistake is not connecting the condition to service. While Alzheimer disease is often considered age-related, growing research links it to TBI and toxic exposures, which many veterans experienced during service. Not having family involved in the claims process is risky because the veteran may lack the cognitive capacity to accurately report symptoms or navigate the system.
Frequently Asked Questions
Can Alzheimer disease be service-connected?
Yes. While Alzheimer disease is often associated with aging, it can be service-connected directly or secondary to service-connected conditions. Research has linked TBI and certain toxic exposures to increased Alzheimer risk. A nexus opinion from a neurologist connecting the condition to service is needed.
Should I file early or wait until symptoms are worse?
File as soon as you have a diagnosis, even if symptoms are mild. Filing early preserves your effective date, and you can request increased ratings as the condition progresses. Waiting means losing potential compensation for the period before you filed.
What if the veteran cannot manage their own claim?
Family members can help manage the claim process. If the veteran lacks capacity to manage their VA benefits, a fiduciary can be appointed. A VSO can assist throughout the process regardless of the veteran’s cognitive status.
