Diagnostic Code 9312 · 38 CFR §4.130
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 |
|---|---|
| 0% | Early diagnosis but cognitive symptoms do not yet impair occupational or social functioning. |
| 10% | Mild cognitive decline noticeable mainly during complex or stressful tasks, or managed with compensatory strategies and reminders. |
| 30% | Occasional decrease in work efficiency due to memory problems, word-finding difficulty, mild confusion, or difficulty with multi-step tasks. |
| 50% | Reduced reliability and productivity due to progressive memory loss, impaired judgment, difficulty following complex instructions, and increasing difficulty maintaining relationships and work performance. |
| 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. |
| 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. |
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.
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.
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.
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.
