Epilepsy & seizure disorders

The VA recognizes epilepsy and seizure disorders as ratable conditions and evaluates them under its neurological rating rules in 38 CFR § 4.124a. The VA sorts seizures into two main types. A major (grand mal) seizure is a generalized convulsion with loss of consciousness. A minor (petit mal) seizure is a brief interruption in consciousness or conscious control — such as staring, rhythmic blinking, head nodding, or sudden jerking. Which type you have matters, because the VA uses different reference points for each.

Epilepsy is rated using the General Rating Formula for Major and Minor Epileptic Seizures. Diagnostic Code 8910 covers grand mal (rated on major seizures) and Diagnostic Code 8911 covers petit mal (rated on minor seizures). The rating generally scales with how often seizures happen over time — for example, the regulation lists 100% for averaging at least one major seizure per month over the last year, and steps down through 80%, 60%, 40%, and 20% as seizures become less frequent, with a 10% level for a confirmed diagnosis and a history of seizures. One note adds that if continuous medication is needed to control epilepsy, the minimum evaluation is 10%; another says that when both major and minor seizures are present, the VA rates the type that predominates.

These ratings rest on the seizures being documented, not just reported. Under 38 CFR § 4.121, to warrant a rating the seizures must be witnessed or verified at some time by a physician, though the VA may accept competent, consistent lay testimony about how often they occur. This is why medical records, witness statements, and a clear seizure history can all be part of a strong file.
