Claim Raven explanation
What this means
This section addresses verification of epilepsy and evidence of seizure frequency. It requires seizures to have been witnessed or verified at some time by a physician and discusses further observation when the nature of the attacks is uncertain.
Competent, consistent personal observations may be accepted for frequency when they describe the event and immediate after-effects. The frequency should reflect ordinary life, rather than only a period of hospitalization.
How this helps your claim
This helps you understand why clinical verification and a clear event history serve different purposes. Record what witnesses actually observed without asking them to make a medical diagnosis.
What to check in your records
Use your decision, examination reports, and relevant records to check the following points.
- Locate the physician's verification or diagnosis of seizures.
- Review consistent dated descriptions of attacks and immediate after-effects.
- Compare the frequency used in the decision with the ordinary-life history.
Record the events without guessing their medical classification
A witness account can describe what happened before, during and immediately after an episode, including duration and observed behavior. That is different from a layperson diagnosing the event. Keep the physician's verification and the observations in their proper roles.
For frequency, use a consistent dated record of actual events during ordinary life. Include uncertainty about unwitnessed episodes rather than turning an estimate into a definite count. An unusually intensive period of hospital observation may not describe the same pattern as daily life outside the hospital.
Can family observations help establish seizure frequency?
The regulation allows competent, consistent observations for that purpose when the events and immediate after-effects are described adequately. Those observations do not replace the medical verification requirement. Clear factual descriptions are more useful than assigning seizure categories that the witness is not qualified to diagnose.

§ 4.121 Identification of epilepsy.
When there is doubt as to the true nature of epileptiform attacks, neurological observation in a hospital adequate to make such a study is necessary. To warrant a rating for epilepsy, the seizures must be witnessed or verified at some time by a physician. As to frequency, competent, consistent lay testimony emphasizing convulsive and immediate post-convulsive characteristics may be accepted. The frequency of seizures should be ascertained under the ordinary conditions of life (while not hospitalized).
