§ 4.124a Schedule of ratings—neurological conditions and convulsive disorders.

Grand mal seizures

A type of seizure involving loss of consciousness and convulsions affecting the entire body.

What the rating means

Grand mal epilepsy is rated under the General Rating Formula for Major Epileptic Seizures. The possible ratings are 10%, 20%, 40%, 60%, 80%, and 100%, based on how often your major seizures occur over a set period of time.

A confirmed diagnosis of epilepsy with a history of seizures earns a 10% rating. The rating rises with seizure frequency: at least one major seizure in the last two years supports a 20% rating, while at least one in the last six months — or two in the last year — supports 40%. Averaging at least one major seizure every four months over the last year supports 60%, and averaging at least one every three months supports 80%. Averaging at least one major seizure per month over the last year supports 100%.

Two notes shape how these criteria are applied. If you take continuous medication to control your epilepsy, the minimum rating is 10%, and that rating cannot be combined with any other epilepsy rating. There is no distinction between seizures that occur during the day and those that occur at night; both count the same way.

Evidence that helps

The most important evidence for this condition is a documented record of seizure frequency over time. Medical records that log each seizure event — including the date, duration, and nature of the episode — directly support the frequency counts the rating criteria require. Neurologist notes, emergency room visits, and hospitalizations related to seizures all contribute to that picture.

A formal diagnosis of epilepsy confirmed by a treating provider, along with any electroencephalogram (EEG) results, supports the baseline 10% rating level. Records showing that a physician has prescribed continuous medication to control your seizures are also relevant, since that finding sets a minimum 10% evaluation regardless of current seizure frequency.

Statements from people who have witnessed your seizures — family members, caregivers, or coworkers — can help establish how often seizures occur, especially when a seizure happens outside a clinical setting and is not recorded in medical files. Your own statements describing the frequency, timing, and impact of seizures on your work and daily life add context to the clinical record.

Secondary conditions

Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
