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

Jacksonian and focal seizures

Seizures that begin in one area of the brain and may cause localized muscle movements or sensory changes.

What the rating means

Jacksonian and focal motor or sensory epilepsy is rated under the General Rating Formula for Major and Minor Epileptic Seizures. The ratings are 10%, 20%, 40%, 60%, 80%, and 100%, depending on how often you have seizures and whether they are major or minor. A confirmed diagnosis with a history of seizures earns 10%. From there, the rating rises with seizure frequency: at least one major seizure in the last two years, or at least two minor seizures in the last six months, rates 20%. At least one major seizure in the last six months or two in the last year, or averaging five to eight minor seizures weekly, rates 40%. Higher frequencies step up to 60%, 80%, and 100%. When both major and minor seizures are present, VA rates only the predominating type. There is no distinction between daytime and nighttime major seizures. If continuous medication is shown necessary to control the epilepsy, the minimum rating is 10%, and that rating cannot be combined with any other epilepsy rating.

Evidence that helps

Medical records documenting a confirmed diagnosis of epilepsy are the foundation of any rating. To support a higher rating, records should clearly show how often seizures occur. Neurology notes, emergency room visits, and treatment records that log individual seizure events over time are directly relevant, because the criteria measure frequency across specific windows — such as the past six months or the past one to two years. EEG results and imaging that confirm the diagnosis also help establish the condition. Seizure logs or diaries you or a caregiver keep can supplement clinical records by capturing events that did not result in a medical visit. Statements from people who have witnessed your seizures can help describe their character and frequency. Records showing that continuous medication is prescribed to control your seizures support at least the 10% minimum. Because the rating turns on documented frequency, thorough and consistent medical follow-up over time creates the clearest picture of where your seizures fall within the formula.

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.
