Seizure Disorder VA Disability Rating
DC 8910 | 38 C.F.R. § 4.124a | M21-1, Part IV.ii.4.F
OVERVIEW
Seizure disorders are rated under DC 8910 (grand mal) at 38 C.F.R. § 4.124a using the General Rating Formula for Major and Minor Epileptic Seizures. Rating is based on average seizure frequency over the past year. Veterans commonly develop seizure disorders from TBI, head trauma, or as secondary to service-connected conditions. A major seizure is a generalized tonic-clonic convulsion with unconsciousness.
RATING CRITERIA (6 LEVELS)
100% — Averaging at least 1 major seizure per month
Averaging at least 1 major seizure per month over the last year.
80% — 1 major seizure in 3 months, or >10 minor seizures weekly
Averaging at least 1 major seizure in 3 months over the last year; OR more than 10 minor seizures weekly.
60% — 1 major seizure in 4 months, or 9-10 minor seizures weekly
Averaging at least 1 major seizure in 4 months; OR 9-10 minor seizures per week.
40% — 1 major seizure in 6 months, or 5-8 minor seizures weekly
At least 1 major seizure in last 6 months or 2 in last year; OR averaging 5-8 minor seizures weekly.
20% — 1 major seizure in 2 years, or 2 minor seizures in 6 months
At least 1 major seizure in the last 2 years; OR at least 2 minor seizures in the last 6 months.
10% — Confirmed diagnosis with history of seizures
Confirmed diagnosis with a history of seizures. Minimum 10% when on continuous medication.
KEY EVIDENCE TO GATHER
-EEG confirming epileptiform activity
-Neurology evaluation documenting seizure type, frequency, and medication
-Emergency department records for seizure episodes
-Witness accounts describing seizure characteristics
-Records of antiepileptic medications
-Service records documenting head trauma, blast exposure, or TBI
SECONDARY CONDITIONS (3 MAPPED)
DC 9434
Epilepsy causes significant depression — anti-epileptic medications also contribute.
DC 9304/9326
Chronic seizure activity and antiepileptic medication cause cognitive impairment.
DC 7039
Nocturnal seizures severely disrupt sleep — rate separately.
C&P EXAM TIPS (5)
1.Keep a seizure diary documenting each event — date, time, duration, type. Primary evidence for frequency ratings.
2.Continuous antiepileptic medication alone supports 10% minimum rating.
3.Seizures controlled by medication are still ratable — 'well-controlled' does not mean 0%.
4.Seizures secondary to service-connected TBI are frequently service-connected.
5.Witness statements describing seizures are valuable evidence when the veteran cannot remember the event.
RELEVANT CASE LAW
38 C.F.R. § 4.124a, DC 8910 Note
When continuous medication is shown necessary for control, 10% evaluation assigned even with no additional seizures. Rating based on average frequency over the last year.
DOLLAR IMPACT
Minimum 10% with controlled seizures: $175.03/mo. Monthly major seizures: 100% = $3,938.58/mo. Seizures secondary to service-connected TBI add significant combined rating points.
