Diagnostic Code 8912 · 38 CFR §4.124a
Jacksonian epilepsy (also called Jacksonian march) is a type of focal motor seizure that begins with twitching or jerking in one specific body part — typically a hand, foot, or one side of the face — and then progressively spreads to involve more of that side of the body. The seizure marches along the body following the mapped organization of the motor cortex. Veterans commonly develop this type of seizure from traumatic brain injuries with focal cortical damage, brain surgery scars, or shrapnel injuries to specific areas of the brain. The focal nature of these seizures points to a specific area of brain damage.
