Although rare, MS seizures can occur when areas of the brain affected by multiple sclerosis begin to misfire. These brief electrical storms may cause sudden muscle jerks, loss of awareness, or unusual sensations such as flashing lights or a metallic taste. They can be frightening — but they’re also treatable and usually well controlled.
MS seizures result from demyelination in the cerebral cortex, disrupting the brain’s normal communication patterns. While fewer than 5 % of people with MS experience them, the possibility is real and worth understanding. Seizures may appear during relapses or periods of heightened inflammation, though many people never have one at all.
Managing MS seizures involves identifying triggers, maintaining good sleep and stress balance, and following any prescribed anti-seizure medication. Regular contact with a neurologist ensures both MS and seizure activity are monitored together.
Awareness brings reassurance. Knowing that seizures are part of the MS spectrum — not a separate diagnosis — helps replace fear with understanding, and understanding with control.
