Are spinal seizures and myoclonic jerks in the arms and legs common in MS patients?

Seizures, including myoclonic jerks (sudden, involuntary muscle twitches), do occur more frequently in people with MS than in the general population. Around 2%–5% of people with MS experience epilepsy, and up to 8 in 100 people with MS may experience seizures overall.

MS-related brain lesions can disrupt normal neuron connections, which can trigger seizures. Jerking in the arms and legs can be one way this shows up. It's also worth knowing that not every jerking movement is a seizure. In MS, there are conditions that can look like seizures but aren't, including:

- Spasticity – involuntary muscle stiffness or spasms
- Lhermitte's Sign – electric shock-like sensations, often triggered by bending the neck
- Choreoathetosis – "dance-like" involuntary limb movements caused by lesions in deeper brain structures

A MyMSTeam member shared: *"My right leg kicks out without warning"* — a reminder that these experiences are very real and relatable.

Since this is happening daily, it's really important to speak with a neurologist. They may recommend an MRI or EEG to pinpoint what's going on and find the right treatment, which could include antiepileptic drugs (AEDs) or other options depending on the cause.
