Symptom Detail



Seizures have long been recognized to be part of the disease spectrum of MS). While they occur in only a minority of patients with MS, epileptic seizures can have serious consequences.


A seizure is defined as a transient symptom of abnormal excessive or synchronous neuronal activity in the brain. The outward effect can be as dramatic as a wild thrashing movement or as mild as a brief loss of awareness. Sometimes it is accompanied by a full body \\\”slump\\\”, where the person simply will lose control of their body and slump to the ground. It can also manifest as an alteration in mental state.

Important Facts

The cause of seizures in people with multiple sclerosis isn’t completely understood. In these individuals, seizures most likely result from lesions present in the cerebral cortex and adjacent white matter. However, other factors may play a role — especially since such lesions are very common and seizures are unusual in multiple sclerosis.


Seizures are the result of abnormal electrical discharges in an injured or scarred area of the brain.


Seizures are diagnosed by clinical history and an electroencephalogram (EEG) and then treated by an appropriate anticonvulsant medication such as Carbamazepine or Phenytoin.
