Jacksonian seizure as the relapse symptom of multiple sclerosis

Abstract

• Epilepsy is more common in patients with multiple sclerosis (MS) than in the general population, occurring in 2%–3% of patients. Convulsions may be either tonic–clonic in nature or partial complex. In these individuals, seizures most likely result from lesions present in the cerebral cortex and subcortical white matter. A Jacksonian seizure is a type of simple partial seizure characterized by abnormal movements that begin in one group of muscles and progress to adjacent groups of muscles. We describe a case of Jacksonian seizure as the relapse symptom of MS. Focal motor seizures of this patient have been observed before and presumably marking the clinical onset or during acute bouts of MS. In this case, Jacksonian seizures appear to be the sign of a flare of MS, while the majority of seizures had been reported occur unrelated to MS relapses.
