Limb-Shaking Transient Ischemic Attack Associated with Focal Electroencephalography Slowing: Case Report

Limb shaking is a rare form of transient ischemic attack (TIA) that can easily be confused with focal motor seizures. Case: We report a case of a 61-year-old man with rhythmic jerky movements of his left limb, without loss of awareness, that have occurred about once per month for the past four months, precipitated by standing up and extending the neck. The electroencephalography test showed right temporal slow activity, without epileptiform features. No evidence of a noteworthy structural lesion was found on magnetic resonance imaging of the brain. Doppler ultrasound and magnetic resonance angiography of the neck disclosed an 80% stenosis of the right internal carotid artery. The patient underwent an endarterectomy of the right internal carotid artery and remained asymptomatic in the 12-month follow-up period.
