Periodic limb movements in sleep (PLMS) is characterized by recurrent episodes of repetitive, stereotyped limb movements that occur during sleep. There have been a few reports on this condition developing after a stroke, but the movements in these reports were not prodromal stroke symptoms. We describe a case in which PLMS developed as a prodromal stroke symptom. A 78-year-old man experienced right hemiplegia and dysarthria following left striatocapsular infarct. After acute care, he was transferred to our center for rehabilitation. During rehabilitation, he complained of right-side involuntary leg movements during sleep. According to his history, it had been developed 10 days before the appearance of right hemiplegia. Polysomnography confirmed the diagnosis of PLMS. We propose that PLMS can be a prodromal stroke symptom resulting from a pyramidal tract lesion without involvement of sensory components.
