Unilateral periodic limb movement in sleep after supratentorial cerebral infarction.
We report a patient with involuntary right leg movements during sleep, which developed after acute ischemic stroke in the corona radiata. Nocturnal polysomnography confirmed the diagnosis of periodic limb movement in sleep (PLMS). Although the pathogenesis of PLMS is still controversial, it has been proposed that the loss of cortical or subcortical inhibition resulting from the pyramidal tract lesion might cause PLMS. The present case provides evidence to support this hypothesis.
