Abstract

Organic causes of astasia or asterixis have been described in the literature. However, concurrent unilateral manifestation of the two symptoms is extremely rare. We report two cases presenting with astasia and asterixis due to infarcts involving the ventrolateral nucleus of the left thalamus. Acute onset of astasia or asterixis in patients without significant metabolic disorder should alert the clinician on the possibility of acute stroke involving the thalamus. Key Words : Astasia, Asterixis, Thalamus, Infarct
