Normal sleep architecture and arousal require an intact thalamus. Thalamic vascular lesions, particularly in the paramedian region may cause arousal disturbances and hypersomnolence. Although hypersomnolence is one of the main characteristics of acute bilateral paramedian thalamic infarcts, there are only scarce reports in literature concerning polysomnographic follow-up of these patients. The few reported cases in literature show that sleep stages do not significantly change from the acute to chronic phase.We present a case report of a patient with a bilateral paramedian thalamic infarct in which a polysomnographic evaluation of sleep was performed four days and five months after stroke.
