Abstract
|
|
|
|
Paramedian thalamic stroke is known to be associated with hypersomnia, usually with bilateral lesions. We report a case of one patient who developed transient hypersomnia after unilateral paramedian thalamic infarction. A 79-year-old female patient with right paramedian thalamic infarction presented with left hemiparesis and hypersomnia. A night polysomnogram, 10 days after symptom onset, showed increased slow wave sleep and the presence of slow wave sleep throughout the entire night. Hypersomnia improved 7 weeks after the onset of symptom.
