Wake-Up Sleepyhead: Unilateral Diencephalic Stroke Presenting With Excessive Sleepiness

Wake-Up Sleepyhead: Unilateral Diencephalic Stroke Presenting With Excessive Sleepiness

R Pradeep et al. J Neurosci Rural Pract.


Altered sleep architecture and stroke share a reciprocal relationship. More than half of the stroke patients display sleep abnormalities including hypersomnia, insomnia, parasomnia, periodic limb movements, or sleep-disordered breathing. Conversely, one of the major causes of severe organic hypersomnia is acute brainstem strokes, involving thalamic infarctions, which may be reversible over 6-12 months. Here, we report a patient with increased lethargy and drowsiness who was diagnosed to have a right thalamic and hypothalamic ischemic stroke.

Keywords: Drowsiness with stroke; paramedian thalamic stroke; thalamic infarction; thalamic stroke.

Conflict of interest statement
