The cerebellum may be directly involved in cognitive functions

Neuropsychological deficits may occur in infratentorial strokes. Only minor cognitive disturbances are reported in unilateral anterior cerebellar lesions. Here, the authors describe a patient with bilateral anterior ponto-cerebellar ischemic lesions associated with major neuropsychological deficits. Cerebral PET and SPECT demonstrated no metabolic defect in supratentorial areas.
