Recent authors reported a cerebellar contribution to cognitive functions such as executive function, personality, spatial cognition, language and memory. Middleton and Strick showed the neuroanatomical projection from the dentate nucleus to dorsolateral prefrontal cortex. Patients with cerebellar diseases were reported to have cognitive impairment in their neuropsychological assessments. The present patient with cerebellar hemorrhage showed disorder of executive function and memory disorder in his neuropsy-chological assessments. In his daily living, we found him to exhibit a distractible affection and disinhibition, which often disrupted the rehabilitation processes. A brain MRI showed no lesions in the bilateral frontal areas but SPECT showed a lower blood flow there. To approach these cases, we should recognize the existence of impaired higher brain function, and not only be mindful of motor deficits.
