It has been observed since long that the cases of cerebellar hemorrhage often had the difficulty of rehabilitation not only by a truncal ataxia but also by a retarded intelligence, a loss of volition and a decreased attention span. The authors investigated 7 cases of operated cerebellar hemorrhage of moderate size on how they were disturbed on the higher cerebral functions by applying them WAIS and other several neuropsychological test batteries. The frontal lobe functions were examined by the original test batteries of our design.
As the results, there was the moderate or severe decrease of WAIS on all 7 cases and also marked disturbance of the frontal lobe functions on 4 cases excluding 3 unapplicable cases.
The above results will suggest anyhow that the cerebellar damage around the dentate nucleus would give rise the disturbance of generalized higher cerebral functions, though its mechanism has not not been elucidated.
It would be very important for us now on to examine extensive higher cerebral function on those cases of cerebellar hemorrhage.
