Emotion control and cerebellar atrophy in senile dementia.
New research increasingly indicates that the cerebellum coordinates and integrates a wide range of processes not confined to the motor sphere. Since satisfying correlations between affective disturbances and signs of cerebral atrophy have not been found, the relationship of CT-indicated cerebellar atrophy to certain psychopathologic indicators, in patients suffering from senile dementia, has been studied. The patients participating in the study were 21 women and 18 men with a mean age of 69.4 years. Each patient showed a definite pathologic score in at least one cerebral CT-measurement. The Spearman rank correlations between affective incontinency, lability of affect, and cerebellar atrophy suggest substantial relationships between affective symptoms and cerebellar pathology. This seems all the more remarkable since all of the various indicators of cerebral cortical and subcortical atrophy lacked to show any strong relationship to affective symptoms at all. The implications of the findings for research and clinical purposes are discussed.
