CLINICAL OBSERVATIONS OF IMPAIRED CRANIAL NERVE FUNCTION IN SENILE DEMENTIA

A study was made of the cranial nerve functions in 66 women with a well-verified diagnosis of senile dementia (mean age 79). The study included a preliminary investigation and also a longitudinal study for a period of 3 years. The study was part of a larger research project including psychiatric, psychometric, neuro-physiologic, cerebral-circulatory, biochemical and neuropathologic co-ordinated studies. The diagnoses in all the patients were later followed up at the autopsies. The clinical investigations were also carried out on 50 control cases. The results showed a marked functional impairment of certain cranial nerves in senile dementia (particularly olfactory and gustatory nerves), which occurred relatively early in the disease and progressed with the course of the disease. No similar systematic study of these phenomena seems to have been carried out. The present investigation comprises primary observations which provide an important addition to the clinical picture of senile dementia, not hitherto described in the literature. The patients differed markedly from the control group where only mild impairment of cranial nerve function occurred and no progression could be demonstrated.
