The article discusses the study of the occurrence of homovanillic acid (HVA) in the human brain, with regard to senile dementia. Senile dementia is a disease with a disturbance in the monoamine metabolism, which is reflected in a reduction of HVA in the neostriatum. The study was conducted to a control group and three dementia groups on the concentration of HVA in the caudate nucleus, the putamen, and the globus pallidus. Findings show that in a presumed senile dementia group there is a significantly lower concentration of HVA compared with the other groups. In addition, the relation between HVA concentration and degree of dementia in the senile dementia group is statistically significant.
