title: [Concentrations of multiple neurochemicals in the cerebrospinal fluid of patients with senile dementia and the relationship to alpha 1-antichymotrypsin].
abstract: The authors investigated the concentrations of multiple neurochemicals (6 kinds of catecholaminergic and 5 kinds of indolaminergic substances) in the lumbar cerebrospinal fluid (CSF) of patients with and without senile dementia (13 Alzheimer type (AD), 7 vascular type (VD), 11 Parkinson's disease (PD) and 9 non-demented controls (C)) by means of a neurochemical analyzing system (Neurochem, ESA). By means of the enzyme-linked immunosorbent assay (ELISA), we also determined the concentration of alpha 1-antichymotrypsin (ACT) in the CSF, which may be a possible diagnostic biochemical marker of the senile dementia of Alzheimer type. ACT in CSF was significantly higher in the AD group. It correlated negatively with Hasegawa's dementia scale (HDS) significantly. It also correlated negatively with the concentration of HVA significantly and showed tendency to correlate with the concentrations of dopamine and the ratio of kynurenine and tryptophan (KYN/TRP). Each dementia group showed characteristic concentration patterns of neurochemicals (DA, HVA, MHPG/NE, KYN/TRP, and 5-HIAA/5-HT). Our approach may provide a new quantitative method to diagnose geriatric neuropsychological diseases as well as senile dementia.
