Association of a salivary acetylcholinesterase with Alzheimer's disease and response to cholinesterase inhibitors.
OBJECTIVES: A decrease in cholinergic activity is a key event in the biochemistry of Alzheimer's disease (AD). The aim of the study was to investigate the expression levels of markers of cholinergic function in saliva, which is a readily accessible body fluid that can be obtained from subjects with minimal distress. DESIGN AND METHODS: Salivary samples were obtained from people with NINCDS-ARDRA "probable" Alzheimer's disease and age- and sex-matched controls. Salivary acetylcholinesterase enzyme (AChE) activity was determined colorometrically. RESULTS: Robust AChE catalytic activity was detected in the saliva samples that was stable for up to 6 h at room temperature following the provision of the salivary sample. The activity of the enzyme was significantly lower in people with AD than in age-matched controls. In addition, there were significant differences in activity between those who responded to acetylcholinesterase inhibitor (AChE-I) therapy and those who did not. CONCLUSIONS: Salivary enzyme activity may therefore prove to be a useful marker of central cholinergic activity.
