Choline Acetyltransferase and Substance P Level in Alzheimer’s Disease and Multi-Infarct Dementia
Neurochemical studies on dementia of Alzheimer type (SDAT) have indicated changes not only in the cholinergic system but also an involvement of other transmitters such as those of the noradrenergic, dopaminergic, and serotonergic systems. For substance P the results have not been consistent, though both decreased and unchanged levels of substance P have been reported. The purpose of this study was to measure substance P-like immunoreactivity and choline acetyltransferase activity in brains from SDAT patients and from patients with multi-infarct dementia (MID).
