Pharmacologic modelling of Alzheimer's disease.
Evidence pointing to the central role of the cholinergic system in normal human memory function and disorders such as Alzheimer's disease has grown tremendously in recent years. Anticholinergic and non-cholinergic agents have been found to create transient memory impairments in young adults which mimic the changes associated with normal aging or amnesia. The rationale for using scopolamine, a centrally active anticholinergic agent, as a pharmacologic probe of memory function is reviewed using data from studies in animals and humans. The cognitive functioning of normal elderly controls given scopolamine is compared to the baseline functioning of patients with Alzheimer's disease, followed by a discussion of the use of scopolamine as a modelling agent for dementia.
