Food and Drug Administration attempts to augment cholinergic neurotransmission by blocking acetylcholinesterase. Selective muscarinic and nicotinic agonists are also in development. So far, results with the muscarinic agents have been disappointing, and nicotinic agents are still in early clinical trials (Decker and Brioni 1997; Jaen and Schwarz 1997). The short-term clinical effects of cholinergic augmentation have generally been modest, possibly because of the extensive damage already suffered by the cholinergic system at the time of diagnosis, the significant age-associated decline in the uptake of circulating choline into the brain, and the possible activity of the cholinergic receptor systems.

Excitatory Amino Acids Glutamate is the dominant excitatory neurotransmitter in the brain. Data indicate that whereas patients with AD have a fairly severe loss of cortical, hippocampal, and striatal glutamate (Gsell et al. 1997), patients who are in the advanced stages of AD have elevated concentrations of cerebrospinal fluid glutamate and aspartate. Glutamate exerts its effects through four classes of receptors: NMDA (N-methyl-D-aspartate), AMPA (a-amino-3hydroxy-5-methyl-4-isoxazole proprionic acid), kainate, and metabotropic receptors.
