ChEIs are believed to target cholinergic abnormalities in Alzheimer's disease, although there is evidence indicating that their therapeutic effect may be via the glutamatergic system. NMDA receptor antagonists, in contrast, are believed to target the glutamatergic system directly PubMed:16273023

There are no cures for any tauopathy. Neuroprotective agents, such as acetylcholinesterase inhibitors and NMDA antagonists, have been approved for use in the clinic, based on their ability to slow the rate of cognitive decline in patients with moderate to severe AD (reviewed in [36]) PubMed:21882945

With regard to the glutamatergic system, studies suggest that ChEIs may stimulate the release of glutamate from pyramidal neurons during normal neuronal activity, while NMDA receptor antagonists are believed to block the abnormal neuronal activity that results from the presence of excess glutamate in the synapse under resting conditions. Thus, ChEIs and NMDA receptor antagonists appear to have complementary effects, as the former enhance the signals received by postsynaptic neurons during normal neurotransmission, and the latter diminish the background 'noise' that is constantly being detected by those same receptors.
