Unfortunately, no such drugs exist today. Medications are used to treat patient with Alzheimer’s disease and other dementias, but their action is strictly symptomatic and very modest at that. These drugs target various neurotransmitter systems in the brain and tend to have a very modest and transient therapeutic effect on cognition. Most of these drugs target the cholineric or glutaminergic neurotransmitter systems in the brain, by stimulating the former or dampening the latter. But there is a lot of effort underway to develop more effective pharmacology for Alzheimer’s disease and one may expectgoodlong-term progress is their development.
