Review the pathological involvement of cholinergic and glutamatergic neurotransmitter pathways in Alzheimer's disease and examine potential therapeutic synergies between cholinesterase inhibitors and memantine.
Narrative review synthesizing clinical and molecular evidence supporting the cholinergic and glutamatergic hypotheses of Alzheimer's disease.
Evaluation of mechanistic interactions between neurotransmitter cascades and the pharmacological rationale for combining memantine with cholinesterase inhibitors.
Cholinergic deficits involve reduced acetylcholine concentration, loss of functional cholinergic neurons, and decreased acetylcholinesterase activity.
Glutamatergic dysfunction causes neurotoxicity through sustained low-level overactivation of NMDA receptors, largely driven by defective astroglial glutamate reuptake in synaptic clefts.
Co-administering cholinesterase inhibitors with the NMDA receptor antagonist memantine demonstrates potential synergy for mitigating neurological and cognitive impairment.
