How Memantine works
Memantine protects brain cells by blocking excess glutamate, a chemical that overstimulates and harms neurons in Alzheimer’s disease. It attaches to N-methyl-D-aspartate (NMDA) receptors, like gates that control signal flow, and keeps them from staying open too long. This helps reduce brain noise while preserving normal learning and memory.
