It is supposed that Alzheimer’s disease occurs as a result of excessive stimulation of nerve cells by the main excitatory neurotransmitter present inside the brain. Excess stimulation of nerve cells can lead to the degeneration of nerves. The nerve cells in the brain produce and releases the neurotransmitter glutamate. This glutamate then moves to nearby nerve cells where it binds to a receptor N-methyl-D-aspartate (NMDA), present on the surface of the cells. Memantine blocks the NMDA receptor and thus reduces the effects of glutamate. It is believed that memantine can protect nerve cells from excess stimulation by glutamate by blocking the NMDA receptor and the effects of glutamate.
