Alzheimer's disease (AD) is a chronic neurodegenerative disease that occurs insidiously and progresses over time. Its main symptoms include memory and language impairments. The pathogenesis of AD remains unclear,and drug treatment for AD is still unsatisfactory,pointing to the need for a new approach to treating this disease. Existing research has shown that repetitive transcranial magnetic stimulation (rTMS) can improve the cognitive and neuropsychiatric symptoms of patients with AD,which provides a new idea for the treatment of AD. Exploring the mechanism of rTMS improving the clinical manifestations of patients with AD can promote our understand of the pathogenesis of AD. This article summarized the pathological changes and clinical features of AD as well as research progress on rTMS in the treatment of AD,aiming to provide new ideas for studying the pathogenesis and treatment of AD.

N­methyl­D-aspartate （NMDA） receptors are ionotropic glutamate receptors that are widely expressed in the central nervous system.Through mediating Ca2+ influx for excitatory synaptic transmission，NMDA receptors play an important role in synaptic plasticity，learning，and memory.Migraine is a common primary headache that brings serious life and mental burdens to patients because of frequent attacks.The pathogenesis of migraine is still unclear.Glutamate and NMDA receptors have been demonstrated to be closely related to the occurrence of migraine.This paper reviews progress on the association of NMDA receptors with migraine and the use of NMDA receptor antagonists for the prevention and treatment of migraine，aiming to provide a reference for the pathogenesis and drug treatment of migraine.
