Alzheimer disease（ AD） is a kind of degenerative nervous system disease in elderly patients， with unclear mechanism and limited treatment. Drug therapy is limited by kinds of adverse reactions， so physiotherapy and cognitive intervention becomes a more acceptable treatment for patients. In recent years， some studies show that repetitive transcranial magnetic stimulation（ rTMS） can improve the cognitive function， behavior， and psychological symptoms of AD to some extent. Therefore， it is proposed to make a summary of the relevant progress here.
