Abstract
Alzheimer's disease (AD) is a type of degenerative disease that primarily affects in the central nervous system of elderly or pre-elderly individuals. The symptoms of Alzheimer's disease include memory impairment, aphasia, loss of function, dementia, and impairment of visual spatial ability, which in turn affects the physical health of patients. Mesenchymal stem cell therapy is a branch of regenerative medicine that primarily utilizes stem cells or their derivatives to stimulate the body's own healing process and repair damaged, diseased, or injured tissues. Its utilization in the treatment of autoimmune diseases and neurological disorders has been extensively documented. This review summarizes the preclinical and clinical applications of mesenchymal stem cells in AD, their underlying mechanisms and the application limitations of their application and potential solutions. It is hoped that researchers in this field will find it a useful foundation for further study of mesenchymal stem cell therapy.
