Stem cells in the treatment of neurodegenerative diseases (3)

Existing drugs for the treatment of Alzheimer's disease only allow you to stop the symptoms of the disease. The use of stem cells is one of the promising directions for the development of pathogenetic and etiotropic methods of treatment of this most common form of senile dementia.
