 Alzheimer's disease, AD, is caused by multiple genetic, metabolic, and environmental factors. These factors can lead to changes in the brain cells such as astrocytes, oligodendrocytes, neurons, endothelial cells, slash parasites, and microglia. Several drugs have been identified that can target these specific cell types and potentially reverse the effects of AD. These drugs include clemestine, dantraline, erythropoietin, fengolimod, fluoxetine, lithium, mementine, minocycline, pyaglitazone, paracetam, and rilazole. By combining two or three of these drugs, it may be possible to reverse the effects of AD.
