Researchers have discovered a new drug which may protect against memory loss nerve damage and other symptoms of Alzheimer's disease. Preclinical research published in the Journal of Pharmacology and Experimental Therapeutics found that the drug -- called BPN14770 -- deters the effects of amyloid beta a hallmark protein of Alzheimer's that is toxic to nerve cells. BPN14770 under development by Tetra Therapeutics could help activate these mechanisms that support nerve health and prevent dementia even with the progression of Alzheimer's. Such observations imply that Alzheimer's pathology can be tolerated by the brain to some extent due to compensatory mechanisms operating
