New study hints at a hidden Alzheimer’s risk factor affecting older Americans

People with greater vulnerability to aerial contamination could look a higher hazard of processing Alzheimer's disease, according to a caller survey by Emory University successful Atlanta.

Air contamination has antecedently been established arsenic a hazard origin for Alzheimer’s, arsenic good arsenic different chronic conditions, similar hypertension, changeable and depression, the researchers noted.
