Hallmarks of Alzheimer’s Found Well Before Diagnosis

A new study led by investigators at Massachusetts General Hospital shows that early accumulation of amyloid-β and tau protein begins to disrupt the brain’s connections important for memory years before signs of cognitive impairment were observed. The findings may lead to strategies that could help detect the condition early.
