Association Between Decline in Cognitive Processing Speed and CSF Amyloid‐β 42/40 in Cognitively Healthy Older Adults Aged 70, Followed over 5 to 7 Years: Data from the Gothenburg H70 Birth Cohort Study

Abstract

Background: Understanding early signs of cognitive decline in preclinical Alzheimer´s disease may open early intervention to slow down disease progression. We aimed to study the association between Amyloid‐β42/40 (Aβ) and cognitive decline, in a population‐based cohort of 70‐year‐olds followed over 5 to 7 years.
