the failure of clinical trials is attributable, at least in part, to testing of potential disease-modifying therapeutic agents too late in the pathophysiological course of AD. Thus, a possible strategy to achieve success is earlier intervention. Data from both genetic at-risk and biomarker at-risk cohorts support implementation of such a strategy.

From a genetic perspective, Alzheimer s disease can be subdivided into a rare familial form, which accounts for less than 1% of all patients and typically presents with

It is possible for an individual to develop Alzheimer disease without having the common variant in APOE, and many individuals with the variant will never develop the condition. Because of this limitation of genetic testing for Alzheimer disease, family history is a vital component to assess an individual s risk.

Clear evidence of decline in memory and learning and at least one other cognitive domain (based on detailed history or serial neuropsychological testing). 2.

Jan 23, 2021 Introduction Alzheimer s disease (AD) is a highly disabling neurodegenerative disease characterized by memory loss and a gradual cognitive, functional and behavioral decline (1). Its prevalence increases rapidly with age, affecting 13% of population at age 80, and 37% of the population at age 90 (2).

Background: In recent years, researchers have increasingly employed genetic testing as a means for understanding and treating diseases like Alzheimer disease, a common progressive disease affecting cognition and behavior. Genetic studies hold the potential for major breakthroughs in treatment of diseases like Alzheimer disease.
