In 5,774 adults followed for an average of 4.7 years, carrying two APOE ε4 alleles and female sex were linked to faster hippocampal shrinkage.In 5,774 adults followed for an average of 4.7 years, carrying two APOE ε4 alleles and female sex were linked to faster hippocampal shrinkage.
In two observational cohorts, genetic scores were linked to faster progression to Alzheimer’s disease, with hazard ratios, a measure of risk over time, of 1.25 to 2.02.In two observational cohorts, genetic scores were linked to faster progression to Alzheimer’s disease, with hazard ratios, a measure of risk over time, of 1.25 to 2.02.
