It is well established that the Apolipoprotein E (APOE) ε4 allele is associated with cognitive impairment and Alzheimer's disease in old age. By contrast, several studies have demonstrated cognitive benefits in young ε4 carriers. It is therefore possible that the ε4 allele exhibits a pleiotropic association with cognition across the life span where ε4-related benefits in youth reverse to become risk factors for cognitive impairment and dementia in later life. To date, though, there has been no broad quantitative review of work assessing APOE-cognition associations in children, adolescents and young adults.
