APOE ε4, the strongest genetic risk factor for late-onset Alzheimer's disease, has been associated with sleep disturbances such as fragmented sleep, reduced sleep efficiency, and altered circadian rhythms. Some studies report that ε4 carriers have less slow-wave sleep and more nighttime awakenings. However, effect sizes are small, study populations are heterogeneous (different ages, sleep measurement methods), and causality is unclear – sleep problems may be an early symptom of neurodegeneration rather than a direct genetic effect. No robust randomized trials demonstrate that APOE genotype directly modifies sleep in healthy individuals. Consumer DNA tests that include APOE provide risk estimates, not diagnoses. A common myth is that APOE ε4 guarantees poor sleep; in reality, many ε4 carriers sleep normally. Another myth is that improving sleep can eliminate Alzheimer's risk – evidence for this is weak. The fact is that APOE likely influences sleep via lipid metabolism and neuroinflammation, but individual predictive power is low. Be cautious of marketing claims that overstate this link.
