(A) Significant associations between lower EYO scores with later time of last morning awakening, longer sleep duration, and higher PC3-Hypersomnia score, adjusted for age and sex. (B) Lower EYO was observed in those with longer sleep duration (>8h) as compared to other sleep duration categories. Note that a lower EYO score includes negative values, representing dementia-free people older than their parent’s age at symptom onset. Betas are standardized. EYO, estimated years remaining to expected onset; PC3-Hypersomnia, third principal component of sleep characteristics representing a sleep pattern suggestive of hypersomnia.
