A community-based, longitudinal study published in the July issue of SLEEP reports that short sleep duration is associated with greater age-related brain atrophy in the subsequent two years. Among relatively healthy, ethnically Chinese older adults in Singapore, self-reported short sleep duration at baseline was associated with faster ventricular expansion, which is a reliable marker for risk of cognitive impairment. Global sleep quality at baseline did not influence any of the variables of interest.
