An observational study of 39 older adults without cognitive impairment linked a measure of less complex nerve-cell branching to shorter, more fragmented sleep.An observational study of 39 older adults without cognitive impairment linked a measure of less complex nerve-cell branching to shorter, more fragmented sleep.

Who was studied39 cognitively unimpaired older adults
What changedSleep was shorter with less complex nerve-cell branching in the locus coeruleus
The catchSleep disruption could accelerate structural changes in the locus coeruleus, reversing the presumed direction
