Description
Joy Zeynoun and co-authors study how a growth protein in the brain may change the link between sleep length and thinking, in a 2025 paper. Sleep helps the brain fix memories in place, and broken sleep patterns raise dementia risk. The protein, BDNF, supports that fixing process. The team asked whether people with more of the protein are shielded when their sleep runs long or short.
The sample held 2,344 adults from the Framingham Heart Study, drawn from three family cohorts. People reported how long they slept, and their thinking was scored from a set of standard tests. Sleeping nine hours or more went with worse overall scores than sleeping seven to eight. That harm showed up mainly in people with lower levels of the protein, while short sleep hurt only the higher group.
