Sleep apnea during REM sleep linked to memory-related brain changes (sciencedaily.com)
Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a study published May 7, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.

Targeting Brain's Drainage Pathways Rejuvenates Memory (neurosciencenews.com)
Now, researchers at Washington University School of Medicine in St. Louis report they have found a way around that problem by targeting the network of vessels that drain waste from the brain. Rejuvenating those vessels, they have shown, improves memory in old mice.

Review: Evidence expanding that 40Hz gamma stimulation promotes brain health (picower.mit.edu)
A decade after scientists in The Picower Institute for Learning and Memory at MIT first began testing whether sensory stimulation of the brain’s 40Hz “gamma” frequency rhythms could treat Alzheimer’s disease in mice, a growing evidence base supporting the idea that it can improve brain health—in humans as well as animals—has emerged from the work of labs all over the world.

How human brains got so big: cells learned to handle stress that comes with size (nature.com)
Humans have evolved disproportionately large brains compared with our primate relatives — but this neurological upgrade came at a cost. Scientists exploring the trade-off have discovered unique genetic features that show how human brain cells handle the stress of keeping a big brain working. The work could inspire new lines of research to understand conditions such as Parkinson’s disease and schizophrenia.
