Sleep came back for Alzheimer's patients in Beijing — a third better in 15 days, with no drug at all

For many people living with Alzheimer's, the nights are the hardest part — broken sleep, restlessness, and exhaustion by morning. Researchers at Xuanwu Hospital in Beijing tested a gentle, drug-free idea: mild electrical pulses delivered through small pads on the forehead and behind the ears, for an hour at a time. In a careful trial where half the patients received a look-alike treatment with no current, the treated group's sleep scores improved by about a third in just 15 days — from 9.65 to 6.35 on a standard sleep-quality scale — while the comparison group's scores barely moved. Nobody in either group had a serious side effect. The study was small — 43 patients finished it — and the researchers, publishing in the Journal of Alzheimer's Disease, are clear that bigger trials must confirm the result. But for families who know how much one good night changes the next day, a safe way to restore sleep without another pill is a hopeful direction.
