There’s still so much we don’t know about Alzheimer’s disease, but the link between poor sleep and worsening disease is one that researchers are exploring with gusto.

In a study published in 2023, scientists found that using sleeping pills to get some shut-eye could reduce the build-up of toxic clumps of proteins in fluid that washes the brain clean every night.

Researchers from Washington University in St. Louis found people who took suvorexant, a common treatment for insomnia, for two nights at a sleep clinic experienced a slight drop in two proteins, amyloid-beta and tau, that pile up in Alzheimer’s disease.
