People in early middle age who have poor sleep quality, including having difficulty falling or staying asleep, have more signs of poor brain health in late middle age, according to a new study. The study does not prove that poor sleep accelerates brain aging. It only shows an association between poor sleep quality and signs of brain aging.
People in early middle age who have poor sleep quality, including having difficulty falling or staying asleep, have more signs of poor brain health in late middle age, according to a study published in the October 23, 2024, online issue of, the medical journal of the American Academy of Neurology. The study does not prove that poor sleep accelerates brain aging. It only shows an association between poor sleep quality and signs of brain aging.
Researchers reviewed participants' responses to questions such as,"Do you usually have trouble falling asleep?""Do you usually wake up several times at night?" and"Do you usually wake up far too early?" They recorded the number of six poor sleep characteristics for each participant: short sleep duration, bad sleep quality, difficulty falling asleep, difficulty staying asleep, early morning awakening and daytime sleepiness.
After adjusting for factors such as age, sex, high blood pressure and diabetes, researchers found people in the middle group had an average brain age that was 1.6 years older than those in the low group, while those in the high group had an average brain age 2.6 years older. A limitation of the study was that participants reported their own sleep problems and it is possible they may not have reported them accurately.
