Sleep Apnea, Lack of Deep Sleep Linked to Worse Brain Health

People who have sleep apnea and spend less time in deep sleep may be more likely to have brain biomarkers that have been linked to an increased risk of stroke, Alzheimer’s disease and cognitive decline, according to new research published in the May 10, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that these sleep disturbances cause the changes in the brain, or vice versa. It only shows an association.
