![]() To fully explore the relationship between sleep problems and biomarkers and the impact of sleep quality improvement or sleep apnea treatment, future research is needed. This study is potentially limited in representing full sleep because it looked at split-night observations. What does the future hold for sleep apnea research? Severe sleep apnea showed higher volumes of these biomarkers compared to mild or moderate cases.Īdjustments were made for age, sex, and relevant conditions. This was the equivalent of ageing 2.3 and three years, respectively. In this study, 140 individuals (average age 73) with obstructive sleep apnea were categorized as mild, moderate, or severe.Ī correlation was found between decreased deep sleep percentage and increased white matter hyperintensities and reduced axonal integrity. This reminds us just how important prevention and management are. These brain changes associated with sleep apnea currently lack treatment. “Finding that severe sleep apnea and a reduction in slow-wave sleep are associated with these biomarkers is important since there is no treatment for these changes in the brain, so we need to find ways to prevent them from happening or getting worse.” Carvalho, MD, MS, of the Mayo Clinic in Rochester, Minnesota, and a member of the American Academy of Neurology. “These biomarkers are sensitive signs of early cerebrovascular disease,” explains study author Diego Z. Sleep apnea and reduce deep sleep are associated with biomarkers indicating early cerebrovascular disease The other biomarker connects nerve cells and measures axon integrity. Apnea, depression, and metabolic abnormalities are independent predictors of excessive daytime sleepiness (EDS) in patients with sleep apnea. These hyperintensities become more common with age or uncontrolled high blood pressure. One biomarker, called white matter hyperintensities, refers to small lesions visible on brain scans.

Making gasping, snorting or choking noisesĭuring the day, you may also experience the following symptoms:.Symptoms of sleep apnea normally occur during sleep. ![]() Sleep apnea must be treated because it can lead to more serious problems.” The most common type is called obstructive sleep apnoea (OSA). ![]() ![]() What is sleep apnea?Īccording to the NHS, “Sleep apnea is when your breathing stops and starts while you sleep. The study examined sleep factors and biomarkers related to white matter health. The research, published online issue of Neurology®, the medical journal of the American Academy of Neurology, establishes an association, not causation, between sleep apnea and poor brain health. Sleep apnea patients with reduced deep sleep have a greater risk of brain biomarkers linked to stroke, Alzheimer’s, and cognitive decline ![]()
