Sleep apnea is a common sleep disorder that affects an estimated 30 million Americans according to the American Medical Association. However, only about six million people are diagnosed with this condition. This disorder can result in numerous negative side effects, including daytime sleepiness, a lack of focus, and an increased risk of numerous serious health issues, including memory loss! Read on to learn more about the connection between sleep apnea and your brain health.

What Is the Connection Between Sleep Apnea & Memory Loss?

In a recent study, a connection was found between sleep apnea and Alzheimer’s disease. Research found that damage in the brain begins in the same location and spreads similarly in sleep apnea and Alzheimer’s. Other studies have shown that those who have sleep apnea were diagnosed with mild cognitive impairment an average of 10 years earlier than those without sleep-breathing issues. Fortunately, researchers have also found that those who treated their sleep apnea were diagnosed with these issues approximately 10 years later than those whose issues weren’t treated. Ultimately, by addressing sleep apnea symptoms, you could reduce your risk of medical conditions related to cognitive impairment as you get older.
