Obstructive sleep apnea (OSA) is a breathing disorder that causes persons to stop breathing hundreds of times during the night. This reduces the oxygen levels to the brain, which eventually cause memory problems.1 Untreated sleep apnea doubles a person’s Alzheimer’s disease risk.2 A Mayo Clinic patient with concentration issues was diagnosed with sleep apnea, and within a year of treatment, the patient’s neuropsychological tests were in the normal range.3

Some risk factors for sleep apnea are excess weight, family history, being male, smoking, nasal congestion from allergies, and having a narrow throat.4 Women are often under diagnosed.5 Untreated sleep apnea can also lead to daytime fatigue, high blood pressure, stroke, heart problems, and diabetes.6 Loud snoring is a symptom of OSA so anyone who snores loudly should be screened for sleep apnea.
