Obstructive sleep apnea may directly cause early cognitive decline

By Mischa Dijkstra, Frontiers science writer Obstructive sleep apnea is a debilitating disease, which can lead to fragmented and poor sleep and daytime sleepiness Patients with obstructive sleep apnea (OSA) often show cognitive deficits, but these have traditionally been attributed to co-morbidities. But now researchers have shown for the first time that OSA itself is sufficient to cause early cognitive decline in middle-aged non-obese men. Obstructive sleep apnea (OSA) is a potentially dangerous condition. During sleep, the throat muscles of people with OSA relax and block the airflow into the lungs, so that they repeatedly stop breathing. Common symptoms of OSA include restless sleep, loud snoring, daytime sleepiness, and prolonged headaches in the morning – highly debilitating for patients and their partners. OSA is currently underdiagnosed: it may occur in as much as 15-30% of men and 10-15% of women, or approximately 1bn adults worldwide, of whom an estimated 80% don’t know they have it. Major risk factors for OSA include middle or old age, being obese, smoking, chronic nasal blockage, high blood pressure, and being male. Now, researchers from the UK, Germany, and Australia have shown for the first time that in middle-aged men, OSA can also cause early […]
