Sleep apnea, the disorder that causes a person to stop breathing suddenly while sleeping, is already known to increase the risk of high blood pressure, heart failure, and daytime sleepiness.

A new study suggests that the sleep disorder is also linked with small brain lesions and a symptomless form of stroke, known as silent stroke.

In the study, 56 men and women ( aged 44 to 75 years) who’d had a recent stroke or TIA underwent overnight polysomnograms.  91% had sleep apnea.

Furthermore, having more than five episodes of sleep apnea in a night was linked with having multiple extra “silent strokes” on their brain imaging studies.

Silent strokes don’t cause any symptoms as they occur, so a person typically doesn’t know he or she has suffered one, but they can eventually lead to memory loss and difficulties with walking, as their effects accumulate over the years.”

Yet another reason to take the on-line sleepiness test, and if your score is >10 see a sleep specialist and/or get an overnight polysomnogram in a certified sleep laboratory.

Sleep disorders are common and underdiagnosed. Studies have shown that initial consultation and follow-up with a fellowship trained sleep medicine physician is more likely to resolve symptoms than direct referral for a polysomnogram by a primary care physician.

If you think you might have a sleep disorder, ask your doctor for a referral to a sleep medicine specialist!
