Snoring and sleep deprivation increase risk of Alzheimer's and stroke - neurologist Alekhina.

The importance of a good night's sleep for your health is absolutely undeniable.. Research continues to reveal the bad effects of poor sleep, ranging from a higher risk of heart attacks to a weaker immune system..

New study suggests people who snore may be at higher risk of Alzheimer's and strokes.

Sleep apnea occurs when your breathing stops and starts during sleep.

Research team studied sleep factors and biomarkers of white matter health.

One of the biomarkers the team looked at was white matter hyperintensity, which describes the tiny lesions seen on brain scans..

Snoring may herald a deadly disease Another biomarker measures the integrity of the axons that form the nerve fibers that connect nerve cells.

“Finding that severe sleep apnea and decreased non-REM sleep are associated with these biomarkers is important because there is no cure for these brain changes, so we need to find ways to prevent them from occurring or worsening.”.

The researchers came to their conclusions by studying 140 people with obstructive sleep apnea syndrome..

Snoring was called a harbinger of a deadly disease Participants, who were 73 years old on average, underwent brain scans and had to spend the night in a sleep lab. These subjects had no cognitive problems at baseline and did not develop dementia by the end of the study..

For every 10 point decrease in the percentage of slow-wave sleep, white matter hyperintensity increased - similar to the effect of age by 2.3 years.
