Nighttime apnea damages the brain

About 35% of Russian children often snoring would be the characteristic symptom of sleep apnea, a condition that up to 6% of the pediatric population suffers. Sleep apnea, also known as Sdb (Sleep disordered breathing), would be associated with acute and chronic changes in brain tissue, at least in children, while in adults there is more frequent increase in blood pressure, cardiovascular changes with behavioral consequences and negative neurocognitive. According to some Australian researchers, coordinated by Prof. Rosemary Horne, of the Monash University of Melbourne.

To assess brain tissue integrity and association with Sdb, the researchers used mean diffusivity (Md), a measure of biomedical imaging calculated through a magnetic resonance instrument called diffusion tensor imaging. In particular, the researchers considered 18 children with suspected Sdb and, as a control group, 20 children who did not snore. Compared to controls, children with Sdb tended to have lower Qi scores, Qi performance and full quotient, and showed a tendency to have more deficits on the basis of the results obtained in the Behavior Rating Inventory of Executive Function scales. Children with Sdb showed significantly lower Md values, which indicated the presence of acute lesions with swelling at the level of axons and neurons in different areas of the brain. The frontal and bilateral pre-frontal cortex of the children with Sdb showed an increase in the values of Md, which would reflect a chronic damage in the axons.

“This study shows that sleep apnea can not be ignored,” says Horne. Although there is an increasing correlation with the severity of the disorder, “even those children with less than one obstructive event per hour of sleep would have shown evidence of alteration in the brain”. The study was published on Sleep.

    Nice read, I just passed this onto a friend who was doing some research on that. And he just bought me lunch since I found it for him smile Therefore let me rephrase that: Thanks for lunch! “We know what happens to people who stay in the middle of the road.
