Sleep Apnea Associated With Alzheimer ’ s Protein Build-Up

BOSTON (CBS) — A new study from the Mayo Clinic finds that people with sleep apnea may have higher accumulations of a toxic protein associated with Alzheimer’s disease in their brains. People with obstructive sleep apnea stop breathing periodically while sleeping which can cause a variety of health issues. Researchers looked at 288 people over 65 without dementia. Those whose bed partners said they stopped breathing while sleeping had a 4 1/2 percent higher level of tau in their brains than people without witnessed sleep apnea. Tau is a protein that clumps in the brains of people with Alzheimer’s which contributes to memory loss. Researchers say it’s still not clear whether the sleep apnea causes tau to build-up or whether the build-up of tau in the brain causes sleep apnea. That will have to be teased out with longer studies.

Millions of people with post-traumatic stress disorder (PTSD) — from veterans to rape survivors — have new hope because of a watershed study showing that the injection of an anesthetic to a bundle of nerves in the neck can relieve their symptoms in a clinically significant way. The treatment is known as the stellate ganglion block, or SGB. Used since 1925 for problems such as pain in the arm and shingles, it is safe and effective. In the newly released, eight-week, U.S. Army-funded clinical trial of 108 active-duty service members with PTSD, the nonprofit research institute RTI International found that patients...
