So I did a lot of independent reading over winter vacation and one of the books I read was The Sleep Rwvolution by Arianna Huffington. I think most of us know the importance of sleep especially for someone with our condition but one part really scared me--she cites a study that claims that taking benzodiazepines such as Xanax and restoril for more than 6 months increases risk of Alzheimer's by 84%. I'm not on these meds but it still freaked me out and was wondering if study was legitimate--it's from Bmj 349(2014):g5205 "Benzodiazepine use and risk of Alzheimer's disease: case-control study"
