Thanks for the link even though I find it somewhat disturbing. For the past several months I have been waking around 3 A.M. regardless of the time I go to bed unable to go back to sleep for hours. The link indicates drugs prescribed for sleep do not provide quality sleep. I had a major TBI and several subsequent concussions in my youth. The link indicates lack of sleep causes increased tau protein and amyloid. Seems I could be priming for Alzheimer's but an MRI is not in the cards for me because of stainless steel wires used to fuse my skull after craniotomy. Maybe a blood test is available to see if any biomarkers indicate early alz. that could qualify me for the trial. Just trying to stay ahead of the curve. Thanks for the info.
