Dear ALL, The following fascinating article appeared in a University of Rochester publication this morning: https://www.urmc.rochester.edu/news/story/5508/not-all-sleep-is-equal-when-it-comes-to-cleaning-the-brain.aspx It describes the cleansing of the brain of debris by cerebral spinal fluid during slow wave sleep, discovered previously at UR; and notes that, during surgery, especially on older adults, it's important to use the appropriate anaesthetics, ketamine and xylazine, so that the glymphatic system should work as it usually works during deep slow wave sleep, to clear the brain. (The wrong anaesthetics can allow plaques to accumulate. Clinical examples are given. An obvious observation, not mentioned in the article (for obvious reasons): Might it be conceivably eventually a method of helping people having difficulty achieving slow wave sleep, to be take (orally take or inject ?) these two anaesthetics in (who knows what ?) quantity before bed to achieve better quality sleep? (I don't recommend experimenting with this on yourselves; but it would be fascinating if some qualified sleep researcher managed to start a clinical study of this possible method of improving sleep quality on patients at risk of Alzheimers. Probably would be VERY hard to get FDA approval). -- Saul
Dear colleagues, I've just enrolled in a program called "Mindfulness Based Stress Reduction". It's a two hour evening program, repeated weekly for six sessions. It's given at the University of Rochester, Rochester, NY, where I work. The program is only open to employees and associates of the University of Rochester and their families; so very few people in these Forums are eligible. But you might find something similar where you work. The program here at UR is outstanding. It's a wonderful program that I've taken several times, and always come back to, whenever I can find it offered. Mindfulness is defined, roughly, as "being present in the moment". The concept takes it's roots in Asian philosophies, particularly Buddism. It's too difficult to really explain in a few words. When you regard the world and your existence mindfully, it helps to enjoy every moment, even the complicated ones. Meditating is a useful practice, that I sometimes engage in. Mindful living also usually improves sleep quality. I recommend it strongly. -- Saul
