Well, this article caught my attention (wavering though it is). Was diagnosed with APNEA several years ago and have followed treatment fairly well. However, not strictly as you have. I can change that. However, I'd like to know if you have seen any information on getting one's brain back not only from SA but in conjunction with age related effects. I am 77 and know I've lost considerable brain working quality, especially in the area of short term memory and problem solving. Your mention of loss of directionality caught me up short, as unexpectedly I'm finding location memory of recently acquired addresses difficult. Thank goodness for GPS.
I do have heart failure and other cardio difficulties, but have good care and am working to bring my energy levels up. I will increase excecise regularity and try to add items. With heart failure, too much exercise results in eliminating energy levels for a significant time, even the remainder of a day, which of course is truly frustrating and to some extent scary.
Have you tried 3 dimensional puzzles? They are very interesting and I expect helpful in this area. I have one and have procrastinated working it, but will attack the project starting this evening. As a note, I was amazed at the difference in capability of my daughter (52) when doing what look like truly difficult 3D puzzles and what I believe I shall find. However, tonight will begin. I've also gone back to working crochet direction projects, starting with a very simple child's sweater pattern. Am with you, believing these sorts of activities will help.
I'm a clay person, doing mostly sculptural hand building and finding my hands and fingers do not follow my directions smoothly and accurately. Forming smooth, smaller lines and forms is much more difficult and takes so much longer to achieve quality finished results.
What is age related and what is a result of both is unclear and probably unnecessary to be concerned about. If your three major changes help reduce these conditions I shall be most happy as well as relieved. Thank you for your full article as it has outlined help I can can easily follow and shine a brighter light on a situation which is highly disconcerting.
