I thought I would bring up a couple other things. You have mentioned Creatine at one point (I take creatine monohydrate largely because it is the cheapest and been around for years, but may or may not be the best). I had read somewhere (in a study, I believe) that it was recommended not just "as prescribed" for muscle performance, but also for general cellular ATP production assistance, and specifically in regards to NMD. In the end, it seems to me, it is the lack of cellular ATP that is the problem; in the muscles at least, this is supposed to be an end product of creatine supplementation. The mitochondria produce and export this molecule (ATP) known as the body's "energy currency." I wonder how much it is then able to perhaps exported from the cell itself to others in need? I will be looking for that answer.
I theorize exertion problems are due to the depletion of ATP. One of the things I will be researching if possible is how stable this molecule is and how far it can travel from the point of manufacturing. For instance, I do not know if ATP can be detected in the blood or is specifically transferred by the blood. I "tend to know" that it does not survive digestion, so that route is out. The reason I bring all this up is that it appears there is a systemic loss of ATP after exertion -- that for me, often shows up several hours after exertion -- or oddly, laying out in the sun for any length of time (maybe extra energy spent trying to stay cool? repairing celluar sun damage? etc.) It all appears to show up in my visual acuity too, and I suspect that is "visual interpretation" in the brain that's the problem rather than the eye not performing properly. Feeling down, arms less stable (with an associated slight "sensation" letting me know that they are weaker at the time) and visual fuzziness go hand in hand, plus the general lack of energy. Substandard mitochondria performance in ATP production might explain nearly all these symptoms. Did your doctor(s) comment on creatine?
BTW, this was to have been a busy day. I decided not to travel out-of-town due to feeling "statin effected/affected" today. No big deal, I'll do it Monday and do office work today.
If I do not get better overall over time, or get worse, I will just try to get use to the new me. I am learning everyday, it seems, how to anticipate and adapt. It could be that I will always just have a limited amount of energy -- which can be exceeded, but only at a cost a few hours later or the next day. On the flip side: The idea that exercise, as was mentioned in another thread, can increase the number of mitochondria in the cells is accurate as far as I understand -- feedback systems increase the number, over time, per demand -- at least in the muscles. The new ones may not have the production problems of the old ones. If there is a normal turn over, and if it is enhanced by exercise (which means walking in our case) that might be "the mechanism" for improvement over time, at least in the body, maybe not the brain? The mitochondria do not repair well from oxidative stress (free radicals) like the rest of the cell does. The machinery once damaged does not repair itself. But unless the DNA of the given mitochondria unit is also torn up, it should be able to replicate new mitochondria that are arguably perfect. That is what I am hoping for, and see a basis for, per my growing but limited knowledge of cellular biology. The extent of brain cell mitochondria replication -- and how to enhance it -- is another question. I will be looking to have find an answer. My own experience over time may be the only way I get answer.
bucho's experience has been inspiring. His year bench mark theory is giving me additional hope. Speaking of hope, there is more of a physical connection than we realize. It has been well shown that protein translations, for instance, are very effected by one's thoughts. Positive thinking has very positive physical, organic results -- particularly and firstly in the brain. If affects the wiring. It improves physical health and integrity of systems regardless of whether its based on a belief in science, in God, or Both...
OK, back to work...
