no
there are several types of mitochondria iirc but the most likely explanations for mental problems with illnesses like ME and soem others are that SEVERAL problems caused by the main illness affect the brain and central nervous system
poor heart function/blood volume/pumping reduces blood flow round the brain
the brain burns up 1/3rd of our energy intake, that is an ENORMOUS amount of power drain form your over all supply
the hypothalamus pituitary adrenal glands are affected,
these have many complex and peculiar interactions
for example I have almost no testosterone output because my pituitary gland is malfunctioning, so my testes production fo testosterone is turned off
this has major impact on over all bodily health
reactive hypoglycaemia seems a not uncommon problem with ME patients, so when we eat sugars or perhaps certain types of starch, our body goes whacky and reduces available blood sugar
I wonder if this is an immune system trigger to deal with infections, by starving them of sugar to feed on, that is wrongly triggered by whatever ME exactly is?
and other things as well
one effect of ALL these things is to cause me to be obese and deconditioned as I cannot exercise etc
this causes even more reduction in bodily efficiency
so if say it gets a 10 to 20% reduction in the necessary blood/nutrients to the brain, that is a real major reduction in what our brains can do
also, since there is good evidence for autoimmune issues it maybe the brain and central nervous system are being damaged, after all what many KEPT forgetting thanks t the psych bastards, is autopsies over the years have shown damage in the brain stem where something, probably autoimmune action, has inflamed and damaged sensory nerves coming back to the brain
so they are probably "shorting out" much like an electrical or electronic device
this would explain some of the awful sensory things we suffer
so, brain mitochondria MAY be messed up for us, but there's a whole LOT of other things that will cause us serious mental problems from reading to balance, to false sensory inputs (pain etc I have lost most of my sense of smell and yet smell some odd smells, ghastly, dont' smell like ANYTHING I've ever encountered in my life, but very unreal from things I KNOW don't smell like that, for example a perfume may smell of a terrible chemical harsh smell instead)
in other words, we're screwed
