@leokitten sure, but Cfs ppl even after +20 years of sickness dont show any sign of progression in this way. No dyskinesia or other sign that would show a progression in lowering dopamine over time. So the theory here would be it gets lowered once and then stays there forever ? without any progression or worsening in dopamine levels ever again ? Doesnt sound very plausible to me.
Also another prime example is people with depression and serotonin. If the neuroinflammatory and monoamine hypothesis of depression is true, then by your account I untreated depressed people should have progressively worse serotonin levels until they basically don’t have much serotonin anymore, but this isn’t the case. People can go decades with chronic lower activity or dysfunction without further neurotransmitter degradation.
