The brain does not operate independently of the body supplying it. It runs on the same hormones, the same mitochondria, and the same circulation as everything else, and it is unusually sensitive to all three. Which means that when something changes cognitively, the useful question is rarely what to add. It is what changed underneath.
That is why this program measures first. Hormonal, metabolic, and sleep variables are assessed together, so your plan works on the whole system rather than the readout alone.
This Houston program starts from the panel. What presents as a cognitive complaint often traces back to thyroid, to hormonal status, or to sleep, and your plan is sequenced around exactly what your panel shows.
