Sex hormones impact brain & mind massively.

 Sexual, adrenal & thyroid hormones, acting in concert, powerfully influence both the normal & disordered brain, including its limbic portions, particularly the amygdala, cingulate gyrus, pre-frontal cortex & hippo campus so critical to our feelings. Optimizing hormone levels & patterns, particularly those of estradiol & testosterone while limiting the negative influences of cortisol & progesterone has the capacity, both short term & long, to reduce both the risk & progression of conditions such as Parkinson's disease, head & spinal cord injury, stroke & dementia.
