The neuroendocrine theory

First proposed by Professor Vladimir Dilman and Ward Dean MD, this theory postulates on wear and tear of the neuroendocrine system. Inneuroendocrine system, the master pituitary gland secrets hormones to direct other glands in secreting their hormones and works conjunction with the hypothalamus glands form a command post in the nervous system in closely direct the function of most of the body functions.
but as we age, the hypothalamus loses its ability as a hormone regulator as its receptors of which uptake other gland hormones become less sensitive to them, including sex hormones, DHEA, serotonin, melatonin, etc.
As for cortisol, a hormone secreted by the adrenal glands due to stress, is produced with abundance as we age.
