Lupron, Brain Function, and the Keto Diet

Lupron, Brain Function, and the Keto Diet

Reproductive senescence, the period of time in a woman’s life marked by the slowing and eventual cessation of reproductive function, frequently coincides with an increased risk of a host of neurodegenerative disorders from memory impairment to dementia and Alzheimer’s disease. Researchers have long postulated that the loss of ovarian hormones were responsible; estradiol, in particular, but likely others as well. This begs the question, what happens to the brain when we abruptly and artificially derail ovarian hormone synthesis in young women using drugs such as Lupron (leuprolide) and the other GnRH agonists and antagonists or by removing the ovaries altogether as in surgical oophorectomy? Is it the same damage we see in aging, only expedited and perhaps magnified or does it run a different course? Along those same lines, though perhaps a topic for another day, what happens when we chronically supplant endogenous ovarian hormone production with synthetic hormones such as those used in hormonal birth control or menopausal hormone replacement therapies? I suspect, and there is evidence to back up my suspicions, that in all cases brain function is altered, and not for the better. The mechanisms by which estradiol and other steroid hormones influence brain function are myriad and complicated. Beyond just reproduction, steroid hormones influence all aspects of neurological function, with estrogen, androgen, gluccocorticoid (cortisol) and mineralocorticoid (electrolyte balance, blood pressure) located throughout the brain. Steroid hormones produced in the body, because of their fat solubility, easily cross the blood brain barrier where they bind to their receptors and regulate all sorts of processes. Perhaps even more remarkable, the brain has all of the machinery to synthesize its own steroid hormones and so when body concentrations fall, at least for a time, the brain can compensate. Eventually, however, brain synthesis declines and that is where we […]
