Higher HGH and BDNF levels are claimed to improve learning capacity and memory by helping the brain form new connections. The mental health effects of hormonal change during perimenopause are mechanistically analogous to the effects sometimes observed when changing oral contraceptives. Longitudinal hormone testing approximately four times per year allows clinically meaningful patterns to emerge over time. The article does not provide specific hormone names or exposure details for the hormonal effects it mentions. Waiting for severe hormone depletion before treating represents a failure of preventive reasoning because downstream damage accrues before symptoms become unmistakable. Perimenopausal hormone levels can swing dramatically cycle to cycle, making a single blood test an unreliable measure of hormonal trajectory. Testosterone is described as beginning to decline…
