[00:00:00]Testosterone.

[00:00:01]This sex steroid hormone, which is present in both women and men, but at higher concentrations in men, supports the survival of neurons, memory, and spatial ability.

[00:00:10]This is in addition to its beneficial effects on our drive, strength-building capacity, bone mineral density, and overall mood and sense of well-being.

[00:00:17]Dr. Bredesen wants total testosterone at 500 to 1,000 ng per deciliter and free testosterone at 6.6 to 15 ng per deciliter. Cortisol.

[00:00:29]Like we've talked about in past videos, constant high levels of cortisol damage neurons, especially the memory center of the brain, the hippocampus.

[00:00:36]This is why chronic stress is an important contributor to cognitive decline.

[00:00:40]There comes a time when if the chronic stress never ends, the adrenal glands get pooped out. This adrenal fatigue then leads to the body having trouble producing any cortisol, making us vulnerable to infections, toxins, or any other stressors.
