Often mycoplasmal infections remain without symptoms until the victim suffers a traumatic event (stress, injury, accident etc.) These stressing events enable the mycoplasma to begin consumption of cholesterol and symptoms may begin to present.

Cholesterol is vitally important for brain function. While your brain represents about 2-3% of your total body weight, 25% of the cholesterol in your body is found in your brain, where it plays important roles in such things as membrane function, acts as an antioxidant, and serves as the raw material from which we are able to make things like progesterone, estrogen, cortisol, testosterone and even vitamin D.
