Study of Brain Function in Women With Insulin Resistant Polycystic Ovary Syndrome
Study of Brain Function in Women With Insulin Resistant Polycystic Ovary Syndrome
The purpose of this study is to evaluate the effects of insulin resistance on brain function
 in women with Polycystic Ovary Syndrome (PCOS). PCOS affected women will be evaluated prior
 to and following 4-month treatment with Metformin. Additionally, brain function in women with
 PCOS will be compared to the brain activity in normal control subjects with regular menstrual
 cycles.
The pathogenesis of Polycystic Ovary Syndrome (PCOS), a reproductive and metabolic disorder,
 is associated with insulin resistance. The effects of insulin resistance on cognition, mood,
 opioid system and reproductive function in PCOS affected women are investigated in the
 current study. The identification of reversible changes in brain function and reproductive
 measures in insulin resistant PCOS patients would likely significantly influence treatment
 protocols for these young women.

 1. Evaluate the differences in opioid tone in women with insulin resistant PCOS compared to
 normal controls.

 2. Evaluate whether an oral hypoglycemic agent is capable of altering opioid tone in women
 with insulin resistant PCOS.
