title: Increased levels of adrenocortical and gonadal hormones in mild to moderate Alzheimer's disease.
abstract: Hormonal changes during normal aging include decreasing levels of gonadal hormones and adrenal androgens. These hormones influence multiple nervous functions, including cognition and mood. Related to this, abnormalities at several levels of the hypothalamic-pituitary-adrenal axis (HPA) have been reported in patients with Alzheimer's disease (AD). We studied steroid hormones in 33 patients with mild to moderate AD (12 men; 21 women, 76.4 +/- 7.8 years) and 22 healthy elderly controls (10 men; 12 women, 75.4 +/- 7.5 years old, respectively). Basal levels of serum cortisol, dehydroepiandrosterone (DHEA) and androstenedione were significantly increased in AD patients. Women with AD had significantly higher levels of DHEA and androstenedione. Serum estradiol levels were non-significantly increased in women with AD. After adjustment for age and BMI women with AD had significantly increased levels of androstenedione and DHEA. Increased gonadal hormone levels in mild to moderate AD may reflect an increased secretion, and/or alterations in metabolism of these hormones. This may influence the symptomatology and progression of the disease.
