HYPERACTIVITY LINKED TO THYROID HORMONES Thyroid hormone may play a role in the hyperactive and impulsive symptoms of children with attention deficit-hyperactivity disorder (ADHD), University of Maryland School of Medicine researchers say. Dr. Peter Hauser, professor of psychiatry, and Dr. Bruce Weintraub, professor of medicine at the University of Maryland School of Medicine, have found a positive correlation between elevated levels of certain thyroid hormones and hyperactivity/impulsivity in a selected group of patients. They report on their research in the February issue of the international journal Psychoneuroendocrinology.

The easy, relaxed lifestyle experienced by our ancestors no longer exists, and we're not even aware of how much stress we're under. The problem? "Our lifestyles have changed, but our bodies haven't," Dr. James Wilson said in his November lecture at the First Arizona Choices Exposition in Tucson, Ariz. A large portion of our population is feeling tired and stressed out, and we want to know why.

Abstract. "Replacement" is the most widely used approach to thyroid hormone therapy. Clinical practice guidelines define replacement therapy as: adjustment of a patient’s thyroid hormone dosage so that his or her TSH and thyroid hormone levels remain within current laboratory reference ranges. Overall, the endocrinology specialty endorses T4-replacement as the preferable approach to thyroid hormone therapy.
