Excerpt

Hyperthyroidism in the elderly is a serious clinical condition that is associated with significant morbidity. It may be difficult to diagnose due to the confounding effects of drugs and acute or chronic illnesses on the interpretation of thyroid function tests. In addition, there is a relative paucity of typical hyperadrenergic symptoms in older patients with hyperthyroidism, who instead may present with unexplained weight loss, neurocognitive changes, or cardiovascular effects. Of particular concern is the elevated risk of atrial fibrillation and cardiovascular complications in this age group. There is increasing evidence that even mild (subclinical) hyperthyroidism in the elderly is associated with these risks. Graves’ Disease and toxic multinodular goiter are the most common etiologies of hyperthyroidism in the elderly, although other causes of hyperthyroidism also occur. The use of amiodarone or administration of iodinated contrast agents can also lead to hyperthyroidism, and are commonly prescribed to older patients. Radioiodine or thionamide therapy are typically used to treat hyperthyroidism in older patients. Treatment decisions must be individualized, taking into account projected lifespan, comorbidities, and side effects of therapy.
