Input: Abstract: It is not uncommon for thyrotoxicosis to appear in an atypical manner in older patients. The classical symptoms are often absent. The disease is frequently characterized by cardiac, gastrointestinal, neuromuscular, and neuropsychiatric symptoms. As hyperthyroidism is readily amenable to effective treatment that can improve the quality of life, the clinical suspicion of this disease is always indicated and exclusion of this diagnosis should always be pursued. Recognizing the admittedly great difficulty in making, or even suspecting, the diagnosis of hyperthyroidism in the elderly, our rule is to test for hyperthyroidism in essentially all geriatric patients presenting chronic systemic symptoms or signs. On the other hand, we do not recommend community-wide screening of persons over 60 for hyperthyroidism. Community-wide screening falls far below the break-even point in cost-benefit analysis. The most sensible detector of hyperthyroidism now widely available is the serum free T3 index (FT3I), but it may be falsely normal because of the effect of systemic illness on extrathyroidal T4-to-T3 conversion. The advent of ultrasensitive methods for TSH may change these statements considerably. It may become the single screening procedure for both hyper- and hypothyroidism.
