[Dysthyroidism in elderly patients. Clinical characteristics].
FROM A CLINICAL POINT OF VIEW: Diagnosis of dysthyroidism in the elderly is particularly difficult because of the lack of sensitivity and specificity of classical symptoms and examinations. Neuro-mental and cardiovascular signs are frequent: dysthyroidism should always be searched for in the presence of dementia, depressive syndrome, heart failure or tachyarrhythmia. BIOLOGICAL DATA: Simple screening must therefore be widely proposed and relies on complete thyroid stimulating hormone (TSH) assay, further completed by free thyroid hormone assay. Biological diagnosis is easy in the healthy elderly patient, but interpretation of the assays is delicate in the case of intercurrent diseases or treatment with amiodarone. THE CAUSES TO BE LOOKED FOR: The detection of hypothyroidism does not require etiological exploration, other than the search for iodine overload. In cases of hyperthyroidism, scanning usually reveals a nodular goitre. THERAPEUTIC REGIMENS: In most cases treatment is simple. Replacement therapy is used for hypothyroidism. Patience and cardiovascular monitoring are essential. In the absence of iodine overload or compressive goitre, radioactive iodine is the treatment of choice. These simple treatments avoid the loss of physical and mental autonomy and cardiovascular complications. The importance of screening of these so-called "profitable" diseases in the elderly is obvious.
