[Hyperthyroidism in the elderly. The clinical forms. The incidence of signs and symptoms. The evolutionary features]

The last 15 years, 1939 patients suffering from different clinical forms of hyperthyroidism were hospitalised in the Clinic of Endocrinology of Iaşi. The frequency of the disease increases with age, especially for the toxic nodular goitre. In older patients we have noted a non-typical clinical course of the disease, with prevailing cardiovascular signs and weight loss. The clinical course is also particular especially because of the associated pathology. We have made some theoretical considerations concerning the possible explanations of these phenomena.
