OBJECTIVE: To determine if aging modifies the clinical presentation of hypothyroidism. DESIGN: Comparison of 24 clinical signs of hypothyroidism between elderly patients (> or = 70 years of age) and younger patients (< or = 55 years of age). SETTING: Prospective study of patients with chemically confirmed overt hypothyroidism. PATIENTS: Sixty seven elderly patients (79.3 +/- 6.7 years) and 54 younger patients (40.8 +/- 9 years) were included in the study. RESULTS: Neither mean duration of evolution nor mean thyroid-stimulating hormone (TSH) level were different between the 2 groups. Two signs were found in more than 50% of the elderly patients (fatigue and weakness). Four signs were significantly less frequent in elderly patients (chilliness, paresthesiae, weight gain, and cramps). Mean number of clinical signs in the elderly (6.6 +/- 4) was significantly smaller than in young patients (9.3 +/- 4.7) (P < 0.01). CONCLUSIONS: Our results suggest that the presentation of hypothyroidism is altered in the elderly in comparison with young patients in that there are (1) fewer signs or symptoms and (2) diminished frequency of some classical signs. Our results underline the importance of TSH measurement in the elderly.
