Abstract
In the elderly, primary hyperparathyroidism (HPT) is often disguised as ‘senility’ which can, however, be alleviated or cured by parathyroid surgery. The prevalence of HPT in the non-selected 75- to 85-year-old subjects (n = 610) randomly sampled from census records was estimated by measurements of serum ionized calcium and intact parathyrin levels. The prevalence of cases that require clinical attention seems to be around 3% in women and less than 1% in men. Furthermore, this study indicates that, on average, the serum ionized calcium concentration remains stable even in the elderly.Keywords
