Hyperparathyroidism in the elderly.

Primary hyperparathyroidism seems to be increasing in incidence in elderly patients. Their symptoms are somewhat different from those encountered in younger patients, the most striking difference being the increase in the number of patients with mental changes. Twenty-nine patients, 23 women and 6 men, were treated at two community hospitals. Surgery was successful in all instances with no postoperative mortality and a low rate of complications. When properly evaluated, elderly patients tolerate parathyroid exploration very satisfactorily.
