Bromide intoxication in the elderly.

Four patients with dysfunction of the central nervous system secondary to bromide intoxication are reported. Three of them were referred because of symptoms of "senility," which appeared to preclude further independent living. After diagnosis and treatment of the bromism, they were able to continue living at home. The development of bromide toxicity with relatively low serum bromide levels in the elderly is discussed. The importance of a home visit to establish the diagnosis of drug-induced cognitive dysfunction is emphasized.
