Gold induced encephalopathy: case report.

We describe a case with neurologic disease manifested as encephalopathy, generalized muscle fasciculations, and peripheral neuropathy occurring in a patient treated with therapeutic doses of gold for presumed rheumatoid arthritis. The illness remitted promptly during chelation therapy with dimercaprol (BAL). A review of the limited experience in the literature with the central nervous system toxicity of gold is given.
