Neurologic complications associated with gold therapy for rheumatoid arthritis.

Neurologic complications of gold are rare and include peripheral neuropathy, a Guillain-Barré-type syndrome, cranial nerve palsies and encephalopathy. Three cases of cranial neuropathy complicating chrysotherapy for rheumatoid arthritis are described. One also had a sensorimotor neuropathy associated with segmental demyelination and axonal degeneration, and another developed an encephalopathy which, on contrast enhanced computed tomographic scanning, showed reversible cerebral and cerebellar white matter lesions. Early recognition and prompt withdrawal of chrysotherapy are the mainstay of management of this lesser known complication.
