Abstract:
Long-term exposure to lead is known to cause a variety of neurotoxic manifestations, including symptoms of depression. Dimercaptosuccinic acid (DMSA), a recently approved oral chelating agent, can diminish the body burden of lead, but few cases of documented clinical improvement following treatment have been reported. We report a case of moderate to severe depression in a long-term lead worker that appeared to respond dramatically to DMSA. This response suggests a possible therapeutic role for DMSA in the treatment of depression in lead-exposed patients.
