Neuropsychological sequelae in subacute home chlordane poisoning: Ten case studies

Chlordane is a potent neurotoxin and animal carcinogen, yet the frequency and severity of injury due to exposure from inhalation or contact in the home has not been widely documented. Neuropsychological dysfunction and emotional distress were observed in 10 individuals exposed to chlordane pesticide after their homes were treated for termites. Cognitive deficits ranged from mild to moderate on tasks requiring speeded processing, problem solving, and delayed memory. Somatization, hysterical features, and depression dominated the clinical picture. Current results implicate the hazards associated with chlordane treatment of residential homes and the continued need for further studies.
