Title A study of cognitive functions in DDT sprayers
Bibliographic information 1984, Vol.22, No.3, p.199-206. 20 ref.
Abstract Organochlorine pesticides are widely used in India and other developing countries. To study the effects of occupational exposure to DDT, 29 sprayers were subjected to clinical evaluation, the Bhatia battery performance test of intelligence, the Wechsler memory scale and the Bender visuomotor Gestalt test. Blood tests showed that DDT levels in the sprayers were 8.5 times higher than in controls. Intelligence and memory did not differ significantly from control values, but visuomotor function did. Over half of the sprayers with poor visuomotor performance had diffuse electroencephalographic changes. Visuomotor performance scores were correlated with DDT levels. This suggests a role of DDT in the impairment of cognitive functions.
