Background:Methyl isocynate (MIC) is a reactive, toxic, volatile and inflammable gas. Exposure to MIC causes neurotoxicity and somatic abnormalities in human beings.Aim:We compared neurocognitive function in MIC-exposed women and a control group, as well as cognitive function in the MIC group and examined them with reference to age.Methods:The study sample comprised 30 women and a control group of 30 women. Both the groups were subjected to a detailed neuropsychiatric examination along with assessment of neurocognitive function using the PGI-Battery of Brain Dysfunction (PGI-BBD).Results:Mean scores of immediate recall, visual retention, difference in performance quotient/verbal quotient, Nahar–Bensen and Bender–Gestalt test were significantly affected in MIC-exposed women. However, among MIC-exposed women, neurocognitive functions were similarly affected in women in various age groups.Conclusion:Women in the MIC-exposed group had significant neurocognitive dysfunction in some specific areas as compared to women in the control group. The mean score of dysfunction rating of the PGI-BBD showed significant differences in neurocognitive functions between MIC-exposed and non-exposed women.
