Abstract: [Objective] The cognitive function of patients with occupational chronic benzene poisoning was investigated.[Methods] The Montreal cognitive assessment(Mo CA) was used to survey both 39 patients with occupational chronic benzene poisoning and 39 healthy subjects. [Results] The survey showed that difference of Mo CA testing scores between these two groups(24.10 ± 3.82 vs. 25.36 ± 2.34)had no statistical significance(P > 0.05). However,there were statistically significant differences of 3 factors including the visuospatial and executive functions,naming functions, and attention between them(P =0.001,0.029,0.034,respectively). [Conclusion] The patients with occupational chronic benzene poisoning might have damages to central nervous system on aspects related to visuospatial and executive functions,naming functions,and attention.
