[Chemical substances, work and neurologic changes: possible relationships between those variables]

Authors searched 239 reports of patients admitted in a hospital who carried neurological pathologies with unknown etiologies in order to find the possible relationship between the disease and the occupational use of chemical substances. They found the occupation in 32 reports. 37.50% of the patients worked with agriculture; 34.37% were maids/worked at home; 12.50% were masons; one was a shoemaker, one a saddler; one made furniture and the others worked with machines. Considering their activities, they possibly used chemical substances. Few information relating this utilization and the presented disease showed the reduced importance given to these variables.
