In the article “Time may not fully attenuate solvent-associated cognitive deficits in highly exposed workers” by E.L. Sabbath et al. (Neurology® 2014;82:1716–1723), there is an error in the Methods. The authors listed hydrazine as an example of petroleum solvent and toluene diisocyanate as an example of a nonbenzene aromatic solvent; however, toluene diisocyanate and hydrazine were not included in any analyses because they are not solvents. The first sentence under “Exposure” should have read: “A job exposure matrix (JEM) was used to characterize lifetime exposure to 4 categories of organic solvents: chlorinated solvents (all species combined, plus separate assessments of tetrachloromethane, trichloroethylene, perchloroethylene, dichloromethane, trichloroethane), petroleum solvents (all species combined), benzene, and nonbenzene aromatic solvents (all species combined).” The results and conclusions of the paper are not affected by this correction. The authors regret the error.
