The effect on memory of long-term exposure to organic solvents: A critical review

This review compares memory test results derived from studies revolving around the effect on memory of long term exposure to organic solvents. The comparison presents a variety of conclusions offered by the different researchers. The spectrum of conclusions ranges from negation of any effect on memory of organic solvents, to confirmation of memory decline under such exposure. Analysis of the findings does not determine conclusively whether or not there is a decline in memory resulting from long-term exposure to organic solvents. The difficulty in drawing conclusions is due to disparate methodologies, populations which differed in age, educational level, type of occupation, and the variety of exposure agents. In addition, memory tests used in the various studies differ significantly. The significance of each factor is discussed
