Exposure to aliphatic hydrocarbons is an uncommon cause of headache, dizziness and memory loss. Occupational exposures, such as working in an unprotected environment for many years are the most common source (e.g. Grober and Schaumberg, 2000). Sometimes solvents are inhaled as a form of abuse, such as in toluene intoxication. Organic solvents are widely used in both industrial and consumer products. Alteration of olfaction, neurasthenic symptoms, and imbalance are commonly encountered in these situations (Kelefant et al, 1994).
