[Secondary encephalopathy due to exposure to organic solvents: psychopathological, neuropsychological and neuroimaging findings].

Chronic exposure to organic solvents may cause permanent cognitive impairment. The nonspecify of neurological signs as the abnormalities of neurophysiological tests and morphological neuroimaging techniques have oblige the use of clinic neuropsychology in the monitorization of the neurotoxicity cause by these substances. The new modern functional neuroimaging techniques can contribute to the diagnosis of brain lesions caused by the exposure to organic solvents. We report a case that clearly supports this hypothesis as we emphasize the correlation found between clinical symptoms and the deficits obtained after the study of cerebral blood flow with single photon emission computed tomography (SPECT).
