Manganese exposure: Neuropsychological and neurological symptoms and effects in welders

摘要: Manganese exposure reportedly may have an adverse effect on CNS function and mood. Sixty-two welders with clinical histories of to manganese were compared 46 matched regional controls chosen at random from a telephone directory. The following tests given: Wechsler Adult Intelligence Scale (WAIS-III), Memory (WMS-III), Boston Naming, WRAT-3, Cancellation H, Trail Making Tests A B, Auditory Consonant Trigrams, Stroop, Rey-Osterreith, Animal Controlled Oral Word Association (COWAT), Test Malingering, Rey 15-item, Fingertapping, Grooved Pegboard, Dynamometer, Visual Attention Test, Lanthony d-15 Color Vision, Vistech Contrast Sensitivity, Schirmer strips. administered shorter battery the Naming some subtests WAIS-III, WMS-III not administered. Mood tests, given both groups, included Symptom Checklist-40, Checklist-90-R, Profile Scale, Beck Depression Inventory II, Anxiety Inventory. Forty-seven 42 retained for statistical analysis after appropriate exclusions. Results showed high rate symptom prevalence pronounced deficits in motor skills, visuomotor tracking speed information processing, working memory, verbal skills delayed visuospatial skills. Neurological examinations neuropsychological test results suggest that neuropsychologists obtain significantly more mood symptoms overall. Odds ratios indicate highly elevated risk neurological symptomatology manganism. disturbances including anxiety, depression, confusion, impaired vision very odds ratios. exams exhibit complementarity differences, though methods be sensitive detecting early signs present study corroborates findings our previous another group welders.
