Diagnosing neurotoxic exposure involves a combination of clinical evaluation, history taking, and laboratory tests. Clinicians often rely on symptomatology and exposure history to make a preliminary diagnosis. Laboratory tests can include blood and urine analyses to detect toxicants or their metabolites. Advanced imaging techniques, such as MRI or PET scans, can help assess structural or functional changes in the brain. Comprehensive neuropsychological assessments may also be employed to evaluate cognitive and behavioral effects.
