ICD-11 definition : Lead encephalopathy is much rarer in adults than in children because the mature adult
brain is more able to sequester lead away from its mitochondrial site of action within
cerebral and cerebellar neurons. Lead acts as a cellular toxin by inhibiting mitochondrial
respiration. Lesions in the central nervous system are thought to be the result of
vascular injury.;
