Answer

Manganese encephalopathy

Excess manganese (Mn) can cause several neurotoxic effects. Herrero Hernandez et al described an epileptic syndrome due to manganese intoxication in a 3-year-old boy. EEG showed progressive encephalopathy. The patient developed epileptic status. Chelating treatment promptly succeeded in reverting epileptic symptoms. [75]
