Answer

Answer

Lead

The heavy metal lead is usually absorbed into the body by ingestion and/or inhalation. Symptoms from acute poisoning may range from lethargy, seizures, coma, and death to cognitive impairment, delirium, ataxia and distal motor neuropathy with chronic exposure. [70, 71] Stewart et al found lead to be linked to neurodegeneration with cumulative exposure leading to decreased brain volumes and white matter lesions. [72] Treatment includes chelation therapy and removing the source of the lead exposure from the patient's environment (see Lead Encephalopathy).
