Mercury (Hg) is a liquid, toxic, heavy, silvery-white and odorless metal. Its use is identified by several ancient peoples, with its use evidenced mainly for the extraction of gold, alchemy, among others. This metal can be presented in several chemical forms: metallic, ionic Hg +, Hg ++ and organic compounds, highly volatile and soluble in water and lipids; factor that intensifies contamination by transposition through pulmonary alveoli and the blood-brain barrier, as well as fixation and damage to the nervous system, resulting in great reactivity with sulfhydryl groups, inhibition of several enzymes and autoimmune action. Thus, the objective of this study is to describe the main direct and indirect impacts on human neurocognition, resulting from poisoning by mercury (methylmercury). It was possible to verify that in the literature, many studies demonstrate that women, children and individuals who deal directly with mercury display sources, are the main targets for this intoxication. In addition, it can be seen that neurological damage is serious and can even reach the fetus, by breaking barriers in the placenta. Thus, studies that demonstrate and emphasize the neurodegenerative effects caused by high doses of mercury in the body are of fundamental importance, in addition to strengthening information about this metal, which is very harmful to human health.
