Unlabelled:
A review of neurotoxics is made, given the low tendency to investigate for chronic exposure to environmental and industrial potential central nervous system toxic substances (heavy metals, insecticides, organic solvents and carbon monoxide) in the history of a patient consulting for behavioral - cognitive complains, and considering the potential overturn of the disease if a correct diagnosis and early treatment is made.
Objective:
to determine the onset of the cognitive - behavioral features, presentation pattern, diagnosis and treatment of such neurotoxics (NT).
Methodology:
systematized search in Cochrane and Medline reviews, Embase and Lilacs.
Results:
chronic exposure to neurotoxics can produce personality changes (sleeping problems, excitation, depression, delusions and hallucinations) as well as cognitive problems (memory, learning, language and cognitive reaction problems). NT may cause changes in the neuron morphology and its sub cellular structures, affecting its normal biochemistry and physiology (proteins and neurotransmitters synthesis). The clinical history, diagnosis and treatment of each neurotoxic are discussed.
Conclusion:
The NT must be taken in consideration among the possible different etiologies when a patient with a bizarre behavioral cognitive syndrome is examined.

Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
