Researchers investigated the concentrations of 15 heavy metals in the urine of 190 children between 6 and 15 years old
A new study points out that exposure to heavy metals may be associated with the prevalence of care deficit disorder with hyperactivity (ADHD). The conclusion is from researchers at the Universitat Rovira I Virgili, from Spain.
The team investigated the concentrations of 15 substances in the urine of 190 children aged 6 to 15. Of this total, 124 were diagnosed with the condition. The research was published in the Journal of Attention Disorders.
Lead, cadmium, copper and antimony can increase chances of the disorder
According to scientists, children with the largest amount of lead, cadmium, copper and antimony in the urine showed a higher incidence of ADHD. In addition, high copper and cadmium levels have been associated with more severe inattention symptoms, and larger copper and antimony may be linked to an increase in hyperactivity-impulsivity behaviors.
All analyzed metals are part of our daily lives and may have reduced exposure from some small actions. The use of water filters, practicing good hygiene and avoiding excessive grain consumption, such as rice, wheat and barley, are some alternatives.
Despite the research result, it is important to note that there is no proof that the elements cause ADHD. In addition, the study only analyzed external elements, without taking into account genetic issues, considered the causes of the condition.
