New Research Shows Children with ASD Have Increased Hg Levels in Whole Blood, Red Blood Cells and Plasma

January 08, 2024

However, Hair and Urine Levels Were Similar Between Children With and Without the Disorder

A new meta-analysis has explored the potential connection between mercury (Hg) exposure and autism spectrum disorder (ASD). The analysis revealed that patients with autism had higher Hg levels in their whole blood, red blood cells (RBCs), and plasma compared to neurotypical children.  However, levels of Hg in hair and urine remained similar between the two groups. These findings support the theory that Hg is an environmental factor linked to the etiology of ASD. Additionally, the authors suggest that children with ASD could have impaired excretory mechanisms for removing Hg from their bodies. They also indicated that their findings suggest alternative explanations for these higher levels, such as different environmental exposure and increased Hg deposits in other body tissues, which could lead to decreased excretion. The analysis highlights the importance of non-invasive clinical tests such as hair, urine, and deciduous teeth in studying Hg exposure and its link to ASD. This research also recommends that future studies examine the level of Hg in other biological materials, such as nails and deciduous teeth enamel. These findings stress the need for international collaboration to reduce environmental Hg exposure and better understand the intricate connection between Hg exposure and ASD. The authors also call for further research to investigate reliable ways to decrease Hg levels in the bodies of children with ASD to reduce or prevent harmful effects.
