Children with autism spectrum disorders show lower plasma magnesium levels compared to neurotypical children. Early diagnosis and dietary interventions may benefit these children.

Area of Science:

  • Biochemistry
  • Pediatrics
  • Neurodevelopmental Disorders

Background:

  • Autism spectrum disorders (ASD) are complex neurodevelopmental conditions.
  • Magnesium (Mg) plays a crucial role in numerous biochemical processes.
  • Previous research on magnesium levels in ASD has yielded mixed results.

Purpose of the Study:

  • To compare plasma and erythrocyte magnesium concentrations in children with autism spectrum disorders, Rett syndrome, and neurotypical controls.
  • To investigate potential correlations between magnesium levels and neurodevelopmental status.

Main Methods:

  • Plasma and erythrocyte magnesium levels were measured in 12 autistic children, 17 children with other autistic spectrum disorders, 5 girls with Rett syndrome, and 14 age-matched neurotypical children.
  • Statistical analysis was performed to compare magnesium concentrations between groups.

Main Results:

  • No significant differences in intracellular magnesium were observed between control and pathological groups.
  • Autistic children and those with other autistic spectrum disorders exhibited significantly lower plasma magnesium concentrations compared to normal subjects (p=0.013 and p=0.02, respectively).

Conclusions:

  • Children with autistic spectrum disorders may have altered plasma magnesium levels.
  • These findings suggest that children with ASD may benefit from specialized dietary management, particularly if diagnosed early.
  • Further research with larger cohorts is warranted to confirm these findings and explore therapeutic implications.
