ADHD and neurotransmitters

In this report, it was found that children with attention deficit-hyperactivity disorder (ADHD) may have significantly altered levels of important neurotransmitters in the frontal region of the brain, according to a study published in the December 2003 issue of the Journal of Neuropsychiatry and Clinical Neurosciences. "Our data show children with ADHD had a two-and-half-fold increased level of glutamate, an excitatory brain chemical that can be toxic to nerve cells," said lead author Helen Courvoisie, M.D., assistant professor, division of child and adolescent psychiatry, department of psychiatry and behavioral sciences at the Johns Hopkins Medical Institutions, Baltimore. "The data also suggest a decreased level of GABA, a neuro-inhibitor. This combination may explain the behavior of children with poor impulse control." Environmental factors associated with ADHD include low birth weight, hypozia (too little oxygen) at birth, and exposure in utero to a number of toxins including alcohol, cocaine, and nicotine. Other studies have found correlations between certain toxic agents / nutrient deficiencies and learning disabilities. These include: * Calcium deficiency * High serum copper * Iron deficiency can cause irritability and attention deficits * Magnesium deficiency, which is characterized by fidgeting, anxiousness, restless, psycho- motor inability, and learning difficulties * Malnutrition in general is related to learning disabilities; the child does not have to look malnourished, a fact forgotten in affluent countries * Dyslexic children seem to have abnormal zinc and copper metabolism - low zinc and high copper * Iodine deficiencies have been linked to learning difficulties
