COPPER (Trace Mineral) Excessive copper in children is associated with hyperactive behavior, learning disorders such as dyslexia, ADD and infections such as ear. http://www.chemicalbalance.com/copper.htm
Serum zinc correlates with parent- and teacher- rated inattention in children with attention-deficit/hyperactivity disorder. These findings add to accumulating evidence for a possible role of zinc in ADHD, even for middle-class Americans, and, for the first time, suggest a special relationship to inattentive symptoms. They do not establish either that zinc deficiency causes ADHD nor that ADHD should be treated with zinc. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16190794
ZINC DEFICIENCY, METAL METABOLISM, AND BEHAVIOR DISORDERS The high incidence of zinc deficiency in assaultive young males was illustrated in a recent study1 which found elevated serum copper and depressed plasma zinc concentration, compared to normal controls. This study confirmed our clinical observations of zinc depletion in more than 4,000 behavior disordered patients. http://www.hriptc.org/zinc_deficiency.html
Zinc 'helps hyperactive children' Doctors have found evidence to suggest that hyperactive children may benefit from taking zinc supplements. http://news.bbc.co.uk/2/hi/health/3608439.stm
Zinc in Endocrinology In this paper, the interrelationships between zinc and growth, gonadal function, thyroid function and glucose metabolism will be discussed. http://www.int-pediatrics.org/newip/volumes/16%2C2%2C3%2C4/16-3/review/kaji/zincinendo.htm
Zinc supplements improve adolescents' mental performance Dr. Penland and colleagues found that supplementation with 20 milligrams zinc per week led to greater memory and attention abilities than those demonstrated by children who did not receive zinc. Visual memory reaction time was lowered by 12 percent in those who received zinc compared to 6 percent in those who received no supplements. Word recognition and attention similarly improved in the group who received 20 milligrams. http://www.wholeearthhealth.com/articles/APR0405.asp
