SERUM MANGANESE LEVELS IN CHILDREN WITH ATTENTION DEFICIT HYPERACTIVE DISORDER

Abstract

DHD has increased in prevalence over the past several years leading many to look for environmental factors responsible for this rise. The major goal of the present study was to examine the relationship between the incidence of ADHD and serum Mn levels in school aged children. The study comprised 40 children with ADHD and 20 controls, all of whom are living in and around Cairo city. The results of the conducted study showed that children with ADHD had higher serum Mn levels than controls. The mean Mn serum levels in children with ADHD was (5.5ug/L) compared to (4.1ug/L) in the control group which is significantly higher statistically (P<0.01). Both groups had higher serum Mn levels than the previously recorded reference values (3.3ug/L) by Farias et al. (2010). No significant differences in both males and females concerning serum Mn levels were found (P>0.05).
