Oxidative stress is one of the common causes in etiopathogenesis of attention deficit hyperactivity disorder (ADHD). Hence, the salivary levels of protein thiols, ceruloplasmin, magnesium and pseudocholinesterase were estimated in children with ADHD. The symptoms of ADHD were identified using Conner's rating and DSM IV criteria. Saliva was collected and assessed for the levels of protein thiols, ceruloplasmin, magnesium and pseudocholinesterase, spectrophotometrically. It was also checked for pH and the flow rate was noted down. There was a significant increase (P < 0.001) in the salivary protein thiols and pseudocholinesterase levels in ADHD children when compared to controls. Ceruloplasmin levels did not show any significant change. Magnesium levels were significantly decreased (P < 0.001) in cases when compared to controls. Further, a receiver operating characteristic curve for validity of the biochemical parameters in saliva of ADHD children indicated a sensitivity and specificity above 90% for protein thiols and magnesium values. Our study shows that protein thiols, magnesium, and pseudocholinesterase might have a role in the pathogenesis of ADHD and saliva can be effectively used as a non-invasive tool for evaluation of such children.
