Increased oxidative stress in children with attention deficit hyperactivity disorder
Open accessAbstract
OBJECTIVES: The purpose of this study was to investigate oxidative stress in children with attention deficit hyperactivity disorder (ADHD). METHODS: Total oxidant status (TOS), total antioxidant status (TAS), paraxonase-1 (PON-1) and arylesterase (ARE) activity were measured in 76 children (44 boys, 32 girls) diagnosed with ADHD according to the DSM-IV and 78 healthy children (46 boys, 32 girls). RESULTS: Age and sex were similar between the groups (P > 0.05). TOS and the oxidative stress index (OSI) were higher in the patient group than the control group (P < 0.001). PON-1 (P = 0.002), ARE (P = 0.010) activity and TAS (P < 0.001) were lower in the patient group than the control group. DISCUSSION: We found decreased PON-1, ARE activity and TAS, and increased TOS and OSI in children with ADHD. Our study showed that there is significantly increased oxidative stress in children with ADHD.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
