Attention deficit hyperactivity disorder (ADHD) is a condition characterized by over-activity, impulsivity and a short attention span.
According to the World Health Organization, one in 20 children are affected by ADHD.
A new study has found that children who 'grow out' of attention deficit hyperactivity disorder (ADHD) have higher IQs than those who do not.
Scientists at King's College London analyzed the progress of a group of 110 kids with ADHD and conducted a range of tests to assess their brain activity and thinking skills.
The results showed that those children who grew out of the disorder performed better in tests measuring attention, levels of drowsiness and reaction time. The children also had higher Intelligence Quotient (IQ) scores than ADHD 'persisters'.
Dr. Jonna Kuntsi, from the Institute of Psychiatry, Psychology & Neuroscience at King's College London, said that the study shows the differences in brain activity and cognitive function between individuals who grow out of their ADHD and those whose disorder continues into adolescence and adulthood.
"These findings will guide the development of interventions for ADHD persisters, such as cognitive training and neurofeedback, that directly target those aspects of cognition and brain activity that are linked to ADHD improving over time," Dr. Kuntsi said.
The study was published in the British Journal of Psychiatry.
