New signal in brain to help treat ADHD in children

Changes in the brain of a child suffering from attention deficit/hyperactivity disorder (ADHD) has been identified that can help doctors diagnose the condition affecting 3%-5 % of all schoolgoing children in India.

There is no single test capable of diagnosing a child with the disorder. Consequently, difficult children are often incorrectly labelled with ADHD, while others with the disorder remain undiagnosed.

Using functional magnetic resonance imaging (fMRI), researchers have identified abnormalities in brains of children with ADHD that will serve as a biomarker for the disorder, according to a study presented at the annual meeting of the Radiological Society of North America ( RSNA) here. ADHD is one of the most common childhood disorders in India. Symptoms, which may continue into adulthood, include inattention, hyperactivity and impulsivity.

"Diagnosing ADHD is very difficult because of its wide variety of behavioural symptoms," said lead researcher Xiaobo Li, assistant professor of radiology at Albert Einstein College of Medicine in NY. "Establishing a reliable imaging biomarker of ADHD would be a major contribution to the field," she said.
