Kids with ADHD have some smaller than usual brain regions: study
Kids with attention-deficit hyperactivity disorder (ADHD) have slightly smaller than usual brain regions, a fresh review of ADHD patients’ brain scans revealed.
A team of researchers led by Martine Hoogman of Radboud University in the Netherlands analyzed brain (MRI) scans for more than 3,200 individuals in a total of nine countries in the age group of 4 to 63 years, of whom 1,713 had ADHD.
The study revealed that the brains of children with ADHD were slightly smaller in at least five regions, including those regions that are responsible for controlling emotions, understanding and voluntary movements.
Cambridge University psychiatrist Graham Murray said, “The study confirms that there are structural differences in the brains of people with ADHD, but it doesn't tell us what they mean.”
The researchers reviewed one brain scan per ADHD patient and were surprised to find that there was no effect from medications.
The study, which was funded by the National Institutes of Health, appeared in the Wednesday (Feb. 15th) edition of the journal Lancet Psychiatry.
