Children with ADHD have smaller brains, says new study

According to a new study, children with attention deficit hyperactivity disorder (ADHD) have smaller brains. Previous studies have linked ADHD to genetics, along with environmental and developmental factors. Researchers found out that children with ADHD have a smaller brain size after checking multiple regions of the cerebral cortex, including the frontal, temporal and parietal lobes. These are the main areas of the brain that controls the behaviour of a person.

The research was conducted on kids between the age group of 4 to 5 years. Half of these kids had ADHD and were not under any medication. They concluded the study after closely examining brains of the kids through MRI scan, cognitive and behavioural measures.

Lead author of the study E Mark Mahon said that this new study proves that ADHD is a biological condition. Through this new study, researchers want to find out more about ADHD and how children can be identified of this risk.

Researchers from the Kennedy Krieger Institute published this study in the e Journal of the International Neuropsychological Society.
