Attention deficit hyperactivity disorder is linked to delayed brain development

ADHD A'Brain Disorder, Not Just Bad Behaviour Study

The study re-examined data collected at 23 worldwide research sites, involving the brain scans of around 3,200 people and found that certain regions were smaller in people with ADHD, although these variations were less in adulthood.

Nevertheless, these did point to a number of brain differences in ADHD.

They analyzed MRI data from 1,713 people with ADHD and 1,529 controls ranging in age from 4 to 63 years.

"These differences are very small - in the range of a few percent - so the unprecedented size of our study was crucial to help identify these", Dr. Hoogman said. Researchers knew that this brain area is involved in recognizing emotional stimuli and regulating emotions.

The amygdala had the greatest volume reduction, which the researchers thought was telling because of the extent of emotional problems that come with the disorder.

Available vaccines are formulated differently each year-based on the strains of flu that are expected to circulate. People who are at a higher risk for complications from the flu are especially encouraged to get their flu shot.

The five areas affected were the caudate nucleus, putamen, nucleus accumbens, amygdala and hippocampus.

The researchers also took into account whether the participants were taking, or had ever taken, medication to treat ADHD (such as Ritalin), but this appeared to have no effect on the findings.

The volume overall was smaller in people diagnosed with ADHD, as were five of the brain regions, the team said.

Martine Hoogman, a geneticist at Radboud University in the Netherlands and also the first author of the study, claimed that the amygdala is a brain structure which was not known to be involved in the evolution of ADHD. The other regions with decreased volume were the caudate nucleus (which plays a role in goal-directed action), the putamen (linked to learning and responding to stimuli), the nucleus acumbens (rewards and motivation), and the hippocampus (which helps form memories).

Despite the large numbers of participants of all ages, the study was not created to investigate how ADHD might develop over a person's lifetime.

The expectation is that second-year player Laremy Tunsil will take over the starting left OT job. He hasn't played a full season since 2011, which is also the only full season of his career.

The differences in brain size were particularly prominent in the children and less obvious in the adults with ADHD, note the authors, who suggest that their findings show that ADHD is a brain disorder characterized by delayed development in several brain regions. He has suggested that ADHD could be classified as a brain disorder based on the study.

The study ruled out the possibility that the brain changes were caused by ADHD drugs.

'This is a disorder of the brain just like clinical depression, schizophrenia and bipolar disorder - also associated with abnormal brain volumes. According to them, their findings may aid in improving the understanding of ADHD, challenging beliefs about the condition to do away with labels attached to it.

The research was conducted by ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis), an ADHD-working group which brings together scientists around the world and from various fields to study the brain.
