Brains Of ADHD Patients Are Found To Be structurally Diverse

Brains of the kids having attention deficit hyperactivity disorder (ADHD) were found to be structurally different compared to the normal ones. The structural differences were found to be due to an elevation in the signals between the sensory and cognitive regions. The noisy signals that are wired between the regions are found to hamper the neural pathways in people with ADHD. The brains of the ADHD patients were found to function differently as the messages sent on certain occasions were erratic. The study published in the journal Molecular Psychiatry showed child diagnosed with ADHD to have no psychiatric comorbidities. Thus, the MRI scans helped create a virtual map of the brain pathways that showed the roadblocks in the neurological highways.

The children having ADHD showed their structure-function coupling in the feeder regions connecting the brain’s hubs with peripheral regions to be lower. The faulty communication between the brain regions was found to be one of the major symptoms of ADHD. In ADHD, it is just like the speaker that does not function properly and results in static sounds that are difficult to differentiate. The medications are the best treatment for ADHD but the latest study can help find new interventions that can help lower the noise created in the brains.

On a parallel note, the Child Mind Institute has reported that in the US in the past 10 years the ADHD rates among the adults are found to have doubled. The percentage of adults diagnosed with ADHD rose from 0.96% in 2016 to 0.43% in 2007. One of the interesting facts is that white adults showed a huge increase from 0.67% to 1.42% compared to the other racial/ethnic groups. In adults, the people having mental illnesses like depression, anxiety, eating disorders, and bipolar disorders were found to, later on, develop ADHD. Thus, the researchers are trying to find why the whites are at a higher risk and working on newer diagnostic tools.
