After studying about 55,000 individuals, a team of scientists discovered that Attention Deficit Hyperactivity Disorder is not as simple as we believed. According to their recent study, there are some genetic variants that boost the risks of ADHD, a condition that, reportedly, affects about 2.5% of adults and about 5% of children worldwide.

“We know that it is highly heritable. Among all the causes that can lead to ADHD, genetic factors account for between 70% and 80%,” explained Professor Anders Borglum from the Aarhus University in Denmark, and the new study’s co-author.

Finding the genetic variants involved in higher risks of ADHD was challenging, according to the scientists involved in the research. That because there are man genes that trigger Attention Deficit Hyperactivity Disorder and each of them is linked to just a tiny risk factor.

After analyzing about 55,000 people, out of which approximately 22,000 suffered from ADHD, the scientists identified 12 particular regions in the genome where changes increase the risk of ADHD.

“We are extremely excited about these findings we have been looking for this for ages. Those 12 regions are just representing the tip of the iceberg,” added Anders Borglum.

According to the study, ADHD an “extreme expression” of genetic variants found throughout the population.

“We have only officially diagnosed the tip of the iceberg of individuals globally with ADHD, and further gene research is highly likely to uncover more variations that may also be responsible,” said Michelle Beckett, the chief executive of the charity ADHD Action.

“ADHD faces incredible stigma and discrimination and denialism,” and was often thought to be an excuse for poor behavior, despite the impact the condition could have on an individual’s education, health and work,” explained Beckett. “This study almost gives us validation, if you like, in the eyes of the people on the street and also the popular press,” she added.
