For the first time, scientists have successfully identified 12 genetic variants that significantly increase the risk of developing attention deficit and hyperactivity disorder affecting 5% of children. And not only. Experts have also found genes responsible for impulsivity even in healthy people. But let's see the study in detail.
Revolutionary discovery. We already know that our genes play a very important role in the development of mental disorders, especially with regard to deficit disorder of attention and hyperactivity, genetic factors increasing the risk of 75% . The experts compared genome-wide data from 20,000 people with ADHD and 35,000 healthy people to understand the source of this risk in our DNA. particular genetic variant risk more than those that do not have this variant.
This is the first time The experts finally explain that for the first time, thanks to the huge amount of data badyzed, it has been possible to determine at what points of the genome the risk of developing ADHD is integrated and how these genes influence our behavior.
How they influence behavior Experts explain that some of the identified genes influence how brain cells communicate with each other, while others play a fundamental role in cognitive functions, such as language and learning. In general, the study shows that the risk of these variants determines the extent to which these genes are expressed in our brain.
The gene of impulsivity. Among the identified genes, experts say they have found the one linked to impulsivity that usually affects the behavior of healthy people, making them more or less impulsive.
