The cause of ADHD is still unclear. It is known that there is a deviation in the functioning of the brain. Research has shown that the size of the brain in humans with ADHD is about 3 to 4 percent less than in people who do not have ADHD. These include areas in the right-hand half, where the organization and concentration are stimulated. Not only is this area less large, it also shows less activity.
The role of heredity in this attention disorder
Most studies show that there is inheritance. Three quarters of all ADHD adults also have children with ADHD. Research has shown that ADHD is seen as neurobiological disorder, and not as learned behavior. Most studies focus on the relationship between genes and the environment. It is assumed that a particular gene will only have a negative effect if there is a risky environment at the same time, such as problematic relationships with others, profound events, poor nutrition and a difficult delivery. In ADHD this seems to be the case.
Children do not grow up about their condition, something that was thought of in the past. It is more so that the symptoms of ADHD (partly) change. They are usually less hyperactive than during their childhood. Instead of busy behavior, they now show an inner turmoil. In addition, they can better control some symptoms, such as impulsivity and rage attacks. That applies less to the typical phenomenon of insomnia. Many adults continue to suffer from sleep problems. But also of forgetfulness, quickly distracted and regularly come late.
Once child-off, and so on its own, a number of ADHD's have difficulty in standing in a society rich in stimulus and distractions. This can cause emotional problems. Think of depression, failure, negative self-esteem and relationship problems. In some cases, ADHD leads to incomprehension by others.
On the outside it can not be seen that someone is suffering from it. If someone is quickly distracted or chaotic, that can be misinterpreted. As if that person is somewhat odd, asocial or irresponsible. As a result, friendships are difficult to maintain, and changes are often made of jobs.
Problems with the neurotransmitters
To transmit signals and pulses from one nerve to another, our brain makes neurotransmitters. In someone with ADHD, these "neurotransmitters" are well transmitted but poorly received. The receiving nerve cell blocks, as it were, the neurotransmitter and hence the signal on which it is reflected. The result is a hyperactive reuptake of the neurotransmitters and associated impulses. This translates into symptoms such as impulsivity, concentration problems, unrest, mood swings, irritability and hyperactivity behavior.
