Focus of ADHD should be on attention deficit’

From examination of the Radboudumc, it is shown that the approach of ADHD in the attention deficit than hyperactivity.

ADHD is a combination of your hard to focus, and then press and impulsive behavior. It is remarkable that people very often suffer from a combination of both characteristics. Tom Heskes and his colleagues investigated whether there was a causal relationship. The results of the research published in PLOS ONE.

“You see them very often, but you can’t say that inattentie – attention-deficit – leads to hyperactivity. But neither that hyperactivity leads to inattentie. Just as in the previous example you have here at least a third factor is needed, which can present information about a possible causal relationship.”

Used therefor Heskes the information that the other researchers have provided. Thus, it is known that some genetic variations have a greater chance to ADHD. Just as men are also more likely to suffer from ADHD than women.

“In both cases, our computer algorithms a causal relationship that runs from a lack of attention to the hyperactive, impulsive behavior. And not the other way around,” says Heskes. “In three different, independent data sets, there seems to be no indication that the impulsive, hyperactive behavior, the cause would have difficulty to concentrate, to your attention to focus on something.”


“In the early psychiatric literature was that the causal link also suggested,” says psychiatrist Jan Buitelaar, “but as far as is known, this has never been hard evidence has been found. It is nice that we do with this mathematical approach, now with more certainty about such a causal relationship, you can talk to.”

“For example, it is interesting to investigate whether we for that relationship also has a more neurological underpinnings can be found,” according to Buitelaar.

In addition, it also provides a guideline for therapeutic approaches. “If inattentie indeed the motor is of the impulsive, hyperactive behaviour, then you can the treatment be better to focus on an approach of inattentie than of hyperactivity. This research indicates that the chance is greater that a reduction of inattentie also the hyperactivity decreases, then if you go the other way try it.”
