Study suggests ADHD may have been an evolutionary advantage health

Attention Deficit Hyperactivity Disorder (ADHD) tends to be viewed as a negative thing. Symptoms, which include hyperactivity, impulsivity, or inattention, are considered impairment. However, recent studies suggest that people with ADHD tend to have more… Creative, dynamic, and socially and emotionally competentIn addition to possessing great cognitive skills.

👉 Now, new research from the University of Pennsylvania seeks to trace the origins of ADHD and suggests that the disorder will… An important part of evolution. Researchers believe that this disorder evolved as an adaptive survival strategy for our ancestors.

In the study, published in the Journal of the Royal Society, researchers analyzed data from 457 adults, 206 of whom said they had strong symptoms of ADHD.

In a virtual game, participants had the task of collecting as many wild fruits as possible in a certain period of time. Hey The game forced participants to make decisions, e.g: Do I continue harvesting in the same place where the fruits are running out or do I change the location to explore a new bush? The last option costs precious seconds.

Participants with ADHD tended to move faster and spend less time in one bush. Thus, they reaped more fruits than the other group without showing symptoms of the disorder. The latter, in turn, tended to spend more time on the same bush, hoping to improve the harvest.

The researchers were surprised by these results, as they initially thought that rapidly changing shrubs could lead to lower yields. “But no More severe ADHD symptoms lead to a higher rate of reward and better performance“, according to Barak.

ADHD as a survival strategy

The tactic used by the ADHD group has advantages: Avoids exploiting resources in one place At the same time, Expands exploration to new areas. A strategy that may have been vital to the survival of a hunter-gatherer society in the past.

Other studies also support the evolutionary advantage hypothesis. They have proven that a nomadic lifestyle is associated with genetic mutations that play a role in ADHD.

This may be a plausible explanation for the current prevalence of ADHD. But with the difference that Traits that used to work well in harvesting food are no longer useful in today's society. Especially when resources are no longer so scarce.

Dopamine, a neurotransmitter in the brain responsible for the sensation of reward, is broken down more quickly in people with ADHD than in those without the disorder.

The constant search for an important neurotransmitter can cause people with ADHD to constantly switch between different tasks without actually completing them.

❗ However, the researchers stress the need for further investigation, as the study has some limitations. For example, ADHD symptoms were based on participants' self-assessments, without a medical report.

In the next phase, the study will be conducted on patients who have been clinically diagnosed with ADHD. The virtual harvest will move to real fields, which will require more effort from participants.
