Mark's Daily Apple Wednesday, July 13, 2022 11:00 AM Attention Deficit Hyperactive Disorder is a common issue. While rates seem to have leveled off in the past decade, they haven't decreased—and they're still higher than historical norms. As with any health condition that seem to "appear" all of sudden across society, we have to wonder if something about the modern world is triggering a rise in ADHD. Plenty has been written about diet and other relevant environmental inputs that have changed in recent decades. What about another, arguably more recent shift—technology? Does technology increase or worsen ADHD? To answer that, we have to go back. We have to look at Attention Deficit Hyperactive Disorder in an ancestral context. Living with ADHD Then and Now A 2008 study found that among two rural tribes of Kenya—one nomadic, one settled in villages—those with genetic signatures of ADHD living in the nomadic (and more ancestrally aligned) group were more successful, having higher body weights and more lean mass (muscle). Their genetic drive actually improved their ability to contribute to the group and succeed in the nomadic, hunting, and foraging environment, whereas in the settled group those with ADHD signatures were lighter and less nourished. What is this genetic signature? It's a variant of the dopamine 4 receptor—DRD4-7R—that dulls the intracellular response to dopamine in carriers. What's dopamine have to do with ADHD? Dopamine is often called the pleasure neurotransmitter, but it's really the motivation neurotransmitter. Dopamine is a wanting chemical that compels us to seek, do, move, to make things happen. To do so, it triggers reward pathways in the brain using other chemicals. When you "win" at anything, you get a hit of dopamine. The hit of dopamine is intended to perpetuate the action that got you the victory. It's supposed to keep you pushing forward to greater wins and greater rewards despite turmoil and difficulty. For instance, dopamine raises the fatigue threshold during intense exercise. It actually makes you stronger and more resistant to suffering and hard times, and not just in exercise but in business, hobbies, everything that requires effort. This is where ADHD comes in. If dopamine isn't as "effective" in a person with ADHD, they have trouble pushing through the drudgery and the early tough moments to see something through, whether it's studying, writing a paper, or following through with an idea for a business. The genetic signature in question increases a person's drive toward novelty, thrill-seeking, and even food and substance abuse issues. In other words, it pushes them toward "easier wins." This drive makes sense in a hunting and gathering setting where you have to be willing to expose yourself to dangerous situations, explore new locations, and relentlessly pursue food and sustenance. There are a lot of moving parts out in the wilderness, and the tasks you have before you are acutely stressful and intense. They're closer to video games than studying for an exam. That's why the Kenyan nomads with ADHD signatures did so well and the Kenyan villagers with ADHD signatures did not: the nomadic environment is set … Continue reading "Is Technology Causing ADHD?"
