Digital Dementia & Brainrot: Risks & Prevention

by Archynetys Health Desk

Al langer baart het Erik Scherder (73), hoogleraar klinische neuropsychologie aan de VU, zorgen dat kinderen en volwassen van 9 tot 18 uur, en soms nog langer, vrijwel ononderbroken achter een scherm zitten. „Dat is echt kwalijk. We zagen dat al gebeuren met de komst van de smartphone en sociale media, maar door AI gaan we nog veel meer tijd doorbrengen achter het scherm.”

Welke mechanismen zorgen ervoor dat we steeds meer tijd achter een beeldscherm doorbrengen?

„De aandacht van kinderen en jongeren wordt meestal opgeslokt door sociale media zoals TikTok en Snapchat. Daarnaast speelt gamificatie een rol. Vrijwel alles wat ze zien wordt gepresenteerd als een spel of een challenge. Dat speelt ook bij reclame-uitingen. Zo’n 70 procent van wat ze zien is gemaakt met kunstmatige intelligentie. Al die uitingen zorgen ervoor dat ze meer en meer het scherm worden ‘ingetrokken’ en steeds minder lichamelijk en geestelijk actief zijn. Het worden digitale zombies.

Een smartphone geeft doorlopend beloningen aan de hersenen. Elke keer een kort, grappig filmpje op TikTok of een short op YouTube houdt 30 seconden de aandacht vast. En dan komt de volgende. De ene gekkigheid na de andere. Dat geeft steeds weer een goed gevoel. En het kost nauwelijks energie; je hoeft niet eens te zoeken naar een volgend filmpje. Je kunt zo uren en uren blijven scrollen. Het is eindeloos en er zit geen rem op.”

Waar leidt dat surfgedrag toe?

„Tot brainrot of hersenrot. Als je moe en futloos urenlang het ene na het andere filmpje zit te kijken, ontwikkel je een gevoel van afstomping, mist in je hoofd en een gevoel dat je nergens meer zin in hebt. Je voelt je ontevreden vanwege de verspilde tijd. Maar ook stress, angst en een gevoel van doelloosheid. De taalontwikkeling blijft achter en de ontwikkeling van empathie en motivatie loopt schade op.”

Is er what to do on Brainrot?

„Houd het simpel. Stel de 20-20-2-regel in voor kinderen: laat ze na 20 minuten achter een scherm 20 seconden naar buiten staren tegen bijziendheid en vervolgens 2 uur buiten spelen. Voor pubers, bij wie de hersenontwikkeling in volle gang is, geldt de 20-20-20-regel om brainrot te voorkomen: na 20 minuten schermtijd 20 seconden naar buiten staren naar iets dat 20 voet, oftewel 6 meter, bij hen vandaan staat. Ga niet doelloos scrollen, maar richt je Attention on one thing and challenge your brain.

What about adults?

“With them, the” Law of the least spiritual effort “also plays an important role. You can have AI jobs performed. That is fine if you are challenged. I am not taking care of any care about the cognitive efforts of AI programmers. But practice also teaches that most people choose to make the job, which is usually a good result. Lower then the argument is often: so I am worried. ”

Anyone who hangs too much behind a screen becomes gloomy, more anxious and impulsive ”

Erik Scherder, professor VU

Why?

“Because AI does the work, the brain is structurally underperforming – that is called” Underuse “. The networks that you make when you think also check our emotions. Anyone who hangs too much behind a screen weakens this mechanism. You have less control over your emotions. You get gloomy, anxious and impulsive.

Are we also getting stupid?

„Wat je niet gebruikt, verdwijnt op den duur. Dat geldt voor spiermassa, maar ook voor de hersenen. Volgens sommige wetenschappers verdwijnen bepaalde hersenverbindingen als je die niet gebruikt. Het geheugen verslechtert, terwijl een student op zijn tentamen niet op zijn telefoon of AI kan vertrouwen. Je verliest sociale vaardigheden. De gerichte concentratie neemt af, terwijl begrijpen wat je leest essentieel is om het ook te onthouden. En we surfen ons suf, maar ervaren weinig diepgang. As a result, the critical thinking capacity is reduced.

These are all symptoms of dementia. Mind you, it is not dementia, but it is the symptoms of dementia that occur among young people. We also call this “digital dementia“. “

Why don’t we notice that?

“I think everyone knows this, but the positive feeling of convenience dominates by AI. We love simple and fast. That is addictive. And it is easy in the short term, but it turns against us in the long term. I use AI as an abbreviation of” decreasing intelligence. “

Mental effort can postpone the moment that dementia will occur. People who spend a lot of time scrolling behind a screen build up less cognitive reserves, so that they can rather show symptoms of old -age diseases, such as Alzheimer’s disease. ”

How hard is that relationship between cognitive inactivity and decreasing intelligence?

“The digitization used to make better use of our capacities. Now you see the opposite event. We are leaving the thinking more and more to AI, and our brain capacities do not use insufficient. This connection is not rock hard, but there seems to be some connection between increasing technical development and a decrease in the average IQ.”

Interesting is that spatial insight even increases, but that language skills decrease; The net effect is a possible decrease in the IQ. Mind you, I only base myself in my book on scientific research. “

Physical inactivity is another risk factor lurking with a lot of screen use. How bad is that?

“Physical and cognitive activity influences each other. If you move more? Then your heart will beat faster and the blood flow of the brain will get better.

The metabolism of the brain goes up: the activity of the neurotrophins – the nutrients of the neurotransmitters, such as dopamine – also goes up.

“The current version of Homo Sapiens mainly moves the fingertips”

Many areas in the brain are involved in both motor skills and thinking. For example the hippocampus. The area is known for its role in memory, but also plays an important role in navigating. And that makes sense: if you move through space, your brain is active to navigate. ”

What are the consequences of that?

“Unfortunately, we also have to deal with the” Law of the least physical exertion “. We are also more likely to be lazy than tired. The current version of Homo Sapiens mainly moves the fingertips, watch TV and surfs online. The robot vacuums or mowing the grass. The dishwasher also prevents our physical and chronic. an increased chance of dementia. ”

Can the tide be reversed?

“We have to move. You really don’t necessarily have to go to the gym, if you only exercise moderately intensively. So go to the windows, vacuum the house and mow the grass. Let the children cycle to school on a normal bike. And go for at least 20 minutes every day.”

Why is walking so good for a person?

“That is close to us, it is accessible. We get out of the door and we walk. Even someone with a walker can still walk; and that is a best effort. Scientific research shows that around 7000 steps a day gives the greatest health gain.

Every step counts: more is always better. That was also the idea behind the Ommetjes app that I launched during the Coronaper period. ”

“After a day of hard work, parents are already happy that the children are sweet with an iPad”

Erik Scherder, professor VU

We also have to read more; Preferably from paper. But how do you get a teenager on a book?

“This question parents ask me the most. When you get home from a day of hard work, you are often happy that the offspring is sweet on the couch with an iPad. Parents let it happen, because they do not have the energy to do something with them. But they have to set limits: so far and not to read. If you want to put children, reading must be fun.

The parents and the school are with the child and the adolescent for most of the day. The task lies with them to ensure the highest possible cognitive reserve of their child by challenging the brain. The higher the cognitive reserve, the more resilience they have for the rest of their lives. Who doesn’t want that now? “

And how do you get them off the bank?

“Everyone can register for the thirty -day challenge, which runs from 1 to 30 October at the Brain Foundation, to challenge themselves mentally and physically. What children and others like from the activities can continue to do. More than 2000 people have already registered for it.”
