Many people who struggle with inattention and hyperactivity notice a link between their symptoms and the amount of time they spend in front of a screen.
Research suggests that brains of people with ADHD show low levels of neurotransmitters. Those are called dopamine, serotonin, epinephrine or norepinephrine and are responsible for transferring information inside the brain. When they’re missing, stimuli can’t be properly filtered. The person gets easily distracted by new stimuli and finds it hard to stick to one thing.
Electronic devices with their action-packed visuals, quick motions, bright colors and sounds grab our attention and send a lot of dopamine to our brains. It’s not surprising that children with ADHD love screen time – it keeps them focused.
Users of one sec confirm that there’s definitely a link between those two:
Almost as soon as I don't spend so much time on the internet, my capabilities slowly come back to me.
[...] the more screen time the worse my adhd symptoms are so reducing it does help a lot even without other treatment.
