ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay interested in tasks they would normally avoid. The drugs even reversed brain patterns linked to sleep deprivation. Researchers say this could complicate ADHD diagnoses if poor sleep is the real underlying problem.

This annoys me. Many articles about ADHD refer only to children with ADHD, not adults. I’m nearly fourty and I still have ADHD now, if I make it to 80 I will still have ADHD, why is it always about kids? It is lifelong not just a childhood thing.
why is it always about kids?
Because there’s still a strong misconception that people “grow out of” ADHD.
Btw, when you’re 80 you won’t have ADHD, you’ll have 80HD!
To examine how stimulants affect the brain, the researchers analyzed resting state functional MRI, or fMRI, data from 5,795 children ages 8 to 11 who took part in the Adolescent Brain Cognitive Development (ABCD) Study. Resting state fMRI measures brain activity when a person is not performing a specific task. The ABCD study is a long term, multisite project following the brain development of more than 11,000 children across the U.S., including a site at WashU Medicine.
It does study adults, we just have to wait
because neurotypicals don’t actually care about how ADHD effects the people with it, just those who interact with them.
I suspect most adults have some coping mechanisms built up so its often harder to separate out the basic problems. Children offer a ‘cleaner’ study, so that is what they focus on.
I have to say my 6 year old has a lot of symptoms. I started giving her melatonin to help her sleep and a lot of the behavioral issues have gotten a lot better.
I’m not trying to say its a cure all, but I was surprised how well it helps her sleep, and how many (I thought) unrelated issues have improved.
Even if it doesn’t bring anything novel having confirmed results is good in science.

Of the many people that have tried to “inform” me about what they feel ADHD actually is. The majority seem to think you just grow out of it. Their lack of knowledge definitely doesn’t stop them from forming opinions.
It’s a complex subject hindered by lack of research and, frankly, a lot of prejudice.
The more I learn, the more I suspect it’s not that “the presentation” of ADHD changes magically as you age, it’s that people who grew up with it are neurologically shaped by having to compensate for so long under adverse conditions.
I recently read about a study attempting to establish a noninvasive treatment that stimulates under-active brain regions in kids to see if it can have a positive long term effect.
In the second phase, a subgroup of children with ADHD participated in a randomized, sham-controlled trial combining cognitive training with transcranial random noise stimulation (tRNS), a painless, non-invasive form of electrical brain stimulation. The researchers targeted frontal brain regions involved in attention and self-control. After ten sessions, children who received active stimulation showed a significant reduction in the atypical brain signal, along with improvements in task performance. Importantly, some of the neural effects persisted 3 weeks after the intervention ended.
Food for thought, eh?
This lines up with my experience more. I never identified well with “you need help focusing, this medication does that and that’s why it helps you”. I have always been able to sit for half a dozen hours on an interesting thing and completely forget to eat or think about anything else. So it doesn’t make much sense to me that I have a focusing issue. I had been explaining my medication as “it takes the minimum level of reward the thing has to provide me for me to continue doing it, and drops it into the floor. So now everything is so rewarding that it doesn’t matter what it is, I can focus like I did with only a few things before”.
The name adhd is misleading… it’s not a deficit of attention but a a deficit of being able to control where to put the attention.
(btw some adhd researchers from switzerland proposed to rename it to “Unusual Management of Informations and Functions”)
This makes a ton of sense seeing as most people with ADHD i’ve talked to/read their perspective is that ADHD fucks with their motivation.
Mine is depression. Absolutely nothing is rewarding because every job in my field is bullshit now. I’m too tired after work to enjoy anything. I’ve awakened tired every day of my life. Adderall is a lifesaver and I seriously would have killed myself if I had to be without it because I literally can’t function.
What exactly is new here?
Their findings suggest that these medications primarily affect brain systems involved in reward and wakefulness rather than the networks traditionally linked to attention.
I’m in my 40s and got diagnosed 2 years ago. One of the first things I learned is that ADHD has to do with dopamine deficit and that the stimulants either slow down the reduction of available dopamine or increase it’s release. And dopamine is a neurotransmitter directly connected with the reward center. And that’s one of the reason our attention changes focus all the time, because we’re looking for something new as the current task doesn’t release dopamine anymore. Yaddayadda you know the drill.
Plus I sleep better when taking meds so I don’t think stimulants work the same way for ADHDers as they do for neurotypicals.
Or is there something I completely missed?
Norepinephrine is another neurotransmitter highly implicated in ADHD.
Quoting from Wikipedia: Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the brain, norepinephrine increases arousal and alertness, promotes vigilance, enhances formation and retrieval of memory, and focuses attention; it also increases restlessness and anxiety.
The trouble of being to regulate wakefulness has been in my personal experience more pronounced than attention jumping around. But that’s likely fairly individual. I wouldn’t be surprised if the inattentive subtype & hyperactive subtype categories we use now were related to balance of these two.
Well it’s a good thing we make our kids get up at the crack of dawn to get to school. /s
It’s so annoying once you realize society intentionally forces children to learn at inopportune times because one of its main jobs is daycare. Doesn’t matter that delaying school by a couple hours would likely (only a correlation at this point) improve kids’ grades and overall well-being, that would mean impacting their parents and their jobs.
