Scientists continue to be surprised by the findings of long-term ADHD studies.
Our understanding of ADHD has come a long way in just a few short years. Though it wasn't even formally recognized as a medical condition until the 1960s, by the time the 90s rolled around, diagnoses and stimulant prescriptions were extremely prevalent. (Raise your hand if you grew up in the era of "Anyone who struggles in school gets Ritalin!") Today, diagnoses and treatment are a lot more thoughtful and individualized, and there are more options for treatment and therapy including but not limited to stimulants like the well-known Ritalin. Even with all these advancements, though, we still have more to learn.
A new long-term study published in the Journal of Clinical Psychiatry has proven to be an excellent next step in getting a better understanding of the disorder, showing that a lot of what's commonly believed or assumed about ADHD is incomplete or just flat-out wrong.
Researchers studied 483 participants who were diagnosed with ADHD in childhood and continued to assess them for a period of 16 years. The study's authors wanted to get a sense of how ADHD symptoms might change over time.
What the researchers found surprised them. In most participants, symptoms of ADHD fluctuated greatly over the years rather than staying consistent. What surprised them even more were the environmental factors that seemed to play a role in those fluctuations.

Researchers expected that greater life demands—like more responsibility at work, a heavier workload at school, major life changes, etc.—would exacerbate ADHD symptoms. What they found was the opposite.
It makes sense that a person that struggles with inattention or hyperactivity might have more trouble focusing when they have more "going on" and more distractions to pull them in different directions. It was a huge surprise to the researchers that, actually, people's ADHD symptoms seemed to ease up when life got hectic.
“We expected the relationship between environmental demands and ADHD symptoms to be the opposite of what we found,” study author, professor, and clinical psychologist Margaret H. Sibley explained. “We hypothesized that when life demands and responsibilities increased, this might exacerbate people’s ADHD, making it more severe. In fact, it was the opposite. The higher the demands and responsibilities one was experiencing, the milder their ADHD.”

I have a 4-year-old with ADHD and the findings totally track for me based on what I've witnessed in our own life.
We find it's actually easier to be in perpetual motion sometimes—out running errands, doing activities, visiting friends and family—versus staying put too long. When we're just relaxing at home, that's when she tends to start bouncing off the walls! Her ADHD tendencies come out strong in these quiet periods, including what we sometimes playfully refer to as her "hoarding" dozens of coloring sheets or surrounding herself in giant piles of toys, blankets, and stuffed animals; thereby making a huge mess in the house.
Doing nothing or doing very little is not often a restful state for people with ADHD. Typically, people with ADHD experience more background noise than neurotypical brains—so a quiet, seemingly restful environment can sometimes amplify racing thoughts, negative self-talk, and impulsive behavior versus dampening it. You know how kids sometimes act out in school not because they're not smart, but because the material is actually too easy for them and they're bored? Something similar is at play in both of these scenarios.
Of course, as always in science, you have to be careful assuming causation from the findings.

It's important to note that the results of the study don't definitively prove that being busy causes a decrease in ADHD symptoms.
“This might mean that people with ADHD perform their best in more demanding environments (perhaps environments that have stronger immediate consequences, like needing to put food on the table for a family or pay rent monthly). It also might mean that people with ADHD take more on their plate when their symptoms are relatively at bay," Sibley says. Either way, the correlation is certainly strong and worthy of more study.
In the meantime, the study's authors think the results could be viewed in a hopeful light for people just learning to manage their ADHD. “If you’re a doctor talking with a patient who is first getting diagnosed with ADHD, it’s a huge help for that person to hear the message that, ‘You’re going to have good years and not-so-good years, but things can go really well for you if you can get the right factors in place,'” Sibley said. As a parent, I can imagine how reassuring that would have been to hear early on in our own process.

With ADHD diagnoses on the rise, more and more research is being conducted. For example, a recent long-term study out of Sweden was just published linking use of ADHD medication with a reduction in traffic crashes, general injuries, and criminal behavior. That's a strong argument for continuing to hone in on accurate diagnoses and treatment for people who need it, as it clearly benefits society as a whole when done properly!
We're learning more and more about what the factors that affect positive ADHD outcomes are—what might exacerbate symptoms and what types of things can help—and we're starting to get a clearer picture of how people can manage this challenging disorder.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
