Is It ADHD Perseveration or Hyperfocus?

November 30, 2017 Noelle Matteson

People with ADHD sometimes exhibit signs of perseveration, which is sometimes confused with hyperfocus. Read more to learn about perseveration and ADHD.

I first heard the term "perseveration" in a lecture by psychologist Russell Barkley about attention-deficit/hyperactivity disorder (ADHD) and hyperfocus.1 People with ADHD struggle with boredom, but they can often focus on things they enjoy. In fact, they can focus too much, obsessing over one thing and ignoring other subjects and tasks. Barkley suggests that ADHDers do not hyperfocus, as people with autism do, but perseverate. He defines perseveration as the inability to stop doing an activity at an appropriate time.

ADHD, Perseveration, and Hyperfocus

Many ADHDers describe their ability to hyperfocus as a superpower, but Barkley states that perseveration in ADHD is never an asset. I do not necessarily agree with him because people with ADHD can create, accomplish, and discover great things due to their obsessions. However, it is true that hyperfocusing can create burnout and make people less productive than if they were able to approach tasks in a more balanced manner.

Discussing Perseveration and ADHD

Barkley's comment got me thinking about what perseveration actually is and how it applies to those with and without ADHD. In the video, I talk about the definition of perseveration and some of its symptoms (such as repeating the same gesture, behavior, phrase, or word).

I have practiced general psychiatry for 27 years. I have had ADHD all my life but only given a diagnosis at age 44. I had always had the perceptive that life is just meant to be a struggle and I became very good at compensating for my distractibility, procrastinating, disorganization etc. I learned to figure out things for myself. I felt so relieved to finally learn about the diagnosis. Now 20 yrs later I've learned about RSD and perseveration and at age 64 I realize that this is exactly what I've always suffered from but never knew how relatively common it is. After such a long journey I finally understand more precisely the operation of my unique brain.

The difficulty I have is being constantly interrupted by other thoughts or ideas that I cannot get to stop when I need to be working on another task. Except with excessive internal dialog, reminding me that I am off task. Which is quite exhausting.

I have a feeling we ADHD people just feel like we are hyperfocusing when we are really just focusing like a non ADHD person. But to us, those moments are fewer and farther between, so it's like "wow! I'm hardcore hyperfocusing". Hyperfocus implies an ability to do it at will. Which I cannot. But when I can stay on task for many hours, on something I am SUPPOSED to be doing, it is magical, TO ME. But would be normal for a non ADHD person. But, if I'm hyperfocusing, UNwillingly, , it is not a superpower. It is stuck. It is perseveration. ADHD is not a super power. I think people call it that because there is shame is being perceived as less intelligent. Which is certainly why I do not tell my employer about it. But we need to stop calling it a superpower. I'm relatively happy and successful DESPITE my ADHD. Not because of it. Russel Barkley is on point. I cried listening to his talks on youtube and finally went in for a diagnosis at 33.

Dr. Barkley made a big difference to me too. Although, I don’t exactly agree with the idea that those of us with ADD or ADHD are probably just focusing like people who are not neurodivergent when we perseverate. I learn so much about a subject that I focus on, that others not like me, and often quite intelligent, wonder how I know so much about it. Well I believe it’s because I care about it and that’s what makes me focus. I know really smart people that can really focus on things and are not neurodivergent, but they don’t care about what they are focusing on. Because they don’t care about it and understating comes so easy to them, they just study a subject without any emotional attachment and they just learn the basics and never delve into the finer more nuanced aspects of that subject. It seems to me that we become passionate about what we perseverate on while others just focus on things to get them done so they can move on. Of course we see it as a super power! Because we are excited about what we just learned!

Hi I just was In Ptsd treatment and was told I am not easily redirected at times when upset and will continue preserving on the topic. As a child I was diagnosed as "hyper". I found this To make sense

Hi! My 8 year old son get “stuck” on topics that change every few months or so....last month it was Pokémon, then nerf guns, then geodes and now we are transitioning into dinosaurs. Although he was diagnosed with ADHD in kinder, this behavior has been going on for years and I never really knew it was a “thing”. Thank you for putting into words what I’ve been seeing. Hoping to get him some help before it hinders him socially as he gets older.

Thank you for sharing, I'm glad this helps! There's still so much to be learned about the condition.

r perseveration - I discovered this site last evening. I have watched your video and it is so helpful to me. My primary therapist has observed and spoken with me about my becoming “obsessed” wiith one thought, idea, or subject for extensively long periods of time. The first time she noticed was as I was reading a book - Smilla’s Sense of Snow. I began to develop a geographical interest in Nuuk, Greenland. I was legally prepared to change my name to Smilla Jasperson. It was really bizarre. Other obsessions were about The Humane Society of the United States and CARE. I adopted a dog and we were together for 5 yrs until I became so physically ill that it was negatively effecting her needs as a dog. Thank you for sharing this info. I’m going to share it with my therapist.

I'm glad it was helpful. I think a lot of symptoms of ADHD overlap with other conditions, like OCD. I hope everything goes OK, and thank you for your comment!

I can totally relate. There was a time I totally had body dysmorphic disorder traits as I became obsessed with a body part. And a number of other unrelated, passing "obsessions". The interest are fine and dandy until they affect our lives because we cannot resist the urge to put them above our true priorities, leading to anxiety/depression for failing to do what we know we need to do. uhg. All because of ADHD induced perseveration as the cause.
