Typical ADHD Behaviors

ADHD Symptoms You Won’t Find in the DSM

The DSM-5 is an essential resource used by clinicians to diagnose and treat ADHD, but experts and ADDitude readers say symptoms are missing, making it increasingly incomplete and even inaccurate.

The American Psychiatric Association’s Diagnostic and Statistical Manual is the enduring authority for healthcare providers who diagnose and treat mental health conditions. Its origins date back to the 1800s1 and, though it continues to serve an important role for patients and clinicians, the DSM is not without significant problems. In the context of ADHD, “the DSM simply does not describe ADHD as the rest of us experience it,” said William Dodson, M.D., in an article outlining the diagnostic symptoms that are missing.

Emotion dysregulation, which research has shown to be a fundamental component of ADHD,2, 3 is one such symptom. Another is gender differences, particularly in females who tend to mask or internalize their symptoms.4 “There’s some research on whether there might be a completely different presentation [of ADHD], at least in females, with a different time of onset and a different level of severity,” said Dave Anderson, Ph.D., in a recent ADDitude webinar on understanding the evolution of ADHD.

If you could add any symptom to the DSM diagnostic criteria for ADHD, what would it be? The answers we received from ADDitude readers included many familiar ADHD behaviors like rumination, daydreaming, time blindness, insomnia, sensory sensitivity, anger, and anxiety. Some readers even suggested changing the name entirely.

“‘Attention deficit’ seems to be the exact opposite of my experience,” said Amanda, an ADDitude reader in Utah. “I cannot pull myself away from the things I am interested in! And hyperactivity represents such a small portion of diagnosed individuals (primarily boys younger than 12). It is only one of dozens of significant symptoms that affect the greater population.”

Below, ADDitude readers share the symptoms that they feel are central dimensions of ADHD. What would you choose to add? Tell us in the Comments section, above.

ADHD Symptoms Not in the DSM

I would love to see separate sets of diagnostic criteria for boys, girls, adult men, and adult women, because (generally speaking) ADHD can look quite different in each of those four groups. Yes, there is some overlap, but I don’t think it serves girls or adult men and women to compare them to a single ADHD picture, that of the stereotypical hyperactive young boy. The rest of us know that isn’t the only face of ADHD.” — Jen, Missouri

“I think the biggest thing I would like to see is more of a focus on emotional dysregulation and the intense emotions that you can feel as a symptom of ADHD. This is one of the main ADHD symptoms that I personally struggle with, and it was never recognized. I was misdiagnosed with bipolar as a teenager because my intense emotions were more associated with BD than with ADHD.” — Kate, Florida

I’d make sure that comorbidities are noted more directly with the DSM diagnosis of ADHD.” — An ADDitude reader

“I believe today’s criteria don’t adequately address adult patients. The word ‘adult’ obliquely refers to patients age 17 and older, but ADHD may manifest differently in older adults. Our prefrontal cortex continues to develop into our mid-20s, does it not? Typically, career advances are met with increased responsibility and visibility, and ADHD traits can become more of an encumbrance further up the corporate ladder (as I learned in my 40s and 50s). Clinicians would likely benefit from a subset of criteria for adults 25 and older.” — Greg, Ohio

“Feeling like you have multiple thoughts at once; thinking spherically as opposed to linearly.” — Sunshine, Colorado

“Apparently, sleep issues are a telltale sign [of ADHD] for young children, yet I read every sleep training book I could get my hands on when [my daughter] was a baby, and not one of them mentioned [ADHD]. I didn’t learn this until she was in high school, which I feel is not just criminal negligence by so-called sleep experts but a huge disservice to parents and to kids with ADHD who could be assessed earlier.” — Kelly, California

The emotional regulation symptoms of ADHD are sorely lacking.” — An ADDitude reader

“The social impacts of ADHD and how it impacts the ability to maintain friendships is a big hallmark for me. In general, I wish the DSM had a great deal more nuance, especially when it comes to identifying ADHD in girls and adults.” — LeAnn, Wisconsin

“I would differentiate between symptoms that boys have versus symptoms that girls have.” — Tracy, New York

“Anything about sensory challenges. To me, this is actually what ADHD is all about: difficulty blocking out sensory input. ADHD encompasses the challenges and ways people deal with sensory overwhelm. The fact that the DSM — and as a result, many practitioners — don’t understand this is so frustrating. Without this understanding, they are missing so many people who are probably unable to get support.” — Katie, Maryland

Communication lapses: The tendency [for my son] to think that he communicated something verbally because he already thought it in his mind. We’ve had many incidents where family dynamics were impacted by communication lapses. From his point of view, the communication happened even though nothing verbal was spoken, so the other person wasn’t in the know. This also happens with my spouse (who was diagnosed at 52 after our son).” — Julieann, Ohio

Clumsiness — anecdotally, this is very common among ADHDers, even being accident-prone. I see this a lot in the chat rooms I frequent for ADHDers.” — Diane, New Hampshire

“If it is not already in there, I believe the aspect of emotional dysregulation and/or rejection sensitivity dysphoria is such a huge component of ADHD that gets so very little attention – especially when it comes to treatment for younger children. But even for me as an adult, when I learned about the term RSD and what it meant, it stopped me in my tracks and totally changed the way I looked at my ADHD.” — Geoff, Rhode Island

I would add criteria under affective disorders relating to anxiety and personality disorders like BPD/OCD to ensure it isn’t ADHD before making one of those other diagnoses.” — Greg, Canada

Include not recalling content in a conversation literally right after or immediately after the information is shared. I think my kids are ready to kill me; they have told me that they purposefully don’t talk with me that much because I never remember. It’s awful.” — Shannon, Ohio

“I would make sure that something like survivalist, problem-solver, or despiser of mundane tasks were all in there!” — Blythe, Oklahoma

A ‘constant state of overwhelm’ would be one. Or ‘takes tons of effort just to exist.’” — Natalie, Pennsylvania
