Adults Diagnosed with ADHD Later in Life: Part 3

When ADHD Hides Behind Discipline

For many years, ADHD was viewed primarily as a condition affecting young boys who were constantly moving, interrupting class, or acting impulsively. Those behaviors became the stereotype, making it easy to overlook people whose ADHD looked very different.

In the first two parts of this series, I shared the stories of women whose ADHD wasn't recognized until adulthood. But late ADHD diagnosis isn't limited to women. Many men also spend years relying on discipline, structure, and long work hours to compensate for ADHD symptoms. From the outside, they appear successful and in control. What others don't see is the amount of effort it takes to keep everything together.

Dustin, an actuary, is one of those people. He wasn't diagnosed with ADHD until he was 45 years old. His story reinforces something I often tell patients: managing adult ADHD isn't about finding one solution. It's about building a combination of strategies that support executive functioning, emotional regulation, and daily life.

Here's Dustin's story.

At what age were you diagnosed with ADHD?

“I was 45 years old.”

Why do you think it took so long to be diagnosed with ADHD?

“I think there were a couple of reasons.

First, I grew up in a rural community where people simply said, "Boys will be boys." They just needed to burn off energy. I never even heard of ADHD growing up. By the time I learned about it in college, I had already developed workarounds. I relied on discipline and assumed working 16-hour days was just normal.

Second, I was diagnosed with high-functioning autism in my late 30s. Since I already knew I was neurodivergent, I assumed many of my struggles were related to autism rather than ADHD.

It wasn't until my mid-40s that everything started to fall apart. I developed severe anxiety, the discipline that had carried me through my 20s and 30s stopped working, and I couldn't focus or sit still at work. I became impatient and struggled with impulsive anger. My wife and I separated for a time—thankfully we're back together now—but that difficult period made me realize I needed help because the strategies I'd relied on for years were no longer working.”

What has helped you manage your symptoms as an adult with ADHD? What tools or strategies do you use?

“Medication has helped tremendously. It reduced my anxiety and allowed me to focus on what matters most.

Working with a counselor has also been incredibly valuable. It gives me someone to talk through challenges with while continuing to build practical coping strategies.

One of the biggest turning points was attending the Lindner Center's Partial Hospitalization Program (PHP), where I learned mindfulness techniques and skills for regulating intense emotions and staying present.

Walking has also become an important part of managing my ADHD. I'm not someone who enjoys intense exercise, but getting outside and away from technology helps clear my mind.

More than anything, learning how to manage anxiety has made the biggest difference. Scheduling time to worry, practicing mindfulness, and learning not to ruminate have helped me regain a sense of control.”

What do you think your life would have been like if you had been diagnosed earlier?

“I honestly think I might not have separated from my wife.

I probably would have sought help from mental health professionals sooner instead of believing discipline alone could solve everything. There was a point in my early 40s when I accepted that this was simply how life was going to be. I thought I just needed to push harder.

Discipline helped me accomplish a lot, but it also kept me from asking for help because I convinced myself, "That's just the way it is."

Since being diagnosed with ADHD, what has helped the most with improving your executive functioning?

“I'm still working on it.

One strategy that has helped is keeping a "brain dump" list. When thoughts become overwhelming, I write them down instead of trying to carry them all in my head.

For example, my children are getting ready for college, and I can easily become consumed by worries about finances and their future. Sometimes I simply write "college" on a piece of paper so I can bring it up with my counselor or come back to it later with a plan.

It's almost like giving the thought a name. I acknowledge that it's there, but I remind myself that now isn't the time to focus on it.”

What would you like to say to other people who might be struggling with symptoms of inattention or executive dysfunction?

“There is help available.

Watching my wife navigate multiple sclerosis taught me that there are countless medical professionals, treatments, and strategies available to support people facing difficult challenges. That experience encouraged me to seek help for myself.

Most importantly, don't be too hard on yourself.

For years, I believed discipline was always the answer. When it stopped working, I constantly asked myself, "What's wrong with you?" Looking back, that only made my anxiety worse.

Early in my career, I could discipline myself to study 300 hours over four months for professional exams. When I reached my 40s, I couldn't do that anymore, and I blamed myself instead of recognizing that something had changed.

If there's one thing I've learned, it's that asking for help isn't a sign of weakness. Sometimes it's the first step toward understanding how your brain works and finding strategies that actually work with it instead of against it.”
