I was surprised by some of these findings when I first dug into the research.
I’ve spent a lot of time studying this topic. Here’s what I found.
For a long time I thought I had an anxiety disorder. I was always worried about something. My mind never stopped racing. Then I got an ADHD diagnosis. I understood something important. Much of my anxiety came from ADHD. I had both conditions at the same time.
ADHD and Anxiety Together
About 50% of adults with ADHD also have an anxiety disorder [1]. This high rate is not by chance. There are brain, mind, and life reasons why these two conditions go together. A big study called the National Comorbidity Survey Replication found something important. Among adults with ADHD, 47% had at least one anxiety disorder [1]. These include generalized anxiety disorder (GAD), social anxiety disorder, panic disorder, and specific phobias. The NIMH says that ADHD and anxiety together are common enough. Doctors should now check for both at the same time.

To understand why these two conditions overlap so much, we need to look at two things. First, there are shared brain reasons. Second, there is what it’s like to grow up with ADHD.
How ADHD Creates Anxiety
A Long History of Failure
Most people with ADHD fail repeatedly from childhood on. They can’t focus. They forget things. They turn in work late. These bad experiences build up. They create a fear of failure: “I will mess up again” [2]. This is called performance anxiety from ADHD. The brain has learned to expect failure before a task even starts. This anxiety is not the main problem. It is a scar from years of not meeting expectations.
Working Too Hard to Hide ADHD
Hiding ADHD symptoms and looking “normal” takes huge effort. This effort creates stress and makes anxiety worse. People with ADHD use a lot of brain power. They watch their own behavior. They check their work twice. They practice social talks. Non-ADHD people use this brain power for actual tasks. This constant watching keeps tension high. The tension feels like anxiety.
Time Blindness and Deadline Stress
People with ADHD often wait until the last moment. This happens because they can’t sense time well. Their brain stays on alert: “something bad is about to happen again” [3]. Barkley’s research shows ADHD is a time disorder. When you can’t sense the future coming, you stay in a state of low-level worry. This feels like general anxiety.
Shared Symptoms: The Diagnosis Problem
ADHD and anxiety share many surface symptoms. This makes diagnosis hard:
