How Do You Tell the Difference Between ADHD Racing Thoughts and Anxiety? | ADHD Webinar Q&A

‍

During our recent webinar, ADHD Without the Shame: From Diagnosis to Empowerment, attendees submitted dozens of thoughtful questions about ADHD assessment, treatment, and life beyond diagnosis. While we addressed many of them live, we wanted to make sure every question received a more complete response. This blog series is our way of continuing that conversation.

When it comes to ADHD and anxiety, there are some symptom overlap and often, clients will ask: How do you tell the difference between racing thoughts in ADHD and racing thoughts in anxiety? This is a really good question, because on the surface, they can feel very similar. But the reason behind them is often different, and that matters when it comes to what actually helps.

What are “Racing Thoughts”?

Racing thoughts often feel like your mind is moving faster than you can keep up. Thoughts may jump quickly from one idea to another, or feel overwhelming and hard to organize. It can be difficult to focus or stay with one thought long enough to follow it through. This can show up in both ADHD and anxiety, which is why it can be confusing.

The key difference is not just how fast the thoughts are, but what is driving them.

Racing Thoughts in ADHD

In ADHD, racing thoughts are often connected to how the brain processes stimulation, attention, and ideas. Instead of one clear train of thought, it can feel like multiple tabs are open at once, with ideas branching off quickly. Thoughts may shift based on interest, curiosity, or whatever is most stimulating in the moment.

These thoughts are not always negative. They can feel creative, random, or loosely connected. Many people describe this as their brain not slowing down, or not being able to stick to one thought long enough to follow through. This is related to differences in executive functioning and attention regulation (Barkley, 2012).

A helpful way to think about this is asking yourself whether your thoughts feel like they are jumping in multiple directions because your attention is being pulled around.

Racing Thoughts in Anxiety

With anxiety, racing thoughts tend to be more focused and repetitive, even if they feel fast. Instead of jumping topics, they often circle around the same concern or scenario. Thoughts may replay what could go wrong, focus on uncertainty, or try to problem-solve potential threats.

These thoughts are usually future-focused and worry-based. Many people describe this as their brain getting stuck on something and not being able to let it go. This pattern is often linked to the brain’s threat detection system trying to anticipate and prevent harm (American Psychiatric Association, 2022).

A helpful way to think about this is asking whether your thoughts feel like they are looping around something that feels stressful or unsafe.

The Key Difference

If we zoom out, the difference often looks like this. In ADHD, thoughts tend to be fast, shifting, and scattered. In anxiety, thoughts tend to be fast, but repetitive and focused on worry.

Another way to think about it is that ADHD feels like too many directions, while anxiety feels like being stuck in one direction.

What if it Feels Like Both?

Many people experience both ADHD and anxiety, and the two can interact in ways that make things feel more overwhelming. ADHD can make it harder to organize or complete tasks, which can lead to stress and pressure. That stress can then trigger anxiety. At the same time, anxiety can increase mental load, which makes executive functioning feel more difficult.

If it feels like both, that can often mean it is both. The goal is not to perfectly label the experience, but to understand what is happening well enough to respond in a way that helps.

What Helps Calm Racing Thoughts?

The reason this distinction matters is because what helps is different depending on what is driving the experience.

If the pattern is more related to ADHD, it can help to externalize thoughts, reduce input, and break tasks into smaller, more concrete steps. If the pattern is more related to anxiety, it can help to ground attention in the present, gently interrupt worry loops, and work with the underlying fear or uncertainty.

Approaches like Cognitive Behavioural Therapy can support both, but the focus will look different depending on what is driving the thoughts (Hofmann et al., 2012).

A More Compassionate way to Understand Racing Thoughts

Racing thoughts in ADHD and anxiety can feel very similar, but they tend to come from different places. ADHD is often about how attention is regulated, while anxiety is often about how the brain responds to perceived threat. Sometimes, it is both.

It is quite common for people to interpret racing thoughts as a personal failure or something being wrong with them. But racing thoughts are not a character issue. They are a signal.

They reflect how your brain is trying to process, problem-solve, or protect you. Understanding the pattern behind them can make it easier to respond with more clarity and less self-blame. The goal is not to get the label perfect. It is to understand what your brain is doing, so you can support it in a way that actually works.
