ADHD and Co-Occurring Conditions: Anxiety, Mood, and Learning Disorders

Welcome or welcome back to Authentically ADHD, the podcast where we embrace the chaos and magic of the ADHD brain. Im carmen and today we're diving into a topic that's as complex as my filing system (which is to say, very): ADHD and its common co-occurring mood and learning disorders. Fasten your seatbelts (and if you're like me, try not to get distracted by the shiny window view) – we're talking anxiety, depression, OCD, dyslexia, dyscalculia, and bipolar disorder, all hanging out with ADHD.

Why cover this? Because ADHD rarely rides solo. In fact, research compiled by Dr. Russell Barkley finds that over 80% of children and adults with ADHD have at least one other psychiatric disorder, and more than half have two or more coexisting conditions. Two-thirds of folks with ADHD have at least one coexisting condition, and often the classic ADHD symptoms (you know, fidgeting, daydreaming, “Did I leave the stove on?” moments) can overshadow those other disorders. It’s like ADHD is the friend who talks so loud at the party that you don't notice the quieter buddies (like anxiety or dyslexia) tagging along in the background.

But we’re going to notice them today. With a blend of humor, sass, and solid neuroscience (yes, we can be funny and scientific – ask me how I know!), we’ll explore how each of these conditions shows up alongside ADHD. We’ll talk about how they can be misdiagnosed or missed entirely, and—most importantly—we’ll dish out strategies to tell them apart and tackle both. Knowledge is power and self-awareness is the key, especially when it comes to untangling ADHD’s web of quirks and comrades in chaos. So, let’s get into it!

ADHD and Anxiety: Double Trouble in Overdrive

Let’s start with anxiety, ADHD’s frequent (and frantic) companion. Ever had your brain ping-pong between “I can’t focus on this work” and “I’m so worried I’ll mess it up”? That’s ADHD and anxiety playing tango in your head. It’s a double whammy: ADHD makes it hard to concentrate, and anxiety cranks up the worry about consequences. As one study notes, about 2 in 5 children with ADHD have significant problems with anxiety, and over half of adults with ADHD do as well. In other words, if you have ADHD and feel like a nervous wreck half the time, you’re not alone – you’re in very good (and jittery) company.

ADHD and anxiety can look a lot alike on the surface. Both can make you restless, unfocused, and irritable. I mean, is it ADHD distractibility or am I just too busy worrying about everything to pay attention? (Hint: it can be both.) Especially for women, ADHD is often overlooked and mislabeled as anxiety. Picture a girl who can’t concentrate in class: if she’s constantly daydreaming and fidgety, one teacher calls it ADHD. Another sees a quiet, overwhelmed student and calls it anxiety. Same behavior, different labels. Women in particular have had their ADHD misdiagnosed as anxiety or mood issues for years, partly because anxious females tend to internalize symptoms (less hyperactive, more “worrier”), and that masks the ADHD beneath.

So how do we tell ADHD and anxiety apart? One clue is where the distraction comes from. ADHD is like having 100 TV channels in your brain and someone else is holding the remote – your attention just flips on its own. Anxiety, on the other hand, is like one channel stuck on a horror movie; you can’t focus on other things because a worry (or ten) is running on repeat. An adult with ADHD might forget a work deadline because, well, ADHD. An adult with anxiety might miss the deadline because they were paralyzed worrying about being perfect. Both end up missing the deadline (relatable – ask me how I know), but for different reasons.

Neuroscience is starting to unravel this knot. There’s evidence of a genetic link between ADHD and anxiety – the two often run in the family together. In brain studies, both conditions involve irregularities in the prefrontal cortex (the brain’s command center for focus and planning) and the limbic system (emotion center). Essentially, if your brain were a car, ADHD means the brakes (inhibition) are a bit loose, and anxiety means the alarm system is hyper-sensitive. Combine loose brakes with a blaring alarm and you get… well, us. Fun times, right?

Here’s an interesting tidbit: Females with ADHD are more likely to report anxiety than males. Some experts think this is partly due to underdiagnosed ADHD – many girls grew up being told they were just “worrywarts” when in fact ADHD was lurking underneath, making everyday life more o
