ADHD and Anxiety: A Common Pairing
Many people who live with ADHD and anxiety will recognize a particular kind of stuck. There’s a small task you’ve been putting off for days, like replying to an email or booking an appointment. You finally sit down to do it, and somehow you end up checking your phone, tidying your desk, or starting something else entirely. Meanwhile, the task sits there, and a familiar knot starts forming in your stomach.
Other people might call it procrastination, and you may have called it that yourself. But when we slow these moments down in therapy, two things are usually going on. One is a brain struggling to find the first step. The other is a nervous system braced for what happens if you get it wrong.
ADHD and anxiety show up together often, and each one can hide or amplify the other. Telling them apart can take patience, but the right support depends on knowing what's driving what.
Does ADHD Cause Anxiety?
ADHD can contribute to anxiety, but having ADHD doesn’t automatically mean you’ll experience anxiety. Anxiety is your mind and body's alarm system, the part of you that scans for danger and tries to get ahead of it. ADHD doesn't switch that alarm on, but living with unrecognized ADHD can give it plenty of reasons to go off.
For example, think about what years of missed deadlines and lost keys might teach someone. Add the comments that usually come with them: "Why can't you just focus?" Most adults with ADHD learn to expect that something will slip long before they know why. Worry is a sensible response to that kind of unpredictability.
With that in mind, you might be surprised to learn that worry and anxiety sometimes take on a very important job in someone’s life. We see it become the fuel that gets someone moving, because a looming deadline creates the urgency an ADHD brain struggles to produce on its own. It can work for years, but the price is a nervous system that hardly ever gets to rest.

Why ADHD and Anxiety Often Co-Occur
If you're dealing with both, know that you’re not alone. A 2025 research review on adult ADHD estimated that anxiety disorders affect between 25% and 50% of adults with ADHD. There's no single reason for the link, but researchers point to a few factors that seem to overlap:
Shared genetic factors. Some inherited traits seem to raise the odds of having both conditions.
Brain chemistry. Both may involve differences in how the brain uses dopamine, a chemical messenger tied to attention and motivation.
Attention and memory difficulties. When it's hard to concentrate or hold information in mind, anxiety has more to feed on. Anxiety, in turn, makes concentrating harder.
Difficulty managing emotions. ADHD can make frustration and other strong feelings more challenging to regulate.
That last factor is typically where we spend a lot of time in therapy sessions. Emotional regulation is the ability to notice a feeling and bring it back down to size. When small setbacks keep landing with full force, the mind learns to scan for the next one. That constant, tiring scan is much of what keeps anxiety working relentlessly.
Recognizing ADHD and Anxiety Symptoms
Below, we’ll cover how ADHD might present day to day, how anxiety does, and where the two overlap, including how anxiety can mask ADHD. Keep in mind that these are everyday examples, not a diagnostic checklist, and seeing yourself in both is common.
ADHD Symptoms
ADHD affects attention, activity, and impulse control. In adults, it usually shows up as a steady, grinding friction with everyday demands.
Difficulty sustaining attention: Losing the thread of a conversation or leaving tasks half finished
Difficulty controlling impulses: Interrupting others or making quick decisions you later regret
Executive functioning difficulties: Struggling to organize, prioritize, start tasks, or manage time, all skills tied to executive functioning in ADHD
Forgetfulness: Misplacing keys, missing appointments, or losing track of instructions moments after hearing them
Restlessness: Fidgeting through meetings or feeling a constant pull to move
Symptom lists regrettably tend to leave out the emotional layer. Many adults with ADHD grew up
hearing they were careless, lazy, or “not living up to their potential.” Carry that long enough and every forgotten task starts to feel like proof of a personal flaw, rather than a sign that your brain needs a different kind of support.
Shame also changes how people cope. Some start double-checking everything, over-preparing for meetings, or staying late so no one suspects they've dropped work. Others steer clear of the tasks that feel most exposing, then feel worse as the deadline closes in. Both patterns make sense as protection, and both can keep you on high alert, which is often how shame turns into anxiety.
In therapy, easing that shame can matter as much as building new strategies. When a missed appointment can be just a missed appointment, there’s more room to figure out what would help next time.

Anxiety Symptoms
Anxiety lives in your thoughts, your body, and your behaviour. It looks different across conditions like generalized anxiety, social anxiety, and panic disorder.
Excessive worry: Thoughts that feel hard to manage or switch off
Fear of judgment or embarrassment: Especially in social settings, a pattern often linked to social anxiety
Avoidance: Steering clear of tasks, conversations, or places because of fear
Physical symptoms: Muscle tension, a racing heart, or an unsettled stomach
Dread or apprehension: A persistent sense that something bad is about to happen
Anxiety is trying to protect you too. It predicts what might go wrong so you can prepare, and in small doses, that’s useful. Trouble starts when it fires too often, and an ordinary work meeting begins to feel like a test you can’t afford to fail.
Avoidance typically keeps the anxiety cycle going. Putting off the email, skipping the meeting, or rehearsing a conversation for the tenth time brings quick relief. That relief teaches your mind that the danger was real and that avoiding it worked, so the worry keeps coming back.
Therapy can help loosen that loop. Instead of fighting the anxiety, therapy can help you notice what it’s warning you about and decide whether the warning fits.
Where Symptoms Overlap
The overlap between ADHD and anxiety can make it hard to tell where one ends and the other begins. Both can bring trouble concentrating, restlessness, irritability, and poor sleep. ADHD is defined partly by executive dysfunction, which means difficulty with the mental skills you use to plan, start, and finish things. Anxiety can knock out those same skills, since a worried mind has less space left for planning.
Anxiety can also mask ADHD. We see this most in high-achieving adults who've used worry and over-preparation to keep everything afloat. Their anxiety gets noticed, and sometimes treated, while the attention difficulties underneath go unrecognized.
So a symptom on its own may not tell you much. Its history matters: whether it’s been part of your life since childhood, or showed up during a stressful stretch. So does its context, like whether it eases on calm days or follows you everywhere. Those details are what start to separate ADHD from anxiety.
How to Tell the Difference Between ADHD and Anxiety
Two people can stare at the same unfinished task for different reasons. One struggles to organize the steps or stay focused, while another fears getting it wrong. Plenty of people have both experiences.
In therapy, we often start with a few simple questions. They won’t give you a diagnosis, but they can help you notice which patterns feel most like yours.
What's pulling your attention away? With anxiety, attention drifts toward worries or possible threats. With ADHD, focus can wander even on a calm, easy day.
When did the difficulties start? ADHD is a long-standing pattern that begins in childhood, even if no one spotted it until adulthood. Anxiety-related difficulties tend to rise and fall with stress.
What happens when the worry eases? If you still lose track of appointments or leave tasks unfinished on calm days, that's worth raising in an ADHD assessment. It's a clue to explore, not proof.
Could both be contributing? Often, yes. ADHD-related difficulties can create worry, and anxiety can make those difficulties harder to manage.
There's one more question we find especially telling: what is the avoidance protecting you from? With anxiety, putting something off usually shields you from a feared outcome, like criticism or failure. With ADHD, the task can feel impossible to grab hold of.

How to Manage ADHD and Anxiety
Most people do best with layered support, pairing a few small changes in daily routines with professional care. What helps most depends on which condition is driving a particular struggle.
Daily Habits and Practical Supports
When ADHD and anxiety overlap, everyday tasks might feel like they take a lot of effort. These small adjustments can make them feel more manageable:
Make the next step smaller. "Finish the report" is a cliff. "Open the document and write three points" is a step, and steps are easier for an ADHD brain and an anxious one alike.
Put reminders outside your head. Use one calendar, visible checklists, and phone alerts so less lives in your memory. But if checking these tools starts to feel like a hunt for reassurance or adds stress, scaling them back might be the best option for you.
Build flexible routines. Tie a task or two to something you already do, like checking your calendar after breakfast. Anchoring to an activity instead of a set time means the routine still works on a day when breakfast happens at 10:00 a.m.
Practice brief grounding. Worry can pull your mind into the future, toward things that haven’t happened yet. Naming five things you can see, or noticing your feet on the floor, brings your attention back to the present. If sitting is hard, try a short walk.
Support sleep and movement. A wind-down routine can help ease sleep issues, and movement you enjoy can make attention and mood easier to manage. Neither is a cure, but both help signal safety to your system.
Start with one change, and shape it around how your mind works. If something doesn't stick, treat that as information about the fit. It isn't a verdict on your effort or your character.
Psychotherapy
Therapy can help you manage anxiety and build skills for organizing, getting started, and riding out strong emotions. An ADHD-informed therapist can also help you build routines and systems that work with your attention, motivation, and energy, so you rely less on worry or last-minute pressure. Most therapists draw on more than one approach:
Cognitive Behavioural Therapy (CBT): Helps you recognize thoughts and habits that keep anxiety going. For ADHD, much of the work is practical: breaking down tasks, trying organizational tools, and figuring out what helps you follow through.
Acceptance and Commitment Therapy (ACT): Helps you take steps toward what matters to you, even when worry, frustration, or boredom makes it challenging to get started or keep going.
Internal Family Systems (IFS): Explores different "parts" of yourself, such as the inner critic or the part that procrastinates, with curiosity instead of judgment. Understanding these parts can help you approach ADHD difficulties with more compassion.
Mindfulness-based practices: Helps you notice when your attention has wandered or you’re about to act on an impulse, giving you a moment to pause and choose what to do next. You can also practice noticing anxious thoughts without getting caught up in them.
Compassion-focused therapy: Helps you work through shame and self-criticism around ADHD difficulties, such as forgetting things, running late, or struggling to get started. You can learn to respond to those moments with understanding and consider what support would help, rather than putting more pressure on yourself.
Therapy is where you can get curious about why one missed deadline sets off a wave of shame, or why rest feels unsafe after years of running on worry. Seeing what’s driving a pattern can make it easier to work on, and a therapist who understands both ADHD and anxiety can help you find ways to stay on top of things without needing to feel anxious to do so.
Medication
Medication can help with ADHD, anxiety, or both, and the right fit looks different for everyone. ADHD medications include stimulant and non-stimulant options, and a prescriber can take your anxiety into account when weighing them. If you do try medication, keep notes on your sleep, appetite, focus, and worry levels, so you have specifics to share at follow-up appointments.
Psychotherapists don't prescribe, so your family doctor or a psychiatrist is the right person to ask whether medication makes sense for you.
How Therapy Can Help
When ADHD and anxiety show up together, support has to be personalized to target both at once.
Without that dual approach, a strategy that helps one may inadvertently work against the other.
Take checking your to-do list throughout the day. For someone with ADHD, it's a sensible way to stay organized. For someone who also experiences anxiety or Obsessive-Compulsive Disorder (OCD), the same habit can turn into a way of seeking reassurance or briefly quieting distress.
Nothing is wrong with the list itself, and what we'd want to understand is why you're checking and how you feel once you have.
In therapy, we work through patterns like these together and adapt practical tools so they support both conditions. Our psychotherapists use evidence-based approaches, including CBT and mindfulness-based practices. Our team also includes therapists with lived experience of ADHD and neurodiversity, so these struggles aren't abstract to us.
We offer both anxiety therapy and ADHD therapy, and many people who come to us are working through both at once. Sessions are offered in person at our Toronto clinic or online. If you’re not sure where to begin, a free therapist-matching call with our Care Coordinator can help.
Frequently Asked Questions
Does ADHD cause anxiety?
Not directly, but the two are closely connected. The daily stress of ADHD, like missed deadlines or frequent criticism, can build into persistent worry over time.
Can ADHD be masked by anxiety?
Yes, anxiety can mask ADHD. Someone who works extra hard to avoid mistakes may look like they’re just worried, while the underlying struggle with focus and organization goes unnoticed.
Can you have ADHD and anxiety at the same time?
Yes, and it's common. Research suggests up to half of adults with ADHD also live with an anxiety disorder.
How do I know if I have ADHD or anxiety?
Only a qualified professional can assess this. Before an appointment, it can help to notice when your difficulties began, whether they show up on calm days, and what your avoidance seems to protect you from.
