ADHD and Anxiety
Why They So Often Go Together (and What Actually Helps)
If you have ADHD, there's a good chance you also live with anxiety. Not just the ordinary worry that most people experience from time to time — but a persistent, exhausting undercurrent of tension, hypervigilance and dread that follows you through your days. This isn't a coincidence. The relationship between ADHD and anxiety is well-documented, deeply intertwined, and frequently misunderstood. Understanding why they so often appear together is the first step towards getting support that actually works.
How common is it?
Research suggests that around 50% of adults with ADHD also have an anxiety disorder — making it one of the most common co-occurring conditions. Many more experience significant anxiety symptoms that don't meet the threshold for a formal diagnosis but still have a profound impact on daily life. The relationship runs in both directions. ADHD can cause anxiety. But anxiety can also look like ADHD — creating a diagnostic picture that is genuinely complex, and that requires careful, individualised support.
Why does ADHD cause anxiety?
The short answer is: living with an unaccommodated ADHD brain in a world built for neurotypical people is inherently anxiety-generating.
Consider what a typical day might involve for an adult with unmanaged ADHD:
Forgetting an important meeting or deadline
Arriving late despite leaving in good time
Losing your keys, phone, or wallet — again
Saying something impulsive that you immediately regret
Starting the day with good intentions and ending it having achieved almost none of them
Feeling overwhelmed by a to-do list that seems to grow faster than you can address it
Over time, this pattern creates a nervous system that is perpetually braced for the next mistake. The brain learns — quite reasonably — that things go wrong, that you can't fully trust yourself, and that vigilance is necessary for survival. That's anxiety — not a character flaw, but an entirely logical adaptation to a lifetime of difficulty.
The shame spiral
For many adults with ADHD, anxiety is deeply connected to shame. Years of being told you're not trying hard enough, being forgetful, disorganised or unreliable — often by people who had no idea about the underlying neurodevelopmental difference — leave their mark.
The inner critic that develops can be ferocious. And the anticipation of failure — the anxiety about the next thing that will go wrong — becomes as debilitating as the difficulties themselves.
Rejection sensitive dysphoria (RSD) is a particularly intense manifestation of this — an extreme emotional response to perceived criticism or rejection that is especially common in people with ADHD, and that can drive significant anxiety around relationships and social situations.
When anxiety looks like ADHD — and vice versa
This is where it gets complicated. Many of the symptoms of anxiety overlap with those of ADHD:
Difficulty concentrating — present in both
Restlessness and physical tension — present in both
Sleep difficulties — present in both
Avoidance of tasks — present in both
Emotional dysregulation — present in both
This means that anxiety is frequently missed in people with ADHD (attributed to the ADHD), and ADHD is frequently missed in people presenting with anxiety (the ADHD is masked by the anxiety, or the anxiety is assumed to be the primary problem). Getting an accurate picture of what's driving what — and treating both — is essential.
ADHD, anxiety and the nervous system
Both ADHD and anxiety involve dysregulation of the nervous system. In ADHD, the brain's regulatory systems — particularly those involving dopamine and noradrenaline — function differently, making it harder to modulate arousal, attention and emotional response. In anxiety, the threat detection system (the amygdala) is chronically overactivated, keeping the body in a state of low-level fight or flight.
When both are present, the nervous system is working overtime. The result is often a person who oscillates between hyperactivation (overwhelm, anxiety, emotional flooding) and shutdown (avoidance, procrastination, dissociation) — sometimes within the same day.
This is why approaches that work purely at the cognitive level — trying to think your way out of anxiety, or apply rational organisational strategies to an overwhelmed brain — often have limited effect. The nervous system needs to be addressed directly.
What actually helps
Treating both conditions, not just one
It's common for anxiety to be treated without the underlying ADHD being identified — or for ADHD strategies to be applied to a brain that is also significantly anxious. Both approaches have limited effectiveness. The most helpful support addresses both the ADHD and the anxiety, understanding how they interact in your specific situation.
Nervous system regulation
Because both ADHD and anxiety involve nervous system dysregulation, approaches that work directly with the nervous system can be particularly effective. This includes:
Clinical hypnotherapy — working at the level of the unconscious mind to calm the threat response and reduce the hypervigilance that drives anxiety. Hypnotherapy for anxiety can be particularly effective when anxiety has a strong nervous system component, as it so often does in ADHD.
Somatic approaches — body-based techniques that help regulate the nervous system from the bottom up
Exercise — one of the most effective interventions for both ADHD and anxiety, supporting dopamine regulation and nervous system balance
Sleep — poor sleep significantly worsens both ADHD symptoms and anxiety. Hypnotherapy for sleep can help break the cycle of anxious wakefulness that many ADHD adults experience.
ADHD coaching
Working with a specialist ADHD coach to develop strategies that reduce the daily friction that generates anxiety in the first place — better systems for time management, organisation and task initiation — can significantly reduce the background level of stress and overwhelm that feeds anxiety.
Understanding your own pattern
One of the most valuable things you can do is develop a clear picture of how ADHD and anxiety interact for you specifically. For some people, anxiety is primarily driven by the practical difficulties of ADHD — reduce the chaos, reduce the anxiety. For others, the anxiety has taken on a life of its own and needs direct treatment. For many, it's both.
A note on medication
Stimulant medication for ADHD can reduce anxiety in some people — by improving executive function and reducing the daily overwhelm that generates it. In others, stimulants can increase anxiety, particularly at higher doses. This is something to discuss carefully with your prescribing doctor if medication is part of your treatment plan. Non-stimulant medications are also available and may be better tolerated by people with significant anxiety. Again, a conversation for your psychiatrist or GP.
