People with ADHD often interrupt. They know they do it. They hate that they do it. And yet the words come out anyway, cutting across someone mid-sentence before they’ve even registered what’s happened.
This is one of the most visible symptoms of ADHD in adults. It’s also one of the most misunderstood.
It gets mistaken for rudeness. Impatience. A lack of interest in what others have to say. Partners get hurt. Colleagues get frustrated. And the person with ADHD is left wondering why they can’t just stop, despite genuinely wanting to.
If someone close to you has this pattern, or if you’re noticing it in yourself and wondering whether something deeper is going on, an ADHD assessment can help clarify whether these behaviours are part of a broader neurological picture.
Because interrupting in ADHD isn’t a listening problem or a manners problem.
It’s an emotional regulation problem.
And that distinction matters.
It’s Not Just Impulsivity
The surface explanation is impulsivity. ADHD involves difficulty inhibiting responses, and interrupting is one of the ways that plays out in conversation.
But impulsivity on its own doesn’t capture what’s actually happening.
What I see clinically, and what the research increasingly supports, is that emotional dysregulation sits at the centre of this. People with ADHD don’t just struggle to regulate negative emotions. They struggle to regulate positive ones too.
When a conversation is stimulating, it triggers thoughts. Connections. Stories they’re suddenly desperate to share. The excitement builds. And regulating that excitement, holding it back, waiting for their turn, is genuinely difficult.
It’s not that they don’t care what the other person is saying.
It’s that their nervous system is firing faster than their intentions can keep up with.
The Two Reasons Behind the Interrupting
There are two patterns I notice again and again.
Excitement-driven interrupting
The conversation is engaging. Something triggers an idea, a memory, a connection. The person with ADHD isn’t bored at all. They’re the opposite. They’re so engaged that the urge to contribute becomes almost physical. The thought arrives with momentum, and holding it back feels impossible.
Someone with ADHD will constantly be reminded of a story based on something you said. And they are dying to tell you that story. The impulsivity has created excitement in them, and that’s why they interrupt.
Boredom-driven interrupting
The conversation is too slow. The other person is going into detail they can’t hold onto. Their attention is drifting, and the understimulation becomes uncomfortable. Interrupting becomes a way to redirect things. To inject some energy. To create the stimulation their brain is craving.
The conversation is going at far too slow a pace for them, and they cannot tolerate the boredom of that.
Both of these come down to regulation.
In one case, they’re trying to regulate excitement. On the other hand, they’re trying to regulate boredom. Either way, these are tiny fluctuations happening constantly throughout a conversation.
Even the most self-aware adults with ADHD find this hard. They might know they have this tendency. They might be watching themselves do it. And the urge to speak still wins, because the drive to regulate those internal states is stronger than the intention to stay quiet.
Why Knowing Doesn’t Help Them Stop
This is the part that confuses people most.
The person with ADHD is aware of the pattern. They’ve been told about it. They’ve made genuine resolutions to listen more and speak less.
And it keeps happening anyway.
Part of this is working memory. A thought arrives, and there’s a real fear that if they don’t voice it now, it will vanish. This isn’t irrational. Working memory limitations mean that holding a thought while simultaneously tracking what someone else is saying, monitoring social cues, and waiting for an appropriate pause is genuinely harder than it sounds.
But the deeper issue is that the strategies people suggest, counting to three, waiting until the other person finishes, taking a breath, all rely on executive functions that are already compromised in ADHD.
Inhibition. Self-monitoring. Emotional regulation.
These are the tools someone would need to implement the advice. And they’re precisely what’s impaired.
This is why tips and tricks often don’t work. Not because the person isn’t trying. But because the intervention is asking them to use capacities that are already stretched thin.
The Relationship Cost
Chronic interrupting takes a toll on relationships.
Partners feel unheard. Friends stop sharing as much. Colleagues make assumptions about the person’s interest or respect. Over time, these small ruptures accumulate into something larger.
And there’s an internal cost too.
Most adults with ADHD who interrupt frequently are acutely aware of it. They notice the flicker of irritation on the other person’s face. They replay conversations afterwards, cringing at the moments they talked over someone.
The shame builds.
And shame doesn’t help. It often makes the pattern worse, because shame itself is an emotional activation that’s hard to regulate. They feel bad, which makes them more dysregulated, which makes them more likely to interrupt again.
There’s a painful mismatch here. Internally, interrupting doesn’t feel like dominance or control. It feels like urgency. Like overflow. But externally, it lands differently. Partners and colleagues experience it as dismissal, even when the internal experience is the opposite.
That gap, between how it feels and how it lands, is one of the hardest parts of being in a relationship with someone who has ADHD.
What the Research Says
A growing body of evidence supports what many adults with ADHD already sense: that emotional dysregulation is central to the condition, not a side issue.
A 2023 review by Petrovic and colleagues argues that emotion dysregulation should be considered a core feature of adult ADHD. Adults with ADHD tend to experience emotions more intensely, react more quickly, and take longer to return to baseline after emotional activation.
Russell Barkley’s influential model frames ADHD as a disorder of self-regulation, where deficits in inhibition and working memory make it difficult to modulate emotional responses in real time. In conversation, this translates to difficulty holding back comments, especially when emotionally activated.
A 2024 feasibility study by Sjöwall and colleagues found that emotion dysregulation contributes substantially to impairment in adults with ADHD, often independently of core symptoms like inattention. And traditional ADHD treatments, which tend to focus on organisation and planning, frequently underaddress this emotional dimension.
This is why willpower-based approaches tend to fail. They assume the executive functions needed to implement them are intact. In ADHD, they often aren’t.
What Actually Helps
If willpower doesn’t work, what does?
Understanding the mechanism
When partners and family members understand that interrupting is tied to emotional regulation rather than character, it changes the dynamic. It doesn’t excuse the behaviour, but it reframes it. Instead of interpreting it as disrespect, they can see it as something the person is struggling to manage.
Open communication
When someone with ADHD can explain to their partner or close friends that they’re aware of this pattern and working on it, it reduces the hurt. The other person isn’t left wondering whether they’re being dismissed. They understand what’s happening.
Building emotional regulation skills
The more substantial work involves developing the ability to notice emotional surges as they arise and create space before acting on them. This is what therapies like DBT focus on. A 2022 randomised controlled trial of DBT-based group therapy for adults with ADHD found improvements in executive functioning, ADHD symptoms, and quality of life. The gains in emotion regulation were clearer over time, suggesting that these skills take practice.
Practical accommodations
Some things help in the moment:
- Writing down thoughts during a meeting so they don’t have to hold them in working memory
- Agreeing on a gentle, non-shaming signal when they’ve interrupted
- Choosing social contexts where rapid back-and-forth is appropriate, rather than forcing a conversational style that doesn’t fit
- Giving themselves permission to say “I have a thought, can I jump in?” rather than trying to suppress the urge entirely
These aren’t fixed. They’re accommodations. The deeper work tends to involve therapy that addresses the emotional dysregulation underlying many ADHD difficulties.
