ADHD or OCD, or Both? How to Tell the Difference in Adults
You've checked the stove three times.
Or you haven't, because you honestly can't remember whether you already did.
Maybe you've walked into a room and forgotten why. Maybe you've lost your keys again, missed another deadline, and started a task you never finished.
And now you're wondering whether something is wrong with your attention.
Or maybe it's the opposite. You can't stop going back over what you said, whether you locked the door, whether you sent the email correctly.
You know it doesn't make sense, and you do it anyway, because the doubt won't quiet down until you do.
Or maybe both are true. You're scattered and stuck in loops, and you've never been able to tell whether the problem is an attention issue, an anxiety issue, or something you haven't found a name for yet.
If any of this sounds familiar, you may be asking a question many adults bring to therapy: is this ADHD, OCD, or both?
That's exactly what we help adults untangle through online therapy in Massachusetts, from wherever you are in the state.
The confusion makes sense. ADHD and OCD can look surprisingly alike on the surface. Both can involve forgetfulness, checking, procrastination, distraction, and feeling mentally overloaded.
But the reasons underneath are very different, and treating one when you have the other can leave you exactly where you started.
Watch this short video for an example:
What Is the Difference Between ADHD and OCD?
At the core, the two conditions work in opposite ways.
ADHD is a neurodevelopmental condition that affects attention, organization, impulse control, and the brain's ability to regulate effort and follow through. It usually begins in childhood, even if it went unnoticed for years.
OCD is a cycle of obsessions and compulsions. Obsessions are unwanted, distressing thoughts, doubts, or urges. Compulsions are the behaviors or mental acts you do to get relief from them.
The relief is temporary, and the cycle strengthens.
Here's a simple way to think about it: ADHD is largely a problem of too little internal regulation, so attention drifts and things get missed.
OCD is largely a problem of too much doubt, so the brain stays stuck on something it can't let go of.
The Symptoms That Look the Same — But Aren't
Many of the most frustrating symptoms overlap. Here's how they can differ.
Checking
With ADHD, you may check things because you genuinely didn't register them the first time. You didn't notice turning off the stove, so you go back and look.
With OCD, you often did notice, and you check anyway. The doubt isn't about whether you paid attention. It's about whether you can be sure.
Checking gives a moment of relief, then the doubt returns and you check again.
Trouble Concentrating
With ADHD, attention drifts to whatever is more interesting, novel, or urgent, and boring but important tasks slip away.
With OCD, attention gets pulled inward by intrusive thoughts, mental reviewing, and urges. You're not distracted by the world. You're distracted by what's happening in your head.
Procrastination
With ADHD, starting is the hard part. You know what to do and can't get your brain to begin, especially when the task is tedious or unclear.
With OCD, the struggle is often about doing it right. Rituals, perfectionism, or "just right" feelings can slow everything down, and avoidance protects you from the fear of getting it wrong.
Disorganization vs. Order
With ADHD, clutter, lost items, and disorganized systems are common, and they cause stress rather than relief.
With OCD, some people feel driven to arrange things a certain way until it feels "right," and the distress comes from things being out of place.
Impulsivity vs. Intrusive Thoughts
This one gets confused often.
With ADHD, impulsivity means acting or speaking before thinking, like blurting things out or making quick decisions.
With OCD, intrusive thoughts are unwanted and distressing, and the person is frightened of them, so they work hard not to act. An intrusive thought is not an impulse. In OCD, the fear of a thought is usually the whole problem.
Our post on Pure O OCD explains how this can look from the outside.
Why Getting It Wrong Keeps You Stuck
When the cause is misread, the solutions miss.
If you have ADHD but treat it as OCD, you may end up chasing certainty when what you actually need is structure, systems, and skills for attention and follow-through.
If you have OCD but treat it as ADHD, planners, reminders, and checklists can quietly become compulsions. Every "let me just double-check" feels like productivity, but it's feeding the cycle.
Either mismatch leaves people feeling like they're failing at something everyone else finds easy, when the real issue is that the approach doesn't match the problem.
What Most People Miss: Often, It's Both
ADHD and OCD can occur together, and they can complicate each other.
Years of forgetting, missing things, and being told to "just pay attention" can make someone check compulsively. Sometimes that's not OCD at first, but a coping strategy that eventually hardens into something bigger.
And OCD can look like inattention when a mind is busy with mental rituals and intrusive thoughts.
Adults who are diagnosed later in life often describe both stories at once. Our post on late-diagnosis ADHD explores this.
Timing can be a clue. ADHD tends to show up throughout life, with signs going back to childhood. OCD often has a more distinct pattern of obsessions and rituals that can start at any age and intensify under stress.
And sometimes what looks like either one is really general worry, which our guide to OCD vs. anxiety helps sort out.
When both are present, the order and pacing of treatment matters. ERP, the gold-standard treatment for OCD, asks a lot of your attention and consistency. ADHD skills and support can make it easier to do the work.
Treating both thoughtfully often leads to better results than treating either alone. You can read more in our post on ERP therapy.
How Therapy Treats ADHD and OCD
The right approach starts with understanding what's actually driving your symptoms, then building a plan that fits.
Therapy for ADHD and OCD might look like:
Sorting out which behaviors come from attention and organization and which come from obsessions and compulsions
Using ERP therapy to break the cycle of doubt, checking, reassurance-seeking, and mental review
Building practical systems for time, priorities, and follow-through that support your brain without turning into rituals
Learning to spot when a helpful ADHD strategy has quietly become a compulsion
Adding structure and accountability so the work of therapy is easier to sustain
Untangling years of self-criticism from living with symptoms that were never understood
None of this is about trying harder.
It's about using the right tools for the right problem, and getting support while you build them.

Online therapy is a strong fit for both conditions, not a compromise.
Here are some of the benefits of online therapy for ADHD and OCD:
Less friction to show up. Commutes and travel time are exactly the kind of planning tasks that make ADHD harder. Removing them means fewer missed sessions.
Skills built where the struggle happens. ERP and ADHD strategies can be practiced in your own home, workspace, and routines, where OCD and daily life actually play out.
Easier to fit into a full day. Sessions can slot into a break or a gap in your schedule.
Comfort while doing hard work. Many people find it easier to open up about difficult thoughts from a familiar space.
Access statewide. Wherever you are in Massachusetts, you can work with therapists who specialize in these conditions.
