Quick Answer
Yes, it is possible to have both OCD and ADHD. While they are different conditions, they can occur together and sometimes create symptoms that are difficult to untangle. A thorough ADHD assessment can help clarify whether difficulties with attention, organization, task completion, or focus are related to ADHD, OCD, another condition, or a combination of factors.

If you’ve ever felt like your brain is both easily distracted and incredibly difficult to distract from certain thoughts, you may have wondered how that’s possible.
You might struggle to answer emails, stay organized, or get started on everyday responsibilities, yet find yourself spending hours analyzing one particular thought. You may lose track of time because you were distracted, but you may also lose an hour because you couldn’t stop checking, researching, reviewing, or thinking about something.
This can be particularly confusing when you’re trying to determine whether you have ADHD, OCD, or both.
I often see adults who come in with questions about attention, procrastination, organization, or difficulty getting things done and are surprised to discover that there may be more than one factor contributing to what they’re experiencing. Others have spent years assuming they simply have an “overactive mind” without realizing that ADHD and OCD can affect attention in very different ways.
The important question isn’t always “What symptom am I experiencing?” It’s often “What is driving this symptom?”
Why OCD and ADHD Can Be Difficult to Tell Apart
When adults come to us wondering whether they have ADHD, they’re not always describing symptoms that fit neatly into one category. Difficulty concentrating, procrastination, overthinking, perfectionism, or getting stuck on a task can have several possible explanations.
A pattern we sometimes hear in assessments is, “I keep putting things off because I’m worried I’ll do them wrong.” At first, that can sound like ADHD-related procrastination. But when we explore it further, one person may be struggling to organize the steps and get started, while another may be repeatedly checking, rewriting, or seeking reassurance because they don’t feel certain enough to move on. The behaviour can look similar from the outside, but what is driving it can be quite different.
The key is to look at what is happening beneath the behavior.
As the founder of The Mindful Adult and someone who has ADHD myself, this is something I’ve become very aware of over the years. I can get completely absorbed in researching something that interests me and have difficulty task shifting, while another person may appear just as intensely focused but be driven by anxiety, intrusive thoughts, or a need to feel certain. From the outside, those behaviours can look remarkably similar. What I’ve learned, both personally and through working with adults with ADHD, is that understanding what’s driving the behaviour is often much more important than the behaviour itself.
With ADHD, difficulties often involve regulating attention, managing time, organizing tasks, and following through on intentions. With OCD, attention may become consumed by intrusive thoughts, doubts, fears, or compulsive behaviors intended to reduce distress or create a sense of certainty.
These patterns can also occur together. Someone may struggle with task initiation because of ADHD, finally get started, and then become caught up in an intrusive thought or need to check something repeatedly.
This is why we look at the overall pattern of symptoms rather than relying on one behavior as evidence of a particular diagnosis. Understanding what is driving the difficulty can provide much more useful information than simply identifying what the behavior looks like.
Can You Have OCD and ADHD at the Same Time?
Yes. A person can meet criteria for both ADHD and OCD.
When both conditions are present, however, it can become difficult to determine which condition is contributing to a particular difficulty.
ADHD may make it difficult to organize your day, remember responsibilities, shift between tasks, or follow through with plans. OCD may then pull your attention toward an intrusive thought, fear, or ritual.
The result can look contradictory.
You might spend two hours intensely focused on one concern while being unable to spend 20 minutes completing an important work task.
We sometimes hear questions along the lines of:
“If I can focus on one thing for hours, how can I possibly have ADHD?”
The answer is that ADHD does not mean you are incapable of focusing. The issue is often regulating and directing attention consistently.
OCD can also capture attention, but the underlying process is different. The attention may become stuck because of an intrusive thought, fear, doubt, or perceived need to complete a compulsion.
Understanding what is keeping your attention there is often more clinically useful than simply looking at how long you were able to focus.
How Are OCD and ADHD Different?
OCD and ADHD can look similar on the surface, but the reason behind the behavior can be very different.
With ADHD, your attention may shift because a task is boring, another stimulus is more interesting, you lose your train of thought, or you have difficulty maintaining attention over time. The Centers for Disease Control and Prevention (CDC) explains that adults with ADHD may have difficulty managing attention, staying organized, and completing lengthy tasks.
With OCD, your attention may repeatedly return to a particular fear, doubt, thought, or need to perform a ritual. The National Institute of Mental Health (NIMH) describes OCD as involving recurring, unwanted thoughts and/or repetitive behaviors that can cause significant distress or interfere with daily life.
We sometimes hear adults describe rereading an email five or six times before they can bring themselves to press send. The important question for us isn’t simply, “How many times did you reread it?” It’s why. Were you losing your place and forgetting what you had already checked? Or did you know the email was probably fine but still feel unable to send it until you were completely certain there wasn’t a mistake?
If ADHD is contributing, you may reread the email because you became distracted, lost track of what you were looking for, or forgot what you had already reviewed.
If OCD is contributing, you may reread it because you’re afraid you made a mistake. Even after checking several times, you may still feel unable to press send because you don’t feel completely certain that the email is “right.”
The behavior is similar.
The reason behind the behavior is not.
This is one of the reasons we look beyond individual symptoms when assessing ADHD. A checklist can tell us what is happening, but understanding the pattern and context helps us understand why it is happening.
Can OCD and ADHD Symptoms Look Similar?
Yes, and this overlap is one of the reasons adults can have difficulty figuring out what is actually contributing to their symptoms.
Both conditions can interfere with concentration, productivity, organization, and completing tasks. But the experience leading up to the difficulty can be very different.
For example, imagine you have an assignment due Friday.
With ADHD symptoms, you might intend to start on Monday but repeatedly put it off. When you finally sit down, you may struggle to decide where to begin, check your phone, get distracted by another task, and realize an hour has passed.
With OCD, you might sit down and begin the assignment but become stuck on one paragraph. You may repeatedly rewrite it because you’re worried it isn’t good enough. You might spend hours researching a small detail because you aren’t comfortable moving forward without being completely certain.
Both situations can result in an unfinished assignment.
But the barriers are different.
Perfectionism can make this even more complicated. Perfectionistic behavior can occur for a number of reasons, and it does not automatically indicate OCD. In OCD, however, perfectionistic behavior may be connected to intrusive doubts, distress, or compulsive attempts to reach certainty.
That is why simply asking whether you procrastinate, overthink, or have difficulty concentrating doesn’t always provide the full picture.
What Does Having Both OCD and ADHD Feel Like?
When ADHD and OCD occur together, daily life can feel particularly frustrating because the conditions can interfere with each other in different ways.
You may have a long list of things you need to accomplish but struggle to determine where to start. Once you finally begin, an intrusive thought may pull your attention away. You may then feel compelled to resolve that thought before returning to the original task.
An hour later, you realize very little of the original task has been completed.
Or you may experience the opposite.
You may know that repeatedly checking, researching, or seeking reassurance is keeping you stuck, but ADHD-related difficulties with attention, organization, or follow-through can make it harder to consistently use the strategies you’ve learned.
This can create a particularly discouraging experience:
You know what you want to do. You understand what would probably help. But putting it into practice consistently feels much harder than it should.
That experience can lead to a lot of self-criticism.
We sometimes meet adults who are incredibly frustrated with themselves because they understand exactly what they “should” be doing. They may have learned strategies for managing their OCD, have reminders and lists to help with ADHD, and still struggle to use those tools consistently in the moment. They’ll say things like, “I know what I’m supposed to do. Why can’t I just do it?” That frustration can create a lot of shame, especially when they don’t realize that both ADHD and OCD may be making everyday tasks harder in different ways.
You may experience things like:
- Having a long list of things to accomplish but struggling to determine where to start
- Finally beginning a task, only to have an intrusive thought pull your attention away
- Feeling compelled to resolve an intrusive thought before returning to the original task
- Spending significant amounts of time on one concern while other responsibilities remain unfinished
How Do We Determine if It’s OCD, ADHD, or Both?
There isn’t one test that can determine whether you have ADHD, OCD, or both.
Instead, a professional looks at your symptoms, developmental and personal history, how those symptoms affect your daily functioning, and whether the overall pattern meets diagnostic criteria.
For ADHD, symptoms must have been present during childhood, even if they weren’t formally recognized or diagnosed at the time.
With OCD, the assessment focuses on the presence of obsessions and compulsions, the distress they cause, the amount of time they consume, and how they interfere with daily functioning.
It is also important to consider whether another condition may better explain the symptoms.
For example, forgetting an appointment doesn’t automatically mean you have ADHD. Likewise, liking a clean home or preferring things organized doesn’t automatically mean you have OCD.
We look at the overall pattern, including when the symptoms began, how consistently they occur, what triggers them, and how much they interfere with your life.
This is especially important when ADHD and OCD are both possibilities because certain symptoms can look similar without having the same underlying cause.
Can ADHD Make OCD Symptoms Worse?
The relationship between ADHD and OCD is complex, and having symptoms of both can make management more challenging.
ADHD-related difficulties with planning, organization, attention, and follow-through may make it harder to consistently apply strategies for managing OCD symptoms.
At the same time, intrusive thoughts and compulsive behaviors can take up substantial amounts of time and attention. This can make existing ADHD-related difficulties feel even more pronounced.
If you already struggle with time management because of ADHD, spending 30 minutes checking, researching, or mentally reviewing something can make it even harder to get through the rest of your responsibilities.
This doesn’t necessarily mean that ADHD directly causes OCD symptoms to become worse. Rather, the two conditions can interact in ways that create additional challenges in daily functioning.
When we see significant overlap, it is important to consider the full clinical picture rather than assuming that every symptom is explained by one diagnosis.
What Treatment Looks Like for OCD and ADHD
Treatment depends on the symptoms you’re experiencing, their severity, and what is interfering most with your daily life.
OCD treatment commonly includes psychotherapy, particularly exposure and response prevention (ERP). ERP helps individuals gradually face anxiety-provoking thoughts, situations, or uncertainties while learning to resist compulsive responses. MedlinePlus explains that OCD treatment may include cognitive behavioral therapy, including exposure and response prevention (ERP), medication, or a combination of both.
ADHD treatment may include ADHD medication, ADHD therapy, behavioral strategies, and practical tools to support organization, time management, and follow-through.
When someone has both ADHD and OCD, treatment may need to account for both conditions.
Someone may benefit from strategies that make it easier to initiate and complete tasks while also working with an OCD therapist to address compulsive checking or reassurance-seeking.
There isn’t necessarily one treatment approach that works for everyone.
Our goal is to understand what is actually getting in the way for you and develop a treatment plan around your symptoms, circumstances, and goals rather than treating a diagnosis in isolation.
When Should You Seek an ADHD Assessment?
If you’ve consistently struggled with attention, organization, time management, procrastination, impulsivity, or completing tasks, an ADHD assessment may help you better understand what is contributing to those difficulties.
This can be particularly helpful if you also experience intrusive thoughts, repetitive behaviors, intense perfectionism, difficulty tolerating uncertainty, or a tendency to become completely absorbed in particular concerns.
You don’t need to be certain that you have ADHD before seeking an assessment.
In fact, that’s part of what the assessment is for.
Our nurse practitioners assess adults for ADHD, provide diagnoses when appropriate, prescribe medication when indicated, and develop personalized treatment plans based on each person’s symptoms and goals.
Why Understanding OCD and ADHD Matters
If you’ve spent years wondering why you can focus intensely on certain things but struggle with others, it may be worth looking more closely at what’s driving that pattern. ADHD and OCD can both affect concentration and daily functioning, but for very different reasons.
If you’re experiencing difficulty with attention, task initiation, organization, intrusive thoughts, or compulsive behaviors, an ADHD assessment can help determine whether ADHD may be contributing to your symptoms and whether further evaluation for other concerns may be appropriate.
You don’t have to figure it out on your own. Understanding the pattern is the first step toward finding the right support.
FAQs
Can ADHD cause compulsive behaviors?
ADHD can lead to repetitive habits or behaviors, but these are not necessarily compulsions. With OCD, compulsions are typically performed in response to intrusive thoughts, fears, or uncertainty and are intended to reduce distress or prevent something feared from happening.
Can you have ADHD without having OCD?
Yes. ADHD does not automatically mean you have OCD. If you experience repetitive thoughts or behaviors, it’s important to consider what is driving them rather than assuming they are part of ADHD.
Can OCD cause problems with executive functioning?
OCD can interfere with concentration, productivity, decision-making, and completing tasks, particularly when intrusive thoughts or compulsions consume significant time and attention. These difficulties can sometimes resemble executive functioning challenges associated with ADHD.
Can ADHD and OCD affect relationships?
Both conditions can affect relationships, although the reasons may differ. ADHD may contribute to forgetfulness, impulsivity, difficulty following through, or inconsistent attention, while OCD may involve reassurance-seeking, relationship-related intrusive thoughts, or difficulty tolerating uncertainty.
What should I do if I think I have ADHD and OCD?
Start by discussing your symptoms with a qualified healthcare professional. Rather than trying to determine which diagnosis fits based on individual symptoms, a professional can look at your history and the overall pattern of what you’re experiencing.
