ADHD and OCD: can you have both?
Yes, you can have both ADHD and OCD. They are different conditions, but they can overlap, affect each other, and sometimes be mistaken for one another. This article explains the differences, the overlap, and what to do if you think you may have both.
If you have symptoms that feel confusing or contradictory, a proper assessment can help clarify what is driving them and what treatment may help.
Can you have both ADHD and OCD?
Yes. ADHD and OCD can occur in the same person, and this is not unusual. ADHD is a neurodevelopmental condition linked to attention, impulsivity, and executive function, while OCD is an anxiety-related condition marked by intrusive thoughts and compulsive behaviours.
Having one condition does not rule out the other. In fact, some people only get the full picture after noticing that symptoms do not fit neatly into one diagnosis.
What is the difference between ADHD and OCD?
ADHD mainly affects attention, organisation, impulsivity, and activity levels. OCD mainly involves intrusive, unwanted thoughts and repeated behaviours or mental rituals done to reduce anxiety.
The key difference is often the reason behind the behaviour. With ADHD, a person may lose focus, forget tasks, or act impulsively without planning. With OCD, a person may repeat actions because they feel driven by fear, doubt, or the need for things to feel “right”.
ADHD symptoms
Common ADHD symptoms include:
Difficulty sustaining attention.
Disorganisation.
Forgetfulness.
Restlessness.
Impulsivity.
Losing things.
Difficulty starting or finishing tasks.
These symptoms often affect work, home life, and time management. They may be present most of the time rather than only in response to specific fears or thoughts.
OCD symptoms
Common OCD symptoms include:
Intrusive thoughts.
Repetitive checking.
Cleaning or washing rituals.
Mental counting or repeating.
Needing reassurance.
Fear of harm, contamination, or mistakes.
Distress if routines are interrupted.
OCD is usually driven by anxiety and the urge to prevent something bad from happening. The repetitive behaviour may bring only short-term relief.
Where ADHD and OCD overlap
ADHD and OCD can both involve poor concentration, mental overload, and difficulty completing tasks. A person with ADHD may appear distracted because their mind moves quickly, while someone with OCD may appear distracted because intrusive thoughts keep interrupting them.
Both conditions can also lead to frustration, shame, and exhaustion. This is one reason they are sometimes mistaken for each other or missed when only part of the picture is considered.
How to tell them apart
It can help to look at the reason behind the behaviour.
ADHD is usually about inattention, impulsivity, and difficulty regulating focus or action.
OCD is usually about anxiety, intrusive thoughts, and compulsions to reduce distress.
For example, repeatedly checking a door could be OCD if it happens because of fear that something terrible will happen. It could be ADHD if the checking happens because the person is forgetful or unsure they completed the task.
In real life, the boundary is not always simple. Some people have both conditions, which makes professional assessment especially useful.
How each condition affects the other
ADHD can make OCD harder to manage because it may be more difficult to resist compulsions, follow routines, or use coping strategies consistently. On the other hand, OCD can make ADHD symptoms feel worse because constant worry and rituals take up time, energy, and attention.
When both are present, daily life can become more complicated. A person may feel stuck between acting impulsively and feeling driven to repeat behaviours until things feel safe or correct.
Treatment when both are present
Treatment needs to be tailored carefully when ADHD and OCD occur together. A clinician may need to decide which symptoms are most severe, which condition is causing the most impairment, and what to treat first.
Treatment may include:
Psychological therapy, such as CBT and exposure and response prevention for OCD.
ADHD medication review, if ADHD symptoms are significantly affecting daily life.
Support for sleep, routines, stress, and executive functioning.
Specialist referral if symptoms are complex or severe.
It is important to tell your clinician about both sets of symptoms, even if one feels more obvious than the other. Treating only one condition may leave the other untreated and still causing difficulties.
Medication considerations
If you have both ADHD and OCD, medication choices may need extra care. Some people worry that ADHD medication could worsen OCD symptoms, while others find that treating ADHD helps them cope better overall.
There is no single rule that applies to everyone. A prescriber will usually consider your full history, current symptoms, and any previous reactions to treatment before recommending a plan.
When to seek a second opinion
A second opinion can be helpful if:
Your symptoms do not seem to fit one diagnosis.
Treatment has not helped as expected.
You feel your concerns have been dismissed.
You suspect both ADHD and OCD, but only one has been explored.
You have had a diagnosis, but the treatment plan still does not make sense.
If your symptoms are affecting work, relationships, or your mental health, it is reasonable to ask for another review. A fresh assessment can sometimes uncover a missed overlap or a different explanation.
