When OCD and ADHD meet…
One pattern I have noticed in clients with both OCD and ADHD is an internal tug-of-war between the two conditions.
The OCD may generate frightening “what-if” scenarios and then demand a compulsion to prevent the feared outcome. These compulsions are not always small or simple. They may involve multiple steps, extensive checking, detailed planning or broad instructions such as, “Make sure this never happens again.”
For an ADHD system, these large, complex or vague demands can be difficult to organise, begin and sustain. A brief compulsion may be completed easily, but more demanding compulsions involving study, work, relationships, social situations or preventing harm may be procrastinated, avoided or interrupted by distraction.
For example, OCD might demand that someone carefully review an entire assignment several times, check every reference, compare it against the marking criteria and seek reassurance before submitting it. Without significant ADHD-related barriers, the compulsive part may blend more fully and take control of the process. The person may complete the entire checking routine, despite the time and distress involved. This can resemble a more typical OCD presentation in which the compulsion is consistently carried out to reduce anxiety or obtain certainty.
When ADHD is also present, the same person may feel intensely driven to complete the routine but struggle to begin it, lose focus partway through or avoid it because it feels too large and exhausting. They may then submit the assignment late, overlook something or not submit it at all.
When the compulsion is not completed and a mistake or other consequence occurs, OCD may use this as evidence that the original fear was justified and that even more vigilance is required next time. I often notice a strong inner critic developing around this cycle, bringing guilt, shame and self-blame about what was not done or what should have been prevented.
This can make both conditions harder to recognise. The person may appear highly diligent, cautious and controlling in some areas, while seeming avoidant, overwhelmed or inconsistent in others. What I often see underneath is a struggle between OCD demanding greater control and ADHD making those demands increasingly difficult to carry out.
