OCD vs anxiety (and ADHD): how to tell them apart

Worrying constantly, checking things, struggling to focus: these can be signs of anxiety, OCD or ADHD. They overlap, and many people have more than one. But they’re different, and knowing which is which helps you get the right help.

OCD vs generalised anxiety

	Generalised anxiety	OCD
The thoughts	Worries about real-life things: money, health, work, family	Intrusive thoughts, images or urges that often feel alien or senseless
How they feel	Like excessive versions of normal worries	Unwanted, disturbing, “not me”
What you do	Plan, seek reassurance, avoid	Compulsions: rituals, checking, mental neutralising, often in a fixed way
The goal	Prepare for possible problems	Prevent a feared outcome or feel “just right”
Main treatment	CBT, applied relaxation, SSRIs	ERP (exposure and response prevention), SSRIs

The clearest difference is compulsions. In OCD, people feel driven to perform specific actions or mental rituals to relieve anxiety or prevent harm, often in a particular way or a particular number of times.

Anxiety is a big part of OCD, which is why it used to be classed as an anxiety disorder. Since 2013, it has been grouped separately, with related conditions. Our post on generalised anxiety explains anxiety in more detail.

OCD vs ADHD

OCD and ADHD can look similar because both can affect concentration and daily functioning. But the reasons differ:

	OCD	ADHD
Why focus slips	Attention is pulled by intrusive thoughts and rituals	Attention drifts, even when calm
Behaviour	Careful, repetitive, often slow because of checking	Impulsive, restless, quick to move on
Driven by	Anxiety and doubt	Differences in attention and impulse control
When it starts	Often late childhood to young adulthood	In childhood, before age 12
Main treatment	ERP and SSRIs	ADHD medicine, strategies, CBT for ADHD

People can have both, which can make diagnosis trickier. Our post on ADHD vs anxiety explains how ADHD and anxiety overlap.

Why the right diagnosis matters

The most effective treatments differ. ERP, which involves resisting compulsions, is the key therapy for OCD but isn’t the main approach for generalised anxiety. Some general anxiety strategies, like seeking reassurance, can actually feed OCD. And ADHD needs its own treatment.

A doctor, psychologist or psychiatrist can assess what’s going on, often using questionnaires and a detailed history.

When to get help

Talk to a doctor if worry, intrusive thoughts, rituals or focus problems are affecting your work, relationships or daily life. You don’t need to know which it is. That’s what an assessment is for.

Frequently asked questions

Is OCD a type of anxiety?

It used to be classed as an anxiety disorder, and anxiety is central to it. Since 2013, it has its own group, alongside related conditions like body dysmorphic disorder and hoarding disorder.

Can you have OCD and anxiety at the same time?

Yes. Many people with OCD also have generalised anxiety, panic or social anxiety.

Can ADHD be mistaken for OCD?

Sometimes. Both can affect focus and organisation. Some people with ADHD develop rigid routines or checking habits to cope with forgetfulness, which can look like OCD. A careful assessment helps tell them apart.

How do I know if my worries are OCD?

If your worries feel intrusive and unwanted, and you feel driven to do specific rituals or mental acts to relieve them, it may be OCD. Our post on whether you might have OCD has a self-check you can bring to a doctor.
