Obsessive compulsive disorder (OCD)

Also called OCD

Obsessive compulsive disorder (OCD) is a mental health condition where a person has obsessive thoughts and compulsive behaviours. Obsessions are unwanted thoughts, images or urges that keep coming back and cause anxiety. Compulsions are things a person feels they must do or think to ease that anxiety, such as checking, cleaning or counting. It can affect anyone at any age.

What it is

OCD can take up a lot of time and get in the way of daily life, but it can be treated.

The main treatments are a talking therapy called cognitive behavioural therapy (CBT) with exposure and response prevention, and antidepressant medicines. Many people do best with both.

Common signs

  • Unwanted, distressing thoughts that keep returning
  • Repeated checking, washing or counting
  • Needing things in a set order
  • Seeking reassurance often
  • Avoiding situations that trigger thoughts

How it is usually diagnosed

  • Talking with a GP about thoughts and behaviours
  • Assessment by a mental health professional

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Mental health assessment letters
  • Therapy plans and progress notes
  • Medicine lists

Questions to ask your doctor

  • Which treatment do you recommend for me?
  • How long until treatment starts to help?
  • Can I refer myself for talking therapy?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Thoughts of harming yourself or others: get urgent help, call 112 if in danger
