What is Obsessive-compulsive disorder (OCD)?

Obsessive-compulsive disorder (OCD) is a mental health condition that is characterized by unwanted and intrusive thoughts (obsessions) and repetitive behaviours (compulsions). These obsessions and compulsions can be time-consuming and interfere with a person's daily life.

Symptoms of OCD

The symptoms of OCD can vary from person to person, but some of the most common include:

  • Obsessions: These are unwanted and intrusive thoughts, images, or urges that repeatedly come into a person's mind. Obsessions can be about anything, but they are often about germs, cleanliness, order, or safety.

  • Compulsions are repetitive behaviours or rituals that a person feels the need to do to reduce the anxiety caused by their obsessions. Compulsions can be simple, such as washing your hands, or more complex, such as checking things repeatedly.

  • Avoidance: People with OCD may also avoid situations they associate with their obsessions. For example, someone with OCD about germs may avoid public bathrooms.

Causes of OCD

The exact cause of OCD is not fully understood, but it is thought to be a combination of genetic and environmental factors. Some of the environmental factors that may contribute to OCD include:

  • Trauma: Some people with OCD have experienced a traumatic event, such as the death of a loved one or a natural disaster.

  • Stress: Stress can trigger or worsen OCD symptoms.

  • Substance abuse: Alcohol and drug use can worsen OCD symptoms.

Treatment for OCD

There are several effective treatments for OCD, including:

  • Cognitive-behavioural therapy (CBT): CBT is a type of therapy that helps people to challenge their negative thoughts and behaviours.

  • Acceptance and commitment therapy (ACT): ACT is a therapy that utilises the strengths of CBT and incorporates mindfulness and modern behavioural theory into the treatment.

  • Exposure therapy: Exposure therapy is a type of CBT that involves gradually exposing people to their feared objects or situations.

  • Medication: Medications, such as selective serotonin reuptake inhibitors (SSRIs), can be used to treat OCD symptoms.
