Co-morbidities associated with OCD

comorbidities associated with obsessive compulsive disorder

Comorbid disorders are seen in up to 75% of patients with OCD (1)

Some common comorbid conditions seen in OCD patients include:

• paediatric population
  • Attention deficit disorder (ADHD)
  • disruptive behavior disorders
  • major depression
  • other anxiety disorders
    
    
• adult population
  • depression
  • social phobia and other specific phobias
  • alcohol misuse
  • generalised anxiety disorder
  • other related obsessive-compulsive disorders such as body dysmorphic disorder

Furthermore OCD is more common than would be expected in people with

• schizophrenia - in about 10%
• bipolar disorder - in about 10%
• anorexia and bulimia nervosa - in about 20%
• Tourette’s disorder - in about 20% (2)

In addition, comorbid conditions in a patient play a role in predicting quality of life (QoL) more so than OCD severity itself in both children and adults (1).
