The hallmark of obsessive-compulsive disorder (OCD) is the presence of obsessions and compulsions. It has a bimodal incidence with peaks occurring in late childhood/early adolescence and again in early adulthood (20-29).

The lifetime prevalence of OCD is believed to be between 1% and 3%, and patients can experience chronic or episodic OCD symptoms throughout their lifetime. OCD is a time-consuming and distressing mental state that has higher disability-adjusted years than Parkinson’s disease and multiple sclerosis, combined making OCD one of the top 10 most disabling medical conditions. [1]

OCD is believed to diminish the quality of life of the patient similar in extent to those individuals with schizophrenia. [2]

OCD symptoms are time-consuming and distressing and are often accompanied with strong avoidance behaviours.

OCD is under-recognised, under-treated as well as frequently mistreated. We summarise the key diagnosis and treatment modalities in OCD based on the latest guidelines. [3], [4]
