OCD as we commonly call it, is a Neurosis. The patient knows that something is wrong with him / her.
It is defined as,
- An idea,impulse or image which intrudes into the conscious awareness repeatedly.
- It is recognised as one’s own idea, impulse or image but is perceived as ego alien (foreign to one’s personality)
- It is recognised as irrational and absurd (insight is present)
- Patient tries to resist it but is unable to
- Failure to resist,leads to marked distress
Clinically differentiation has to be made from delusion
In delusion, it is recognised as one’s own idea and therefore not resisted. In fact, it is strongly believed that it own’s idea and there not perceived as irrational.
In India, OCD is more common in unmarried males while in most countries there is no gender differences reported.
Studies have shown that life time prevalence is 2% to 3%.
