Clinically , is OCD curable or not?

[kenny1999]

Hi all,
1. How is OCD diagnosed? By symptoms told by the patients only? In addition, is there any
equipment or physical checks to confirm OCD ?

2. Clinically, is OCD curable? For "curable", I mean a patient recover totally and no longer need
to revisit the doctor or continue any medicine? Approx. how many % of patients could recover totally and how many years does it take?

3. Clinically and statically is it easy for the return of OCD after recovery?
