How far things have come! It has been a bumpy ride, to say the least. Nonetheless, a tremendous amount of progress has been made in understanding and treating OCD. Since 1980 progress has accelerated.
What happens from here? Of course, no one knows. Maybe it will be a breakthrough in genetic research or maybe something else. Will there be another paradigm shift? There have been so many, it would be unwise to bet against it.
That's the end of this history of OCD.
