Most people know that Exposure Response Prevention (ERP) is the main intervention used for Obsessive Compulsive Disorder (OCD). So the rationale is pretty simple here, say we have a patient who is afraid of contamination (obsession) and wash his hands excessively (compulsion), we do some preparation work and can then start the ERP by exposing him to dirt without letting him to wash his hands (response prevention). This is normally done on a very gradual manner (with the patient’s consent and enough preparation work beforehand, so it is definitely not forcefully done to him). And of course in reality the OCD cases are barely as straightforward and simple as this, but this is the general principle.
With pure obsession, i.e. those without any compulsive behaviour, it’s all in their minds, things can get a bit harder, but still, it’s possible. Some commonly seen pure-O are (1) relationship obsessions (discussed in my blog else where as “morbid jealousy” which might or might not be the same condition), (2) sexual obsessions, (3) religious obsessions, (4) violent obsessions, (5) neutral obsessions.
So let’s take a recently seen man as an example here. It started once when he drove past a church, and somehow a sexual related thought popped out in his mind, he couldn’t bear himself having such “dirty” thought in a holy place, and since then, whenever he goes passed any holy places, he will suppress his mind from coming out with any “dirty thoughts”. And as we all know that our minds don’t work this way, the more you try to push some thoughts away, the more they bounce back and pop up.
ERP is possible for such pure-O cases. After the initial preparation work including psychoeducation and relaxation training, they are exposed to those thoughts that they have been avoiding, in those places (based on the items in the hierarchy). So it works similarly for all different types of pure obsessions, be it relationship, violent, religious or sexual (in certain cases where direct exposure is not possible, it will have to be done in imagination, and by watching videos etc).
However, how about neutral obsessions? What the patient has could be some really simple, random thoughts, which might be inconsistent, but they might be spending hours and hours thinking about these random stuff. Like a young man I saw couple months ago, who reacts to any thought his mind comes up with, e.g. “why does the universe work this way?”, “how do my ears listen and my brain comprehend what others say?” etc. I couldn’t really carry out typical ERP to him, since those are really random topics and they can be completely different every time. So I needed him to start thought defusion exercises, mindfulness meditation (then he dropped out…). I believe this is the best way for neutral pure-O, though I understand how difficult it’s to increase their motivation to keep practicing until they see the effects (did have patients in the past who were surprised by how quiet their minds can be after such exercises – and this is just a bonus, as it’s not the intention or purpose of such practices).
Do enlighten me if you have better psychological intervention for neutral pure-O. And I hope all the OCD sufferers out there will not give in to the illness!
