OCD symptoms: the obvious (and the not so obvious)


Although some OCD symptoms are more common, other symptoms can be quite idiosyncratic and often go undetected by inexperienced psychologists.

Turn on your television, and you’re likely to catch at least a fleeting glimpse of obsessive-compulsive disorder (OCD). Many popular TV shows feature characters with OCD (e.g., Emma on Glee, Monk), and it is through this lens that many members of the general population get their first exposure to OCD. Unfortunately, if your understanding of OCD is based solely on depictions in the popular media, you are likely to have a relatively limited (and perhaps, warped) sense of what OCD really is.

The truth is that OCD can manifest in many different ways. Although some symptoms are more common (e.g., a fear about about germs or getting sick), other symptoms can be quite idiosyncratic and often go undetected by inexperienced psychologists. The unfortunate consequence of this is that many people with OCD don’t know that they have OCD. Instead of recognizing their symptoms as being related to OCD, they blame themselves for their symptoms. They think that the reason they have scary or unacceptable thoughts is because they are not as “good” or as “moral” as they should be. This could not be further from the truth. In my work as a clinical psychologist, I have learned that most individuals with OCD are exactly the types of people that you would want as friends or family members. They are good, honest, hardworking people who are bombarded by near constant thoughts that are unwanted and horrifying. These thoughts often prevent them from living the lives they so desperately want for themselves and for their families. There is nothing more rewarding as a therapist than helping these individuals fight their OCD and reclaim their lives as their own.

Below, I have included some categories of symptoms associated with OCD. Some of these symptoms are common, whereas others are more unusual. If you or a loved one have any of these symptoms and they are affecting your quality of life, please consider consulting with a psychologist experienced in treating OCD. Exposure and response prevention (ERP) is a highly effective treatment for OCD, and it can help you reclaim the life you deserve.
