As an individual who has struggled with OCD for 45 years, I felt compelled to validate some of the comments that made a distinction between behavior attributed to OCD (such as idiosyncrasies, quirks or phobias) and the repetitive rituals of the OCD sufferor. OCD rituals, such as checking locks or washing hands are a response to an unreasonable fear. The best way I can describe the disorder is that when engaging in a particular ritual, one's brain is akin to a skipping record. And, although the person with OCD is quite aware that their concerns are irrational, it takes an extraordinary effort to stop their current episode of 'brain skipping.' Which takes me to the subject of medication. Ten years ago I was introduced to Zoloft, an SSRI (serotonin reuptake inhibitor). For those of you who can remember, Zoloft was the proverbial coin placed on the record player needle. No more skips.
