<p>Your information is basically sound. Serotonin and dopamine are both neurotransmittors that are connected, in different ways, with positive feelings or elevated mood.

The role of dopamine in obsessive-compulsive disorder: preclinical and clinical evidence</a>). From what I have read, research on this subject has led to the use of antipsychotics in treatments, in particular in cases where patients don't respond well to SSRIs (antidepressents) alone. </p>

Thank you! Makes a lot more sense and will definitely result in me doing some more research, I appreciate it!

This is a somewhat ... old-fashioned take on neuromodulators and their role in mood disorders. Dopamine as coding reward, serotonin as directly modulating mood ...

@jona I feel the same way, but I think that there's enough of a basis for further study if the OP wants to pursue it at a research level.  I think it certainly addresses the question well.  I would love it (could be a bounty in it for ya!) if you would elaborate on the current work in the field.

<p>I understand that OCD is something that causes sufferers to perform irrational behavour consciously, I also understand that the motivation comes from performing the irrational behaviour/behaviours to release the anxiety experienced. </p>

<p>Although, what causes sufferers to pursue specific goals whether it be career choice, physical achievement, etc. ?

I wonder at the soundness of your theory that OCD patients tend towards high achievement. OCD appears across the socioeconomic spectrum, in scenarios from hoarding to germophobia. There is also a difference between anxiety in high achievers and OCD. Many researchers believe OCD decreases the chance of high achievement.

Mental Health (www.nimh.nih.gov/) has a lot about this.

Sorry, I should have been more clear. I was associating high achievement with extensive work towards a specific goal in which they tend to reach. For example, hoarders achieve maximum retainment of their specified object/objects of interest, or what they'd like to believe is maximum, in order to satisfy their neurological and emotional needs. High achievement doesn't always necessarily have to be accepted, and can sometimes be frowned upon, or infamous. I know very little on this subject, and I appreciate your provided link, I'll check it out straight away! Thank you @anongoodnurse
