In this article, I am going to tell you what causes OCD.
The reason I am going to tell you this is because, having searched various forums and health focussed websites, there are still a lot of people out there who do not know what causes OCD.
Some of these people are wracked by guilt as they:

• think they have genetically passed OCD to their children;
• believe their ongoing apparent "irrational" behaviour has influenced other close relatives and family behaviour; and
• they need sound advice as to the exact cause of OCD.
  

In this way, they will get some sort of closure and finally be guided by knowledge and not misinformation.
In this article I am going to summarise what causes OCD into easily understandable segments.
I will also be giving you access to more information later on where you can get help that actually does work.

• OCD is classified as an acute anxiety disorder by the medical profession.
  The anxiety is caused by an obsessive thought (the obsessive component) which cannot be satisfied until something is done in a certain way and repeatedly until anxiety is relieved (the compulsive component).
  
• It appears to be resulting from an abnormal brain pattern particularly in the orbital frontal cortex and the caudate nucleus of the brain.
  These components are associated with perceiving fear and danger and regulation of thoughts and activities respectively.
  Other medical professionals suggest OCD is caused by abnormalities associated with serotonin.
  However, there appears to be ongoing speculation in this department and nothing conclusive at present.
  
• It appears that there is a genetic predisposition to OCD and it has both biological and psychological components associated with it.
  However, the behavioural abnormalities associated with it can be significantly alleviated with correct treatment.
  
• Not all OCD type behaviour is genetic in nature.
  Trauma and stress play a significant role also particularly if there is a tendency to develop the disorder.
  
• In fact, people suffering from depression, bipolar disorder, Tourettes syndrome, body dimorphic disorder, and hair pulling are related to OCD.
  Up to 60% of people suffering from OCD also suffer from depression, so there is a medical connection between them.
  
• OCD is around for a long time (documented back a few centuries) and not just a product of modern society.
  This in one way is comforting to know.
  Due to the stigma associated with OCD, it was not publicly disclosed historically and in many cases is still not openly discussed.
