Obsessive Compulsions and Autism

Causes

The exact cause of Obsessional Compulsive Disorder (OCD) in people who are on the autism spectrum is unknown, but it is probably caused by a combination of factors.

• OCD, like some forms of autism spectrum disorder, tends to run in families. There is evidence that OCD is more prevalent in the families of some people with autism spectrum disorders. (Abramson, 2005; Bolton, 1995; Delorme, 2007; Hollander, 2003; Kanno, 2004)

• OCD may be due to a lack of the brain chemical serotonin. Low levels of serotonin may also be related to some autistic spectrum disorders. (Gross-Isseroff R, 2001).

• Stress does not appear to cause OCD. However, a stressful event or trauma seems to trigger the condition in some people. (NAS, 2006 – 2).

• Personality type may also be a factor. For example, perfectionists seem to be more prone to developing OCD. (NAS, 2006 – 2)
