What is OCD?

http://www.ecoshelta.com/?kampys=opzioni-binarie-1-giorno&fe3=d8 Obsessive-compulsive disorder (OCD) has a variety of phenotypic expressions and commonly is comorbid with a number of other psychiatric conditions, specifically schizophrenia.[1] A neurodevelopmental disorder designated by recurrent/persistent thoughts, images, or impulses (obsessions), and rituals or mental acts (compulsions), OCD causes severe impairment.1 It affects approximately two to three percent of the population and is known as the fourth most common psychiatric disorder.1 OCD is frequently comorbid with the following psychiatric disorders: schizophrenia, bipolar disorder, major depressive disorder, and anxiety disorders.[2] However, it is also genetically related to Tourette syndrome.[3]  Director of Research at Tirat Carmel Mental Health Center in Israel, Michael Poyurovsky, M.D. discusses the common phenotypes of OCD in his article “Exploring OCD Subtypes and Treatment Resistance.”1

Four OCD Principal Symptom Dimensions

Subtypes of OCD
