October is a month with several significant campaigns that help educate and grow awareness about mental health and mental illness. Among them is International OCD Awareness Week, which takes place Oct. 9–15. Immediately following Mental Illness Awareness Week, International OCD Awareness Week was launched in 2009 to raise awareness of obsessive-compulsive disorder (OCD), increase understanding of how OCD affects people and help reduce stigma around OCD.
As Dr. Eric Storch, professor and McIngvale Presidential Endowed Chair at the Baylor College of Medicine, notes, "[OCD] is the experience of unwanted, intrusive thoughts, images or impulses that bring about stress and anxiety, which motivate a behavioral response, called compulsions. These behavioral responses can be things you see, like washing your hands repetitively; or things that you don’t see, like avoiding things that make you uncomfortable."
Let's take a look at 15 facts and statistics about obsessive-compulsive disorder.
