[QUOTE="luke11685, post: 252596, member: 15559"] [B]Obsessive–compulsive disorder[/B] ([B]OCD[/B]) is a [URL='https://en.m.wikipedia.org/wiki/Mental_disorder']mental[/URL]and [URL='https://en.m.wikipedia.org/wiki/Abnormality_(behavior)']behavioral[/URL] [URL='https://en.m.wikipedia.org/wiki/Disease#Disorder']disorder[/URL] in which an individual has [URL='https://en.m.wikipedia.org/wiki/Intrusive_thought']intrusive thoughts[/URL] (an [I]obsession[/I]) and feels the need to perform certain routines ([I]compulsions[/I]) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function. Obsessions are persistent unwanted thoughts, mental images, or urges that generate feelings of [URL='https://en.m.wikipedia.org/wiki/Anxiety']anxiety[/URL], [URL='https://en.m.wikipedia.org/wiki/Disgust']disgust[/URL], or discomfort. Some common obsessions include fear of [URL='https://en.m.wikipedia.org/wiki/Contamination']contamination[/URL], obsession with [URL='https://en.m.wikipedia.org/wiki/Symmetry']symmetry[/URL], the fear of acting [URL='https://en.m.wikipedia.org/wiki/Blasphemy']blasphemously[/URL], the sufferer's [URL='https://en.m.wikipedia.org/wiki/Sexual_orientation']sexual orientation[/URL], and the fear of possibly harming others or themselves. Compulsions are repeated actions or routines that occur in response to obsessions to achieve a relief from anxiety. Common compulsions include excessive [URL='https://en.m.wikipedia.org/wiki/Hand_washing']hand washing[/URL], [URL='https://en.m.wikipedia.org/wiki/Cleaning']cleaning[/URL], [URL='https://en.m.wikipedia.org/wiki/Counting']counting[/URL], ordering, repeating, avoiding triggers, [URL='https://en.m.wikipedia.org/wiki/Hoarding']hoarding[/URL], neutralizing, seeking assurance, praying, and checking things. People with OCD may only perform mental compulsions such as needing to know or remember things. While this is sometimes referred to as [URL='https://en.m.wikipedia.org/wiki/Primarily_obsessional_obsessive%E2%80%93compulsive_disorder']primarily obsessional obsessive–compulsive disorder[/URL] (Pure O), it is also considered a misnomer due to associated mental compulsions and reassurance seeking behaviors that are consistent with OCD. Compulsions occur often and typically take up at least one hour per day, impairing one's quality of life. Compulsions cause relief in the moment, but cause obsessions to grow over time due to the repeated reward-seeking behavior of completing the ritual for relief. Many adults with OCD are aware that their compulsions do not make sense, but they still perform them to relieve the distress caused by obsessions. For this reason, thoughts and behaviors in OCD are usually considered [URL='https://en.m.wikipedia.org/wiki/Egosyntonic_and_egodystonic']egodystonic[/URL]. In contrast, thoughts and behaviors in [URL='https://en.m.wikipedia.org/wiki/Obsessive-compulsive_personality_disorder']obsessive-compulsive personality disorder[/URL] (OCPD) are usually considered [URL='https://en.m.wikipedia.org/wiki/Egosyntonic_and_egodystonic']egosyntonic[/URL], helping differentiate between the two. Although the exact cause of OCD is unknown, several regions of the brain have been implicated in its neuroanatomical model including the [URL='https://en.m.wikipedia.org/wiki/Anterior_cingulate_cortex']anterior cingulate cortex[/URL], [URL='https://en.m.wikipedia.org/wiki/Orbitofrontal_cortex']orbitofrontal cortex[/URL], [URL='https://en.m.wikipedia.org/wiki/Amygdala']amygdala[/URL], and [URL='https://en.m.wikipedia.org/wiki/BNST']BNST[/URL].
