使用する際の注意点

• The figurative use of the term OCD to refer to someone who exhibits an obsessive tendency is both in widespread usage and considered mostly inaccurate and even offensive by some who consider the use as both reflecting and encouraging misunderstanding of obsessive-compulsive disorder and harming those with the disorder. The idea that being anal is synonymous with OCD is largely misguided, and being punctilious in an egosyntonic way has more in common with OCPD than with OCD, which is egodystonic.
