Obsessive-compulsive disorder (OCD) is often misunderstood as merely being excessively clean or organized, a misconception perpetuated in media and daily conversations. However, OCD is a complex mental health condition that extends far beyond neatness. According to recent research across 10 countries, OCD has a combined lifetime prevalence of 4.1%, and the 12-month prevalence is 3.0%, highlighting a highly persistent course of illness. Notably, more than 80% of OCD cases begin by early adulthood ( Stein et al., 2025 ).
It is important to understand that the stereotypical association between OCD and obsessive cleaning is inaccurate, and such myths can increase stigma and hinder people from recognizing real symptoms and seeking help.
