Environmental Causes
Some environmental stressors might also be a trigger for obsessive-compulsive disorder in some people with a tendency to developing this condition. For instance, traumatic brain injury in kids and adolescents might be directly linked to a higher risk of this health issue. In fact, up to 30% of people who experienced this brain problem develops signs of obsessive-compulsive disorder within 1 year of the injury. Also, some events or emotions that lead to traumatic or stressful moments would also bring the same effects and cause this mental illness. [10]
