- For an OCD diagnosis, the individual needs to show obsessions, compulsions, or both.
- The obsessions, compulsions, or both need to be interfering with their life.
- Rule out common conditions: anxiety disorders, delusions, PTSD, suicidal or homicidal ideation, and other medical conditions.
- Assess the sudden onset of OCD symptoms to rule out medical conditions, such as autoimmune disorders.
- Separate between true risk of harm and OCD, especially in perinatal OCD.
