How is it Diagnosed?
Obsessive Compulsive Disorder (OCD) is diagnosed through clinical evaluation using
standardized psychiatric tools and criteria, primarily those outlined in the DSM-5
(Diagnostic and Statistical Manual of Mental Disorders). The core features include the
presence of obsessions (recurrent, intrusive, and distressing thoughts) and/or
compulsions (repetitive behaviors or mental acts performed to alleviate anxiety).
Diagnosis involves a detailed psychiatric interview exploring symptom onset, frequency,
duration, and the degree to which they interfere with daily functioning. Patients often
recognize the irrationality of their thoughts and actions, but feel powerless to stop
them. Common obsessions include fears of contamination, symmetry, or harm;
compulsions may involve washing, checking, or counting rituals.
The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is a widely used tool to assess
the severity and type of symptoms. It provides a score that helps monitor treatment
progress over time.
A thorough assessment is conducted to differentiate OCD from other mental health
conditions like generalized anxiety disorder, depression, or psychosis. Comorbidities are
common and must be evaluated. Neurological and physical examination may be done if
secondary causes (like PANDAS in children) are suspected.
Early diagnosis and intervention with cognitive behavioral therapy (CBT) and/or
medication (typically SSRIs) lead to better outcomes and improved quality of life.
