Obsessive Compulsive Disorder (OCD) affects about 1 in 50 people in the U.S., characterized by obsessions (repetitive thoughts) and compulsions (repetitive behaviors) that vary in severity. Diagnosis involves evaluating the presence of disturbing thoughts, the unrelenting need to perform tasks, and the impact on daily life. Treatment can include therapy, medication, and lifestyle adjustments depending on the severity of the individual’s symptoms.
