Obsessive-Compulsive Disorder (OCD) is a chronic mental health condition marked by recurring, unwanted thoughts (obsessions) and repetitive behaviors (compulsions) performed to ease distress. It severely impacts daily life, interfering with work, relationships, and activities. OCD’s causes are complex, involving genetic, biological, environmental, and psychological factors. Symptoms often include fears of contamination, harm, or disorder, and ritualistic behaviors like excessive cleaning or checking. Despite its debilitating nature, effective treatments, including therapy and medication, can significantly improve symptoms.
