ABSTRACT

Obsessive-Compulsive Disorder (OCD) is a chronic psychiatric condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). This review aims to synthesize current understanding of the phenomenological aspects of OCD, exploring its clinical presentation, diagnostic criteria, underlying cognitive and neurobiological mechanisms, and treatment approaches. Neuroimaging studies reveal structural and functional abnormalities in brain regions such as the orbitofrontal cortex and anterior cingulate cortex, which are implicated in decision-making, emotion regulation, and error detection. Treatments often include serotonin reuptake inhibitors (SSRIs), anti-dopaminergic drugs, and memantine, supplemented by cognitive-behavioral therapies like Exposure and Response Prevention (ERP). Understanding OCD's phenomenology and neurobiology enhances diagnosis and personalized treatment. Advances in research promise improved management and quality of life for individuals with OCD.
