Gender differences in the symptoms and physiological basis of Obsessive-Compulsive Disorder

Abstract

Obsessive-compulsive disorder (OCD) is an anxiety disorder related to repetitive behaviors and intrusive thoughts. Individuals with OCD experience conscious, self-imposed compulsions and counter-compulsions, which result in high levels of anxiety and difficulties in social interactions. OCD is a common mental disorder with onset often in adolescence. Gender differences in OCD exist, with males reporting earlier symptom onset, and females experiencing symptoms during adolescence, pregnancy, or postpartum, particularly related to contamination and/or aggressive obsessions. Neurobiological factors play a role in OCD etiology. Genetic studies show hereditary tendencies, with gender differences observed. Brain structure research identifies differences between male and female patients. Dopamine and plasma norepinephrine are implicated in OCD pathogenesis. Understanding gender differences is crucial for OCD diagnosis and treatment. Further research is needed to validate and explain these differences in order to inform advancements in OCD treatment approaches. This paper summarizes and discusses the relationship between OCD and gender, focusing on epidemiological characteristics, symptoms, and physiological basis of OCD, emphasizing gender differences. Future research directions in the field of OCD are presented.
