Obsessive-Compulsive Disorder is defined primarily by which of the following?

Obsessive-Compulsive Disorder (OCD) is characterized predominantly by the presence of persistent, unwanted thoughts, also known as obsessions, and the urge to carry out specific behaviors or rituals, referred to as compulsions. Individuals with OCD often feel driven to perform these actions to alleviate the anxiety generated by their obsessive thoughts, even if they recognize that their obsessions are irrational. This core feature sets OCD apart from other mental health disorders, as the repetitive thoughts and actions are central to the diagnosis and experience of those affected.

The other choices, while they describe symptoms of different mental health conditions, do not encompass the defining characteristics of OCD. Intense episodes of depression typically relate more to mood disorders, compulsive eating aligns with eating disorders, and severe anxiety leading to panic attacks is commonly associated with anxiety disorders. Thus, the defining elements of obsessions and compulsions truly capture the essence of Obsessive-Compulsive Disorder.
