Summary
Obsessive-compulsive disorder (OCD) is debated for reclassification from anxiety disorders to obsessive-compulsive spectrum disorders (OCSDs). This review examines evidence to determine OCD's appropriate diagnostic placement.
Area of Science:
- Psychiatry
- Neuroscience
- Clinical Psychology
Context:
- Current diagnostic systems classify obsessive-compulsive disorder (OCD) as an anxiety disorder.
- Emerging research suggests similarities between OCD and obsessive-compulsive spectrum disorders (OCSDs) in symptoms, illness course, and neurocircuitry.
- The DSM-5 considered reclassifying OCD, adding specific measures for related disorders.
Purpose:
- To review the evidence supporting the classification of OCD within anxiety disorders versus OCSDs.
- To critically evaluate the relationship between OCD, OCSDs, and anxiety disorders.
- To address the ongoing controversy regarding the diagnostic placement of OCSD symptoms.
Summary:
- Evidence from comorbidity, family, and neurological studies suggests potential links between OCD and OCSDs.
- Recent findings, however, also support the current association of OCD with other anxiety disorders.
- The review investigates the complex relationship to determine OCD's definitive diagnostic category.
Impact:
- This review informs the ongoing debate on psychiatric diagnostic classification.
- Findings contribute to a better understanding of the neurobiological and clinical underpinnings of OCD and related disorders.
- Clarifying OCD's classification may impact future diagnostic criteria and treatment approaches.

Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

01:24Personality Disorders: Dependent and Obsessive-Compulsive
Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.
Dependent Personality Disorder
Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle with...

01:30Generalized Anxiety Disorder
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...
01:28Social Anxiety Disorder
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.
01:27Panic Disorder
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
