Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
Personality Disorders: Dependent and Obsessive-Compulsive01:24

Personality 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...
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Anxiety: Overview01:18

Anxiety: Overview

Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Neuroscience

Background:

  • Obsessive-compulsive disorder (OCD) is recognized as a heterogeneous condition.
  • Clinical manifestations of OCD are complex and variable.

Purpose of the Study:

  • Compare clinical and demographic characteristics of early-onset OCD (EOG) versus late-onset OCD (LOG).
  • Compare early-onset OCD with and without tic disorders.
  • Investigate the impact of age of onset and tics on comorbidity patterns.

Main Methods:

  • Evaluated 330 outpatients meeting DSM-IV criteria for OCD.
  • Classified patients into early (before 11), intermediate, and late (after 18) onset groups.
  • Utilized Yale-Brown Obsessive Compulsive Scale, Dimensional Yale-Brown Obsessive Compulsive Scale (DY-BOCS), Yale Global Tics Severity Scale, and Structured Clinical Interview for DSM-IV.

Main Results:

  • Early-onset OCD (EOG) showed more males, higher family history of OCS, and higher DY-BOCS scores.
  • EOG had higher scores in "aggression/violence" and "miscellaneous" dimensions.
  • EOG without tics had higher global DY-BOCS and "contamination/cleaning" dimension scores.

Conclusions:

  • The study clarifies clinical distinctions between early-onset OCD with and without tics.
  • Age of onset and tic comorbidity are significant factors in OCD heterogeneity.
