Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
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.

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
Introduction to Psychological Disorders01:19

Introduction to Psychological Disorders

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...
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...
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...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • Tic disorders encompass a range of conditions characterized by involuntary motor and vocal behaviors.
  • Current diagnostic criteria, particularly for the Diagnostic and Statistical Manual of Mental Disorders (DSM), require refinement for clarity and consistency.
  • The category of 'tic disorder not otherwise specified' is frequently used, indicating a need for improved diagnostic specificity.

Purpose of the Study:

  • To review key issues relevant to the nosology of tic disorders.
  • To propose preliminary recommendations for the diagnostic criteria of tic disorders in the DSM-V.
  • To enhance diagnostic clarity and reduce reliance on residual diagnostic categories.

Main Methods:

  • Focused review of existing literature and clinical practice regarding tic disorder classification.
  • Development of specific recommendations for revising diagnostic criteria based on the review.
  • Consideration of the impact of proposed changes on clinical practice and research continuity.

Main Results:

  • Proposed a more precise definition for motor and vocal tics.
  • Recommended simplification of the duration criteria for diagnosing tic disorders.
  • Suggested revising the 'transient tic disorder' classification and establishing new categories for substance-induced and medically-induced tics.
  • Advocated for 'motor tic only' and 'vocal tic only' specifiers for chronic tic disorders.

Conclusions:

  • The proposed revisions aim to clarify and simplify the diagnosis of tic disorders.
  • These changes are intended to reduce the use of unspecified diagnostic categories without substantially altering clinical practice.
  • The recommendations support improved diagnostic accuracy and consistency for tic disorder research and clinical application.
