Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

720
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-Compulsive

526
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...

Anxiety: Overview

1.2K
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.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

978
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.

Borderline Personality Disorder01:25

Borderline Personality Disorder

754
Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Psychosexual Stages of Personality: Anal01:26

Psychosexual Stages of Personality: Anal

4.5K
Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...

Summary
This summary is machine-generated.

Obsessive-compulsive disorder (OCD) patients show impaired planning ability, needing more time and making more errors on complex tasks. This suggests working memory deficits may underlie planning difficulties in OCD.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Psychiatry

Background:

  • Executive dysfunction is central to obsessive-compulsive disorder (OCD).
  • Previous research on planning ability (PA) deficits in OCD has yielded inconsistent findings.
  • Understanding PA in OCD is crucial for explaining cognitive impairments.

Purpose of the Study:

  • To clarify planning ability (PA) deficits in obsessive-compulsive disorder (OCD) patients.
  • To investigate the relationship between PA, impulsivity, and clinical variables in OCD.
  • To explore the specific planning sub-components affected in OCD.

Main Methods:

  • Assessed 68 OCD patients and 68 healthy controls (HCs) using the computerized Stocking of Cambridge (SoC) task.
  • Examined planning sub-components across varying task difficulties (2-5 moves).
  • Analyzed initial thinking time and accuracy rates between groups.

Main Results:

  • OCD patients exhibited longer initial thinking times for low-demand tasks (2-3 moves) but similar accuracy to HCs.
  • OCD patients showed longer initial thinking times and significantly worse accuracy for high-demand tasks (4-5 moves).
  • No significant association was found between impulsivity and planning ability in OCD patients.

Conclusions:

  • OCD patients struggle with retaining planned sequences, necessitating task re-planning.
  • Working memory deficits may significantly influence planning ability in OCD.
  • Further research should explore the interplay between working memory, PA, and clinical factors in OCD.
