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...
Binge Eating Disorders01:23

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Introduction to Biological Bases of Psychology

Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...
Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
Horney's Sociocultural Approach01:27

Horney's Sociocultural Approach

Karen Horney's psychoanalytic theories emphasize the potential for self-realization and the importance of addressing social and cultural, rather than biological, factors in personality development. She challenged traditional Freudian views, particularly Freud's concept of "penis envy," which she argued stemmed from cultural influences rather than inherent biological differences. Horney believed that any sense of inferiority in women was a result of societal conditioning, such as dependence on...

Area of Science:

  • Psychiatry
  • Psychology
  • Neuroscience

Background:

  • Hoarding disorder is often viewed as a variant of obsessive-compulsive disorder (OCD).
  • Emerging research indicates significant overlap with other conditions, including attention deficit-hyperactivity disorder (ADHD), organic brain disease, depression, anxiety, personality disorders, and impulsivity.
  • Understanding these complex relationships is crucial for effective intervention.

Purpose of the Study:

  • To provide a practice-friendly review of hoarding conceptualization and treatment.
  • To integrate findings from biological and psychological research.
  • To highlight the multifaceted nature of hoarding disorder.

Main Methods:

  • Review of current biological and psychological research on hoarding.
  • Analysis of conceptual frameworks for understanding hoarding.
  • Examination of familial, environmental, cognitive, and behavioral factors.

Main Results:

  • Hoarding exhibits complex overlaps with ADHD, depression, anxiety, and personality disorders, extending beyond its traditional association with OCD.
  • Key contributing factors include familial and environmental vulnerabilities, maladaptive cognitive processes, maladaptive cognitive content, and maladaptive behavioral patterns.
  • Treatment efficacy varies, with several promising clinical practices identified.

Conclusions:

  • Hoarding disorder is a complex condition with diverse etiologies and symptom presentations.
  • A comprehensive approach integrating biological and psychological perspectives is necessary for effective treatment.
  • Ten promising clinical practices offer potential for improved patient outcomes.
