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...
Dimensions of Health and Illness01:21

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
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 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...
Classification of Illness01:17

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe and...
Bipolar Disorder01:30

Bipolar Disorder

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Mental Health Research

Background:

  • Traditional psychiatric diagnosis relies on categorical classifications.
  • Growing evidence suggests symptom dimensions and overlaps challenge discrete diagnostic boundaries.
  • A dimensional perspective offers a more nuanced understanding of mental illness.

Purpose of the Study:

  • To explore the concept of a 'mental illness spectrum'.
  • To examine symptom severity within single disorders and symptom overlap between disorders.
  • To provide clinical examples supporting a dimensional approach.

Main Methods:

  • Review of clinical observations and case examples.
  • Conceptual analysis of psychiatric diagnostic models.
  • Literature review on dimensional approaches in psychiatry.

Main Results:

  • Clinical cases illustrate symptom continuity within disorders.
  • Observed symptom constellations suggest significant overlap between different mental disorders.
  • These findings support a spectrum model of mental illness.

Conclusions:

  • A dimensional approach, viewing mental illness as a spectrum, is clinically relevant.
  • This perspective enhances understanding of symptom severity and inter-disorder symptom sharing.
  • Further research into dimensional models may refine psychiatric diagnosis and treatment.
