Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.6K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Introduction to Psychological Disorders01:19

Introduction to Psychological Disorders

963
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...

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...

Summary

Functional body disorders arise from dysregulated control and perception, not organ abnormalities. New guidelines offer pragmatic approaches for treating these common conditions, improving patient trust and outcomes.

Area of Science:

  • Medicine
  • Physiology

Background:

  • Functional disorders lack clear bio-morphological organ-level definitions.
  • They stem from higher-level organismal dysregulation in control and perception.
  • These disorders can affect any system under stress and are seen in veterinary medicine.

Purpose of the Study:

  • To address the diagnostic challenge posed by the incongruence between organic findings and reported symptoms in functional disorders.
  • To emphasize the need for a clear explanatory model to foster patient trust and treatment adherence.
  • To introduce the S3 guidelines for functional disorders.

Main Methods:

  • Review and synthesis of current understanding of functional disorders.
  • Analysis of diagnostic challenges in primary care.
  • Incorporation of information from the new S3 guidelines on functional disorders.

Main Results:

  • Functional disorders are characterized by dysregulated control processes and altered perception.
  • The "incongruence" between physical findings and symptoms is a key diagnostic hurdle.
  • The S3 guidelines offer constructive, pragmatic information for patient treatment.

Conclusions:

  • A comprehensive explanatory model is crucial for effective patient management.
  • The S3 guidelines provide practical tools for healthcare providers.
  • Addressing functional disorders requires a focus on superordinate regulatory mechanisms rather than solely organ pathology.
