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...

Self-Schemas

31.2K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

348
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Taste Buds and Receptors01:20

Taste Buds and Receptors

2.2K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Eating Disorder Research

Background:

  • Most DSM-5 eating disorders correlate with increased suicide risk.
  • The link between Avoidant/Restrictive Food Intake Disorder (ARFID) and suicidal ideation remains under-researched in adults.

Purpose of the Study:

  • To investigate the prevalence of suicidal ideation in an adult sample diagnosed with ARFID.
  • To compare suicidal ideation rates between ARFID patients and those with other eating disorder diagnoses.

Main Methods:

  • A sample of 936 adult eating disorder patients, including 79 with ARFID, participated.
  • The Beck Depression Inventory II Item 9 was used to assess suicidal ideation.
  • Data was collected from patients across various treatment levels (inpatient, residential, PHP, IOP).

Main Results:

  • No statistically significant differences were found in the prevalence of suicidal ideation between participants with ARFID and those with other eating disorder diagnoses.
  • The findings indicate a comparable level of suicidal ideation risk across different eating disorder diagnoses.

Conclusions:

  • Screening for suicidal ideation and risk is essential for all individuals with ARFID, regardless of treatment intensity.
  • Further research with larger adult ARFID cohorts is recommended to validate these findings and explore nuances.
  • Clinical practice should prioritize thorough mental health assessments for ARFID patients.
