Summary
Disordered eating behaviors are reported in neurodegenerative diseases like Alzheimer's and Parkinson's. Further research and standardized screening tools are needed for better patient care.
Area of Science:
- Neurology
- Psychiatry
- Public Health
Background:
- Neurodegenerative diseases and disordered eating are growing research areas.
- Limited research exists on the connection between neurodegenerative diseases and disordered eating.
Purpose of the Study:
- To synthesize evidence on disordered eating behaviors in individuals with neurodegenerative diseases.
- To identify patterns and tools used in studying eating behaviors within neurodegenerative conditions.
Main Methods:
- A scoping review using the Joanna Briggs Institute methodology.
- Systematic search across four databases.
- Narrative descriptive analysis of 36 evidence sources.
Main Results:
- Overeating (hyperphagia) noted in dementia/Alzheimer's studies.
- Appetite changes prevalent in ALS and dementia.
- Food addiction/binge eating in Parkinson's; eating disorders in Multiple Sclerosis.
- 53% of studies used validated or unvalidated tools to assess eating behaviors.
Conclusions:
- Disordered eating behaviors are present across various neurodegenerative diseases.
- Further research is needed to understand the causes and mechanisms.
- Standardized assessment tools and routine screening are recommended for early diagnosis and care.

1.1K
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...

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...

2.0K
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

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,...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

1.7K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
