Summary
Pagophagia, or compulsive ice eating, is linked to iron deficiency and may improve attention. Iron replacement therapy is the standard treatment for this eating anomaly.
Area of Science:
- Physiology
- Neuroscience
- Eating Disorders
Background:
- Pagophagia, the compulsive consumption of ice, is a recognized eating anomaly often associated with iron deficiency.
- Current treatment involves iron replacement therapy, addressing the underlying nutritional deficit.
Purpose of the Study:
- To review the physiological characteristics of pagophagia.
- To explore the potential neurobehavioral effects of ice consumption.
Main Methods:
- Review of existing studies on pagophagia and iron deficiency.
- Analysis of research on the physiological responses to cold stimuli in the mouth.
Main Results:
- Iron-deficient individuals showed impaired attention, which improved with ice consumption compared to water.
- Cold stimuli ingestion can increase cerebral blood flow velocity and oxygen supply to the brain.
Conclusions:
- Pagophagia may enhance attention through mechanisms involving increased cerebral blood flow.
- Further research is warranted to investigate the neurobehavioral impact of cold stimuli ingestion in humans and animals.

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.

1.7K
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,...

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

32
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...

377
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...
