Anorexia Nervosa

Anorexia Nervosa

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.

Bulimia Nervosa

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...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Hypothyroidism II: Pathophysiology

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

Hypothalamic-Pituitary Axis

Hypothalamic-Pituitary Axis

The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Background:

Anorexia, or poor appetite, is a symptom in diverse conditions like anorexia nervosa and cachexia.
The hypothalamus, specifically arcuate nucleus neurons (AGRP/NPY and POMC/CART), is crucial for appetite regulation.
The anorectic anx/anx mouse model exhibits hypothalamic abnormalities relevant to appetite control.

Purpose of the Study:

To review hypothalamic abnormalities in the anorectic anx/anx mouse.
To explore the link between hypothalamic dysfunction and appetite regulation disorders.
To discuss the role of mitochondrial dysfunction and inflammation in anorexia.

Main Methods:

Review of hypothalamic aberrances in the anx/anx mouse model.
Analysis of neuropeptidergic and neurotransmitter systems.
Examination of data from other animal models and clinical studies.

Main Results:

The anx/anx mouse shows selective hypothalamic degeneration and inflammation.
These hypothalamic changes are associated with mitochondrial dysfunction.
Aberrant hypothalamic function, neurogenesis, and mitochondrial issues are linked to disturbed food intake regulation.

Conclusions:

Hypothalamic inflammation, degeneration, and mitochondrial dysfunction are key factors in anorexia.
These mechanisms contribute to the disturbed regulation of food intake observed in various conditions.
Understanding these hypothalamic pathways is vital for addressing anorexia.
