Generally, diseases outlined within the ICD-10 codes E50-E56 within Chapter IV: Endocrine, nutritional and metabolic diseases should be included in this category. Subcategories This category has only the following subcategory.
Frequently, secondary to thiamine deficiency and subsequent cytotoxic edema in Wernicke encephalopathy, patients will have marked degeneration of the mammillary bodies. Thiamine (vitamin B 1) is an essential coenzyme in carbohydrate metabolism and is also a regulator of osmotic gradient. Its deficiency may cause swelling of the intracellular ...

[1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses.

Glucose deficiencies such as hypoglycaemia reduce available energy for the brain and impair all cognitive processes and performance. [8] [12] [13] Additionally, situations with high cognitive demand, such as learning a new task, increase brain glucose utilization, depleting blood glucose stores and initiating the need for supplementation. [8]
Originally, the term was created to distinguish physical (termed "organic") causes of mental impairment from psychiatric (termed "functional") disorders, but during the era when this distinction was drawn, not enough was known about brain science (including neuroscience, cognitive science, neuropsychology, and mind-brain correlation) for this ...
