The lateral hypothalamus (LH), also called the lateral hypothalamic area (LHA), [1] contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; [2] this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature ...
Hypothalamic disease is a disorder presenting primarily in the hypothalamus, which may be caused by damage resulting from malnutrition, including anorexia and bulimia eating disorders, [1] [2] genetic disorders, radiation, surgery, head trauma, [3] lesion, [1] tumour or other physical injury to the hypothalamus. The hypothalamus is the control ...
Aneurysmal subarachnoid hemorrhage may lead to damage of the hypothalamus and the pituitary gland, two areas of the brain that play a central role in hormonal regulation and production. More than a quarter of people with a previous SAH may develop hypopituitarism (deficiencies in one or more of the hypothalamic–pituitary hormones such as ...
Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent feelings of thirst. [1] [2] It involves an increased osmolality or concentration of solute in the urine, which stimulates secretion of antidiuretic hormone (ADH) from the hypothalamus to the kidneys.
[citation needed] As initial stroke symptoms (numbness and tingling) dissipate, an imbalance in sensation causes these later syndromes, characterizing Dejerine–Roussy syndrome. Although some treatments exist, they are often expensive, chemically based, invasive, and only treat patients for some time before they need more treatment, called ...
Males with mild cognitive impairment tend to show more microstructural damage than females with MCI, but seem to have a greater cognitive reserve due to larger absolute brain size and neuronal density. As a result, women tend to manifest symptoms of cognitive decline at lower thresholds than men do. [107]
Some scientists have proposed that damage to this brain region might help explain why some people experience long COVID symptoms, which include: fatigue. brain fog. breathlessness. mental health ...
The certification applies to somatic death, corresponding to death of the person, which has varying definitions but most commonly describes a lack of vital signs and brain function. [9] Death at the level of cells, called molecular death or cell death , follows a matter of hours later. [ 10 ]
