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 ...
Damage to the lateral hypothalamus can also lead to aphagia, as seen in the 1978 study by Timothy Schallert and Ian Whishaw. [3] Other causes might be due to depression, cervical spine disease and conversion disorders. It is important to note that all these causes (except due to the damage of the lateral hypothalamus) are indirect.
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.
The various signs and symptoms in Sheehan's syndrome are caused by damage to the pituitary, thereby causing a decrease in one or more of the hormones it normally secretes. Since the pituitary controls many glands in the endocrine system, partial or complete loss of a variety of functions may result. [5]
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 ...
[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 ...
