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 ...
Traumatic brain injury may cause damage to the hypothalamus or the pituitary gland, and deficiencies of pituitary hormones (hypopituitarism) can cause similar symptoms to post-concussion syndrome; in these cases, symptoms can be treated by replacing any hormones that are deficient.
The symptoms depend on what part of the pituitary is affected. Lymphocytic adenohypophysitis (LAH) occurs when the anterior pituitary cells are affected by autoimmune inflammation resulting in either no symptoms, adrenal insufficiency (if the ACTH producing cells are affected), hypothyroidism (if the TSH producing cells are damaged), or ...
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 hypothalamus produces and releases gonadotropin-releasing hormone (GnRH). GnRH nudges the pituitary gland to produce luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
The cardinal symptoms of Parkinson's disease: tremor, bradykinesia, and rigidity are initially responsible for swallowing, which is mainly observed in the advanced stages of the disease; Damage to the lateral hypothalamus can also lead to aphagia, as seen in the 1978 study by Timothy Schallert and Ian Whishaw.

The hypothalamus region of the brain regulates basic functions of hormone release, emotional expression and sleep. One study concluded that the neurochemical hypocretin, also known as orexin, which is regulated by the hypothalamus, was significantly reduced in study participants with symptoms of cataplexy. Hypocretin regulates sleep and states ...
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with body temperature exceeding the normal range due to an increase in the body's temperature set point in the hypothalamus.
