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 ...
Hypothalamic dysfunction refers to the hypothalamus, which is a structure within the brain which participates in regulating the pituitary gland, autonomic nervous system, and endocrine system. [6] Symptoms related to hypothalamic dysfunction may include abnormal sodium balance ( hyponatremia or hypernatremia ), high progestin levels, low ...
Hypothalamic disorders result from a deficiency in the release of gonadotropic releasing hormone , while pituitary gland disorders are due to a deficiency in the release of gonadotropins from the anterior pituitary. [1] GnRH is the central regulator in reproductive function and sexual development via the HPG axis.
One of the most troublesome hamartomas occurs on the hypothalamus. Unlike most such growths, a hypothalamic hamartoma is symptomatic; it most often causes gelastic seizures, and can cause visual problems, other seizures, rage disorders associated with hypothalamic diseases, and early onset of puberty. The symptoms typically begin in early ...
The hypothalamus is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...

Hypogonadism resulting from hypothalamic or pituitary defects is termed hypogonadotropic hypogonadism (HH), secondary hypogonadism, or central hypogonadism (referring to the central nervous system). [3] Examples of hypothalamic defects include Kallmann syndrome. Examples of pituitary defects include hypopituitarism and pituitary hypoplasia.
This benign tumor may not cause any medical problems; however, some hypothalamic hamartomas lead to seizures or hormone abnormalities. Other features of Pallister–Hall syndrome include a split opening of the airway called bifid epiglottis, laryngeal cleft, blockage of the anal opening (imperforate anus), and kidney abnormalities. Signs and ...
