Lateral medullary syndrome and lateral pontine syndrome mnemonic. A constellation of signs and symptoms associated with a lesion in both sides of the ventromedial hypothalamus, especially hyperphagia, bulimia (1), and aggression or rage. When research into the lateral hypothalamus began, the Lateral hypothalamic syndrome: its modification by obesity and leanness. Disturbance of body weight Hypothalamic obesity : Lesion in Ventromedial hypothalamus Paraventricular nucleus Effect- Uncontrolled voracious appetite causing the pt extreme obesity. Question Is lateral hypothalamic deep brain stimulation (DBS) safe for the treatment of obesity in Prader-Willi syndrome?. Hypothalamic Disorders: Pathophysiologic Principles Lateral pontine syndrome closely resembles lateral medullary syndrome the only difference is location of occurrence. Signs and symptoms include: Anorexia Aphagia Adipsia See also Adiposogenital dystrophy Ventromedial hypothalamic syndrome See also References Coleman,A F (2006). 1980 Jun 9;26(23):1927-34. Damage to this area can cause reduced food intake and lateral hypothalamic syndrome. The hypothalamospinal tract arise mainly from the paraventricular nucleus, lateral and posterior hypothalamic areas. They show that the capacity to build and sleep in a nest promotes sleep initiation and consolidation and that pre-sleep nesting is controlled by non-hypocretin glutamatergic LH ensembles that also gate sleep initiation and intensity. The T-NSB and LH lesions produced equivalent decreases in caudate and telencephalic contents of dopamine and norepinephrine, while with the exception of telencephalic dopamine .

Investigated the role of the vagus in the lateral hypothalamic (LH) syndrome to body weight loss in 80 male Sprague-Dawley albino rats. (A) Power spectrum of hypothalamic activity measured at baseline. In the state of hypophagia a preference for wet and sweet food was observed, whereas a marked aversion for raw meat occurred. . The . The syndrome consists of two phases. The first phase is marked by hyperphagia and subsequent weight gain, causing obesity.The second phase is inclusive of steadying of body weight, resistance to food-getting behavior, and fickle or picky behavior. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of the pons. 13 (3) 345-347, 1974.

Anxiety disorders affecting millions of people are a global health problem, where new therapies and targets are much needed. Further observations indicate that lesioned Ss reduce their level of regulated body weight to some fixed percentage of control values. - Lesions of the lateral hypothalamus in female rats made experimentally obese or lean were followed by a lengthening or shortening of the aphagic period.

Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. In this article, we will show that lateral hypothalamic lesions produce a complex set of symptoms--a syndrome of deficits in drinking as well as in feeding behavior from which the animals recover at different rates.

The long tracts involved will be the same as in lateral medullary syndrome, the spinothalamic tract and the descending hypothalamic fibers.

Recent work has forced revisions in traditional concepts regarding the role of the hypothalamus in the control of feeding. The importance of this function is underscored by the structural organization and connectivity of the hypothalamus as almost every major subdivision of the neuraxis communicates with the hypothalamus and is subject to its influence. Lateral habenular nucleus The lateral habenular nucleus receives fibers from the frontal cortex, the septal nuclei (limbic system), the lateral preoptic area, and the lateral hypothalamus as well as the ventral tegmental area.

The hypothalamus is a small organ, which lies deep within the centre of the brain. the lateral hypothalamus ( lh ), also called the lateral hypothalamic area ( lha ), contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain Imaging advances allow for early, even prenatal, detection.
