  • Hypoxia
  • High altitude cerebral edema (HACE) is a severe and sometimes fatal form of altitude sickness that results from capillary fluid leakage due to the effects of hypoxia on the mitochondria -rich endothelial cells of the blood-brain barrier. (wikipedia.org)
  • injury
  • USMLE has also focused recent efforts on the often unrecognized health care needs of recently returning servicemen and servicewomen (eg, traumatic brain injury and post-traumatic stress disorder), and the families of deployed servicemen and servicewomen. (docplayer.net)
  • palsy
  • Clinical presentation correlates with the severity of associated supratentorial anomalies, varying from mild truncal ataxia and normal intelligence to cerebral palsy. (blogspot.com)
  • Cranial
  • Certain changes in morphology are associated with cerebral edema: the brain becomes soft and smooth and overfills the cranial vault , gyri (ridges) become flattened, sulci (grooves) become narrowed, and ventricular cavities become compressed. (wikipedia.org)
  • capillaries
  • The brain then recruits capillaries to become veins and these in turn are also damaged leading to further iron deposition. (ms-mri.com)
  • It is thought to result from direct transmission of pressure to cerebral capillaries with transudation of fluid from the capillaries into the extravascular compartment . (wikipedia.org)
  • findings
  • Other common supratentorial findings include fused thalami, fornices and cerebral peduncles, absence of the septum pellucidum, dysgenesis of the limbic system, cortical malformations and multiple suture synostoses. (blogspot.com)
  • stroke
  • During an ischemic stroke , a lack of oxygen and glucose leads to a breakdown of the sodium-calcium pumps on brain cell membranes, which in turn results in a massive buildup of sodium and calcium intracellularly. (wikipedia.org)
  • While not all patients who have experienced a stroke will develop a severe edema, those who do have a very poor prognosis. (wikipedia.org)
  • metabolism
  • Altered metabolism may cause brain cells to retain water , and dilution of the blood plasma may cause excess water to move into brain cells. (wikipedia.org)
  • white matter
  • In vasogenic and interstitial edema, electron microscopy has shown an increase of interstitial spaces in white matter amounting to 1000 nm, versus 60 nm in normal white matter .These enlarged extracellular spaces, with free water, may be the dominant source for the total brain water signal, resulting in increased ADC. (mussenhealth.us)
  • These images are more sensitive than conventional MRI to determine the extent of edema in both gray and white matter. (mussenhealth.us)
  • 1993) Discrimination between different types of white matter edema with diffusion-weighted MR imaging. (mussenhealth.us)
  • left
  • The longitudinal fissure runs from the brow to the back of the head, and deep within it is a bed of matted white fibers, the corpus callosum , which connects the left and right cerebral hemispheres . (thefreedictionary.com)
  • management
  • Definitive management of encephalitis can be highly organism specific, yet for many of the infectious etiologies the lack of effective antimicrobial therapy necessitates a general approach and patience in the face of an uncertain prognosis. (neurologyadvisor.com)
  • cases
  • Could this hemosiderin correspond for example to those cases where we see iron deposition with SWI in lesions in the brain (14)? (ms-mri.com)
  • motor
  • In the sensory strip are the brain cells that register all sensations, and in the motor strip are the nerves that control the voluntary muscles. (thefreedictionary.com)
