<unk>  is frequently encountered in acute brain injuries from a variety of origins, including but not limited to: * Traumatic brain injury * Stroke * Tumors * Infections (such as a brain abscess or meningitis) * Hepatic encephalopathy * Posterior reversible encephalopathy syndrome * Radiation-induced brain<unk>  * Post-surgical changes * Amyloid-related imaging abnormalities associated with<unk>  (ARIA-E) * Hyponatremia * High-altitude<unk>  Risk factors<unk>  is present with many common<unk> rebral pathologies and risk factors for development of<unk>  will depend on the cause. The following were reliable predictors for development of early<unk>  in ischemic strokes. * Younger age * Higher severity of symptoms on the National Institutes of Health Stroke Scale * Signs of current ischemia on clinical exam * Decreased level of consciousness * Hyper dense artery sign and larger affected area on CT imaging * Higher blood glucose
Cerebral edema
Brain herniation
Brain ischemia
Encephalitis
