Cerebral edema is a major cause of brain damage and contributes significantly to the mortality of ischemic strokes and traumatic brain injuries. [ 4 ] [ 9 ] As cerebral edema is present with many common cerebral pathologies, the epidemiology of the disease is not easily defined. [ 1 ]
The diagnosis is usually made by a brain scan , in which areas of swelling can be identified. The treatment for PRES is supportive: removal of the cause or causes and treatment of any of the complications, such as anticonvulsants for seizures. PRES may be complicated by intracranial hemorrhage, but this is relatively rare. The majority of ...
The symptoms depend on the cause of the blockage, the person's age, and how much brain tissue has been damaged by the swelling. [11] In infants with hydrocephalus, CSF builds up in the central nervous system (CNS), causing the fontanelle (soft spot) to bulge and the head to be larger than expected. Early symptoms may also include: [11]
These factors cause the brain to swell with fluid, resulting in severe impairment. [15] If the swelling is untreated, it causes death by brain herniation. [4] The brain swelling is likely a result of vasogenic edema, the penetration of the blood–brain barrier by fluids. [16] This process has been observed in MRI studies.
Brain aneurysm causes: "Most aneurysms probably develop as a result of wear and tear on the arteries throughout a person's lifetime," the Brain Aneurysm Foundation noted . Some people can inherit ...
An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation, and restrict blood supply to the brain. [13] It is a cause of reflex bradycardia. [14]
[1] [2] Other causes include autoimmune diseases and certain medications. [2] In many cases the cause remains unknown. [2] Risk factors include a weak immune system. [2] Diagnosis is typically based on symptoms and supported by blood tests, medical imaging, and analysis of cerebrospinal fluid. [2] Certain types are preventable with vaccines. [5]
The symptoms vary greatly, in part, because of the underlying or causing infection. While the inflammation can cause a number of effects such as those mentioned previously, the base infection could cause other symptoms that don't necessarily have to do with the ventriculitis, itself. One of the challenges doctors face in diagnosing ...
