How long does brain swelling usually last?

How long is too long for swelling on the brain?

• Answer:

  On One Hand: Minutes of Severe Swelling Can Cause DeathBrain swelling, or cerebral edema, usually results from an illness or head injury. Fluid accumulates within the brain tissue, and because the brain is housed within the skull, there is no room for expansion. Intercranial pressure (ICP) increases, eventually causing death if left untreated. A few minutes of uncontrolled ICP can result in permanent damage to brain tissue and lead to death.On the Other: The Brain's Recovery PotentialIf the brain has suffered extensive damage due to swelling, that damage is likely permanent. As far as is known now, damaged brain tissue does not regenerate. However, depending on how widespread the brain injury is, other portions of the brain can adapt and take over the damaged portions' functions. Depending on other health factors, a patient who experienced significant brain swelling could recover somewhat.Bottom LineSwelling must be monitored and controlled as soon as possible after onset. If brain swelling is monitored and treated, potential damage can be limited. According to the Mayo Clinic, acute emergency care is concerned primarily with "preventing the brain damage from getting any worse" by controlling brain swelling as part of the initial treatment.Source:http://www.neurologychannel.com/tbi/treatment.shtmlhttp://www.neurologychannel.com/tbi/prognosis.shtmlhttp://hosting.texoma.net/business/biotech/thia-faq.htmhttp://www.mayoclinic.com/health/traumatic-brain-injury/DS00552/DSECTION=treatments-and-drugsOn One Hand: On the Other: Bottom Line
