Cerebral edema is commonly seen in a variety of brain injuries including ischemic stroke, subarachnoid hemorrhage, traumatic brain injury, subdural, epidural, or intracerebral hematoma, hydrocephalus, brain cancer, brain infections, low blood sodium levels, high altitude, and acute liver failure.
When fluid moves out of the intravascular compartment (the blood vessels), blood pressure can drop to dangerously low levels, endangering critical organs such as the brain, heart and kidneys; when it shifts out of the cells (the intracellular compartment), cellular processes slow down or cease from intracellular dehydration; when excessive ...
The cells in the brain may swell to the point where blood flow is interrupted resulting in cerebral edema. Swollen brain cells may also apply pressure to the brain stem causing central nervous system dysfunction. Both cerebral edema and interference with the central nervous system are dangerous and could result in seizures, brain damage, coma ...
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. ... suggest that human memory may be an even more complex affair than we have so far imagined. Non ...
(Neurons are the cells that send signals between your brain and the rest of your body.) Scientists used to think the cerebellum was specifically involved in coordinating movement and balance.
The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it.. In a study of mice, researchers at the Allen Institute identified ...
Using these techniques Nicholson showed that solute and water movement through the brain parenchyma slows as the extracellular volume fraction decreases and becomes more tortuous. [ 27 ] As an alternative explanation to diffusion, Cserr and colleagues proposed that convective bulk flow of interstitial fluid from the brain parenchyma to the CSF ...
In brain tissue, a biochemical cascade known as the ischemic cascade is triggered when the tissue becomes ischemic, potentially resulting in damage to and the death of brain cells. Medical professionals must take steps to maintain proper CBF in patients who have conditions like shock , stroke , cerebral edema , and traumatic brain injury .
