The Monroe–Kellie doctrine states that the skull is a fixed and inelastic space and the accumulation of edema will compress vital brain tissue and blood vessels. [8] [38] Surgical treatment of cerebral edema in the context of cerebellar or cerebral infarction is typically done by removing part of the skull to allow expansion of the dura. [38]
High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.
The brain and kidneys work to achieve a fluid balance, which occurs when the amount of water consumed equals the amount of water excreted through urine, feces or sweat. ... but edema can occur in ...
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]
Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [1] Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1]
Of those who have residual symptoms after PRES, this is attributable largely to hemorrhage. [1] [4] Non-resolution of MRI abnormalities has been linked with poorer outcomes. [4] The presence of brain hemorrhage and cytotoxic edema (brain edema with concomittant brain tissue damage) is also associated with a poor prognosis. [2]
Lee's death was officially ruled the result of cerebral edema — swelling of the brain. While a normal human brain is about 3 pounds, Lee's was reportedly closer to 3½ pounds.
The best-studied medical treatment for intracranial hypertension is acetazolamide (Diamox), which acts by inhibiting the enzyme carbonic anhydrase, and it reduces CSF production by six to 57 percent. It can cause the symptoms of hypokalemia (low blood potassium levels), which include muscle weakness and tingling in the fingers. Acetazolamide ...
