The ultimate consequence of cytotoxic edema is the oncotic death of neurons. [1] The swelling of the individual cells of the brain is the main distinguishing characteristic of cytotoxic edema, as opposed to vasogenic edema, wherein the influx of fluid is typically seen in the interstitial space rather than within the cells themselves. [20]
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.
Symptoms vary depending on the location and the size of the area of involvement of the stroke. Edema, or swelling, of the brain may occur which increases intracranial pressure and may result in brain herniation. A stroke may result in coma or death if it involves key areas of the brain. [14]
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.
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
Stroke is the 5th-leading cause of death in the U.S. and a leading cause of severe disability. On average, a person dies from stroke every 4 minutes. He was given hours to live after stroke. 17 ...
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]
Nearly one in five new cervical cancers diagnosed from 2009 to 2018 were in women 65 and older, according to a new UC Davis study.But what has experts concerned is that, according to the study ...
