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]
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.
Certain drugs (for example, amlodipine) can cause pedal edema. Cerebral edema is extracellular fluid accumulation in the brain. [1] It can occur in toxic or abnormal metabolic states and conditions such as systemic lupus or reduced oxygen at high altitudes. It causes drowsiness or loss of consciousness, leading to brain herniation and death.
Psychogenic polydipsia caused by psychiatric disorders—oftentimes schizophrenia—is frequently accompanied by the sensation of dry mouth. Some conditions with polydipsia as a symptom are non-psychogenic (e.g., early Type 2 diabetes , primary hyperaldosteronism , and zinc deficiency , and some forms of diabetes insipidus ).
The physiological cause of altitude-induced edema is not conclusively established. It is currently believed, however, that HACE is caused by local vasodilation of cerebral blood vessels in response to hypoxia, resulting in greater blood flow and, consequently, greater capillary pressures. On the other hand, HAPE may be due to general ...
The cause of death: cerebral edema, a swelling of the brain brought on after Lee had taken too much aspirin." It also mentioned that toward the end of his life, Lee had suffered "several public ...
[9] [3] In some cases, people will develop concomitant neurological features such as poor coordination, altered consciousness, or cerebral edema (High-altitude cerebral edema). [9] [3] On physical exam, increased breathing rates, increased heart rates, and a low-grade fever 38.5 o C (101.3 o F) are common.
Researchers challenge Bruce Lee's cause of death, positing that his brain swelling was caused by low sodium due to chronic elevated water intake. Kidney specialists float a new theory after ...
