Cerebral edema is a potentially life-threatening complication of severely decreased sodium ion concentration in the blood (hyponatremia). [17] Ionic brain edema can also occur around the sites of brain hemorrhages, infarcts, or contusions due to a local plasma osmolality pressure gradient when compared to the high osmolality in the affected tissue.
An intraparenchymal bleed (bottom arrow) with surrounding edema (top arrow) Pediatric stroke is a stroke that occurs in children or adolescents. Stroke affects an estimated 2.5 to 13 per 100,000 children annually. [1] The signs and symptoms of stroke in children, infants, and newborns are different from those in adults.
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]
Hydrocephalus is a condition in which cerebrospinal fluid (CSF) builds up within the brain. [1] This typically causes increased pressure inside the skull.Older people may have headaches, double vision, poor balance, urinary incontinence, personality changes, or mental impairment.
[3] [27] The final step in treatment is to calculate the patients free water deficit, and to replace it at a steady rate using a combination of oral or IV fluids. [3] [27] The rate of replacement of fluids varies depending on how long the patient has been hypernatremic. Lowering the sodium level too quickly can cause cerebral edema. [27]
According to the over-regulation conception, brain vessels spasm in response to acute hypertension, which results in cerebral ischemia and cytotoxic edema. [14] [15] According to the autoregulation breakthrough conception, cerebral arterioles are forced to dilate, leading to vasogenic edema. [12] Cerebral edema can be generalized or focal ...

In the past, treatment options were limited to supportive medical therapy. [15] Currently, neonatal encephalopathy is treated using hypothermia therapy. [16] This has been shown to reduce brain damage, reduce future disability, and improve survival. [17] Hypothermia therapy is also sometimes termed hypothermic neural rescue therapy.
