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.
The sudden collapse seen in patients may be due to a type of cerebral edema that can follow an initial impact in children and teenagers, rather than to SIS. [45] This type of edema, referred to as diffuse cerebral swelling , may be the real reason for the collapse which young people sometimes experience and which is commonly thought to be due ...
Brain injury can occur at the site of impact, but can also be at the opposite side of the skull due to a contrecoup effect (the impact to the head can cause the brain to move within the skull, causing the brain to impact the interior of the skull opposite the head-impact). While impact on the brain at the same site of injury to the skull is the ...
Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people. [ 1 ] [ 2 ] Overall, closed-head injuries and other forms of mild traumatic brain injury account for about 75% of the estimated 1.7 million brain injuries that occur ...
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]
TBI is a leading cause of death and disability around the globe [8] and presents a major worldwide social, economic, and health problem. [10] It is the number one cause of coma, [169] it plays the leading role in disability due to trauma, [76] and is the leading cause of brain damage in children and young adults. [15]
If your sodium levels get too low (below 135 milliequivalents per liter), extra water may enter your cells and cause swelling. That can lead to symptoms such as confusion, convulsions, headache ...
Damage to the Broca's area and the Wernicke's area of the brain (left side) typically causes problems with speech and language. Damage to the right side of the brain may interfere with the ability to express emotions or interpret what one sees. Damage on either side can cause paralysis of the opposite side of the body.
