Cerebral contusion (Latin: contusio cerebri), a form of traumatic brain injury, is a bruise of the brain tissue. [2] Like bruises in other tissues, cerebral contusion can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion occurs in 20–30% of severe head injuries. [3]
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ventricles. [7] [10] [11] Diffuse axonal injury is a key pathology in concussive brain injury. [5] The visual system may be ...
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. [ 5 ]
cerebral contusion – a bruise to the brain tissue as a result of trauma. Contusions are local in nature, separating them from concussions. [5] diffuse axonal injury – These injuries are frequently seen in car accidents and cause permanent damage to the brain. Severe diffuse axonal injuries often lead to comas or vegetative states.
Glasgow Coma Scale (GCS) is the most widely used scoring system used to assess the level of severity of a brain injury. This method is based on objective observations of specific traits to determine the severity of a brain injury. It is based on three traits: eye-opening, verbal response, and motor response, which are gauged as described below.
A concussion, or traumatic brain injury, can affect how the brain works. Multiple concussions, like Tagovailoa has had, are more likely to do so, experts say. And he’s likely had more than three ...
In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. [1] Secondary brain injury occurs gradually and may involve an array of cellular processes. [1] [2] Secondary injury, which is not caused by mechanical damage, can result from the primary ...
