The adolescent brain is 60 times more sensitive to components of the metabolic chain reaction that occurs after trauma, resulting in more diffuse cerebral swelling. [41] After the initial concussion, the children and young adults are more likely to sustain a second impact within the first two weeks.
Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury.It occurs when one set of muscles becomes incapacitated while the opposing set is not, and an external stimulus such as pain causes the working set of muscles to contract. [1]
Generally, brain injury is classified as: Severe, GCS ≤ 8; Moderate, GCS 9–12; Minor, GCS ≥ 13. [9] Tracheal intubation and severe facial/eye swelling or damage make it impossible to test the verbal and eye responses. In these circumstances, the score is given as 1 with a modifier attached (e.g. "E1c", where "c" = closed, or "V1t" where t ...
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.
[10] [11] Traumatic brain injury may cause a range of serious coincidental complications that include cardiac arrhythmias [117] and neurogenic pulmonary edema. [118] These conditions must be adequately treated and stabilised as part of the core care. Surgery can be performed on mass lesions or to eliminate objects that have penetrated the brain.
Traumatic brain injury may cause damage to the hypothalamus or the pituitary gland, and deficiencies of pituitary hormones (hypopituitarism) can cause similar symptoms to post-concussion syndrome; in these cases, symptoms can be treated by replacing any hormones that are deficient.

Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.
