Drug-induced comas are used to protect the brain during major neurosurgery, as a last line of treatment in certain cases of status epilepticus that have not responded to other treatments, [2] and in refractory intracranial hypertension following traumatic brain injury. [1] Induced coma usually results in significant systemic adverse effects.
The duration of PTA in brain-injured patients is a useful predictor of the expected long-term effects of the injury, [36] along with the duration of loss of consciousness(LOC), and scores on the Glasgow Coma Scale (GCS), which measures degrees of consciousness, with higher scores indicating higher levels of functioning. A score of three ...
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.

Tereza Nová, an Olympic alpine skier, is in a medically induced coma. The Czech athlete, 26, was hospitalized with a serious head injury after experiencing a fall while training in Garmisch ...
Traumatic encephalopathy syndrome, dementia pugilistica, [1] punch drunk syndrome: A normal brain (left) and one with advanced CTE (right) Specialty: Neurology, psychiatry, sports medicine: Symptoms: Behavioral problems, mood problems, problems with thinking [1] Complications: Brain damage, dementia, [2] aggression, depression, suicide [3 ...
Imaging encompasses computed tomography (CAT or CT) scan of the brain, or MRI for example, and is performed to identify specific causes of the coma, such as hemorrhage in the brain or herniation of the brain structures. [35] Special tests such as an EEG can also show a lot about the activity level of the cortex such as semantic processing, [36 ...
The Glasgow Coma Scale is commonly used to assess the severity of traumatic brain injuries, including closed-head injuries. The scale tests a patient's eye, verbal, and motor responses. The scale goes up to fifteen points; with fifteen being the most mild injury, less than eight being a severe brain injury, and three being a vegetative state. [12]
While impact on the brain at the same site of injury to the skull is the coup effect. If the impact causes the head to move, the injury may be worsened, because the brain may ricochet inside the skull causing additional impacts, or the brain may stay relatively still (due to inertia) but be hit by the moving skull (both are contrecoup injuries).
