How to deal with Traumatic Brain Injury
Head injury, known by the medical term Traumatic Brain Injury or TBI, is one of the leading causes of death and disability worldwide.
Causes
While the causes of TBI can be unique on a case-to-case basis, they can all be classified under motor vehicle accidents as a driver or passenger; motor vehicle accidents as a pedestrian; falls from low or high heights; wilful assault leading to head injury; sporting or recreational injuries; domestic violence and child abuse.
When trauma occurs as described above, one of the two possibilities arises: A bruise develops directly at the site of the injury, which is called a coup lesion. Another chance is that the head is jolted back violently, causing the brain to knock on the back of the skull, causing a bruise there, which is called a countercoup lesion. In both cases, the outer lining of the brain, as well as some tissues inside, may get damaged, or some blood vessels may rupture, causing bleeding. In some cases, the brain may swell up, creating intense pressure on the brain from intra-cranial fluid, a condition called raised intracranial pressure.

Types of TBI
- Skull fracture: a fracture or break in one or more areas of the skull
- Epidural hematoma: blood from a ruptured blood vessel fills up in the space between the head and dura, causing pressure on the brain
- Acute subdural hematoma: Here, the blood collects in the space between the dura and the surface of the brain
- Chronic subdural hematoma: Here, the subdural hematoma happens gradually and in multiple episodes
- Intraparenchymal hemorrhages: Bleeding inside the brain
- Contusion: bruises caused by the brain knocking inside the skull

Diagnosis

- Blood tests
- X-rays
- Computed tomography or CT scan
- Magnetic resonance imaging or MRI scan
- Electroencephalogram or EEG
Treatment & Rehabilitation
Treatment options depend on various parameters such as age, state of health, immune status, medical history of the patient, extent and type of head injury, expected course of the impact of the injury, complications and the patient’s response to specific medications, procedures or therapies.
Depending on whether it is a mild or severe head injury, the doctor may resort to one or more of these:
- If there is just a bump or no wound on the head, the doctor may apply an ice-pack and advise complete rest.
- If there is a wound on the head, he/she will apply a topical antibiotic ointment and adhesive bandage, along with stitches to close the wound.
- Depending on how the patient is feeling, the doctor may prescribe pain relief or sedation
- Patients may need assisted breathing using a breathing machine, mechanical ventilator or respirator.
- All the above would be followed by hospitalization for a few days to observe the patient and provide immediate medical attention if required.
- If the response to these measures are unsatisfactory and the injury is severe, he/she may require emergency surgery.
