Brain Injury

All You Need to Know About a Brain Injury

TBI is a disruption in the brain’s normal function caused by a blow, bump, or jolt to the head, the head striking an object suddenly and violently, or when an object pierces the skull and enters brain tissue. There are various traumatic brain injury causes as it can be caused due to any factor. Observing any of the following clinical signs indicates a change in normal brain function

  • Consciousness loss or reduction
  • Memory loss for events that occurred prior to or following the event (amnesia)
  • Muscle weakness, loss of vision, and changes in speech are examples of focal neurological disorders.
  • Disorientation, slow thinking, or difficulty concentrating are examples of mental state changes and increased blood pressure and stress levels

Head injury symptoms might include:

  • Severe fatigue
  • Vomiting
  • Headache 
  • The confused state of mind 
  • Paralysis
  • Coma
  • Consciousness loss
  • Pupils dilated
  • Breathing difficulties
  • Vision shifts (blurred vision or seeing double, unable to tolerate bright light, loss of eye movement, blindness)
  • CSF (cerebrospinal fluid) (clear or blood-tinged) emerges from the ears or nose
  • Concerns about dizziness and balance
  • Slow heartbeat
  • Slow breathing rate accompanied by an increase in blood pressure
  • Hearing loss or ringing in the ears
  • Difficulties with cognition
  • Emotional reactions that are inappropriate
  • Difficulties with speech (slurred speech, inability to understand and articulate words)
  • Swallowing Difficulties
  • Numbness or tingling throughout the body
  • Eyelid drooping or facial weakness
  • A loss of bowel or bladder control and bladder pain

The warning signs may be different in each person depending on the severity and location of the injury.

TBIs can result in “mass lesions,” which are areas of localized injury like hematomas and contusions that increase pressure within the brain. The following are some examples of types of traumatic brain injuries:


A blood clot that forms within the brain or on its surface is referred to as a hematoma. Hematomas can form anywhere in the brain. An epidural hematoma is a collection of blood that forms between the dura mater (the brain’s protective covering) and the inside of the skull. A subdural hematoma is a collection of blood between the dura mater and the arachnoid layer on the brain’s surface.


A cerebral contusion is brain tissue bruising. Under a microscope, cerebral contusions look similar to bruises in other parts of the body. They are made up of damaged or swollen brain tissue mixed with blood that has leaked from arteries, veins, or capillaries. Contusions are most commonly found at the base of the frontal lobes, but they can occur anywhere.

Intracerebral Hemorrhage:

An intracerebral hemorrhage (ICH) is defined as bleeding within the brain tissue and may be associated with other brain injuries, particularly contusions. The size and location of the hemorrhage influence whether it can be surgically removed.

Subarachnoid Hemorrhage: 

Subarachnoid hemorrhage is caused by bleeding into the subarachnoid space (SAH). It manifests as diffuse blood spread thinly across the surface of the brain and is most common after a TBI. The majority of SAH cases associated with head trauma are minor. Severe traumatic SAH can cause hydrocephalus.

Diffuse injuries:

TBIs can cause microscopic changes in the brain that do not show up on CT scans and are distributed throughout the brain. This type of injury, known as diffuse brain injury, can occur with or without a mass lesion.

In any brain traumatic injury, there are several traumatic brain injury recovery stages that can involve in the recovery process. 

Here are the major aspects that are involved in the diagnosis of brain injury:

Anyone who exhibits moderate to severe TBI symptoms should seek medical attention as soon as possible. Because there is little we can do to reverse the initial brain damage caused by trauma, medical providers attempt to stabilize a person with TBI and focus on preventing further injury.

Radiology tests:

CT or CAT scans are the gold standards for TBI radiological assessment. A CT scan is easy to perform and can detect blood and fractures, two crucial lesions in medical trauma cases. Some recommend plain skull x-rays for mild neurological dysfunction. CT scanning is readily available in most centers, making skull x-rays for TBI patients less common.

Various options are available for the traumatic brain injury treatment:


Many patients with moderate to severe head injuries go straight from the ER to the operating room. In many cases, surgery is performed to remove a large hematoma or contusion that compresses or raises the skull’s pressure. These patients are being monitored in the intensive care unit following surgery (ICU).

Other patients with head injuries may not be taken to the operating room right away but instead are transferred from the emergency room to the ICU. Because contusions or hematomas can enlarge in the hours or days following a head injury, immediate surgery is not recommended for these patients until several days have passed.

Immediate medical assistance is required to ensure the damage is not further complicated. A severe traumatic brain injury can take a long time to recover from. Some people regain consciousness and recover quickly within a few days or weeks. Others progress more slowly, and it may take about a few months or even a year. Every injury is unique and has its timetable.
