The brain is a remarkably resilient part of the human body, and at the same time, is equally vulnerable. A sudden shock from a fall, road accident, or collision can result in severe disruption in the delicate balance of the brain. What makes it daunting is that these impacts usually do not start to show signs immediately. They develop silently, affecting the core power of the brain. This is what we call traumatic brain injury.
But in today’s time, when medical science has developed beyond imagination, traumatic brain injuries can be treated and managed better. The first step is to learn about TBI, its causes, symptoms, treatment and more.
What is a Traumatic Brain Injury?
As the name itself suggests, a traumatic brain injury occurs when the brain is damaged due to a sudden external force, like a fall, bump, violent shaking, jolt, etc. An injury like this can have varying impacts depending on the severity of the shock the brain has received. Traumatic brain injury can have a wide spectrum of presentation. In some cases, it can lead to only concussions; in others, it can result in unconsciousness, brain bleeding, or even coma.
Traumatic Brain Injury: What Happens to the Brain?
When an individual has gone through a traumatic brain injury, the impacts are varying: sometimes mild, sometimes abrupt and severe. Let’s understand what commonly happens to the brain after a traumatic brain injury:
- Immediate Effects
Usually, the immediate effects of sustaining a traumatic brain injury include bruising of the brain tissue, tearing of nerve fibres, bleeding, or swelling within the skull. Now, since the skull is a confined space, even a mild swelling can be harmful.
- Chemical Changes
When an individual has sustained a traumatic brain injury, their brain starts to release inflammatory chemicals and neurotransmitters that often worsen the damage to the surrounding brain cells.
- Secondary Injury
Secondary injury is often referred to as the impact that is observed within a few hours or a few days of sustaining a traumatic brain injury. In many cases, reduced blood flow, increasing swelling within the skull, and a lack of oxygen that can lead to brain cell death have been observed. In even more severe cases, the swelling can cause some parts of the brain to shift or become compressed, which can be life-threatening.
Since the impact of sustaining a traumatic brain injury is severe and life-threatening in some cases, it is best advised to seek immediate medical attention.
Understanding the Signs and Symptoms of Traumatic Brain Injury
Identifying warning signs, science, and symptoms of traumatic brain injury is not always very simple. This is because symptoms may not always be dramatic or visible. However, recognising them at an early stage can be life-saving.
Let’s take a look at some warnings, science, and symptoms of TBI:
Physical Symptoms
- Persistent headache
- Nausea or vomiting
- Dizziness
- Vision disturbances
- Loss of balance or coordination
Cognitive Symptoms
- Difficulty concentrating
- Forgetfulness
- Slowed thinking or confusion
Behavioural and Emotional Changes
- Mood swings
- Irritability
- Anxiety or depression
Sleep Disturbances
- Sleeping more than usual
- Difficulty sleeping
- Constant grogginess or fatigue
The Seriousness of Traumatic Brain Injury: Mild, Moderate and Severe
Traumatic brain injury is not the same across all cases. It varies depending on several factors, such as the severity of the impact, age, gender, etc.
Let’s understand the seriousness of TBI on three spectrums:
- Mild TBI
In cases of mild TBI, individuals often face concussion, headache, and a foggy feeling, lack of consciousness for a short period, or no loss of consciousness at all.
- Moderate TBI
In cases of moderate TBI, individuals can face longer periods of unconsciousness and deficits in physical, motor, and cognitive abilities.
- Severe TBI
Severe TBI can be life-threatening as it might include prolonged brain swelling or bleeding that is often visible through imaging, severe cognitive impairment, etc.
Remember that these spectrums often overlap with each other. Even a mild TBI can become severe if not managed properly.
Traumatic Brain Injury Diagnosis: What is the Procedure?
Since the impact of a traumatic brain injury or even its symptoms is not straightforward, your surgeon relies on a combination of methods to perform the diagnosis. Here’s how TBI is usually diagnosed:
- Neurological Examinations
Neurological examinations are performed to assess muscle strength, coordination, memory, reflexes, etc.
- Imaging Tests
Imaging tests usually include performing CT scans or MRIs. These tests help identify swelling, bleeding, or skull fractures.
- Observation and Cognitive Testing
In case of a traumatic brain injury, observation and cognitive testing are considered essential to identify symptoms of initial or mild TBIs.
What is the Treatment and Recovery Process?
A traumatic brain injury is extremely complex, and therefore, the treatment requires an initial diagnosis assessment first. The treatment and care depend on the severity and an individual’s symptoms.
To give you an idea, here’s what the treatment and recovery process looks like:
- Mild TBI
When a mild TBI has been diagnosed, the surgeon might suggest physical and mental rest. For the next few days, close monitoring of symptoms is performed, and gradually the patient is allowed to return to daily activities.
- Moderate to Severe TBI
In cases of moderate to severe TBI, the treatment can include hospitalisation, medications, or even surgery to remove a blood clot or relieve pressure inside the skull.
- Rehabilitation
Even after a successful treatment or surgery, rehabilitation is crucial for TBI. TBI rehabilitation can include physiotherapy, speech therapy, mental health counselling, and occupational therapy.
Always remember that a traumatic brain injury is not just about physical healing, but also emotional and cognitive recovery. The process and duration of recovery vary from one individual to another.
Is Traumatic Brain Injury Preventable?
Chromatic brain injuries occur due to an external force, like a collision or shock. Therefore, the prevention methods usually revolve around simple safety measures such as:
- Following traffic rules while driving, such as wearing a helmet and a seatbelt. Avoid alcohol consumption before driving.
- Abiding by safety rules while playing sports.
- Creating a safe home, especially when children or older people are around. This includes proper lighting, railing, and nonslip surfaces.
- Spreading awareness and education about head injuries and the role of initial diagnosis and treatment.
Life After TBI: Focus on Adjusting and Moving Forward
Dealing with a brain injury can be a traumatic experience. Since the recovery outcomes vary from one individual to another, the goal should be to focus on adjusting the lifestyle accordingly and moving forward.
With the right support system of family, friends, healthcare professionals, therapists, and community resources, individuals who have experienced a traumatic brain injury can rebuild confidence, purpose, and independence.
