Traumatic Brain Injury (TBIs) are never something to brush off. The effects can range from mild confusion to lifelong disabilities or worse. Understanding TBIs is incredibly important, not just for people in high-risk jobs or athletes, but for everyone. A traumatic brain injury can happen to anyone, anywhere, on the road, at work, or even at home.
And in most cases, it doesn’t look as dramatic on the outside as it feels on the inside. That’s why many TBIs go unnoticed or untreated until they become serious problems. Even something as common as a concussion can lead to long-term effects if it’s not taken seriously right away. You will need to hire a lawyer to handle the legal complications in TBI claims, especially when the liability is disputed. You have to know what a traumatic brain injury is and how they impact the body, which is the first step in protecting yourself and the people around you.
What Exactly Is a Traumatic Brain Injury?
A traumatic brain injury happens when the brain is damaged by an external force. This could be a hard blow to the head or body, or even something piercing the skull, like a piece of shrapnel or a bullet.
TBIs are divided into two main types: penetrating and non-penetrating.
Penetrating TBI (also called open TBI) is when an object actually enters the skull and goes into the brain tissue. These usually damage only one part of the brain. Non-penetrating TBI (also called closed TBI) is caused by something strong enough to shake the brain inside the skull, like a fall or a car crash. Sometimes, people suffer from both types at once.
The effects of a traumatic brain injury aren’t always immediate. Some injuries are primary and happen at the moment of impact. Others are secondary and develop slowly over hours or even days as the brain swells, bleeds, or reacts to the initial injury.
Signs That a TBI Might Be Happening
Some physical symptoms include:
- Headaches
- Dizziness
- Confusion
- Slurred speech
- Seizures
- Vomiting
- Unequal pupil sizes
- Weakness in the arms or legs after a head injury
Other signs include changes in sleep patterns, memory problems, sensitivity to light or sound, and trouble focusing. Even if the symptoms seem mild at first, they can worsen quickly.
For children, it’s even trickier. Kids might not be able to explain what’s wrong. So, adults need to watch for sudden crying, loss of balance, changes in sleep or eating habits, and odd behavior. A child losing skills they already had, like toilet training, is another sign that something serious might be happening.
How TBI Affects the Brain on the Inside
Damage from a traumatic brain injury can either affect a specific area (called a focal injury) or the whole brain (called a diffuse injury). When the brain is damaged, it can swell, bleed, or even tear the nerve fibers that send signals throughout the body.
One serious type of damage is called diffuse axonal injury (DAI), which means widespread tearing of nerve fibers. This usually happens during car crashes or falls and can seriously mess with how different parts of the brain talk to each other. DAI may even release harmful chemicals that make the damage worse over time.
Then there’s the concussion, a mild but still serious traumatic brain injury. A concussion might not always knock someone out, but it can cause confusion, dizziness, and even memory loss.
While some people recover in minutes or hours, others deal with symptoms for weeks or longer. And if someone suffers a second concussion before the first one heals, the result can be permanent brain damage or even death.
Long-Term Problems and Lasting Effects of a TBI
Some brain injuries don’t just stop at the moment of impact; they keep causing problems for years.
Chronic traumatic encephalopathy (CTE) is one of the most serious conditions linked to repeated head trauma. It’s been found in boxers, footballers, and others who take repeated hits to the head.
CTE can lead to memory loss, trouble thinking clearly, depression, and even dementia, but the symptoms might not appear for many years.
There’s also post-traumatic dementia (PTD), which can happen after just one severe traumatic brain injury. People who experience a serious traumatic brain injury in their younger years might face a higher risk of developing dementia as they grow older.
The brain is too important to take chances with, so if there’s any doubt at all, get it checked out, take it seriously, and don’t wait.
