What Are the Different Types of Brain Injuries That Exist Today?

Did you know that almost 6 million people suffer from traumatic brain injuries every year? Unfortunately, some injuries go unnoticed without any brain injury diagnosis.

If you want to support your healthy brain, you need to know about different kinds of injuries. Understanding early warning signs can help protect your health and well-being.

The following guide will explore several common types of brain injuries and what to look for. Read on to help ensure optimal health for your brain before it’s too late.

Traumatic Brain Injuries

Traumatic brain injuries involve injuries to the brain induced by an impact on the head. Examples of causes include car crashes, physical assaults, slips and falls, and workplace accidents.

The consequences of a TBI depend on a lot of different factors such as the specific kind, location, and severity. If you’ve suffered a traumatic brain injury, make sure to get plenty of rest and avoid physical activity until cleared by a doctor.

Second Impact Syndrome

Second impact syndrome involves a situation where a person encounters a second head injury before they fully heal from the first head injury. It’s a common injury for athletes that suffer from post-concussive symptoms after injuring their head.

SIS can cause diffuse cerebral swelling and severe brain herniation, and might even result in death. If you’ve recently had a head injury, learn more about 2nd impact syndrome and consider the risks.


Concussions cause the brain to bounce around inside the skull resulting in mild damage. Examples of common concussion causes include falls, car crashes, physical assaults, and sports injuries.

Fortunately, most mild head injuries don’t lead to long-term brain damage. However, they can cause temporary brain function issues that go on for several weeks.

A concussion might include losing consciousness for less than half an hour. They can also lead to post-traumatic amnesia for less than a day after the injury.

Concussion symptoms often include confusion, strange behavior, and memory loss. Keep in mind that only 1 out of 10 concussions result in losing consciousness.


A stroke is a medical emergency that also goes by the name of a “brain attack”. They can result from an artery getting ruptured or blocked.

In other cases, blood flow might not reach a part of the brain if a blood vessel bursts in the brain. With a stroke, the brain becomes damaged, or might even stop functioning.

Stroke symptoms include abrupt numbness or loss of strength in the arm, leg, or face. Symptoms tend to occur only on a single side of the body.

You should also watch for sudden confusion, difficulty speaking, or problems comprehending speech. Some strokes result in issues seeing in a single eye or both eyes. They often cause walking issues, dizziness, balance problems, and less coordination.

Brain Aneurysm

A brain aneurysm, or cerebral aneurysm, involves swelling in a vulnerable region of an artery in or near the brain. The continuous blood flow pressure forces the vulnerable artery region outward and creates a bump like a blister.

The aneurysm extends even more when blood flows into the swollen area. Think about how a balloon becomes thinner as it fills with more air and gets closer to popping.

It’s important to note that brain aneurysms can happen anywhere in your brain. However, most aneurysms occur in the major arteries sitting at the bottom of the skull.

Sometimes, people who experience a brain aneurysm have more than one aneurysm. Most brain aneurysms tend to be small and don’t provoke any identifiable symptoms.

One way an aneurysm can cause symptoms is if it puts stress on brain tissue or nerves. If it bursts or leaks out, it induces dangerous bleeding in the brain.

A burst brain aneurysm might lead to death and always requires immediate medical treatment. The longer you wait to treat a burst aneurysm, the more life-threatening it becomes and the chance of disability also increases.

Brain Hemorrhages

Sometimes it only takes a minor head injury to cause a brain hemorrhage. Symptoms can show up immediately or they might take several weeks to evolve. Once a brain bleed gets identified, they require immediate medical attention.

Subdural and extradural hemorrhages are common types of brain bleeding that can cause added brain damage and long-term effects.

Subarachnoid and intracerebral hemorrhages are the other two main types and they tend to occur randomly. They involve tiny blood vessels bursting and often cause the sufferer to lose consciousness.

Symptoms of a hemorrhage include intense headaches, loss of strength, numb legs and arms, and nausea. Sometimes sufferers experience vision changes, balance changes, and trouble talking or comprehending speech.

In some cases, hemorrhages can affect the fine motor skills of an individual or cause them to have seizures.


Encephalitis involves the brain becoming inflamed and several things can cause this to happen. Examples include viral infections, autoimmune inflammation, bacterial infections, and bites from different bugs.

If an infection causes inflammation in the brain, it’s referred to as infectious encephalitis. If your own immune system causes inflammation by attacking the brain, it’s referred to as autoimmune encephalitis.

Keep in mind that in some cases there isn’t a clear cause of encephalitis. It can become life-threatening if not diagnosed and treated quickly as it affects different individuals uniquely.
