TBIs are divided into four categories. Concussion, contusion, penetrating damage, and anoxic brain injury are the four types.

Concussions are a kind of concussion that occurs.

A concussion is mild brain damage caused by shaking, a head hit, or a fast change in movement, such as whiplash. Concussions are often difficult to detect using imaging tests, but they should still be taken seriously and treated as such.

Concussions may result in headaches, focus issues, memory loss, and disorientation. Concussions are incredibly harmful if you have more than one overtime or get another one before the first recovers. See Second Impact Syndrome for further information.


A bruise of the brain tissue, similar to a bruise on the skin, is known as a brain contusion. They are created by the shattering and spilling of tiny blood vessels, much like any other bruise. This seeping blood beneath the skin generates blue coloration; on the brain, the leaking causes a variety of difficulties, most of which are related to a buildup of pressure.

Any trauma to the head might result in a brain contusion. Discoloration may occur in a car accident when the head collides with the steering wheel, in a slip and fall when the head collides with the ground, or in a sports-related injury when the brain is impacted hard.

The brain may be injured immediately beneath the point of impact, on the other side of the point of contact when the brain slams against the opposing side of the skull, or both during

the impact that creates a brain contusion. These variations in damage location are known as coup and contrecoup injuries.

Contusions, like concussions, may vary in severity from moderate to life-threatening. Severe concussions might result in loss of consciousness, bewilderment, exhaustion, emotional anguish, or agitation. Severe contusions may cause the brain to enlarge, impair oxygenation, and have other significant implications.


When an item pierces through the skull, it causes a penetrating brain injury. The item, or hair, skin, or portions of the skull, may come into touch with the brain as a result. Contact with the brain and force applied to it may significantly injury a concentrated or big area of the brain.

Any external force or item powerful enough to break through the skull may induce a penetrating brain injury, such as:

  • If you slip and fall, your skull may break.
  • A car accident in which something enters the skull and fractures it.
  • A gunshot wound to the head, which is the most common cause of TBI fatality.
  • Injuries caused by excessive force in sports


When the brain does not get enough oxygen to function correctly, anoxic brain damage ensues. Brain cells will begin to die, and brain injury will occur after just four to five minutes without enough oxygen. Because blood carries oxygen to the brain, anoxic brain injury is most often caused by a stoppage of this blood flow.

A blood clot, stroke, heart attack, or major trauma, among other things, might cause a blockage. It’s also conceivable that the amount of blood flowing to the brain is normal, but  the blood itself isn’t carrying enough oxygen. Poisoning, drowning, carbon monoxide  poisoning, choking, suffocation, or anything else that stops the lungs from taking in a normal  number of oxygen molecules might cause this to happen[3].

TBIs that aren’t listed above


A diffuse axonal injury (DAI) is similar to a concussion in that it occurs when the brain moves, but it is often much more devastating. The head moves so quickly with a DAI that the brain stem can’t keep up, causing rips in the brain-spinal cord connections. These rips may range in size from microscopic to enormous, causing varying degrees of brain injury.

Sufficient tears may have highly significant, life-long consequences or even be deadly.

The degree of symptoms from this sort of injury is mostly determined by the brain areas impacted, the severity of the tears, and if any other injuries were experienced as well, such as a contusion or concussion.


Hypoxic brain injury is one form of traumatic brain injury that happens when the brain gets some but not enough oxygen, causing damage. This is frequently accomplished by ineffective suffocation, such as near-drowning, near-hanging, cardiac arrest, carbon monoxide, or exposure to hazardous gases, which results in an inadequate decrease of oxygen to the lungs or blood to the brain.

Hypoxic-ischemic brain damage, also known as stationary hypoxia or ischemic insult, is one kind of hypoxic brain injury.


A second brain injury after a first may produce much more catastrophic damage, just as a scab that has been reopened takes longer to heal. The consequence of second impact syndrome, also known as repeated traumatic brain injury, is dependent on the location of the damage, the severity of the initial injury, and the degree of stress received.

Even if the person does not lose consciousness, a second collision is more likely to produce significant brain injury than a first. Even if you feel OK, get medical attention if you receive  a hit to the head in the months after brain damage. Second concussions are often a quiet killer since both hits may look small at the time.


Mild, moderate, and severe TBI injuries are the three most common types.


A mild TBI is defined as a brief loss of consciousness that lasts just a few seconds  or minutes, if at all. A sufferer doesn’t need to lose consciousness; instead, they may look confused or disoriented. Medical testing may reveal that the brain was not injured in mild TBIs, but this is not always the case. This is why, while diagnosing mild TBIs and  concussions, clinicians pay particular attention to the victim’s mental functioning.

A mild TBI is defined by a loss of consciousness that may last up to a few hours, as well as disorientation that can linger for weeks. Complications from a mild TBI might linger for months or even be permanent. Physical, cognitive, or behavioral issues might all occur. To address these issues, a variety of therapy regimens will be required.

Severe brain damage

The most serious TBIs are caused by crushing impacts to the skull or penetration of the brain. This degree of injury is life-threatening, and the person will not be able to resume their previous lifestyle. While closed head injuries may cause significant brain damage, severe head trauma is usually caused by an open head injury in which the skull has been severely damaged.

A person who has had a traumatic brain injury may have various debilitating symptoms or perhaps be in danger of losing their life in more severe circumstances. These injuries must be addressed carefully since they have a history of claiming lives.

Because traumatic brain injuries cause direct physical injury to the brain, they have devastating physical and  emotional repercussions. In addition to the major health risks that physical brain injury might  pose, cognitive function, personality, and mental state, in general, can all be severely injured.

Memory loss, emotional troubles, communication difficulty, sensory impairment, psychiatric diseases, and more are all examples of this.

What’s more, the effects of severe brain injuries are often permanent. There isn’t much that can be done to heal brain tissue that has been injured. People typically suffer for the rest of their life with the ramifications of brain damage.

That isn’t to suggest there isn’t still hope. Many things may be done to assist patients in controlling their symptoms and coping with the repercussions of a severe traumatic brain injury.
