What is the term for a blood clot in the brain?

Intracranial hematomas are the rupture of a blood vessel leading to the collection of blood in brain tissues or empty spaces. There are several types of hematoma: Epidural Hematoma: A blood clot outside of the brain and the dura but under the skull. Subdural Hematoma: A blood clot between the brain and the dura.

What is the term for a blood clot between the brain and the dura?

Subdural Hematoma: A blood clot between the brain and the dura. Subarachnoid Hemorrhage: Bleeding withing the layers of the dura, specifically under the aracnoid layer. Intracerebral Hematoma: Bleeding within the brain tissue itself caused by the rupture of a blood vessel within the brain.

What is a penetrating head injury?

Penetrating injuries can be caused by high velocity projectiles ( such as bullets and fragments) or objects of lower velocity (such as knives or bone fragments). Only 1-2% of TBIs are penetrating head injuries. Closed TBI: An injury in which the dura remains intact. It is further classifies as mild, moderate and severe.

What is a diffuse axonal injury?

Diffuse axonal injury or DAI usually results from rotational forces or violent stopping.Unlike brain trauma that occurs due to a direct blow, DAI is the reult of twisting and tearing of the connections between the cells of the brain.

What are the two types of traumatic brain injuries?

Doctors typically group traumatic brain injuries into two main categories: closed injuries and open (or penetrating) injuries. Closed injuries refer to TBIs that do not fracture the skull. Open injuries, on the other hand, occur when the skull bone breaks or is penetrated, leaving the brain exposed to the elements.

What is the most common type of brain injury?

Concussions are the most common type of traumatic brain injury. When a strong force strikes your head, your brain moves in the direction of the force until it collides with your skull, causing damage.

What is a Traumatic Brain Injury?

A TBI is an injury to the brain that occurs as a result of a bump or blow to the head or from blunt or penetrating trauma. During the impact, the brain crashes back and forth within the skull resulting in bruising, bleeding, and the shearing of nerve fibers known as axons.

What determines the rehabilitation plan for a TBI?

The type of traumatic injury you experience will determine what your TBI rehabilitation plan might entail.

Why is it hard to detect a diffuse axonal injury on an MRI?

The axonal shearing disrupts messages that neurons send, resulting in loss of function. Because most diffuse axonal injuries result in only microscopic tears, they can be hard to detect on an MRI. The severity of symptoms in a diffuse axonal injury depends on how large the tears are and where they are located.

What happens when you hit a head with a TBI?

During the impact, the brain crashes back and forth within the skull resulting in bruising, bleeding, and the shearing of nerve fibers known as axons.

Diffuse axonal injuries are one of the most severe types of traumatic brain injury.

What are the different types of closed head injuries?

Closed head injuries are more complicated and have several different presentations (patterns of signs and symptoms). These are the different types of closed traumatic brain injury: 1 Concussions: These are the most common type of traumatic brain injury. Not too much is known about how concussions work. While concussions are generally considered minor, suffering multiple concussions has been linked to an increased chance of brain conditions later in life. 2  2 Epidural hematomas: These are a particularly dangerous type of traumatic brain injury. Epidural hematomas occur when blood accumulates between the hard covering of the brain and the skull, rapidly putting pressure on the brain. 1  At first, because of the way victims of epidural hematomas respond, it might be difficult to tell the difference between an epidural hematoma and a concussion. 3 Subdural hematomas: Subdural hematomas are similar to epidural hematomas, but they often don't cause noticeable neurological problems as quickly or dramatically. In this case, blood seeps more slowly below the hard covering of the brain, taking more time to build up the pressure. Subdural hematomas are more common in those taking blood thinners and those with alcoholism. 4 Cerebral aneurysm: A cerebral aneurysm is a weak blood vessel in the brain that can burst unexpectedly. There is often no way to determine why an aneurysm ruptures. When an aneurysm ruptures spontaneously, it's commonly called a hemorrhagic stroke.

What is the most dangerous type of brain injury?

Epidural hematomas: These are a particularly dangerous type of traumatic brain injury.

What is a brain contusion?

A contusion is simply a bruise—a mild form of bleeding under the skin. Brain contusions are similar to concussions, and often occur in conjunction with them. If a brain contusion does not stop bleeding on its own, it may need to be surgically removed.

What is second impact syndrome?

Sometimes called a recurrent traumatic brain injury, the effect of second impact syndrome depends on the location of the injury, the severity of the first injury, and the degree of trauma sustained. A second impact is more likely to cause severe brain damage than a first, even if the victim does not lose consciousness.

What is a penetrating injury?

A penetrating injury occurs when an object penetrates the skull and brain. These injuries can be fatal if not promptly treated, because they often cause severe bleeding, blood clots, disrupted oxygen supply to various brain regions, and other immediate side effects.

What is coup-countrecoup brain injury?

A coup-countrecoup brain injury occurs when there is significant impact to the brain that causes the brain or skull to slam into the opposite side of the site of impact. The result is damage at the impact site, as well as on the opposite side of the brain. Though any injury can cause a coup-contrecoup brain injury, these incidents are often especially violent, producing immediate symptoms. Serious car accidents, blows to the head, forceful falls, and acts of violence are particularly adept at producing these injuries.

Is a non-traumatic brain injury devastating?

Non-traumatic brain injuries can be equally devastating. To learn more about non-traumatic brain injuries, see " Types of Acquired Brain Injuries .".

What is an open TBI?

Open TBI (also called penetrating) results when the scalp/skull is broken, fractured, or penetrated. This may occur when a foreign object (e.g., a bullet) goes through the skull, enters the brain, and damages specific parts of the brain.

What happens when a TBI is closed?

Closed TBI results when an outside force impacts the head, but the skull is not broken, fractured, or penetrated. This may occur, for example, when the head strikes the windshield or dashboard in a car accident. Damage is typically widespread or diffuse. Symptoms following a closed TBI vary depending on the extent of the damage to the brain.

What is a TBI?

Traumatic brain injury also knows as TBI usually results from an external and violent blow or jolt to the head, causing a complex injury to the brain. The majority of all reported traumatic brain injuries result from an automobile accident. In these instances where a TBI is sustained, brain tissue is damaged by direct penetration, swelling or a lack of oxygen. The most serious traumatic brain injuries result in long-term complications or death.

What is a TBI in the skull?

Crushing Injuries. These types of injuries result when the skull and brain are compressed between to hard objects. Damage to the base of the skull, cervical spine, and/or brain stem commonly occur from these types of TBI. Such a traumatic brain injury can occur during an automobile accident, when a head is caught between two hard objects.

What is a closed head injury?

Closed Head Injuries: This is the most common of traumatic brain injuries, especially in automobile accidents. A closed head TBIcan result in the brain twisting, colliding and/or bounding within the cranial cavity due to rapid head movement and can cause contusions (bruising), internal bleeding, or damage to the nerve fibers. Such a traumatic brain injury can occur during an automobile accident when the skull strikes, an object such as a steering wheel, headrest or windshield. When a moving head strikes a stationary object such as the headrest or steering wheel, the head may come to a quick stop, however, the brain continues its movement striking the interior of the skull which may bruise the brain tissue and/or cause bleeding/brain hemorrhage, neither of which is visible at the time of the automobile crash.

Can a penetrating injury occur with a closed head injury?

Open Wound (Penetrating) Injuries. These types of brain injuries are less frequent but can occur simultaneously with closed head injuries. These types of injuries, which can result from penetrating traumatic events such as stabbings, gunshot wounds, or even extreme sporting accidents, risk exposure of the brain through skull breakage. Such a traumatic brain injury can occur during an automobile accident, when a moving head strikes a stationary object such as the headrest or steering wheel, and a piece of skull penetrates the brain tissue.

What is a TBI?

A traumatic brain injury, or TBI, can happen when there is a blow to the head. The injury can be penetrating, such as a gunshot wound, or a non-penetrating injury, such as being struck in the head in a car accident. Traumatic brain injuries vary in severity. Many people recovery from TBIs within days and more severe forms can cause permanent brain ...

What are the causes of TBI?

Traumatic Brain Injury. Falls and car accidents are two of the top causes of traumatic brain injuries (TBIs). When you take a severe blow to the head, your brain hits against the skull. The impact can cause brain damage. Concussions are the most common type of TBI. You can take steps to lower your risk of accidents that cause TBIs.

The severity of the head injury is determined by several different factors, such as loss of consciousness, certain neurological symptoms that happened at the time of the injury, loss of memory for the injury and time surrounding it, and abnormalities on head CT or brain MRI.

How long does it take to recover from a TBI?

People with mild TBIs are expected to improve and return to their pre-injury functioning within days to a few months. Some people with mild TBIs have few concerns and never seek treatment.

What does it mean when a TBI is closed?

A closed TBI means an outside force causes a blow or jolt to the head that did not penetrate the skull. This impact injures the brain, causing it to swell. Open: Healthcare providers may call open TBI a penetrating TBI. This injury occurs when a bullet, knife or something else goes through the skull.

How do you know if you have a TBI?

TBI symptoms vary depending on how severe the injury is. A key sign is loss of consciousness (passing out) after a blow. Some people feel dazed for a couple of minutes and others are unresponsive for long periods ( coma or persistent vegetative state).

What Is A Traumatic Brain Injury?
