Free TBI Types of Traumatic Brain Injury Questions and Answers

Question 1

Which type of brain injury occurs when the head is struck by an external force, causing brain movement inside the skull?

Accepted Answer

Closed head injury

Answer

A closed head injury occurs when the head sustains a blow or impact, but the skull remains intact and is not penetrated. The brain moves within the skull, leading to damage from impact against the inner skull surfaces, shearing forces, or swelling. This type of injury can range from mild concussions to severe brain damage.

Question 2

Which traumatic brain injury involves an object penetrating the skull and brain tissue?

Accepted Answer

Penetrating injury

Answer

A penetrating brain injury, also known as an open head injury, occurs when an object pierces the skull and enters the brain tissue. This type of injury can cause localized damage to the brain, as well as potential for infection and bleeding. Examples include gunshot wounds or stab wounds to the head.

Question 3

What is a mild traumatic brain injury typically called?

Accepted Answer

Concussion

Answer

A concussion is the most common type of mild traumatic brain injury (mTBI), resulting from a blow to the head or violent shaking of the body. It causes temporary disruption of normal brain function, leading to symptoms like headache, dizziness, confusion, and memory problems. While often temporary, repeated concussions can have serious long-term effects.

Question 4

Which TBI type involves injuries at the site of impact and on the opposite side of the brain?

Accepted Answer

Coup-contrecoup injury

Answer

A coup-contrecoup injury occurs when the brain impacts the skull at the site of the initial blow (coup) and then rebounds to strike the opposite side of the skull (contrecoup). This dual impact causes damage at two distinct locations within the brain. It is common in acceleration-deceleration injuries, such as those sustained in car accidents.

Question 5

What injury results from extensive brain tissue damage caused by shearing forces during rapid acceleration or deceleration?

Accepted Answer

Diffuse axonal injury

Answer

Diffuse axonal injury (DAI) is a severe form of traumatic brain injury caused by strong shearing forces that occur during rapid acceleration or deceleration of the head. These forces tear and stretch the long connecting fibers of the brain (axons), disrupting communication between brain cells. DAI often leads to widespread brain damage and can result in prolonged coma or persistent vegetative state.
