A concussion
is a traumatic brain injury that affects your brain function. Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination. Concussions are usually caused by a blow to the head.
What part of the brain is affected by a concussion?
The parts of the brain that are most commonly affected in traumatic brain injury are the
frontal and temporal lobes
. And part of the reason for that is that they’re up against bone, and it’s fairly rigid and rough bone.
What happens if you hit your head with your hands?
Trauma to the brain
may also cause a haemorrhage , or bleeding inside the skull or brain
. Without immediate treatment, this condition is deadly, as is a hematoma, or blood clot, that forms from the escaping blood.
What is the difference between a concussion and a traumatic brain injury?
A traumatic brain injury (TBI) occurs from sudden trauma which causes damage to the brain. TBI can happen when the head suddenly and violently hits an object or when an object pierces the skull and enters brain tissue.
A concussion, which is common in physical contact sports, is a form of brain injury
.
What is an injury that is defined as injury to the brain?
Traumatic brain injury (TBI)
is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull.
What is a hematoma in the brain?
Overview. An intracranial hematoma is
a collection of blood within the skull
. It’s most commonly caused by the rupture of a blood vessel within the brain or from trauma such as a car accident or fall. The blood collection can be within the brain tissue or underneath the skull, pressing on the brain.
Is concussion a brain injury?
A concussion is a type of traumatic brain injury
—or TBI—caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth.
What part of your brain is in the back of your head?
Cerebellum
. The cerebellum (“little brain”) is a fist-sized portion of the brain located at the back of the head, below the temporal and occipital lobes and above the brainstem. Like the cerebral cortex, it has two hemispheres.
Can you have brain damage from a concussion?
A concussion is a mild traumatic brain injury. This can occur after head trauma and
can result in brain damage or an altered mental state
. Post-concussion syndrome is a disorder affecting multiple systems in your body. It can last months and result in symptoms such as dizziness or headache.
Can you get a brain tumor from hitting your head?
One long-term study found that because brain tumors are relatively rare,
the individual risk of a brain tumor from trauma to the head is small and is not associated with the severity or location of the head injury.
How do I know if I have brain damage?
| Physical Thinking and Remembering Sleep | Dizziness or balance problems Feeling slowed down Sleeping more than usual | Feeling tired, no energy Foggy or groggy Trouble falling asleep | Headaches Problems with short- or long-term memory | Nausea or vomiting (early on) Trouble thinking clearly |

Can hitting your head cause a brain bleed?
Intracranial hematomas (brain bruising and bleeding) may occur after hitting your head
. The force of the impact often ruptures the brain’s delicate blood vessels, causing blood to fill the intracranial space.
What are the three types of TBI?
There are three basic levels of TBI injury:
mild, moderate, and severe
.
What are some examples of traumatic brain injuries?
- Concussion. Concussions are one of the more common traumatic brain injuries. …
- Edema. …
- Diffuse Axonal Injury. …
- Hematoma. …
- Skull Fracture. …
- Hemorrhage. …
- Hypoxic/anoxic Brain Injury. …
- Stroke.
What are the 4 categories of concussion symptoms?
The signs and symptoms of concussion reported within 1 to 7 days post injury (see Table 3-3) typically fall into four categories—
physical (somatic), cognitive, emotional (affective), and sleep
—and patients will experience one or more symptoms from one or more categories.
What is focal brain injury?
Focal brain injury refers to
areas of localised damage and includes contusions and lacerations
. Contusions are multiple small haemorrhages in the surface layers of the brain (i.e. bruises). They can occur at the site of impact and/or at the opposite side of the brain from the site of impact.
What is the most common type of brain injury in this country?
Concussions
are the most common type of TBI. You can take steps to lower your risk of accidents that cause TBIs.
What is the most severe brain injury?
Diffuse Axonal Injury (DAI)
Diffuse axonal injuries are one of the most severe types of traumatic brain injury. They occur when the brain is shaken or twisted inside the skull.
What are the 4 types of brain bleed?
Intracranial hemorrhage encompasses four broad types of hemorrhage:
epidural hemorrhage, subdural hemorrhage, subarachnoid hemorrhage, and intraparenchymal hemorrhage
. Each type of hemorrhage results from different etiologies and the clinical findings, prognosis, and outcomes are variable.
What is extradural haemorrhage?
An extradural haematoma is
a collection of blood in the ‘potential’ space between the skull and the outer protective lining that covers the brain (the dura mater)
. It usually occurs because of a head injury. It is a serious condition and emergency treatment is needed. An operation to remove the haematoma may be needed.
What is a bilateral subdural hematoma?
A subdural hematoma is
a collection of blood outside the brain
. They’re usually caused by serious head injuries. Bleeding and added pressure on the brain from a subdural hematoma can be life-threatening. Some stop and go away suddenly; others need surgical drainage.
What are the different types of concussions?
- Grade 1: Mild, with symptoms that last less than 15 minutes and involve no loss of consciousness.
- Grade 2: Moderate, with symptoms that last longer than 15 minutes and involve no loss of consciousness.
- Grade 3: Severe, in which the person loses consciousness, sometimes for just a few seconds.
When does concussion occur?
A concussion occurs
when your brain bounces or twists inside your skull or experiences rapid, whiplash-type back and forth movement that causes it to collide with the inside of your skull
. This brain movement stretches and damages brain cells and leads to chemical changes in the brain.
Are there different kinds of concussions?
3 Types of Concussions
Grade 1, Mild: Symptoms that last less than 15 minutes and entail no loss of consciousness. Grade 2, Moderate: Symptoms that last for longer than 15 minutes and involve no loss of consciousness. Grade 3, Severe: The person loses consciousness.
What is this cerebrum?
The largest part of the brain
. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.
What are motor cortices?
The motor cortex is
an area within the cerebral cortex of the brain that is involved in the planning, control, and execution of voluntary movements
. The motor cortex can be divided into the primary motor cortex and the nonprimary motor cortex. The primary motor cortex is critical for initiating motor movements.
What is a neuron?
Neurons are
information messengers
. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.
