What Is Subdural Hematoma?

Contrary to popular belief, a concussion is not a bruise to the brain caused by hitting a hard surface. Indeed, no physical swelling or bleeding is usually seen on radiological scans. The injury generally occurs when the head either accelerates rapidly and then is stopped, or is spun rapidly.

A concussion is caused by a bump, blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain. Not all blows or jolts to the head result in a concussion. The severity of a concussion can range (CBD,

Hemorrhagic strokes may be intracerebral (within the brain) or subarachnoid which occur from an aneurysm or atypical blood vessels.

sudden jolt or bashing to the head. Concussions can also be caused by falling and hitting

Different types of intracranial hemorrhages can occur due to injuries to the skull, either directly or indirectly. Epidural hematomas occur when a direct blow to the skull causes injury to the dural arteries or veins that lead to bleeding that accumulates between the dura matter and the skull. If the dural artery is injured, rapid deterioration of the patient neurologic status can occur. As the size of the epidural hematoma increases, the surrounding brain tissues is damaged due to the compression from the pressure of the blood accumulation. The patient may experience a dilated pupil on the side of the injury due to compression of the third cranial nerve. The patient may also complain of a severe headache, visual disturbances and weakness on the opposite side of the injury. If bleeding continues and increases the intracranial pressure, leading to brain shift or herniation of the brain stem which is irreversible and leads to hypertension, bradycardia and respiratory arrest. This trio of symptoms is called the Cushing’s Triad. Epidural hematomas can continue

A closed head injury is where the brain is injured and blood vessels may be ruptured as a result of blow to the head by the force against the skull. In this type the skull is not fractured.

A concussion is a type of traumatic brain injury caused by a blow to the head, fall, or any other sudden movement that shakes or jars the brain inside of the skull (Healthwise

Concussions, which can be also known as a minor head trauma or mild traumatic brain injury. They are defined as a head injury because of temporary loss in brain functions which can be shown by a variety of signs. These include headaches, feeling in a fog, and emotional changeability. Common causes for these types of injuries are sports injuries, bicycle accidents, car wrecks, and falls.

How an injury to the head can do damage to the brain varies. Brain swelling and disruption of blood supply are some direct causes of damage (Kolb & Whishaw, 2009). However, neurological damage develops after (also known as secondary injuries) the immediate moment of impact (Ghajar, 2000). In other words even minor head injuries can lead to lasting disabilities and that the injuries are amassed. Meaning that a minor injury can result in a major impairment (Ponsford, Sloan, & Snow, 2012).

According to the CDC, a concussion is a type of traumatic brain injury. Concussions are usually caused by an impact or blow that thrusts the brain back and forth inside the skull. The impact can happen to the head, or it can be the result of a blow to the body. When the brain shifts in the skull, it can twist, stretch and impair healthy brain cells.

Subdural or Epidural bleeding – as bleeding grows it pushes on brain which will mean you have difficulty communicating and moving.

The phrase concussion details an injury to the brain occur from an shock to the head from someone(Cunha 1). A calm concussion can affect a loss of awareness feeling dazed or a actual terse loss of consciousness from taking a blow to the head or being knocked down(Cunha 2). A harsh concussion can affect delayed loss of consciousness. A concussion outcome starting with a head shot that is close is a type of injury and do not consist of trauma when there is bleeding in the skull under it(Stoppler 3).

Concussions are one of the most serious, yet overlooked injuries in the world. The term concussion is defined as a temporary unconsciousness caused by a blow to the head. The term is also used loosely of the aftereffects such as confusion or temporary incapacity. Although concussions usually are caused by a blow to the head, they can also occur when the head and upper body are violently shaken. Injuries like these can cause a loss of consciousness, however most concussions do not. This makes concussions

Extradural hematoma (Epidural hematoma): “Bleeding between the dura mater and the skull caused most commonly by motor vehicle accidents and occasionally by falls and sporting accidents”(McCance & Huether, 2014, p. 584). It usually results from a “brief linear contact force to the calvaria that cause separation of the periosteal dura from bone and disruption of interposed vessels due

In a subarachnoid hemorrhage, bleeding occurs within the space between the brain and the skull. This type of stroke accounts for about 7% of all strokes. A subarachnoid hemorrhage is often signaled by a sudden thunderclap headache thats more severe than any you have ever felt. About half of all people who experience a subarachnoid hemorrhage die. Half of those who survive are left
