A Subarachnoid Hemorrhages

Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke.

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

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

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

This letter is in regards to some concerns for possible brain injuries that are likely to occur when playing sports but specifically rugby. The brain is the most essential function of the human body. In order to not only conduct an analysis but also understand the brain and we must complete a detailed training on how the brain is affected when a concussion takes place. According to several health professionals it only takes one brain injury to adjust the behavior of a person. Many hits to the head can take a devastating tool on the brain. There are studies showing that Rugby Football is destroying the brain of rugby football players. A common head injury is a Chronic Traumatic Encephalopathy (CTE) is a repetitive brain injury. The initial cause is occurs when the brain comes in

A traumatic brain injury (“TBI”) occurs when the brain is somehow injured, rattled, or wounded from an external source of force. The means of acquisition and the severity of TBIs are unique to each patient; therefore, symptoms and rehabilitation can vary greatly depending on the patient’s condition following the incident and how they sustained the injury. The severity of a TBI is generally classified into one of three categories: mild, moderate, or severe, and this type of diagnostic criteria influences how a patient with TBI is treated by medical staff and rehabilitation specialists. TBIs can affect a specific part of the brain that was directly impacted, leaving the patients with only one or a few areas of impairment, or the damage can

According to our American Red Cross Nursing Assistant text a cerebral vascular accident, C.V.A., or stroke occurs when blood flow to a part of the brain is interrupted. The loss of blood supply results in the death of brain cells. (Page 91) When your brain starts to die the bodily functions the brain controls can be affected. The affected bodily functions depend on what part of the brain does not receive oxygen. Web MD says damage “can occur within 3-4 minutes if not treated.”

Cerebrovascular accidents, or strokes, will lead to brain damage that affects the functioning of executive function, memory, language, visuospatial performance and emotional states. Corresponding vertebral arteries and carotid arteries provide blood to the brain from the heart that the carotid arteries are internal and external sections of the thyroid cartilage. Where the optic nerve rests the internal artery distributes into the anterior and middle cerebral arteries. The vertebral arteries arise through the spinal vertebrae and meet the lower pons to form the basilar artery. The brain receives 15% to 20% of the oxygenated blood from the heart and can only endure fleeting interruptions of blood flow before neural operations

It is “a sudden loss of function resulting from disruption of the blood supply to a part of a brain” (Hincle & Cheever, 2014). The type of stroke Patient S experienced was assumed to be from hyperlipidemia. An atherosclerotic plaque can form in the large blood vessels in the brain. When the plaque become big enough, it can rupture or a small bit may break off and flow into small arteries, which may block the smaller artery. If the artery is occluded, blood cannot flow to certain parts of the brain and an ischemic stroke can occur. Hypertension is a major risk for strokes as well as atrial fibrillation. These diseases increase the risk of an emboli or plaque

This patient most likely has a extradural (epidural) hematoma and the temporal fossa is the most common site of this type of hematoma caused by “injury to the middle meningeal artery or vein”(McCance & Huether, 2014, p. 584). “Expanding high-volume epidural hematomas can produce a midline shift and cause herniation of the brain. Compressed cerebral tissue can impinge on the third cranial nerve resulting in pupillary dilation and contralateral hemiparesis or extensor motor response”(Price, 2014, p. 3). Extradural hematomas are medical emergencies and surgical intervention is needed to remove the clot and reduce the pressure on the brain. Whether treated or untreated, this type of hematoma has an elevated risk of brain damage. However, left untreated, patients with extradural hematomas have a high risk of

Extra-axial hemorrhages indicate that these injuries occur outside the substance of the brain itself. Other injuries that can occur are damage to the neck, spine, and possible retinal hemorrhages or detachment.

combined could be a very possibly be the reason for the cerebrovascular accidents suffered by

It is also unclear if it is the brain injury itself that causes the result and if it is the same for healthy people.

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
