Traumatic Brain Injury WUT2 Task Western Governors University A. Investigated Disease Process The disease process I will be reviewing is traumatic brain injuries. A traumatic brain injury occurs when sudden trauma occurs to an individual’s brain. Traumatic brain injuries are considered closed or penetrating. Traumatic brain injuries are categorized as mild, moderate or severe based on the amount of damage that occurs to the brain. (ninds.nih.gov, 2015) A1. Pathophysiology To understand traumatic brain injuries, we must first discuss the numerous causes of brain injury. When injury occurs to the brain, the patient encounters the primary injury that is directly related and occurs at the time of the injury. Secondary injury …show more content…
Skull fractures are another type of traumatic brain injuries. Closed skull fractures can lead to brain hematomas and damage to the cranial nerves. Open skull fractures can occur from a direct blow or a penetrating injury. Open skull fractures related to direct blows often have increased injures related to the skull fragments being depressed into the brain or the vascular structures of the brain. 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
With the latter of the two of them all being the more frequent causes of brain injury. It has never been clear exactly on how much damage is done and how the symptoms are caused when the injury happens. There has been reported that there is cellular damage that happens in the concussed brain. Currently it is thought that structural and neuropsychiatric factors may be responsible for these effects.
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).
Explain the difference between a traumatic brain injury and other forms of acquired brain injury.
Concussions are mainly caused by the gelatinous brain being forcefully hit against the inner walls of the skull. A violent blow to the head or upper body can cause the brain to shift in various directions in a skull. Sudden starting and stopping of the body can also purpose this type of violent movement within the head. This is why brain injuries can originate from violent shaking of the head or car accidents. Participating in contact sports, being involved in military combat, and having previous concussions are all high risk factors for brain damages.
When someone receives a concussion his or her brain processes change. In the brain, after the hit, the nervous system suffers from a type of paralysis. The brain itself is allowed to move somewhat freely inside the skull. A hit will cause the brain to bruise slightly where the forehead is and right at the top of the neck. Physical symptoms that result
Head injuries typically fall under one of two categories based on how the injury was sustained; an injury due to a blow or shaking. Head injuries that fall under the category of occurring by a blow can be sustained by; a motor vehicle accident, a fall, a physical assault, or a sports related injury. Head injuries that are caused by shaking are typically sustained by violent shaking. The types of head injuries that can result from these incidents include; hematoma, hemorrhage, concussion, edema, skull fracture, and diffuse axonal injury.
(Abreu, 2016) 3) Major brain trauma can occur from multiple hits to the head, bleeding in brain requires immediate operation, or could lead to death. (Transition: Now that you have some knowledge about football related injuries, the world is currently looking for new ways to make the sport safer. III.
A Hematoma which may be caused by a mild head trauma, if an older adult. You are likely to have a serious head injury even if there is no open wound, bruise or other outward sign of damage. A Hematoma may occur as a subdural, epidural, and intracerebral Hematoma.
Some of the types of head injury include a diffuse axonal injury, concussion (which is also called a TBI), and second impact syndrome. Strong rotation or shaking of the head as with Shaken Baby Syndrome is one cause of diffuse axonal injury. Car accidents may also be a cause of the injury (Brain Injury Association of America). A concussion may be caused by blows to the head, gunshot wounds, violent shaking of the head, or force from a whiplash type injury (Brain Injury Association of America). ?Second Impact Syndrome, also termed ?recurrent traumatic brain injury,? can occur when a person sustains a second traumatic brain injury before the symptoms of the first traumatic brain injury have healed? (Brain Injury Association of America).
Traumatic brain injury (TBI), or intracranial injury, is a medical diagnosis which refers to closed or penetrative damage to the brain that is caused by an external source. Every year, TBIs affect approximately 150-250 people in a population of 100,000 (León-Carrión, Domínguez-Morales, Martín, & Murillo-Cabezas, 2005). The leading causes of TBI are traffic accidents, work injuries, sports injuries, and extreme violence (León-Carrión et al., 2005). TBI is most often fatal when the cause is an injury due to the use of firearms, a traffic accident, or a long fall (León-Carrión et al., 2005). However, fatality rates and rates of occurrence differ in various countries due to
It poses a major health problem in higher income countries as it is the leading cause of mortality and disability in young people [1]. Brain trauma can be caused by a direct impact or by acceleration alone. In addition to the damage caused at the moment of injury, brain trauma causes secondary injury which includes a variety of events that take place in the minutes and days following the injury. These processes, which include alterations in cerebral blood flow and the pressure within the skull, contribute substantially to the damage from the initial
Head injury is defined as any shock to the head received in the skull, whatever its violence. Head injuries are very common. But those severe (brain damage) are rare and represent the first cause of death among 15-25 year olds. Head injuries are classified into 3 groups (low, moderate, severe) and require a different medical care.
This trauma is caused only when some external force is used on the cranium i.e. a blow is given to the cranium. The presence of trauma and haemorrhage indicate towards signs of struggle and proves the prosecution theory of homicide.
Severe head injuries were also classified according to pathogenesis, pathomorphology, pathophysiology, biochemical derangements and brain CT scan findings particularly lesion density.
The brain is a fragile organ. Although it is protected by the scalp, skull and the three layers of meninges there is still a possibility that it can still be injured. Head injury occurs when an external mechanical force causes brain dysfunction. Penetrating and closed head injuries are the two major types of brain injuries. Penetrating head injuries occur when foreign objects enters the brain and cause damage to specific brain parts. Symptoms vary depending on which part of the brain was damaged. For instance Phineas Gage. A large iron rod was driven through his head, and it destroyed his left frontal lobe. It was said that it changed his personality. After the incident friends did not see him as the “old” Phineas Gage. This case caused neurologist to
