Thermodynamic Stroke

1579 Words7 Pages

Stroke occurs when the blood supply to a part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells (National Institute of Neurological Disorders and Stroke, Stroke Information Page, 2013). There are two types of stroke: ischemic and hemorrhagic. An ischemic stroke is caused when there is a blockage in the blood vessels to the brain (AHA/ASA, 2012). Ischemic strokes account for 85% of strokes (Go, Mozaffarin, Roger, Benjamin, Berry, Borden, et al., 2012). A hemorrhagic stroke is caused when an artery is ruptured or leaks blood in the brain (National Center for Chronic Disease Prevention and Health Promotion, Division for Heart Disease and Stroke Prevention, Types of Stroke (2013). Another form of strokes are Transient Ischemic Attacks (TIAs) often referred to as “mini strokes” (AHA/ASA, 2012). These are often warning signs that a stroke could occur if an individual’s lifestyle or risk factors are not modified. During a TIA, there is a temporary decrease in blood supply to the brain; symptoms usually last less than 24 hours before disappearing (NSA, 2012).
Epidemiology
Fifteen million people suffer stroke worldwide each year (World Health Report, 2002). High blood pressure contributes to more than 12.7 million strokes worldwide (WHR, 2002). Europe …show more content…

About 87% of strokes are ischemic in nature, and are usually caused by the obstruction of an artery by a thrombus or an embolus (Moheet & Katzan, 2011). On the other hand, hemorrhagic strokes which account for 15% of all strokes result from either vascular anomaly or a long history of hypertension. Sixty-five percent (65%) of hemorrhages occur in the basal ganglia-thalamus; 15% in pons. Hemorrhagic stroke is usually progressive and deadly and can evolve over hours to days (Mayo Clinic,

    Brain Aneurysm Four major blood vessel supply blood to the brain. They join together at the circle of willis at the base of the brain. Smaller arteries leave the circle and branch out to supply brain cells with oxygen and nutrients. Artery junction points may become weak causing a ballooning of the blood vessel wall to potentially form a small sac or aneurysm. Cerebral aneurysms are common but most are asymptomatic and are found incidentally at autopsy.

Traumatic brain injury is caused by a trauma/impact to the head that usually takes places in car accidents, while playing sports or performing an activity, from falling or during an assault. TBI in babies are usually associated with abuse, while toddlers usually suffer TBI from falling. School aged children sustain injuries most frequently from bicycle accidents, while older peers injuries are related to sports or car accidents. Car accidents are the most common cause of TBI in adults and adolescents.

    A hemorrhagic stroke is a result of bleeding into the brain tissue, usually as a result of a burst blood vessel, resulting in neuronal death and damage to brain structures. The initial brain bleed (hematoma), often leads to increased intracranial pressure (mass effect), which is severe enough, can compress brain tissue and lead to restriction of blood flow, and therefore subsequently ischemia and cell death (Keep et al., 2012). Overall, hemorrhagic strokes are less common, with approximately 10-15% of all strokes being classified in this category but tend to have a higher mortality rate, possibly due to the tendency for these strokes to be more severe with poorer outcomes. A stroke can occur in any area of the brain, depending on the blood

    According to Centers for Disease Control and Prevention falls are the leading cause of brain injuries. While violent falls are definitely a matter of concern, less dramatic falls should never be overlooked. Whether you suffer an injury from a minor topple or a serious fall, ignoring the signs of a head injury can have life altering consequences. Symptoms Although a brain injury from a fall takes place on impact, some symptoms don't appear until the bleeding or swelling has reached a certain degree. However, loosing consciousness, becoming confused or becoming sluggish immediately after falling are all indication of a serious head injury.

    This is where the injury to the brain is caused by an alternative condition other than a traumatic injury to the brain itself. Examples of these conditions are in instances where the brain is deprived of oxygen in which cases brain tissue begins to die. It can also be a condition in which the brain tissue is directly attacked. Specific examples would include a stroke, heart attack, drug overdose or severe brain infections such as meningitis, just to mention a few. Finally, the vegetative state can be a as a result of progressive brain damage.
