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,

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

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.

Severe – The individual will lose consciousness for more than 24 hours and may need life support machinery to help them breathe, the brain may starve from oxygen and cause injury. This can lead to loss of mobility, communication, talking and eating and drinking and may mean they become nil by mouth.

This is not to be confused with the total depletion of oxygen to the brain called cerebral anoxia. Consequently, Cerebral Hypoxia can be caused by many scenarios like carbon monoxide poisoning, breathing in smoke, and choking. Furthermore, Other instances deal with oxygen and nutrient deprivation such as drug overdose, before all the way to after childbirth, and stroke. We now know what causes this variant of Hypoxia, but the next step is to identify this condition’s symptoms.

“A traumatic brain injury (TBI) is a disruption in the normal functioning caused by a blow or jolt to the head or a penetrating injury” (Owens, 2015). People who suffer from a TBI may have trouble with speaking or understanding language. According to Kathleen bell MD from the “living with traumatic brain injury video”, They may have “problems with double vision difficulty with moving about the most common problems that people have and this stretches across mild to more severe brain injuries is problems with thinking and problems with managing behavioral emotions” (Living with a Traumatic Brain Injury, 2012.) There are three main types of brain injuries: contusion, axonal injury, and bleeding in the brain. A contusion to the brain is essentially

 In Europe, there are approximately 650,000 deaths yearly due to stroke.  In China, stroke sufferers are estimated to be about 1.3 million yearly, and more than half of them are left with disabilities. What Causes Stroke  Among those older than 60 years of age, stroke is predominantly due to the presence of heart disease while in those who are younger, sickle cell disease and hypertension (or increased blood pressure) are the leading causes.  Approximately 12.7 million cases of stroke around the world are caused by high and uncontrolled blood pressure.

Background Stroke or cerebrovascular accident (CVA) is the prompt loss of brain function due to disturbance in blood supply. Stroke cuts off the supply of oxygen and glucose which powers the ion pumps maintaining these gradients. Calcium plays an important role in intracellular and extracellular metabolism.

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.

Sometimes deep hemorrhages can expand into the ventricles – the fluid filled spaces in the center of the brain. Subdural hemorrhage (SDH): Subdural hemorrhage (SDH) is a collection of blood accumulating in the potential space between the dura and arachnoid mater of the meninges around the brain. Extradural hemorrhage (EDH): An extradural hemorrhage (EDH), also known as an epidural hemorrhage, is bleeding between the inside of the skull and the outer covering of the brain (called the "dura"). Subarachnoid hemorrhage (SAH): Subarachnoid hemorrhage (SAH) is a serious, life-threatening type of stroke caused by bleeding into the space surrounding the
