Transient Ischemic Attack
For this paper I researched strokes, more specifically, transient ischemic attacks or TIA’s. The difference between a transient ischemic attack and a stroke is that the blockage with a TIA is transient, or in other words temporary. A transient ischemic attack is what occurs when the blood flow to part of the brain is either blocked or reduced. This usually happens because of a blood clot. After some time the blood begins to flow normally again and the symptoms dissipate. According to WebMD, “people call a TIA a mini-stroke, because the symptoms are those of a stroke but don 't last long”. This is a very important health concern because most often a TIA is somewhat of a warning and means that you are very likely to have a stroke in the future. …show more content…
Most of these risk factors are ones that can be controlled and although many people don’t think about strokes until they have one or realize they are at risk, it’s important to be aware and take preventative measures before it’s too late. Though most risk factors are in your control, there are a few that are not. These risk factors include your age, race, gender, and also your family 's health history. As you grow older you become more at risk for a stroke and generally women have a higher risk of having a stroke in their lifetime than men do. Also African Americans, Native Americans, and Alaskan Natives all are at higher risk than other races. Lastly your risk of stroke is much higher if someone in your immediate family such as a parent or sibling has a history of stroke.
According to the American Stroke Association, blood clots are the most common cause of transient ischemic attacks. Also blood clots can be a result of atherosclerosis which is hardening of the arteries, a heart attack, or abnormal heart rhythms. This blood clot can block the blood flow that goes to your brain and within seconds your brain cells are affected by this blockage. This then leads to the symptoms in the parts of your body that are controlled by the affected cells. Once the clot dissolves the blood flow returns back to normal and the symptoms being to go

2065 Words | 9 PagesIntroduction: Imagine sitting there and then suddenly an overwhelming sense of fear washes over you. All that is possible is sit there and be a distant spectator to your surroundings unable to interact for the moment. After seconds that feel like an eternity pass you then come to gaining back full awareness, but still lacking the ability to breathe or speak correctly. This is an example of what a seizure feels like and a significant portion of the population, about 1%, suffer from a condition known as epilepsy, or reoccurring seizures (10).
Generalized Seizures
797 Words | 4 PagesSeizures occur due to an abnormal electrical charge in the brain. There are two different types of seizures: generalized and partial seizures. They are classified as two different groups because of where and how they begin. Generalized seizures begin with an electrical charge that affects both sides of the brain at one time. Partial seizures begin with one electrical impulse that only affects a small part of the brain.
Second Impact Syndrome Research Paper
744 Words | 3 PagesI am doing The Second Impact Syndrome it was when the brain swells rapidly and catastrophically, after a person suffers a second concussion before symptoms of an earlier one have subsided. This injury only happens in football. Second impact may be relatively minimal and not involve contact with the cranium. Impact disrupts the brain’s blood autoregulatory system, leading to swelling, increasing intracranial pressure. This second blow may occur minutes, days or weeks after an initial concussion,and even the mildest grade of concussion can lead to SIS.

Healthcare Disparities In Health
898 Words | 4 PagesIntroduction Disparities in health are an inequality that occurs in the provision of healthcare and its accessibility across different dimensions including location, gender, ethnicity, age, disability status, citizenship status and socioeconomic group (Ubri & Artiga, 2016; Wallerstein & Durran, 2006). According to the health Resources and Service Administration of United States, health disparities are defined by population specific differences in the presence of disease, health outcomes and the accessibility to healthcare. Urbi and Artiga (2016) indicates that disparities in healthcare provision not only bring impacts to the group facing disparities, but also limit overall improvements in quality of care and population health as well as resulting
Absence Seizures: A Case Study
741 Words | 3 PagesMoreover, typical absences usually last 9–12 s (Hooge, & De Deyn, 2001). Indeed, mutations of genes coding for GABA A receptors and T-type calcium channels have been linked to AS. More recent studies have found that Glucose transporters might also be linked to AS, however data is limited in this respect and offers further room for exploration. The pathophysiological theories hypothesized to date, have clearly always recognised the contribution of two forebrain structures, the thalamus and the cerebral cortex, and their fundamental roles in the generation of seizures.

Epilepsy Personal Statement
638 Words | 3 Pages“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” - World Health Organisation, 1946. Although there have been a number of ground breaking discoveries in science as a whole I strongly believe more can be done within neurology. Epilepsy affects more than 500,000 people in the UK that is almost one in every 100 people. I wish to study neuroscience as I would like to look into conditions such as this but also explore into neuroaesthetics. Having a close family member being diagnosed with epilepsy, I have been exposed to the fundamental importance of how to deal with seizures.
The Framingham Heart Study
694 Words | 3 PagesThe number one killer in the United States today is heart disease or also known as cardiovascular disease (U.S. National Library of Medicine, 2015). As death rates begin to rise due to cardiovascular disease, in 1948 the Framingham Heart Study became a joint project of the National Heart, Lung, and Blood Institute and Boston University to pinpoint the most common factors that play a role in cardiovascular disease and strokes (Framingham Heart Study, 2015). Over several years, the Framingham study has identified several risks factors that are believed to increase the likelihood of a person being diagnosed with cardiovascular disease. These risk factors include high blood pressure, high cholesterol levels, smoking, obesity, diabetes, and physical
Symptoms And Definition Of Aneurysm

There are other rare causes of aneurysms. Mycotic aneurysms are caused by infections of the artery wall. Tumors and trauma can also cause aneurysms to form. Drug abuse especially cocaine can cause the artery walls to inflame and weaken.

Issue 1 - Thrombolysis A stroke, is the “rapidly developing signs of focal (or global) disturbance of cerebral function with symptoms lasting 24 hours or longer” (World Health Organisation,1998). In the event of a stroke blood supply to the brain is occluded by a thrombus or an embolus from the heart (Fitzpatrick and Birns,2004).
