Subarachnoid hemorrhage

Most people could probably guess that heart disease and cancer are the leading causes of death, but many may not know that strokes are the fourth leading. Strokes are also one of the leading causes in long-term adult disability. A stroke occurs when there is a clot in a blood vessel or an artery located in the brain, interrupting or severely reducing blood flow to the brain, preventing it from getting the oxygen it needs. There are two different types of strokes, and there are multiple types…

Introduction: Today there are many causes of death, one of which is strokes. Strokes, although not the leading cause of death, are still in the top ten causes; in fact, they are the fifth leading cause of death. Over one hundred thousand people die from strokes; however, not all stroke victims suffer from death. There are over 700,000 people who suffer from a stroke in the US, and although a great percent survives the initial stroke, as time goes on stroke victims risks of death increases.…

1. A 35-year-old male has come to see you because he is urinating, by his estimate, about 8L/day. He is constantly thirsty and drinks as much cold water as he can every day. His sleep is disrupted because of the need to urinate throughout the night. During your assessment, you learn he had several concussions playing college sports. He was recently involved in a car accident in which the airbag deployed and knocked him out. You test his urine and the specific gravity is 1.002. Stat labs reveal…

Physiology of intracranial pressure (ICP) 1. Intracranial pressure dynamics: Intracranial pressure is the pressure of cerbrospinal fluid inside the skull.Normally the cranial vault is a closed box and non compliant structure containing volume of approximately 1500 ml ,comprissing 88% brain matter ,7.5% blood and 4-5 % cerebrospinal fluid . Monrroe kelle hypothesis concludes that any increase in the volume of an intracranial element must be met with an equal compensatory decrease in…

In What is the Safest Sprint Starting Position for American Football Players?, a research article provided by the Journal of Sports Science and Medicine, authors Bonnechere, Beyer, Rooze, and Serge Van Sint, state that the four-point starting position leads to a higher risk of concussion or neck injury in American football players. They also deduce from their research that there is no influence on the learning process effect in varying individuals (i.e. football players and non-players).…

efficient. The causes of hydrocephalus can be acquired or congenital. The congenital causes are Spinal Bifida and Arnold-Chiari malformation. The acquired causes include hemorrhage, meningitis, tumors, cysts and head trauma (Cooper, 2011). The mechanisms in hydrocephalus are the blockage of the flow of the cerebrospinal fluid in the subarachnoid…

An 18-year-old male is brought to the emergency department after suffering from yet another headache. The headaches are abrupt in onset, last for about an hour or so, and then subside for some time before the next episode occurs. The patient has had about three to five episodes per day for the past week and describes the pain as a 10/10 that localizes to either side of his head during an episode but never is felt on both sides at the same time. Associated symptoms during these episodes include a…

They can either be classified as a hemorrhagic stroke or an ischemic stroke (Urden, Stacy & Lough 649). Hemorrhagic strokes, which are also termed as subarachnoid hemorrage, are normally the result of a cerebral aneurysm or arteriovenous malformation. Hypertension, smoking, alcohol and stimulant use can lead to subarachnoid hemorrhage, which are blamed for 13% of strokes (Urden, Stacy & Lough 649). Eighty five percent of strokes are ischemic strokes, where a vascular obstruction, which is…

travel to the brain, called embolic strokes. This type of stroke accounts for 87% of all stroke cases. Hemorrhagic strokes are caused by the bursting of cranial arteries inside the brain, called an intracerebral hemorrhage, or near the surface of the brain, called a subarachnoid hemorrhage. These…

lies within the skull and the spinal cord lies within the vertebral column. Between the soft neutral tissues and the bones that house them are three types of membranous coverings called meninges. Some of the space between these coverings is called subarachnoid space and filled with clear and colorless fluid (cerebrospinal fluid “CSF”). CSF circulates inside the central nervous system through the ventricular part of this system and is finally absorbed into the bloodstream. Thus, the central…
