______ is classified as ischemic or hemorrhagic.
Fight today the cognitive deficits arising from your brain stroke. Stroke is the second most common cause of cognitive impairment and dementia and can significantly affect your attention, memory, planning and other executive functions. Strokes are usually classified into two major categories: hemorrhagic stroke and ischemic stroke. Hemorrhagic strokes are the ones which result from the rupture of a blood vessel while ischemic strokes are those that are caused by interruption of the blood supply. A stroke is when poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. Bleeding may occur due to a ruptured brain aneurysm. The two broad categories of stroke, hemorrhage and ischemia, are diametrically opposite conditions: hemorrhage is characterized by too much blood within the closed cranial cavity, while ischemia is characterized by too little blood to supply an adequate amount of oxygen and nutrients to a part of the brain [1]. More women than men have strokes each year, in part because women live longer. Estimates of the overall annual incidence of stroke in US children are 6.4 per 100,000 children (0 to 15 years), with approximately half being hemorrhagic strokes. 87% of strokes are classified as ischemic. Background and Purpose Recent studies suggest that thrombolytic therapy may be of benefit to patients with acute ischemic stroke. However, the treatment also carries a significant risk of hemorrhagic transformation (HT). The purpose of this study was to select potential contributors to HT.

Selected Answer: Asthma Answers: COPD Hyperventilation Asthma None of the above. Question 5 ________ is classified as ischemic or hemorrhagic. Selected Answer: Stroke 1 out of 1 points 0 out of 1 points 1 out of 1 points 1 out of 1 points 1 out of 1 points. This topic will review the classification of stroke. The clinical diagnosis of stroke subtypes and an overview of stroke evaluation are discussed separately. (See Clinical diagnosis of stroke subtypes and Overview of the evaluation of stroke.) DEFINITIONS. Stroke is classified into two major types: ECASS was a multicenter, placebo-controlled, randomized trial of recombinant tissue plasminogen activator in ischemic stroke, within 6 hours of symptom onset, which enrolled 620 patients. HTs were classified into either hemorrhagic infarction or parenchymal hemorrhage according to their CT scan appearance.
