If their last known normal is within 4.5 hours of presentation, they are within the window for receiving IV tissue plasminogen activator (TPA) if it is within 24 hours, they are within the window for neurosurgical intervention. The reason this is so important is that it determines what options are available for their management. The most important component to obtain in the history of these patients is their last known normal, which is when they were last seen or last felt that they were at their baseline. This is done because there is a specific protocol that has to be followed to quickly obtain the most important components of the history, perform the pertinent parts of the physical exam, and get the emergent laboratory studies and relevant imaging.

When patients present with under 24 hours of neurological symptoms, such as weakness, dizziness, numbness, issues with speech, or visual changes, they are managed in the form of a stroke alert or a code stroke. This is likely related to the advancements made in secondary stroke prevention in higher-income countries. In addition, mortality due to stroke has increased in middle and low-income countries. Over the last few decades, stroke occurrence and mortality have overall decreased in the United States and other high-income countries, but no change in frequency has been observed in middle or low-income countries. The risk of stroke is higher in men than women when young and middle-aged, but overall, women have a higher risk of stroke than men over the course of a lifetime, with the risk for women being 20% to 21% versus 14% to 17% in men. The risk of stroke is also higher in Blacks and Hispanics than Whites. Approximately 85% of these are ischemic strokes, and over half of all ischemic strokes occur in MCA territory. The overall prevalence of stroke in the U.S. Stroke is the fifth leading cause of death in the United States and the second leading cause of death worldwide. In both of these cases, clots can travel from the heart through the left ventricle into the aorta and lodge in the internal carotid artery (ICA) or its branches, most frequently the MCA. The smaller deeper vessels that are the culprits of lacunar infarcts, such as the lenticulostriate arteries, are more often affected by hypertension and diabetes than by thromboses. Cardioembolic strokes can occur in the case of atrial fibrillation or, in younger individuals, a patent foramen ovale, particularly in the setting of deep vein thromboses. In the case of atherosclerotic disease, severe stenosis or thrombosis can be caused by cholesterol plaques, which can cause occlusions of vasculature or stenosis of vessels, blocking blood flow and leading to cerebral ischemia. However, ischemic stroke can also, at times, be due to more specific causes such as vasculitis, dissections, or genetic disorders. Ischemic stroke is frequently broken into several etiological categories, including atherosclerotic, cardioembolic, lacunar, and cryptogenic. Less frequently, hemorrhagic strokes can also be due to angiopathies, which can be diagnosed with a cerebral angiogram. The etiology of hemorrhagic stroke is most frequently hypertension, especially in developing countries where the burden of hypertension is unknown due to infrequent screening and diagnosis. However, hyperlipidemia, physical inactivity, diabetes, and cardiac causes such as cardiomyopathy, heart failure, and atrial fibrillation, are risk factors for ischemic stroke but not hemorrhagic stroke. Modifiable risk factors, including hypertension, smoking, obesity, alcohol consumption, and diet all contribute to both ischemic and hemorrhagic stroke. The risk increases as you get older the risk is higher in men at a younger age, but the risk of death is higher overall in women and the risk is significantly greater in African Americans, and slightly higher in Hispanics and Native Americans as well, compared to whites. The nonmodifiable risk factors of each include age, sex, race, and genetics. There are multiple risk factors for strokes, which can be divided into modifiable and nonmodifiable categories-many of the causes of hemorrhagic and ischemic stroke overlap.
