A high score corresponds to a greater risk of stroke, while a low score corresponds to a lower risk of stroke. The CHADS 2 score is simple and has been validated by many studies. [ 2 ] In clinical use, the CHADS 2 score (pronounced "chads two") has been superseded by the CHA 2 DS 2 -VASc score ("chads vasc" [ 3 ] ), which gives a better ...
Current guidelines recommend antiplatelet therapy for patients with non-cardioembolic ischemic stroke. [8] [9] [10] However, it is widely believed that there is a substantial overlap between ESUS and cardioembolic stroke, clinical trials have assessed the benefit of anticoagulation versus antiplatelet agents for preventing recurrent stroke.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .

Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes: Complications: Coma, persistent vegetative state, cardiac arrest (when bleeding is in the brain stem or is severe), death: Types
The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS), is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke and aid planning post-acute care disposition, though was intended to assess differences in interventions in clinical trials. The NIHSS was designed for the National ...
Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
