[61], Stroke is diagnosed through several techniques: a neurological examination (such as the NIHSS), CT scans (most often without contrast enhancements) or MRI scans, Doppler ultrasound, and arteriography. [149] In those with findings of savable tissue on medical imaging between 4.5 hours and 9 hours or who wake up with a stroke, alteplase results in some benefit. In thrombotic stroke, a thrombus[39] (blood clot) usually forms around atherosclerotic plaques. [81] Smoking just one cigarette per day increases the risk more than 30%. The word stroke was used as a synonym for apoplectic seizure as early as 1599,[217] and is a fairly literal translation of the Greek term. [68] Primary prevention is less effective than secondary prevention (as judged by the number needed to treat to prevent one stroke per year). [173], Treatment of spasticity related to stroke often involves early mobilizations, commonly performed by a physiotherapist, combined with elongation of spastic muscles and sustained stretching through various different positions. [68] Recent guidelines detail the evidence for primary prevention in stroke. With the current treatment and diagnosis options available, it is of particular importance to determine whether there is a peripheral source of emboli. Giving thrombolytics (clot-busting) in such cases causes intracerebral bleeding 1 to 2% of the time, which is less than that of people with strokes. Since blood vessels in the brain are now blocked, the brain becomes low in energy, and thus it resorts to using anaerobic metabolism within the region of brain tissue affected by ischemia. [128][129], A number of specific recommendations have been made for women including taking aspirin after the 11th week of pregnancy if there is a history of previous chronic high blood pressure and taking blood pressure medications during pregnancy if the blood pressure is greater than 150 mmHg systolic or greater than 100 mmHg diastolic. However, stroke cuts off the supply of oxygen and glucose which powers the ion pumps maintaining these gradients. [187] Constraint‐induced movement therapy (CIMT), mental practice, mirror therapy, interventions for sensory impairment, virtual reality and a relatively high dose of repetitive task practice may be effective in improving upper limb function. These programs are tailored to the target audience, and led by someone trained and expert in stroke and its consequences (most commonly professionals, but also stroke survivors and peers). And in some of these persons, strokes have been found which were then treated with thrombolytic medication. [220][221][222] Cerebrovascular insult may be used interchangeably. [180] Reduced fitness can reduce capacity for rehabilitation as well as general health. Most forms of stroke are not associated with a headache, apart from subarachnoid hemorrhage and cerebral venous thrombosis and occasionally intracerebral hemorrhage. Swallowing therapy has mixed results as of 2018. Almost half of all acute ischemic strokes are due to large vessel occlusion (LVO). Acute ischemic stroke occurs when blood flow through a brain artery is blocked by a clot, a mass of thickened blood. A scoring system called ROSIER (recognition of stroke in the emergency room) is recommended for this purpose; it is based on features from the medical history and physical examination.[35][37].
