At the hospital, health professionals will ask about your medical history and about the time your symptoms started. There are two types - ischemic and hemorrhagic. Ischemic stroke is the most common type. It is usually caused by a blood clot that blocks or plugs a blood vessel in the brain. This keeps blood from flowing to the brain. Within minutes, brain cells begin to die. Another cause is stenosis, or narrowing of the artery. This can happen because of atherosclerosis , a disease in which plaque builds up inside your arteries.
Transient ischemic attacks TIAs occur when the blood supply to the brain is interrupted briefly. Having a TIA can mean you are at risk for having a more serious stroke. Differentiate ischemic stroke from hypoglycemia, postictal paralysis, hemorrhagic stroke, and migraine. Although clinical differentiation is imprecise, some clues to help differentiate between common types of stroke include symptom progression maximal deficits within minutes of onset with embolic vs sometimes stepwise or slow onset with thrombotic , time of onset day with embolic vs night with thrombotic , and type of deficits eg, specific syndromes and absence of cortical signs with lacunar infarcts.
Test patients for cardiac causes including atrial fibrillation and arterial stenosis, and do blood tests eg, for thrombotic, rheumatic, and other disorders as indicated. To determine eligibility for tPA, use a checklist and, when available consult an expert, either in person or via telemedicine.

Selected Stroke Syndromes Symptoms and Signs. Pure motor hemiparesis.
Primarily clinical evaluation. Headache, coma or stupor, and vomiting are more likely with hemorrhagic stroke. Ischemic Stroke Imaging. A large lucent infarction is seen in the area of brain supplied by the middle cerebral artery. CT scan shows a low-density, well-defined lacunar infarct arrow within the basal ganglia.justsexcave.tk
Cardiac eg, atrial fibrillation, potential structural sources of emboli. A cause cannot be identified for some strokes cryptogenic strokes. Clinical Calculator:.
General stroke treatments. Brain hemorrhage must be excluded by CT. Presentation suggesting subarachnoid hemorrhage even if CT is negative. Arterial puncture at noncompressible site or lumbar puncture in the past 7 days. Use of heparin within 48 h and elevated PTT. In general, do not aggressively reduce BP soon after acute ischemic stroke. Giraldo, MD, MS. Was This Page Helpful? Yes No. Anterior cerebral artery uncommon. Middle cerebral artery common.
