While there are a number of operating systems on the market today, perhaps the most effective one for online gaming is Windows 7, as it supports high-quality graphics rendering and effective use of system resources.
Answer from Ted Lowenkopf, M.D. , medical director of Providence Stroke Center: Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms. But you really may be asking if a stroke can occur without your realizing, at the time, that it's happening â such as when you are asleep or when the effects are minor. Letâs look at those two scenarios separately.
Diagnostic Imaging: MRI Scan. Another imaging technique used in acute stroke patients is the magnetic resonance imaging or MRI scan. MRI uses magnetic fields to detect a variety of changes in the brain and blood vessels caused by a stroke.One effect of ischemic stroke is the slowing of water movement through the injured brain tissue.T scans are sensitive for detecting hemorrhage and are therefore useful for differentiating hemorrhagic stroke, caused by bleeding in the brain, from ischemic stroke, caused by a blockage of blood flow to the brain.
