What Is The Difference Between Hemorrhage And Embolic Stroke
Bleed vs blockage: Hemorrhagic strokes usually refer to bleeds within the parenchyma or substance of the brain (though subarachnoid bleeding - from an aneurysm or such- is rarely and loosely referred to as a hemorhagic stroke). An ischemic stroke is when brain tissue dies (infarcts) due to a lack of blood flo from a clot or small vessel blockage. It is not uncommon for some bleeding to occur within an infarct. ...Read moreSee 1 more doctor answer
Pathophysiology: Ischemic stroke occurs when an artery to the brain is blocked.A thrombotic stroke occurs when diseased or damaged cerebral arteries become blocked by the formation of a blood clot within the brain. An embolic stroke is also caused by a clot within an artery, but in this case the clot (or emboli) forms somewhere other than in the brain itself. Hemorrhagic stroke is sudden bleed into the brain. ...Read more
Need imaging: Clinically you really can't tell easily which patient has had a hemorrhagic vs an ischemic (because of an embolus) stroke. There are some subtle clinical clues that are beyond what can be discussed here, but the easiest way to tell is a ct of the head. Often hemorrhagic strokes will show up on a non-enhanced ct right away while ischemic strokes often show no changes immediately. ...Read more
A few: A brain attack or stroke maybe from lack of blood flow(ischemic) or a bleed(either clot/embolism or aneurysm) in the brain(intraparenchemal). Both results in death of brain tissue. Other sources of hemorrhage can be in the surrounding tissues such as subdural(around the brain) or subarachnoid(around brain or spinal cord). ...Read more
Stroke: There are 3 major types of stroke: ischemic (meaning loss of circulation) in which an artery supplying the brain becomes blocked (occluded), hemorrhagic (in which a blood vessel bursts and there is free bleeding into the space between the brain and skull (subarachnoid hemorrhoid) or into the brain itself), and embolic (in which a clot drifts downstream in an artery and becomes lodged in the brain) ...Read more
Intensive rehab: Stroke recovery is more related to the size of the stroke, the areas of involvement (motor, speech, vision, etc) than to the exact mechanism of cause. Certain functions of the brain are more plastic (tend to recover) than others, & age is a contributing factor. Recovery tends to be greater in the young than in the elderly. Intensive rehab followed by outpatient rehab provides your best recovery. ...Read moreSee 2 more doctor answers
