Hemorrhagic and ischemic strokes are two distinct types of stroke with different underlying causes.
Hemorrhagic Stroke: This type of stroke occurs when a blood vessel in the brain ruptures, leading to bleeding and subsequent damage to brain tissue. The most common types of hemorrhagic stroke are intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH).
Ischemic Stroke: Ischemic stroke, including LVO stroke, is caused by a blockage or obstruction in a blood vessel supplying the brain, leading to reduced blood flow and oxygenation to a specific area of the brain. EEG can help evaluate the effects of ischemic stroke on brain activity, such as detecting abnormal patterns associated with decreased brain function or areas of the brain that are not receiving sufficient blood supply.
To accurately diagnose and differentiate between hemorrhagic and ischemic strokes, medical professionals typically rely on imaging techniques such as computed tomography (CT) scans or magnetic resonance imaging (MRI) scans of the brain. Although EEG might be able to discriminate between an ischemic stroke and a hemorrhagic stroke in the future, more scientific research is required to provide a definite answer to this question.
