There are two types of strokes, which are classified according to the cause of decreased blood flow to a certain region of the brain:
Although they occur differently, both types of stroke cause similar symptoms such as loss of strength or tenderness in an area of the body, difficulty speaking, dizziness, and blurred vision. Therefore, the type of stroke cannot be identified through symptoms, usually confirmed only in the hospital, by an MRI or CT scan.
- In all cases.
- Stroke is always a medical emergency that must be identified as soon as possible and treated in the hospital.
- Since the most important factor in this type of situation is the time between the onset of symptoms and the stabilization of the patient.
- A good way to identify a stroke is to take the SAMU test: see how to take the SAMU test and when to ask for medical help.
The main differences between ischemic and hemorrhagic stroke are explained below:
Ischemic stroke occurs when there is a plaque of fat in one of the brain vessels or when a clot, which has formed elsewhere in the body, can reach the vessels of the brain, causing a blockage that prevents blood from reaching a region of the brain. Brain.
In addition, the causes and form of treatment are other major differences with respect to hemorrhagic stroke:
In addition, it is common for ischemic stroke to be better prognosis than hemorrhagic stroke, as it is generally easier to treat, which reduces the time between early symptoms and patient stabilization, also reducing the risk of sequelae. .
In some cases, a transient ischemic stroke can also occur, in which symptoms last, for the most part, about 1 hour, and then disappear without leaving sequelae. This type can also be known in pre-ictus, so it’s important to go to the emergency room for a checkup and start the right treatment to prevent it from progressing to stroke.
Unlike ischemic stroke, hemorrhagic stroke occurs not by blocking a brain vessel, but by breaking it, preventing blood from continuing to pass through a region of the brain. In addition, during a hemorrhagic stroke, there is also a buildup of blood in or around the brain, which increases brain pressure and further worsens symptoms.
In this type of stroke, the most common causes and form of treatment are:
A hemorrhagic stroke usually has a worse prognosis than ischemic stroke, as it can be harder to control bleeding.
