What is Brain Stroke?
A Brain stroke occurs suddenly. A clot shuts off a blood vessel in the brain. Part of the brain will no longer receive oxygen.
This causes symptoms, usually on one side of the body. By acting quickly, serious consequences can be prevented.
How does a Brain stroke occur?
The (inner) wall of the blood vessels is normally smooth so that the blood can flow easily through the vessels.
This wall can be damaged by various causes, such as:
- High blood pressure
The damage causes an inflammatory reaction, which causes the vascular wall to thicken. This inflammatory process is called “Artery Calcification”.
The narrowings that cause a stroke can occur in the neck sagas and small blood vessels in the brain itself.
*Narrowing of the carotid arteries-
A stroke can occur in the carotid arteries. These are large blood vessels through which blood flows to the brain. In these blood vessels, constrictions can occur.
Clots can form in those places. Usually, such a clot does not completely close the carotid artery.
It can shoot through to the brain and clog a smaller blood vessel and cause a stroke.
High blood pressure can damage blood vessels. This makes it easier to cause artery calcification. This can lead to a stroke.
A stroke has lasting consequences. How serious they are depending on the location and size of the infarction.
The most visible consequences such as paralysis or not being able to speak properly are the first to stand out.
But there may also be changes in thinking, doing, or behavior that is less clear at first.
Recognize the signals:
The 3 main signals are a crooked mouth, confused speech, and a paralyzed arm. The signals of a TIA, cerebral infarction and cerebral hemorrhage are the same.
So you don’t know what caused the outage. Therefore, always call 911 immediately!
A crooked mouth, confused speech, or a lame arm.
These are the 3 signs that are most common in stroke. Call 911 immediately if you see anyone with one or more of these signals.
Most common signals
The 3 most common signs of stroke are:
- Crooked mouth: the corner of the mouth suddenly hangs down.
- Confused speech: Someone suddenly talks confused or has difficulty speaking the words.
- Lame arm: Suddenly there is a loss of strength or paralysis of an arm.
Diagnosis For Brain Stroke:
In the hospital, you can determine whether you have a stroke, cerebral hemorrhage, or TIA with a CT or MRI scan of the brain.
That’s important because a TIA or stroke is treated differently than a hemorrhage.
With a CT or MRI scan, you can visualize the brain and find out if someone has a TIA, a stroke, or a brain hemorrhage.
If the neurologist knows what type of stroke it is, the right treatment can start quickly.
1. CT scan
Usually, a CT scan is used in the diagnosis of stroke. It’s available in most hospitals. In a few minutes, the CT scan gives a picture of the brain.
Bleeding and infarctions can be seen shortly after the outbreak.
X-rays are used in a CT scan. The examination does not hurt and can be carried out quickly. You’re lying on a table sliding through some kind of ring.
The device takes a series of X-rays. Each time the recording shifts a few millimeters. From all these figures a 3-dimensional image is made of the brain.
2. MRI scan
The diagnosis of a stroke can also be made with an MRI scan. This scan creates sharp images with a lot of detail.
During the examination, you lie on a table and slide into the narrow tunnel of the scanning device. In a brain scan, this is just the head.
An MRI makes sharp images with a lot of detail. In this way, it becomes clear where the infarction or bleeding is located in the brain.
Also, problems deeper and in the back of the brain are well visible.
In some cases, contrast fluid is first administered to get a better picture of the blood vessels.
This makes it easier to detect constrictions or dilated parts in the veins (aneurysms).
An MRI won’t hurt. The scan works with a strong magnet. This is safe and not dangerous. An MRI takes a little longer than a CT scan.
One disadvantage is that you have to lie very still. The device makes pretty loud noises during the examination.
You get earplugs or headphones with music.
Because of the strong magnet, an MRI is not suitable for people with metal parts in the body.
Treatment For Brain Stroke:
It is important to start proper treatment as soon as possible after a stroke.
Blood flow in the brain needs to be repaired as soon as possible. This can be done by solving or removing the clot in the brain vessel. This reduces the damage.
After a stroke, medication is needed to prevent another infarction. By the following rehabilitation, you work on your recovery.
If the stroke originated from the heart, you will be referred to a cardiologist.
Treating bleeding in the brain
There is often little to do about bleeding in the brain tissue (ICH). It’s just waiting for the bleeding to stop.
However, it is immediately necessary to stop using blood thinners, in order to make the bleeding stop more easily.
You get blood pressure-lowering if your blood pressure is too high.
Rarely is bleeding due to deformity in a brain vessel (Arterio Venous Malformation or AVM).
Treatment is usually not necessary. This only happens if there’s a chance it’s going to bleed again in that place.
Then an operation can take place to remove, stick or irradiate the vascular abnormality.
*Treatment bulge (aneurysm)
A bulge can occur in the blood vessels of the brain. This is called an aneurysm. You can compare that bulge to a balloon.
The further you blow it up, the thinner the wall. The chances of snapping then increase. If that happens, you’ll have a brain hemorrhage.
With this type of bleeding, you need to go directly to a specialized hospital. Here you will be treated quickly, preferably within 24 hours.
This reduces the risk of another haemorrhage.
*Draining cerebrospinal fluid (liquor drainage)
Clipping or coiling is not always possible. The bleeding can increase the pressure in the brain. Then the complaints increase.
This can cause headaches, vomiting, poor vision, or worse failure. To reduce the pressure, it may be possible to drain some fluid from the brain.
This is called liquor drainage. This is done through a hole in the skull.
Rehabilitation after a Brain stroke:
Rehabilitation starts as soon as the situation is stable. This is often already in the hospital. In the first six months, the chances of recovery are highest.
That is why these first months are all about a lot of practice.
Often it only becomes clear after a while whether you have any restrictions left. This can have consequences for your work, household, hobbies, and social activities.
It can be difficult to accept if this is no longer possible completely. For yourself, but also the people around you, such as your family and friends.
