A stroke occurs when an artery supplying blood to the brain becomes completely blocked, usually by a blood clot. If clots are to blame, then they are known as emboli.
When a clot blocks the blood supply to the brain, it becomes known as a stroke.
Strokes can have a number of different causes. Some examples include:
- A blood vessel ruptures
- A tumour in the brain
- A blood clot in the brain
- A blood clot in the heart
- A bleeding in the brain
- A hemorrhage
A stroke can also be triggered by a buildup of fluid inside the brain, known as a subarachnoid hemorrhage (SAH).
Some people who suffer from an SAH experience a sudden, intense headache that quickly evolves into a full-fledged migraine.
Some people notice a sudden aura before the stroke occurs, which causes them to experience a strange feeling before the stroke occurs.
If you have experienced these symptoms, you should be aware of the possibility that you may be suffering from a stroke.
The symptoms you experience and the sudden aura you have before a stroke can be the result of the same condition that is causing a stroke.
However, it is important that you get medical attention as soon as possible if you experience any of the following:
- A severe headache
- A sudden, intense migraine
- Severe nausea
- Numbness or weakness
- Sudden vision loss
If you experience any of these symptoms or any of the symptoms listed above, contact your doctor immediately.
If you do indeed have a stroke, your doctor will most likely send you for an MRI scan. This is to check for signs of a blood clot.
The scan will look for any evidence that the stroke was caused by a blockage in the artery.
To diagnose a stroke, your doctor will also want to know what time of day you had the stroke. If you had any of the symptoms listed above, such as numbness or vision loss, then you should seek medical attention right away.
If your doctor suspects your stroke was caused by a blood clot, they will likely want to perform a lumbar puncture (spinal tap). This is a procedure that involves inserting a needle into the lower back.
During the procedure, your doctor will draw out blood for analysis. It will be sent to a laboratory, where the doctor can check for any blood clots.
If your doctor suspects you have an embolic stroke, they will want to perform other tests. These include an echocardiogram and an electroencephalogram (EEG).
An echocardiogram is a test that uses sound waves to look at the structure of your heart. It is used to look at the size, shape, and function of your heart.
An EEG is a test that uses electrodes to look at the electrical activity in your brain. It is used to detect any abnormalities in the electrical activity of your brain.
Once your doctor has confirmed that you have had a stroke, they will also want to check for any other stroke-related conditions. This may include:
- Blood clots
- A blood vessel disorder
- A brain tumor
- An infection
If you have had any of these conditions, you will be advised to have regular check-ups to monitor their progress.
If you have a history of these conditions, you should make sure you attend regular check-ups.
What are the treatment options for a stroke?
There are a number of different treatment options for stroke.
Treatment may depend on the type of stroke you have. Some examples include:
- A middle cerebral artery stroke
- A posterior circulation stroke
- A lacunar stroke
- An intracerebral hemorrhage
- An SAH
- An embolic stroke
Treatment for a stroke depends on the type and severity of the stroke. The type and severity of the stroke will determine the treatment options.
Treatments for a stroke may include:
- A combination of the two
It is important to realize that not all stroke treatments are the same. For instance, surgery will only be an option for a small group of people.
When comparing different options, it is important to look at the different benefits and risks associated with each.
Treatments may include:
- Physical therapy
- Speech therapy
- Cognitive training
It is important to remember that stroke is a very serious condition, and it can cause permanent damage.
You should seek medical attention as soon as possible if you experience any of the following:
- A severe, sudden headache
- A sudden, intense headache
- Numbness or paralysis
- Loss of strength
- Loss of consciousness
- A sudden vision loss
If you experience any of these symptoms, contact your doctor right away.
What is the outlook for someone with a stroke?
In general, the outlook after a stroke is positive. However, some stroke survivors experience permanent damage.
If you have had a stroke, it is important to seek medical attention as soon as possible. This will help your recovery and may help minimize the damage that is caused by the stroke.
Once you have had a stroke, there is no cure. However, if you seek medical attention as soon as possible, you can minimize the damage and potentially improve your quality of life.
It may take some time to recover from a stroke. However, you can do so and return to your previous level of functioning.
Prevention is key
Stroke is preventable. There are steps you can take to reduce your risk of stroke.
It is important to be aware of your risk factors and take steps to reduce them.
If you experience any signs of a stroke, you should seek medical attention.
