1. Causes and symptoms of brain stem stroke.

The brain stem is a constitutive part of the brain, playing a central role in connecting the function of the brain with other parts of the body (cardiovascular, respiratory, ..). A brain stem stroke occurs when there is an interruption in the blood supply to the small arteries located at the back of the neck and brain. The causes of strokes in the brain stem and other areas of the brain are mostly the same.
Brainstem strokes can cause different symptoms and most dangerously can cause weakness, paralysis or even loss of sensation on the side opposite to the damaged brain stem.

A stroke in the brain stem can cause a wide range of symptoms. It can lead to weakness, drooping eyelids, mouth distortion, or loss of sensation on the side of the body opposite the damaged brain stem. Due to the function of controlling the eyes in the brain stem (brain stem, pons), when damaged, the patient may have double vision, can only move one eye, causing asymmetry. In addition, patients often experience symptoms such as dizziness because the balance control function of the brainstem is affected (the vestibular nucleus is located in the pons). A brain stem stroke can also cause dysphagia, difficulty speaking, and hiccups due to a lost or limited ability to move the tongue. This disease can lead to altered consciousness and coma due to the failure of the brain stem to regulate breathing and cardiovascular functions.

2. Brainstem stroke syndrome

Brain stem stroke has the following syndromes:
Ondine's curse syndrome: Causes effects on the ability to breathe Weber's syndrome: Produces weakness on one side of the body with drooping eyelids, loss of ability to breathe. eye movement.

Locked in syndrome: Affects the brain and body parts movement and cognitive ability. Wallenberg's syndrome: Loss of sensation on one side of the face on the same or opposite side of a stroke

3. Brainstem stroke diagnosis

The diagnosis of stroke in the brain stem should be made by a physician knowledgeable and experienced in neurological diseases. Because brain stem strokes often have few obvious signs on CT or MRI because they are so small that they are difficult to see. If symptoms are present, the diagnosis can be made through a thorough clinical examination. It usually takes a few days or weeks for the brainstem stroke to appear on the diagnostic images.

4. Consequences of brain stem stroke

Similar to strokes in other areas of the brain, strokes in the brain stem cause serious consequences, which can be very serious because this place has many important centers (temperature, cardiovascular, respiratory) steam,..). Symptoms can appear and become severe within hours or immediately after recovering from a previous stroke. Careful patient care and monitoring will aid recovery and reduce disability later in life. A brain stem stroke, if not promptly intervened, will cause a coma and rapid respiratory arrest.
To avoid the risk of having a brain stem stroke or any other type of stroke, you should perform early screening at reputable centers - hospitals. Currently, Magnetic Resonance Imaging - MRI/MRA is considered a "golden" tool to screen for brain stroke. MRI is used to check the condition of most organs in the body, especially valuable in detailed imaging of the brain or spinal nerves. Due to the good contrast and resolution, MRI images allow to detect abnormalities hidden behind bone layers that are difficult to recognize with other imaging methods. MRI can give more accurate results than X-ray techniques (except for DSA angiography) in diagnosing brain diseases, cardiovascular diseases, strokes,... Moreover, the process MRI scans do not cause side effects like X-rays or computed tomography (CT) scans.\
