Cerebellar Stroke

Cerebellar Stroke Symptoms: Ipso facto

The following are some of the common symptoms associated with cerebellar stroke. These symptoms may persist for days or weeks after the stroke.

Dizziness (vertigo)

Blurred vision (mydriasis)

Difficulty concentrating (anterograde amnesia)

Confusion (parietal lobe dysfunction)

 In addition to these symptoms, there are other signs and symptoms which may occur during the course of a cerebellar stroke. They include:

Tremors (ataxia)

Nausea/vomiting

Diarrhea/constipation (diabetic ketoacidosis)

 These symptoms are usually transient and resolve within a few hours to a day. However, they may persist for months or even years.

If left untreated, they can lead to death.

The information above is about symptoms that are related to cerebellar stroke.

Cerebellar Stroke Syndrome: A Closer Look

A stroke happens when the blood supply to a certain part of the brain is cut off (due to blockage or rupture of blood vessels). Neurons in this area begin to die due to an inadequate supply of oxygen and nutrients.

The death of these cells results in permanent damage to the brain.

It is important to understand the different kinds of strokes and their causes and effects. This will help you recognize the symptoms early enough for treatment and also to take steps to prevent a stroke.

The two major types of strokes are:

Ischemic stroke (also known as a blockage stroke) – These account for about 80% of all strokes. A blood vessel (artery) leading to the brain gets blocked or ruptures.

The symptoms are caused by the part of the brain not receiving any blood and dying. This is known as an infarct.

Hemorrhagic stroke (also known as a bleed stroke) – These account for about 20% of all strokes. A person usually has an aneurysm (a weak area in the artery wall) or a congenital hemorrhage (an abnormal, weak, or faulty blood vessel).

Bleeding into the brain then occurs. The blood then presses on the brain and causes damage. The symptoms and effects are the same as for an infarct.

The effects of a stroke depend on the size of the area of the brain that is damaged, whether it is a blockage or a bleed, and which parts of the brain are involved.

There are various kinds of strokes and their effects, including:

Ischemic stroke (blockage) – The most common kind of stroke is called an ischemic stroke. This accounts for about 80% of all strokes.

It occurs when an artery leading to the brain becomes blocked or ruptures. Blood cells build up and form a clot (thrombus) that partially or completely blocks the flow of blood to the brain. The resulting lack of oxygen and nutrients leads to cell death (infarction).

Transient Ischemic Attack (TIA) – A transient ischemic attack is like a mini-stroke. The symptoms are similar but last only a few minutes to a few hours.

They often disappear before medical help can be received. A brain scan will show signs of ischemia but no permanent damage has occurred. Treatment is the same as for a minor stroke and blood thinners may or may not be used.
