Spinal strokes occur due to blockages in the spinal cord’s blood supply. Without an adequate blood supply, the spinal cord will not receive the oxygen and nutrients required to function.

Medical professionals refer to spinal strokes as spinal cord infarctions. Any disruption to the blood supply can damage the spinal cord and prevent it from communicating with the rest of the body. This can result in severe back pain, limb weakness, and a loss of nerve sensation.

In this article, learn about the symptoms, causes, treatment, and recovery.

The spine uses nerve impulses to communicate with different parts of the body. In severe cases of spinal stroke, the lack of communication can cause paralysis and may be life-threatening.

Unlike other strokes, spinal strokes do not typically disrupt the blood supply to the brain. However, they do have similar causes. Spinal strokes are rare, accounting for just 0.3-1% of all strokes.

The majority of spinal strokes are ischemic, meaning that they result from blood clots in blood vessels.

Less commonly, bleeding from ruptured blood vessels can cause a spinal stroke. This type of stroke is called a hemorrhagic stroke.

The symptoms of spinal strokes may vary from person to person, depending on the location of the stroke in the spine. The severity of the damage and speed of treatment will also influence symptoms.

Symptoms include:

In severe cases, a spinal stroke can cause death.

The majority of spinal strokes occur due to changes in the shape of blood vessels. For example, blood vessel walls may thicken, which will cause the vessels to narrow. This can sometimes happen as a natural consequence of aging.

However, specific factors increase the likelihood of this happening, including:

All of these factors put additional strain on the circulatory system, increasing the chance of damaged or dysfunctional blood vessels.

For example, high blood pressure can damage and weaken blood vessels, making them more likely to rupture and bleed. This can cause a stroke.

In some cases, problems with the heart or the aorta can cause spinal strokes. These problems include severely low blood pressure or a lack of blood flow through the aorta. In rare cases, tangled blood vessels can also cause a spinal stroke.

Anyone experiencing a spinal stroke needs immediate medical attention and prompt diagnosis.

A doctor will look for common indicators of a problem with the spinal cord, such as weakness in the legs. If a doctor suspects a spinal stroke, an MRI is usually necessary to rule out other conditions that could damage the spinal cord.

An MRI can also help to confirm the presence and location of a blockage or bleed.

Treatment for a spinal stroke will depend on the underlying cause. In cases of ischemic spinal stroke, a doctor will give the person medications to thin the blood and reduce the risk of blood clots. These are known as antiplatelet and anticoagulant drugs. They include common drugs, such as aspirin.

Medication may also be necessary to manage a person’s symptoms, as well as their risk factors for another stroke.

For example, for people with high blood pressure or high cholesterol, a doctor may prescribe medication to control these factors.

A person with paralysis may benefit from occupational and physical therapy, which can make it possible to regain some range of motion.

If a person loses bladder control, they may need a urinary catheter.

Spinal strokes can have severe, long-term complications, depending on the extent of the damage and the location of the stroke.

Complications of a spinal stroke can include:

It is possible to make a partial or even full recovery from a spinal stroke. In addition, people typically have better recovery outcomes from spinal cord strokes than strokes that affect the brain.

The degree of recovery depends on the cause and location of the stroke, the extent of the damage, the success of the treatment, and the individual’s overall health status.

However, many people will experience lasting complications after a spinal stroke and may require long-term treatment or have to implement lifestyle changes.

For most people, certain lifestyle changes are essential to reduce risk factors and improve the chances of a full recovery.

These could include:

Many people make a full recovery from a spinal stroke, but this can take months or even years. Paralysis following a spinal stroke may last for a few weeks or may be permanent.

People can reach out to support groups and consider seeing a therapist to help their recovery and reduce stress.

Spinal cord strokes, or infarctions, occur due to disruptions in blood supply to the spinal cord. They are often the result of artery blockages or the thickening of artery walls.

Symptoms include back pain, muscle weakness, and in severe cases, paralysis.

Treatment for spinal cord strokes typically involves treating their underlying cause. Full and partial recoveries are possible, and a person’s outlook will vary depending on the extent of damage incurred and the pace of treatment.
