Strokes are the third leading cause of death in the United States and a significant source of neurological and physical debilitation.

Some stroke survivors fully recover, while others are left unable to talk, walk, or care for themselves.

This is a major cause of a decreased quality of life.

There are few treatments available after someone has suffered from a stroke, but recent studies have shown that CBD oil may offer benefits to people suffering from this condition.

Here, we discuss how CBD can help stroke victims and offer a few of the best CBD oils on the market for people suffering from the debilitating side effects of a stroke.

Can CBD Oil Support Stroke Patients?

In recent years, the public and academic interest in cannabis and its chief non-psychoactive cannabinoid, CBD, has grown substantially.

There are thousands of research studies published on the compound this year alone.

Many of these studies involve neurological function, and we are starting to develop a better understanding of how the compound works in the brain, and how we can use it to support people suffering from conditions such as strokes.

One of the main findings involves the protective effect CBD offers the brain.

The benefits of CBD oil for strokes include:

  • Protects the brain cells
  • Resists oxidative damage in the brain
  • Improves blood flow to the brain
  • Reduces high blood pressure
  • Reduces glutamate toxicity
  • Promotes faster recovery of damaged neurons after a stroke

1. Protects Brain Cells

Damaged neurons are the cause of the side effects of a stroke.

When the neurons are unable to get the oxygen and nutrients they need, they become damaged and may die off, leaving us with lasting neurological damage.

One of the critical areas of focus when supporting stroke patients is to work on the overall health of the neurons.

CBD is especially useful for neuron health.

CBD improves neuron health by supporting something called calcium ion handling (necessary for nerves to send electrical impulses), and neuron metabolism (how the neurons generate energy to survive).

We’ll discuss exactly how this works in more detail below.

2. Resists Oxidative Damage

All of our cells need oxygen and a source of energy to survive.

As soon as blood flow is cut off from a cell, it becomes sick.

In the absence of oxygen, the cell produces toxic metabolic byproducts as it tries to continue doing its job. If these toxic compounds build up for too long (2-3 minutes), they can cause the cells to die.

These metabolic compounds are often referred to as free radicals. They’re unstable compounds that tear apart our cell structures as they try to stabilize themselves.

Our body uses something called antioxidants to take the hit for us, stabilizing these free radical compounds and preventing them from causing damage to the body.

Oxidative damage is the key feature for lasting stroke damage and is one of the main areas of treatment.

CBD and full-spectrum hemp extracts have high concentrations of antioxidants that help protect neurons from damage when toxic compounds build up. 

3. Improves Blood Flow to the Brain

Since ischemic strokes are caused by poor blood flow, it makes perfect sense to improve blood flow to the brain to prevent further damage.

CBD improves blood flow to the brain through its terpene content.

Terpenes are the volatile compounds contained in plants, responsible for the flavor and aroma.

Terpenes also have a wide range of therapeutic benefits, including improved cerebral blood flow.

Some examples of cannabis terpenes with proven benefits regarding cerebral blood flow include:

  • Eucalyptol [6]
  • Caryophyllene oxide [7]
  • Borneol [8]

Even CBD is proven to increase cerebral blood flow through its modulating effects on serotonin receptors, which play a critical role in regulating the amount of blood that enters the brain [9].

In order to get the most benefit on cerebral blood flow, it’s important to note that the CBD oil used in clinical trials are full-spectrum extracts containing all these critical terpenes.

CBD isolates aren’t likely to have any of these terpenes and therefore won’t provide the same level of benefit.

4. Reduces High Blood Pressure

High blood pressure is one of the primary causes of stroke.

Consistently high blood pressure can dramatically increase the chances of having another stroke. For this reason, many doctors choose to treat blood pressure as one of the primary preventions for another stroke.

A randomized clinical trial found that a 600 mg dose of CBD was able to reduce resting blood pressure scores by 6 mmHg [10].

5. Reduces Glutamate Toxicity

CBD was shown to protect against N-methyl-D-aspartate and beta-amyloid peptide toxicity [1].

What does this mean?

It suggests that CBD can protect the neurons from age-related damage and has the potential to prevent strokes brought on by age-related cognitive decline.

Another study looked at the effects of ischemic injury (lack of oxygen) in gerbils treated with CBD. All of the animals given CBD showed significantly less permanent damage than animals not given CBD [2].

This highlights the potent neuroprotective effect offered by CBD in relation to stroke damage.

CBD was found in a number of studies to offer antioxidant support, including hydroperoxide toxicity in the neurons [3].

What Is A Stroke?

A stroke is a result of blocked blood flow to various parts of the brain. When this happens, essential nutrients and oxygen can’t make it to the delicate cells of the brain, which potentially results in severe damage.

If this happens for just a few minutes, the cells in the brain start to die and can cause long-term problems. This condition is a medical emergency and often fatal.

If blood flow is restored fast enough, you can avoid lasting damage.

However, it can take several months for a patient to recover from a stroke.

There Are 2 Types of Strokes:

1. Ischemic Stroke

An ischemic stroke is the most common form of a stroke and is the most survivable.

An ischemic stroke occurs when blood flow is cut off from regions in the brain. It can happen if a blood or cholesterol clot gets lodged in the cerebral arteries feeding the brain. Once the artery is blocked, blood cannot flow to the region it supplies.

Within about two or three minutes, the neurons suffocate and die. This cell death is permanent; neurons do not grow back.

The side effects may be different depending on which region of the brain is affected.

As an example, if regions of the brain associated with speech are affected, you may lose your ability to communicate.

Causes of Ischemic Stroke:

2. Hemorrhagic Stroke

Hemorrhagic strokes are much more serious.

This type of stroke involves a burst blood vessel in the brain. These strokes are almost always fatal.

As blood leaks out from the burst artery, it isn’t able to reach the cells it feeds, causing them to die.

Causes of a Hemorrhagic Stroke:

  • Smoking
  • High blood pressure
  • Blood-thinner medications
  • Aneurysms (weak spots in arterial walls)

Signs & Symptoms Of A Stroke

There are a few key symptoms and side effects of a stroke that are important to keep in mind.

Symptoms During The Stroke:

While a stroke is happening, some key indicators tend to appear:

  • Difficulty speaking
  • Difficulty understanding people
  • Weakness, usually on one side of the body
  • Severe headaches
  • Vision disturbances
  • Paralysis in the face, arms, or legs
  • Difficulty walking

Symptoms After The Stroke:

There may be some lasting side effects after the stroke.

Many people report the following side effects after a stroke:

  • Weakness on one side of the body
  • Nerve pain
  • Difficulty swallowing
  • Difficulty speaking
  • Numbness or tingling sensations in the limbs
  • Memory loss
  • Changes in behavior and self-care ability
  • Depression

Care and Treatment After The Stroke:

Treatment depends on the severity and cause of the stroke. The chances for another stroke increase significantly, so reducing this risk is a necessary part of post-care.

  • Physical, occupational, and speech therapy
  • Healthy lifestyle changes
  • Medications to control underlying causes of strokes such as high blood pressure, high cholesterol, and diabetes
  • Surgery

What Are The Best Products For Strokes?

CBD offers a few excellent benefits that may reduce side effects after a stroke.

It’s also useful for reducing the chances of having another stroke in the future and protects against a lot of the damage that occurs during a stroke event. However, it’s important to talk to your doctor first, since CBD can interact with some medications.

The best CBD oils for treating stroke are products with a high CBD concentration, small amounts of THC, and a full-spectrum of terpenes and other phytochemicals.

CBD isolates should be avoided in people who have recently suffered from a stroke because they won’t be nearly as effective as full-spectrum options.

We recommend using full-spectrum high-quality hemp oil.

These products are made using high-quality ingredients free from pesticides, and contaminants. Unnecessary chemical compounds such as solvents or pesticides may aggravate stroke symptoms and are therefore best to avoid.

Measuring Neurological Damage After A Stroke

There are two markers scientists use to determine neuron health:

  1. Calcium ion handling
  2. Metabolic activity

These two metrics are reliable measures for the health of the nervous system.

The first one, calcium ion handling, refers to how well the neurons can move calcium atoms in and out of the neuron. This function allows neurons to pass electrical signals down from one end of the nerve to the other.

When calcium ions aren’t functioning as well as they should, the nerves are unable to send signals to other parts of the brain as easily. This is a red flag indicating the neurons are starting to degrade.

This is a key issue with people after surviving a stroke [5].

CBD offers direct benefits to calcium handling in neurons and controls the rate of cell death (apoptosis) by restoring damaged neurons to push them back to a better state of health [4].

The second measurement of neuron health, metabolic activity, is also a key issue that may develop following a stroke. After brain scans of people following a stroke, it’s common to see areas of the brain with low or completely absent metabolic activity [6].

It’s the absence of metabolic activity that causes many side effects of the stroke, such as weakness, fatigue, confusion, or loss of bladder/bowel control.

Using CBD for Strokes

Although more research is needed to better understand precisely how CBD oil benefits stroke victims, there’s a lot of evidence to support its potential as a preventative and post-event treatment.

Most of the studies quoted in this article suggest using about 400 – 600 mg of CBD equivalent each day.

This is best done with a full-spectrum CBD oil to get the advantages of the other cannabinoids and terpenes.

It’s also important to mention that in order to get the most out of your CBD oil, you need to take it regularly for long periods. Most people who take CBD oil after a stroke take it every day without fail.

The benefits it’s going to provide are diverse. Some are felt immediately; others require a few weeks of regular treatment to start to appear.

It’s also recommended that you quit smoking, take measures to lower your stress, and add gentle exercise into your daily routine to further improve your odds of recovering or avoiding future strokes.
