Approximately one-third of epilepsy patients do not become seizure free with antiseizure medications (ASMs). This treatment gap motivates research for new therapeutic options such as cannabidiol (CBD). CBD differs from other cannabis derivatives because of its consistent efficacy and lack of a psychoactive effect. CBD can be recommended as adjunctive therapy in patients with Dravet and Lennox-Gastaut syndromes. The most common adverse effects (AEs) are drowsiness, reduced appetite, diarrhea and vomiting. Transaminase elevation is the most common AE that leads to CBD discontinuation. Coadministration with valproate may increase the risk of hepatotoxicity. The combination of CBD and clobazam may increase both the effectiveness and the risk of AEs associated with these drugs. The most striking gaps in knowledge are the efficacy and optimal dose of cannabidiol for adults with focal epilepsies, thelong-term safety of CBD use and strategies to improve access to CBD for people living with epilepsy. Children with drug-resistant epilepsy may find relief with the help of medical cannabis oil that contains both CBD and lose dose THC. The oil, which contains 95% CBD and 5% THC, can reduce or prevent epileptic seizures in those with epileptic encephalopathy. CBD has been shown to reduce the severity & frequency of seizures.

Introduction

Epilepsy can be a therapeutic challenge. Despite the growing number of antiseizure medications (ASMs), approximately one third of patients with epilepsy have persistent seizures (1). Surgical treatment, although still underused, may be an alternative in up to 25% of these cases (2). Therefore, many patients are not seizure free. This treatment gap motivates research on new ASMs, such as cannabidiol (CBD).

The medical use of marijuana has gained considerable interest in the press in the last two decades. Three reasons for this are (a) the appeal of being a “natural” alternative treatment (3); (b) the discovery of a complex cell-signaling system responsive to cannabis, the endocannabinoid system (4); and (c) prominent public cases, such as Charlotte Figi in the United States (5).

Cochrane and American Academy of Neurology reviews determined that there was no scientific evidence to support the use of cannabis for epilepsy in 2014 (6, 7). At that time, there were only four placebo-controlled studies on cannabinoid use in epilepsy (8–11). All studies show inadequate power and methodological problems, but despite this, there has been an increasing use of CBD for the treatment of epilepsy (12).

Cannabinoids are obtained from different species of cannabis. Tetrahydrocannabinol (THC) and cannabidiol (CBD) are two of the most prominent cannabinoids found in the Cannabis plant (3). THC is responsible for the psychoactive effects of marijuana, but studies on its effects on epilepsy have shown conflicting results (13–16). THC binds to type 1 cannabinoid receptors (CB1) present in the basal ganglia, cerebellum, hippocampus, hypothalamus, and limbic system. Anandamide and 2-arachidonoylglycerol are endogenous cannabinoid agents that act on presynaptic CB1 and cause a reduction in excitatory activity. As THC is a partial agonist, this could explain the proconvulsant effect.

CBD is a cannabinoid that lacks psychoactive effects. It has a more consistent antiepileptic efficacy than THC (17, 18). CBD does not activate cannabinoid receptors. It does, however, interact with several other signaling systems. Transient receptor potential vanilloid type 1 (TRPV1)-mediated signaling may be the most relevant pathway in the anticonvulsant effect of CBD (19–21).

Evidence on Effectiveness

In 2016, Dr. Orrin Devinsky presented an open-label study with 214 pharmacoresistant child-onset epilepsy patients who received CBD. Dravet (20%) and Lennox-Gastaut (19%) syndromes were the most frequent causes. The initial dose of 5 mg/kg/day was increased up to a maximum dose of 50 mg/kg/day if tolerated. The median monthly frequency of motor seizures was 30.0 at baseline and was reduced to 15.8 over the 12-week treatment period (22).

Another open-label study was performed in patients with pharmacoresistant epilepsy with tuberous sclerosis who received CBD. The initial dose of 5 mg/kg/day was increased by 5 mg/kg/day every week up to a maximum dose of 50 mg/kg/day if tolerated. The median reduction in total weekly seizure frequency was 48.8% after 3 months of treatment (23).

In 2017, the first randomized, double-blinded, placebo-controlled study evaluating high-purity CBD in patients with Dravet syndrome was published (24). The intervention group received a highly pure 100 mg/ml CBD solution. The dose was increased up to 20 mg/kg. The percentage of patients who had at least a 50% reduction in convulsive-seizure frequency was 43% after a 14-week treatment period with CBD. The overall conditions improved by at least one category on the Caregiver Global Impression of Change scale for 62% of patients in the CBD group. Three patients in the CBD group were seizure free. There was no significant reduction in nonconvulsive seizures.

In 2018, a randomized, double-blind, placebo-controlled study was published on patients with Lennox-Gastaut syndrome who used CBD (25). The patients had two or more drop seizures per week and a mean age of 16 years. Favorable outcomes were found in the 10 and 20 mg/kg CBD groups during the treatment period with a median percentage reduction from baseline in the frequency of drop seizures of 37.2 and 41.9% in the 10 and 20 mg/kg CBD groups, respectively.

Secondary outcomes were also significant. Thirty-six percent and 39% of patients had at least a 50% reduction from their baseline in drop-seizure frequency in the CBD groups compared with 14% in the placebo group. Furthermore, compared with the placebo group, a greater percentage of patients had at least a 75% reduction from baseline in drop-seizure frequency (11 and 25% in the CBD groups, 3% with placebo). Some patients became free from drop seizures during the entire maintenance phase in the CBD groups (4% and 7%, 1% in the placebo group).

The estimated median difference in reduction from baseline in the frequency of all seizures was 19.5 (p = 0.002) and 18.8 (p = 0.009) percentage points in the 10 and 20 mg CBD groups, respectively. Additionally, an improvement from baseline in overall condition according to the Patient or Caregiver Global Impression of Change at the last visit was reported in 66 and 57% of 10 and 20 mg CBD-treated patients, respectively, compared to 44% in the placebo group with an odds ratio of 2.57 (p = 0.002) for the 10-mg cannabidiol group vs. the placebo group and 1.83 (p = 0.04) for the 20 mg cannabidiol group.

Another randomized, double-blind, placebo-controlled phase 3 trial investigated the efficacy of CBD as an add-on therapy for drop seizures in patients with treatment-resistant Lennox-Gastaut syndrome. The results confirmed the efficacy of CBD with a median percentage reduction in monthly drop seizure frequency from a baseline of 43.9% in patients treated with 20 mg/kg of CBD compared to 21.8% in the placebo group. Other secondary outcomes were positive, including a greater proportion of patients experiencing a reduction of ≥75% seizures during the treatment period (20% CBD vs. 8% on placebo; p = 0.0273) (26).

A systematic review identified six randomized controlled studies (27). The average age of the participants was 16.1 years (0.5–55 years). At a dose of 20 mg/kg/day, the number needed to treat to one person experiencing 50%+ seizure reduction was 8. CBD was more effective than placebo at achieving complete seizure freedom. In 14 observational studies, 8.5% of patients were seizure free (95% CI, 3.8–14.5%).

Another recent systematic review (28) evaluated the role of concomitant clobazam (CLB) use on the efficacy of CBD in patients with Dravet syndrome and Lennox-Gastaut syndrome and enrolled 714 participants in four trials (429 treated with CBD, 240 with taking concomitant CLB). The percentages of patients not taking CLB who had at least a 50% reduction in seizure frequency during the treatment period were 29.1% with CBD and 15.7% in the placebo group (RR 1.80, p = 0.015); among patients receiving CLB, a 50% reduction in seizure frequency was achieved by 52.9 and 27.8% in the CBD and placebo groups, respectively (RR 1.85, p < 0.001). This study suggests that despite the drug–drug interactions that occur between CBD and CLB, adjunctive treatment with CBD can reduce seizures independent of concomitant CLB, reinforcing that CBD has intrinsic antiseizure activity (28).

Available data indicate that patients cotreated with CBD and CLB have higher response rates, highlighting that both pharmacodynamic and pharmacokinetic interactions may contribute to the efficacy of this combination (29).

Therefore, CBD is effective as an adjunctive therapy in the treatment of drug-resistant childhood-onset epilepsy. Nevertheless, current evidence is restricted to rare and severe epileptic syndromes. A summary of CBD effectiveness can be seen in Table 1 and Figure 1 (12).

Cannabis dosage studied to reduce seizures in children with severe epilepsy

Summary: Children with drug-resistant epilepsy may find relief with the help of medical cannabis oil that contains both CBD and lose dose THC. The oil, which contains 95% CBD and 5% THC, can reduce or prevent epileptic seizures in those with epileptic encephalopathy.

Source: University of Saskatchewan

Medicinal cannabis oil containing both cannabidiol (CBD) and a small amount of THC can reduce or end seizures in children with severe, drug-resistant epilepsy, a study by the University of Saskatchewan (USask), Canada has found.

Children with severe epilepsy also experienced improvements in their quality of life after taking low doses of the medicinal cannabis oil, according to research published in Frontiers in Neurology.

The study tested the effects of medicinal cannabis oil with 95 percent CBD, a chemical which does not create a high, and 5 percent THC, a substance which can be intoxicating in large enough doses.

Studying an evidence-based scientifically guided dosage regimen, the research team found no evidence of THC intoxication when using CBD-enriched whole plant extracts.

“What makes these results really exciting is it opens up as a treatment option for kids who have failed to respond to traditional medications,” said Dr. Richard Huntsman (M.D), a pediatric neurologist who led the study.

Three of the seven children in the USask study–mainly funded by Saskatchewan’s Jim Pattison Children’s Hospital Foundation–stopped having seizures altogether.

“Some of the improvements in quality of life were really dramatic with some of the children having huge improvements in their ability to communicate with their families. Some of these children started to talk or crawl for the first time. They became more interactive with their families and loved ones,” said Dr. Huntsman.

Several studies have shown that cannabis products containing CBD can be effective in helping to control seizures in children with epileptic encephalopathy, a severe form of epilepsy which begins in childhood. Despite this, many children cannot access these products because there is very little guidance for physicians on which doses to use and some health-care providers are concerned about possible intoxication from THC.

This research found that most of the children had a reduction in seizures with a twice-daily dose of CBD totaling 5-6 milligrams of cannabis extract per kilogram of weight (mg/kg) per day. By the time a CBD dose of 10-12 mg/kg per day was achieved, all children experienced a reduction in their seizures, most by more than 50 percent.

“What is really important is that we have been able to dispel in a scientific manner some of the concerns about how to dose these products and the possibility of them causing a ‘high’ in these children. We did this by slowly increasing the dose of cannabis extract in a very tightly regulated manner. We watched the children very closely for side effects and measured blood levels of CBD and THC,” said Dr. Huntsman,

The children had drug-resistant epilepsy, failing to respond to at least two forms of anti-convulsant medication. They had been prescribed several anti-convulsant medications yet continued to have seizures, with one child experiencing 1,223 in the month leading up to the study.

“We are very proud to support this important pediatric research, which is making such a difference in the lives of children who have severe epilepsy,” said Brynn Boback-Lane, President and CEO of Jim Pattison Children’s Hospital Foundation.

“This groundbreaking study is giving hope and improved health outcomes. It is heartening to have donors that see the value of such important work.”

Allyssa Sanderson’s eight-year-old son Ben from Prince Albert, Sask. was one of the participants in the study. Ben was born without complications but later developed infantile spasms. When Ben was two, he was diagnosed with Lennox-Gastaut syndrome, a severe form of epilepsy.

Studying an evidence-based scientifically guided dosage regimen, the research team found no evidence of THC intoxication when using CBD-enriched whole plant extracts. The image is in the public domain.

Despite trying multiple medications and treatments, Ben’s seizures were unpredictable. He was seizure-free on some days, but on others had 150 seizures a day.

“Ben was very lethargic and would just lay there and have seizures all day. He wasn’t active and didn’t even want to eat. His eyes looked dull, and he didn’t focus on anything. He really looked lifeless,” Allyssa explained. “I knew this trial was a last resort for my son.”

Once Ben started taking CBD, he began showing improvements in his seizure frequency and then became seizure-free during the study.

“I was seeing the change in Ben every single day. I was thankful as I watched his little personality come out. He was back to his silly self that I hadn’t seen in years. He was stronger. I believe this research is one of the greatest things to happen for kids with epilepsy,” Allyssa said.

The Benefits of CBD Oil For Epilepsy

The benefits of CBD oil for epilepsy include:
  • Alleviates convulsions
  • Protects the neurons from damage
  • Regulates excess brain activity
  • Reduces brain inflammation
  • Promotes GABA activity in the brain

Despite all the research we have in the effects of CBD for epileptic conditions, we still don’t know the exact mechanisms involved.

Seizures are incredibly complex, and the causes generally involve multiple separate organ dysfunctions combining to produce symptoms. Therefore, deciding which part of this interaction is improved with CBD is hard to pinpoint.

Here are the current theories based on clinical, in vivo, and in vitro research findings.

1. Reduces Epileptic Convulsions

Epileptic-induced rodents were given various concentrations of CBD. The highest-dose group (100 mg per kg) showed significant improvements in muscle contractions during seizures [4].

2. Regulates Electrical Activity in The Brain

Seizures are characterized by excessive and chaotic electrical activity in the brain.

Electrical activity is largely regulated by the vanilloid receptors (TRPV).

CBD and CBDV have both been shown to regulate these vanilloid receptors (TRPV1) in the brain [1].

When TRPV1 is overactivated for any reason, it induces epileptic seizures. CBD and CBDV have been found to control the overactivity of this receptor in the brain — potentially leading to fewer seizures.

3. Protects The Brain Cells

CBD and many other cannabinoids in the cannabis plant have been shown to have broad, non-specific neuroprotective effects on the brain. Some of these neuroprotective effects are thought to be partly responsible for CBD’s powerful anti-epileptic activity.

CBD is protective for other neurological conditions, including:

4. Inhibits Brain Inflammation

As with most neurological disorders, inflammation is a huge factor in epilepsy [10].

A lot of evidence suggests CBD is an effective anti-inflammatory compound for the brain — potentially alleviating one of the significant factors for neurological disorders such as epilepsy.

CBD is effective because its fat-soluble nature allows it to pass through the blood-brain barrier efficiently. It also offers anti-inflammatory effects through some different inflammatory messengers and immune-regulating cells [11, 12, 13].

What’s The Dose of CBD Oil For Seizures?

Figuring out the right dose of CBD for epilepsy is difficult — and will likely require some trial and error.

Everybody responds to CBD differently. Some people require high doses; others much lower. You won’t know for sure the ideal dose you need without experience.

In general, people with epilepsy require higher-than-average dosing to get the maximum amount of benefits from the compound. This is why we recommend buying a high-potency CBD oil. If you buy a low-potency CBD product and then realize you need a high dose to see any benefits, you’re likely to need to take the entire bottle for a single dose. High-potency oils last longer by delivering the same amount of CBD in a smaller amount of oil or capsules.

With that said, we recommend starting at a low dose and building up gradually over time until you reach a dose that provides the level of relief you’re looking for.

Recommended strength for epilepsy: high strength

Tips for Getting the Most Out of CBD Supplements for Epilepsy:
  1. Always seek out high-quality CBD products to avoid contamination with heavy metals or pesticides — which can make epilepsy even worse
  2. Use full-spectrum extracts for the best results — research suggests these extracts are more effective than isolated or purified CBD products
  3. Increase the dose gradually — start with a low dose and build up to a higher dose until symptoms are reduced
  4. Combine CBD with other antiepileptic treatments and dietary changes — such as a ketogenic diet, regular exercise, and psychotherapy when appropriate
  5. Take CBD regularly — the effects are more pronounced after several weeks of regular use

What is Epilepsy?

Epilepsy is a spectrum of disorders involving the primary symptom: unprovoked seizures. Other health issues may or may not also be present. Everybody experiences epilepsy differently, and seizures can vary significantly in frequency and severity.

Some epileptic patients suffer from seizures one or two times per year, while others can experience nearly nonstop seizures throughout the day.

Seizures can involve whole-body convulsions (grand mal), remain confined to one limb (Jacksonian seizures), or involve lapses in consciousness (petit mal). We’ll include more on the different types of seizures later.

The seizure itself is the result of dysfunctional electrical activity in the brain — which can originate from anywhere in the brain. This abnormal electrical activity can remain confined to the area in which it started, or it can spread throughout the entire brain. In most cases, the latter is more severe.

People suffering from epilepsy usually have the condition for the rest of their life. However, it can come and go from one year to the next. Some people report being seizure-free for up to six years before having another seizure.

There are many different forms of epilepsy and numerous potential causes for each one. It can, therefore, be difficult for doctors to pinpoint the exact cause of the seizures in many cases.

Symptoms of Epilepsy

  • Temporary confusion
  • Prolonged staring
  • Uncontrollable jerking movements
  • Loss of consciousness
  • A sudden sense of intense fear or anxiety
  • Lapses in memory

What Causes Seizures & Epilepsy?

Seizures are the primary symptoms of epilepsy. Although epilepsy is characterized by recurring seizures, there are other causes, such as high fever or head injuries.

The brain is made up of billions of specialized cells called neurons. They’re designed to transfer messages throughout the brain and body using electrical impulses. To do this effectively, the neurons in the brain need to work together.

In the event of a seizure, large groups of neurons will send messages at the same time (hypersynchrony), disrupting normal brain function. This can cause changes in taste, vision, sound, smell, language, posture, memory, emotion, and consciousness.

Some seizures will affect the entire brain; others only specific regions. The severity of the electrical activity and how much of the brain is affected will determine the individual side-effects. Ultimately, no seizure is the same.

Causes of Seizures May Include:

There are different forms that seizures can happen depending on the individual and the type of epilepsy they have. Some people will experience one, two, or all three.

Three Types of Epilepsy

There are three different types of epilepsy.

The main differentiating factor for epilepsy is the types of seizures experienced, but there are other factors depending on the site of electrical dysfunction in the brain and the underlying cause of the condition.

Over the past decade, a group called the International League Against Epilepsy (ILAE) has been working hard to standardize the terminology used in diagnosing and describing epilepsy.

Here are the definitions listed in their 2017 outline.

1. Focal Onset

Focal onset epileptics experience abnormal electrical activity in only specific regions of the brain. They used to be called “partial seizures.”

There are four types of focal seizures:

  1. Focal-aware seizures — the patient is aware of the seizure while it’s taking place.
  2. Focal-impaired awareness seizures — the patient is unaware or unconscious during the seizure.
  3. Focal motor seizures — these involve movements such as rubbing hands together or twitching during the seizure.
  4. Focal non-motor seizures — these do not involve muscle twitches or movements, but instead shifts in thinking and emotions during the seizure. Waves of heat or cold, a racing heart, or intense emotions are common.
2. Generalized Onset

Generalized onset seizures involve abnormal electrical activity throughout both sides of the brain, resulting in widespread side effects throughout the body.

Within generalized onset epilepsies, there are two types — motor onset and non-motor onset.

Motor onset conditions used to be referred to as “grand mal” seizures — in some circles, they still are. They result in full-body seizures and an inability to control the body while the seizures are occurring. They can last anywhere from a few seconds to a few hours. CBD is useful for these types of seizures due to its ability to relax muscle contractions around the body.

Non-motor onset seizure conditions are usually called “absence” seizures. They involve periods of staring into space or repetitive movements (such as tapping hands or licking lips). These types of seizures make it seem as though the person having the seizure is no longer there — hence the name “absence seizures.”

3. Unknown Onset

As the name implies, any seizure where the source of the seizure can’t be identified is referred to as having an unknown onset. These seizures are especially challenging to treat.

Epileptic Syndromes

The new terminology outlined by the ILAE does not change the characterization of epileptic syndromes — of which there are quite a few.

The Most Common Epileptic Syndromes Include:
  1. Lennox-Gastaut Syndrome (LGS)
  2. Dravet Syndrome
  3. Juvenile Myoclonic Epilepsy (JME)
  4. Benign rolandic epilepsy (BRE)
  5. Childhood absence epilepsy (CAE)
  6. Infantile spasms (or West syndrome)

The Risks of Epilepsy

Epilepsy can endanger the safety of those affected. It can be risky to drive, work, or even cross the street. If a seizure comes on suddenly, those affected are unlikely to get out of harm’s way.

Conventional Treatment Options for Epilepsy

It’s important to remember that epilepsy is a spectrum. Certain medications or other treatment options tend to work better for some forms of epilepsy over others. In some cases, no conventional treatment works for the patient’s requirement — these are usually the people that begin using CBD.

Medications for Epilepsy Include:

Medical Marijuana for Epilepsy

It’s clear that marijuana is a useful supplement for different forms of epilepsy, including both generalized and focal, along with some epileptic syndromes.

Studies have shown that CBD is the active constituent of these effects. Interestingly, a meta-analysis recently showed that although any form of CBD offers benefits, a full-spectrum CBD extract containing a variety of other cannabinoids was more beneficial and had fewer side effects overall [2].

For this reason, we recommend using a quality full-spectrum product over pharmaceutical versions such as Sativex® or Epidolex®, as well as CBD products made from 99.9% pure CBD isolates.

It’s likely the other cannabinoids in the full-spectrum extracts, along with the terpenes and various other phytochemicals, work synergistically to produce the associated benefits.

The Story of Charlotte Figi

Charlotte Figi is an American girl with a severe case of Dravet syndrome who changed the way we treat epilepsy forever.

When Charlotte was just six years old, her parents signed a “do not resuscitate” order for their little girl. This meant that in the event of an emergency that saw Charlotte stop breathing or her heart stops beating, medical professionals would not be allowed to step in and save her life.

Her symptoms were very severe — she’d often experience hundreds of seizures each week. She could barely speak, and her quality of life was at an all-time low.

Even after trying numerous medications, the Figis saw virtually no improvement in their daughter’s condition.

It wasn’t until 2011 that the Figis decided to try cannabis for their daughter — and it worked.

Here seizures dropped from 1200 per month to about 3 — and the ones she had were significantly less severe. She can now talk, play, and live a life much closer to “normal.”

The media attention that followed this story exploded and is arguably the catalyst that led to the establishment of the CBD market we’re now experiencing. This is because it was discovered that CBD was the compound responsible for treating Charlotte’s condition. Researchers flocked to test it out on other types of epilepsy, as well as other medical conditions.

Guide to Using CBD for Epilepsy

CBD is becoming one of the most common treatment options for epileptics. However, with poor regulations in the CBD market, there is an alarming amount of low-quality products containing contaminants such as heavy metals or pesticides that can damage the neurons and potentially make epilepsy symptoms worse.

There are also a lot of companies selling oils with specific amounts of CBD listed on the bottle — but when tested by third parties, they’re found to contain only a fraction of the amount advertised.

When it comes to using CBD for epilepsy, it’s critical that you use only high-quality, contaminant-free, and high-potency products.

It’s also been proven through meta-analysis that a full-spectrum extract rich in CBD and other cannabinoids and terpenes has the biggest impact on epileptic conditions [2].

For this reason, we recommend searching specifically for a product with at least 50 mg per mL of CBD that is made from certified organic hemp and has publicly listed third-party test results.

How to Get a Prescription for Medical Cannabis & CBD

Although every country has its own rules regarding the use of medical marijuana, most countries with a medical program will prescribe it for epilepsy.

The National Institute of Health and Clinical Excellence is working on official guidance for prescribing medical cannabis.

Epilepsy treatment is expected to be one of the primary focus points for this piece, which is expected to be completed at the end of 2020.

If your country (or state) doesn’t have a medical marijuana program, low-THC hemp extracts are an excellent alternative. These are classified as nutritional supplements in most countries and are non-psychoactive.

Finding the Right CBD Supplements for Epilepsy

There are so many different cannabis companies selling CBD oils, capsules, and topicals — it can be hard to separate the good from the bad.

As a general guide, always look for the following:

  • Products containing full-spectrum extracts
  • Potencies of at least 50 mg per mL
  • Productos with third-party lab tests posted
  • Products made from certified organic hemp
  • Extracts containing low THC (less than 0.3%)
1. CBD Oils For Epilepsy

CBD oils are the most popular form of CBD because it simplifies dosing, it can be stored for long periods of time, it is one of the cheapest forms of CBD and has high bioavailability.

2. CBD Capsules For Epilepsy

CBD capsules provide another great option for people who want a simple way to get their dose without having to measure or taste CBD oil. However, capsules are slightly more expensive on average than oils.

3. CBD Edibles For Epilepsy

Edible CBD products are also available — but aren’t recommended for daily CBD supplementation due to the high sugar content and inconsistencies with dosing. These are great for occasional use to make your CBD use more interesting (and flavorful) but not ideal for everyday use.

4. CBD Vape Oils & E-Liquids For Epilepsy

CBD vape oils and vape pens are also an option, and many people with epilepsy choose to use this method to get their dose of CBD. The benefit with vape oils is that the CBD enters the bloodstream almost immediately, offering fast relief from symptoms.

Unless vaping irritates your lungs, or you’d rather avoid it altogether, keep some vape oil on hand to address symptom flare-ups promptly without having to wait for oils or capsules to absorb through the digestive tract.

CBD & Epilepsy: What the Research Says

Cannabidiol (CBD) is one of over 66 different cannabinoids found in the cannabis plant.

There are two main cannabinoids in the cannabis plant that account for more than half the total cannabinoid content. CBD is non-psychoactive (meaning it won’t make you feel high). It’s also the primary ingredient responsible for the antiepileptic effects of the cannabis plant.

A pharmaceutical CBD preparation — Epidolex (cannabidiol) — was approved in 2018 for the treatment of Lennox-Gastaut syndrome (LGS) and Dravet syndrome — two forms of epilepsy known for resisting treatment.

A recent meta-analysis involving 670 people with various forms of epilepsy found that 71% of people taking CBD-rich full-spectrum extracts experienced reduced seizure frequency [2].

Roughly 40% of the people in this study had the frequency of seizures cut in half, and a quarter had an incredible 70% drop in episodes.

Amazingly, 10% of the group were reported to be seizure-free at the end of the study.

CBD works — there’s no doubt about it. The hard part now is determining exactly how it works.

We’re still uncovering exactly how CBD is useful for treating epilepsy and seizures. Even GW Pharmaceuticals admits on its website that the mechanism of action isn’t clear. GW Pharmaceuticals is the creator of Sativex® — the new cannabinoid-based pharmaceutical that’s been gaining a lot of hype lately as a breakthrough new treatment for epilepsy.

There are a few good theories, however.

Final Verdict: Can CBD Help With Epilepsy & Seizures?

CBD is perhaps one of the most exciting new treatment options for epilepsy — including epileptic syndromes such as Dravet syndrome that are problematically resistant to treatment.

To get the most out of CBD supplementation for epilepsy, a high-quality, full-spectrum extract should be used. It’s also recommended to opt for a high-potency option because, in most cases, high doses are needed to get the same level of benefits reported in the scientific literature.

Check out some of our recent reviews to vet a company and their product before you make a purchase. Remember only to buy products that are made from certified organic hemp and have been tested for purity and potency by third-party labs.

If a product doesn’t check these boxes, it’s wise to avoid taking them for epilepsy. You don’t want to make symptoms worse.
