Epilepsy

Posted | 2 comments


Epileptic seizures are caused by a disruption of the signal transduction in the brains. An attack is often accompanied by the convulsing of the body, falling, strange movement and losing consciousness. Epilepsy is not a single disease but a family of disorders characterized by an increased risk of getting a seizure as described. Cannabinoids such as CBD may have a beneficial effect on certain types of epilepsy.

What does science tell us?

Stories about the use of cannabis as a remedy for epilepsy have been around for thousands of years. In 1840 it is first described in scientific literature [1]. This publication describes how a child with epilepsy was successfully treated with cannabis. Strangely, there are only a few studies done later in time that examined the effect of cannabis on epilepsy in humans. Evidence for the effectiveness of cannabis on epilepsy comes primarily from animal studies or personal testimonies.

 

In one of the few clinical studies that have been performed fifteen subjects suffering from epilepsy were divided into two groups [2]. One group received 200 to 300mg CBD per day for a period of 4.5 months, the other group received a placebo. Of the eight people who received CBD, four were completely symptom free throughout the whole period, three of them had fewer complaints and on one patient CBD had no effect. In the placebo group, there was one patient who clearly revamped, no effect was observed in the other six.

In animal studies that induced epileptic seizures in mice, it was found that mice have fewer attacks when they had been given CBD [3].

 

CBD compared to THC

THC and CBD have also been compared in terms of their efficacy against epilepsy. CBD turned out to be more reliable in blocking epileptic seizures in comparison to THC. In children who are refractory to standard anti-epileptic medication CBD can possibly be a solution. Moreover, CBD is better tolerated by children than regular medication and gives no adverse motoric side effects. And last but not least, there are no indications that CBD is neurotoxic [4,5].

 

Is a new medicine needed to treat epilepsy?

There is already a lot of different medication available for treating epilepsy, but 30% of patients continue to have uncontrolled seizures, no matter what medication they try. Furthermore, it turns out that in 50% of the cases a drug which helped against epilepsy at first instance, no longer works later in time. So there definitely is a need for new and better tools in the fight against epilepsy.

  1. Hoi, ik heb een vraag. Onze dochter van acht jaar heeft sinds een jaar abscence epilepsie. Nu willen wij gaan kijken of de CBD olie haar kan helpen hierbij. Welke kunnen wij dan het beste gebruiken met of zonder thc ? Uiteraard gaan wij eerst in overleg met de neuroloog en kinderarts om te kijken of zij hier aan mee willen werken.

    Mvg, Vera

    • Beste Vera,
      Dank voor je vraag. Allereerst willen we benadrukken dat wij van CBD-medicatie.nl geen medici zijn, dus ook geen medisch advies kunnen geven. Wel kunnen we natuurlijk proberen mee te denken. Zo weten we dat er momenteel studies worden gedaan naar de effectiviteit van CBD tegen bepaalde vormen van epilepsie bij kinderen, zodra hier meer over bekend wordt zullen wij daar ook over schrijven. CBD lijkt als middel tegen epilepsie veelbelovender dan THC. Dat komt goed uit, want zeker bij kinderen heeft een middel zonder THC de voorkeur, vanwege het psychoactieve effect (high of stoned worden) van THC. Hebben jullie inmiddels overleg met neuroloog en kinderarts gehad? We horen graag jullie ervaringen!
