Information about the use of cannabis oil for epilepsy to gain seizure control. for many of the medical benefits associated with cannabis. Only certain patients have access to the cannabis-based oil under Texas' restrictive law to take advantage of a three-year-old law that makes cannabidiol oil with any diagnosis besides intractable epilepsy to use CBD oil. Goals and Expectations · Risks and Benefits I am curious if anyone has tried the new CBD oil to control their epilepsy. If this round of medications doesn't work I am really thinking about the CBD oil. the challenges of living with epilepsy and to accelerate therapies to stop seizures, find cures, and save lives. follow us.
Benefits Using Oil CBD for The Epilepsy of
Compared with baseline, the median monthly frequency of convulsive seizures defined as the sum of tonic-clonic, tonic, clonic, and atonic seizures decreased from Median percent changes in seizure frequency are shown in Fig. Non-convulsive seizures were not significantly affected by CBD therapy. Median percent reduction in seizure frequency in the three randomized adjunctive-therapy placebo-controlled efficacy trials of cannabidiol CBD reported to date in patients with Dravet syndrome 85 and Lennox-Gastaut syndrome.
For patients with Lennox-Gastaut syndrome, seizure frequency refers to drop seizures. P values refer to comparisons between each CBD group and corresponding placebo group.
For further details, see text. Somnolence, diarrhea, and decreased appetite were the most common CBD-associated adverse events Table 2. Eighteen of the 22 CBD-treated patients who developed somnolence were on clobazam comedication.
Adverse events appeared mostly during the first two weeks of therapy, and there were instances in which the dose of CBD or other medications were reduced. No information, however, was reported on how often the dose of concomitant clobazam was reduced.
Eight patients in the CBD group discontinued the trial prematurely due to adverse events in three cases, marked elevation of liver enzymes , compared with one patient in the placebo group who also had a marked elevation in liver enzymes. Overall, elevated aminotransferases levels occurred in 12 patients in the CBD group and one in the placebo group, all of whom were on concomitant valproate therapy. In the nine patients with raised aminotransferases who did not discontinued treatment, liver enzymes reverted to normal on continuation of therapy.
Adverse events most commonly reported in the randomized double-bind placebo-controlled trial of CBD in comparison with placebo in patients with Dravet syndrome Overall, this trial provides for the first time robust evidence that CBD added-on to pre-existing AED treatment reduces the frequency of convulsive seizures in children and young adults with Dravet syndrome.
Interestingly, no significant differences between groups were found in sleep scores, behavioral adaptation Vineland-II scores, and Quality of Life in Childhood Epilepsy scores, even though duration of treatment was relatively short and possibly insufficient to determine changes in these parameters. A major weakness in the presentation of the trial results is the failure to report changes in plasma concentrations of concomitant AEDs and, most notably, clobazam and N-desmethylclobazam.
Two well controlled double-blind trials in patients with Lennox-Gastaut syndrome have been completed, but results to date have only been reported in summary form. Treatment-related serious adverse events were reported in nine CBD patients and one placebo patient. Elevations in transaminases occurred mostly in patients on concomitant valproate therapy and all resolved. Duration of the trial was 14 weeks 2-week titration and week maintenance.
Total seizures were also significantly reduced in both CBD groups compared with placebo. Some elevations in transaminases were seen. Published reports, however, provide no information on concomitant therapies, and most notably whether, and to what extent, the clinical improvement on CBD therapy could be related to elevation in serum concentrations of other medications, most notably clobazam and N-desmethylclobazam.
The interest in cannabis preparations in the treatment of epilepsies, particularly drug refractory childhood epilepsies, has skyrocketed in recent years. Marijuana and other cannabis products with moderate to high THC content utilized primarily for recreational purposes are generally unsuitable for this indication, not only because evidence for an anti-seizure activity of THC is equivocal and risk of seizure aggravation cannot be excluded, but also because THC is associated with many undesired effects, including addiction liability, psychiatric disorders, cognitive and motor impairment — and, possibly, also cardiovascular toxicity.
Compared with THC, CBD shows a better defined anticonvulsant profile in animal models considered to be predictive of efficacy against focal and generalized seizures. Moreover, CBD is largely devoid of adverse psychoactive effects, and is considered to lack the abuse liability associated with THC-containing products. Improvement in seizure control, often associated with additional benefits on sleep and behaviour, have been reported in a sizeable proportion of cases, 87 but interpretation of these data is made difficult by the uncontrolled nature of the observations.
Additionally, as discussed in this article, there are concerns about the quality and variability of many of the products used, 98 particularly because cannabis treatment is often initiated spontaneously by patients or caregivers without adequate medical supervision.
Evidence concerning the potential anti-seizure efficacy of cannabinoids reached a turning point in the last 12 months, with the completion of the first high-quality placebo-controlled trials of a purified oil-based liquid CBD preparation in patients with Dravet syndrome and Lennox-Gastaut syndrome.
Therefore there is now for the first time class 1 evidence that CBD improves seizure control when added on to other AEDs in patients with two difficult-to-treat epileptic encephalopathies. Available data, however, do not allow to conclude that CBD per se has anti-seizure activity. At least for the trial published in full, 85 a majority of patients were receiving concomitant clobazam therapy, and it is unclear whether the reported seizure benefits, as well as adverse effects, were related to a direct action of CBD, or were mediated by a previously described 5-fold elevation in plasma N-desmethylclobazam levels.
For the two studies in Lennox-Gastaut syndrome, the proportion of patients on concomitant clobazam therapy was not reported, but it is likely to have been significant because clobazam is a frequently used comedication in patients with this syndrome. Clarification of the independent effects of CBD would require re-assessment of trial data for the subgroup of patients not comedicated with clobazam, or the conduction of further studies after excluding such patients or, alternatively, adjusting blindly clobazam dosages to maintain unaltered concentration of N-desmethylclobazam.
Additional well controlled studies are also desirable to determine the potential value of CBD in other seizure types and epilepsy syndromes, including refractory focal epilepsies.
One of the reasons for the utilization of cannabis products to have become so popular among patients and their caregivers is that these products are generally regarded as causing fewer adverse effects compared with traditional AEDs, partly out of the misperception that remedies derived from natural products are unlikely to be harmful.
Although these results are encouraging, further studies are required to evaluate the safety profile of CBD and other cannabis products in greater detail, particularly after long-term exposure and whenever these products are used in subpopulations potentially at risk.
Elevations of liver enzymes have been frequently observed, especially in patients comedicated with valproate, and although they were generally reversible, close observation for signs suggestive of hepatic toxicity is advisable. Nabiximols, an oromucosal spray formulation containing approximately equal amounts of THC and CBD, has been commercially available in several countries for a number of years and has a relatively extensive safety record.
Unlike THC, CBD is not associated with the development of tolerance after repeated administration in various seizure models, and there is no evidence of a withdrawal syndrome developing after CBD discontinuation. These are exciting times for research in cannabinoids. After almost four millennia of their documented medical use in the treatment of seizure disorders, we are very close to obtaining conclusive evidence of their efficacy in some severe epilepsy syndromes.

Cannabis, Cannabidiol, Epilepsy, Seizures, Review. Introduction The history of human use of the Cannabis plant goes back to the dawn of mankind. Open in a separate window. Chemistry and mechanisms of action The genus Cannabis refers to a flowering plant of which there are three main species, Cannabis sativa , Cannabis indica and Cannabis ruderalis.
Table 1 A list of targets and actions reported for CBD based on results of studies in different experimental models and systems 24 — Pharmacological profile in experimental models of seizures and epilepsy Among the many active principles found in the cannabis plant, THC is the most widely investigated for its many actions, including its psychoactive effects and risks associated with overdose and abuse.
CBD In preclinical studies, CBD has been found to be active in a variety of seizures models, including seizures induced by maximal electro-shock 39 — 41 and by pentylentetrazole in rats and mice, 42 — 44 audiogenic seizures in rats 45 and seizures induced by 3-mercaptopropionic acid, bicuculline, picrotoxin, cocaine and isoniazid but not strychnine in mice.
Clinical evidence of efficacy and safety: Well controlled randomized trials The recent flurry of research focused on the potential usefulness of cannabinoids in epilepsy has resulted in the completion of three well controlled randomized trials, all of which evaluated a liquid proprietary oral formulation of CBD. Table 2 Adverse events most commonly reported in the randomized double-bind placebo-controlled trial of CBD in comparison with placebo in patients with Dravet syndrome Double-blind trials in Lennox-Gastaut syndrome Two well controlled double-blind trials in patients with Lennox-Gastaut syndrome have been completed, but results to date have only been reported in summary form.
