This week the New England Journal of Medicine published a double-blind study on the effectiveness of Cannabidiol (CBD) on seizures demonstrating that it was safe and effective for kids whose seizures could not be effectively controlled with typical anticonvulsants. The publication of the study set off a media storm with the results reported in hundreds of newspapers and on electronic media. The actual study focused on individuals with a Dravet syndrome diagnosis and so it is difficult to know how well it can be applied to individuals with MECP2 duplication. Nevertheless, there are some interesting findings and likely impacts with potential implications. Continue reading

Drop seizures are extremely common among individuals with MECP2 duplication syndrome. There is a sudden loss of muscle tone, and if the individual is not supported, he or she drops suddenly to floor, sometimes resulting in injury. Usually these are brief and it is over in a second, but sometimes they come in clusters.
While these drops are certainly one of the most, if not the absolute most, common seizures in MECP2 duplication syndrome, there are actually two kinds of “drops” that look pretty much the same, but are fundamentally very different. It is hard to tell them apart, and at least some individuals with MECP2 duplication syndrome, have both kinds. It may be helpful to figure out which kind is occurring, but it can be really hard to figure out, and it appears that at least some individuals experience both atonic and myoclonic drops.
So what’s the difference? ATONIC VS MYOCLONIC-ATONIC Continue reading
This post expresses my personal opinion. It is merely a theory for discussion and possibly a hypothesis that will or will not be supported by evidence over time. Simply stated, my theory is:
A: There are different kinds of seizure disorders.
B. It is possible for an individual to have more than one kind of seizure disorder.
C. Individuals with MECP2 Duplication Syndrome often have multiple seizure disorders. Continue reading
Several new studies provide encouraging results about the use of cannabidiol (CBD) oil to treat seizure disorders that are not controlled by other medications. Research also, however, points toward important cautions.
Already in 2016,at least nine studies have been published on CBD and seizures. Two 2016 studies, one from Israel (Tzadok et al.,, 2016) and one the United States (Devinsky et al., 2016) are generally reporting particularly encouraging results. This is not to say the others are negative, just less relevant. The two discussed here are important because they include some results Continue reading
A few days ago, I posted a video (Drop Seizure Video) on this blog. It showed a girl having “drops” or what the video caption called “infantile spasms.” A large number of MECP2 Duplication Syndrome family members agreed that although their affected family members had many kinds of seizures, this looked a lot like what some of their drops look like. I definitely found this very interesting, since infantile spasms are generally described as starting before one year of age, and are very rare in older children or adults.
Thanks to the internet, I was able to find out more. I got some great leads from two colleagues in Kyoto Japan and Doha Qatar Continue reading
This YouTube video looks a lot like what has been described as a drop in individuals with individuals with MECP2 Duplication Syndrome. The individual in this video does not have MECP2 Duplication Syndrome, but the video provides a good example of what some drops look like.
The text below is the original text accompanying the video on YouTube. Continue reading
Seizures present a major problem for individuals with MECP2 Duplication Syndrome. Most, if not all, will develop seizures at some point in their lives, and their seizures are typically extremely difficult to treat with conventional anticonvulsants. Some families have attempted to treat seizures with Cannabidiol (CBD) after widespread publicity has touted its apparent effectiveness in treating seizures in children and adults with uncontrolled epilepsy. Officially the verdict is still out on its effectiveness, but the good news is that their is now a flood of new scientific reviews and studies emerging and generally it is quite supportive of CBD. Listed here are a few recent publications and a brief summary of relevant findings.
Hussain, S. A., Zhou, R., Jacobson, C., Weng, J., Cheng, E., Lay, J., et al. (2015). Perceived efficacy of cannabidiol-enriched cannabis extracts for treatment of pediatric epilepsy: A potential role for infantile spasms and Lennox-Gastaut syndrome. Epilepsy & Behavior, 47, 138-141.
This was a survey of 117 parents Continue reading
Some very encouraging news. Researchers at at New York University’s Langone Medical Center have reported results from clinical trials of Epidiolex, a pharmaceutical preparartion of CBD Cannabidiol. The study was structured to determine if the medication was safe, not to measure effectiveness as a an anticonvulsant. Nevertheless, 80% of the participants in the study decreases in seizure activity and on average. The average result for participants was a 54% reduction in seizures after 12 weeks of treatment. Additional clinical trials are still in progress. Continue reading
I need to start this post with a disclaimer. This post suggests that it may be worth asking your child’s doctor about checking Vitamin D levels if your child has MECP2 Duplication Syndrome. If there are signs of deficiency, it suggests discussing supplementation with the doctor. It is not intended to recommend supplementing vitamin D unless a deficiency is identified or without your child’s doctor’s approval, and it is not recommending excessive doses of vitamin D. Having said that, here are the reasons that checking might be worthwhile. Continue reading
