Could cannabis curb seizures? Experts weed through the evidence

22.05.2014

The therapeutic potential of medical marijuana and pure cannabidiol (CBD), an active substance in the cannabis plant, for neurologic conditions is highly debated. A series of articles published in Epilepsia, a journal of the International League Against Epilepsy (ILAE), examine the potential use of medical marijuana and CBD in treating severe forms of epilepsy such as Dravet syndrome.

In a case study, Dr. Edward Maa, Chief of the Comprehensive Epilepsy Program at Denver Health in Denver, Colo., details one mother's experience of providing medical marijuana to her child with Dravet syndrome. The adjunct therapy, a strain of cannabis high in CBD and tetrahydrocannabinol (THC) known as Charlotte's Web, was given in conjunction with the patient's antiepileptic drug regimen. The child's seizure frequency was reduced from 50 convulsions per day to 2 to 3 nighttime convulsions per month.

"Colorado is "ground zero" of the medical marijuana debate," says Dr. Maa. "As medical professionals it is important that we further the evidence of whether CBD in cannabis is an effective antiepileptic therapy." Currently, 21 states and the District of Columbia (DC) have legalized marijuana for medical purposes according to GOVERNING magazine.

A counter-point article summarizes current scientific evidence of CBD use in epilepsy and other neurological or psychiatric disorders including anxiety, schizophrenia and addiction. Previous studies found that THC, the primary psychoactive substance and CBD the main non-psychoactive ingredient in cannabis, display anticonvulsive properties in animals. However, this research was conducted in acute animal models and data is limited for chronic recurrent seizures. Recent studies claim medical marijuana with high ratios of CBD to THC are more effective in seizure control, but the data was anecdotal and not well controlled.

"While cannabis has been used to treat epilepsy for centuries, data from double-blind randomized, controlled trials of CBD or THC in epilepsy is lacking," explains Dr. Orrin Devinsky, Director of the Comprehensive Epilepsy Center at NYU Langone Medical Center in New York and Saint Barnabas Institute of Neurology and Neurosurgery in New Jersey. "Randomized controlled studies of CBD in targeted epilepsy groups, such as patients with Dravet or Lennox-Gastaut syndromes, are in the planning stages."

Dr. Maria Roberta Cilio, Director of Research in Pediatric Epilepsy of the Comprehensive Epilepsy Center at UCSF Benioff Children's Hospital in San Francisco, agrees, "There is a critical need for new therapies, especially for childhood-onset treatment-resistant epilepsies that impair quality of life and contribute to learning and behavioral disorders. Rigorous investigation of the safety and efficacy of medical marijuana or individual components such as CBD are necessary for patients with epilepsy before any conclusion is made. "

"There is much interest in the therapeutic potential of medical marijuana and CBD in treating epilepsy," say Drs. Gary Mathern and Astrid Nehlig, Editors-in-Chief of Epilepsia. "We would like your perspective on this important issue and ask that patients, clinicians, and medical professionals visit http://surveys.verticalresponse.com/a/show/1539433/ea840f4206/0 to provide feedback on the use of medical marijuana in epilepsy."

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
