Cannabinoid therapy in epilepsy

Purpose of review To review the history, pharmacology, and clinical science of cannabidiol (CBD) in the treatment of epilepsy. Recent findings Phase III randomized controlled trials and prospective open label trials have provided efficacy and safety data for the use of CBD in pediatric onset severe epilepsies. The product that was studied in the vast majority of these published trials, Epidiolex (>99% of CBD and <0.10% Δ9-tetrahydrocannabinol (THC); GW pharmaceuticals, Cambridge, UK), has now been FDA approved based on this published data. Summary Identification of CBD, Δ9-THC, and the endocannabinoid system in the mid-20th century has led to advancement of cannabis-based therapies for epilepsy. Based on clinical trial data, Epidiolex is the first CBD medication approved by a national regulatory agency (US Food and Drug Administration for Dravet and Lennox Gastaut syndrome; European Medicines Agency for Lennox Gastaut syndrome). Approval of CBD as a treatment for these rare and severe pediatric-onset epilepsy syndromes is an important milestone, but the complete spectrum of use of cannabis-derived products, and the use of CBD for other epilepsy syndromes remains to be determined.

UPI: Kids with psych disorders most likely to take dangerous viral challenges

The “choking game” — and other clearly ill-advised and dangerous internet challenges — leave many parents wondering what drives teens to take the bait and participate. Now, a new study suggests that an underlying psychological disorder may be one reason why some kids jump at online dares such as the “Bird Box” challenge, where people walk around blindfolded, and the Tide Pod challenge, daring people to eat laundry detergent.

The emerging influential role of microglia in neurology

In her most catchily titled book, The Angel and the Assassin , Donna Jackson Nakazawa highlighed nerve cells which have hitherto been very little acknowledged – microglia . Long ignored as bit players in the big league of the nervous system, Nakazawa colourfully illustrated what many neuroscientists are beginning to realise: the small size of microglia belies their huge influence ; m icroglia are, after all, the defence force of the nervous system, protecting the brain from microbial invaders . In keeping with their small size, their role is to surreptitiously present the antigens of invading bugs to T cells , the toffs who actually carry out the final hatchet job . It is therefore not surprising that any dysfunction of microglia will come with significant clinical consequences . By GerryShaw – Own work , CC BY-SA 3.0 , Link The most important clinical fallout of dysfunctional microglia appears to be the emergence of dementia. It is indeed spec...
