cbd and seizure disorders

Cannabis-derived cannabinoids have neuroactive properties. Recently, there has been emerging interest in the use of cannabidiol (CBD)-enriched products for treatment of drug-resistant epilepsy. In 2018, the FDA approved the use of CBD-rich Epidiolex for two severe forms of epilepsy in children (Lennox-Gastaut and Dravet syndromes). Experimental research supports the use of CBD in many CNS disorders, though the mechanisms underlying its anticonvulsant and neuroprotective effects remain unclear. CBD has been shown to reduce inflammation, protect against neuronal loss, normalize neurogenesis, and act as an antioxidant. These actions appear to be due to the multimodal mechanism of action of CBD in the brain. This chapter briefly describes the current information on cannabis pharmacology with an emphasis on the clinical utility of CBD in the treatment of refractory epilepsies and other related seizure conditions. Clinical trials are ongoing for other forms of epilepsy and refractory seizures associated with infantile spasms, tuberous sclerosis, and Rett syndrome. Overall, adjunct CBD has been found to be generally safe and effective for treatment-resistant seizures in children with severe early-onset epilepsy. Whether an add-on CBD is efficacious for the long-term treatment of various epilepsy and seizure types in adults being tested in various clinical trials.

They found that CBD may reduce the adverse effects associated with anti-seizure medications, and seems to improve other aspects of health and quality of life for patients.

Participants also were asked about possible adverse effects related to their CBD use. Among the 280 users, the majority (79%) did not report any adverse effects. The remaining reported negative factors such as drowsiness (11%), high or prohibitive product cost (4%), worsening of epilepsy symptoms (4%), concerns about legal issues (3%) and worries about problematic drug interactions (1%).

For their evaluation, the researchers analyzed data gathered between April 2016 and July 2020 from 418 participants — 230 women and 188 men — with 205 (49%) at least age 18 and 213 (51%) age 18 or younger. The participants included 71 adults with epilepsy who used artisanal CBD products for medicinal purposes and 209 who were caregivers of children or dependent adults to whom artisanal CBD products were given. The control group consisted of 29 adults with epilepsy who were considering the use of CBD products and 109 caregivers who were considering it for a dependent child or adult patient.
