Highly purified cannabidiol in the treatment of drug-resistant epilepsies: A real-life impact on seizure frequency, quality of life, behavior, and sleep patterns from a single Italian center

Seizure frequency in treatment-resistant epilepsies seems to be decreased by cannabidiol (CBD), but contrasting data are available on its effect on sleep, behavior, and quality of life (QoL), and no data is reported on its effect on parental stress in patients with epilepsy (PWE). Thus, we conducted a retrospective study on a cohort of children and adults with drug-resistant epilepsy (DRE) who had been treated with highly purified, pharmaceutical-grade CBD to evaluate its effects on seizure frequency, QoL, behavior, parental stress, and sleep. Eighteen patients (12 adults and 6 children) were included in the cohort and followed for a median of 9 months.

Use of cannabinol in the treatment of epilepsy: Lennox-Gastaut Syndrome , Dravet, and Tuberous Sclerosis Complex

Purpose: The objective of this systematic review with meta-analysis was to evaluate the efficiency, safety and short and long term tolerability of Cannabidiol CBD, as an adjunct treatment , in children and adults with Dravet Syndrome (SD) and Lennox Gastaut Syndrome(LGS) or Tuberous Sclerosis Complex with inadequate control of seizures.

Cannabidiol in refractory status epilepticus: A review of clinical experiences

To summarize and evaluate clinical experiences with refractory status epilepticus in which cannabidiol (CBD) was utilized for cessation of seizure activity. A comprehensive literature review was performed on PubMED, MEDLINE, Scopus, and CINAHL between May – June 2022 with the assistance of a medical reference librarian using the following search terms: “Cannabidiol” [MAJR], “Status Epilepticus” [MAJR], “New-Onset Refractory Status Epilepticus”, and “cannabidiol.” Reports that provided dosing regimens and patient outcomes were included.

Long-term use of cannabidiol-enriched medical cannabis in a prospective cohort of children with drug-resistant developmental and epileptic encephalopathy

We report our findings regarding effectiveness, safety, and tolerability of cannabidiol (CBD)-enriched medical cannabis as add-on therapy in children with drug-resistant epileptic encephalopathies (DEEs) after a median follow-up of 20 months.

Current neurologic treatment and emerging therapies in CDKL5 deficiency disorder

CDKL5 deficiency disorder (CDD) is associated with refractory infantile onset epilepsy, global developmental delay, and variable features that include sleep, behavioral disturbances, and movement disorders. Current treatment is primarily symptom-based and informed by experience in caring for this population.

Long-term safety and efficacy of add-on cannabidiol in patients with Lennox–Gastaut syndrome: Results of a long-term open-label extension trial

Lennox–Gastaut syndrome (LGS) is an epileptic encephalopathy that is often treatment resistant. Efficacy and safety of add-on cannabidiol (CBD) to treat seizures associated with LGS was demonstrated in two randomized controlled trials (RCTs). Patients who completed the RCTs were invited to enroll in this long-term open-label extension (OLE) trial, GWPCARE5 (NCT02224573). We present the final analysis of safety and efficacy outcomes from GWPCARE5.
