Cannabis use in the treatment of epilepsy has garnered significant attention due to promising results with cannabinoids, especially cannabidiol (CBD), in managing seizures. Epilepsy is a neurological disorder characterized by recurrent seizures that can vary in frequency and severity. Traditional treatments do not work effectively for all patients, leading many to explore alternative options such as cannabis-derived therapies. Cannabinoids and Epilepsy The two main cannabinoids in cannabis, CBD and tetrahydrocannabinol (THC), interact with the endocannabinoid system (ECS), which plays l a cannabis role in regulating neuronal activity.
However, their effects differ: while THC is psychoactive and can exacerbate seizures in some individuals, CBD is non-psychoactive and has shown anticonvulsant properties without the "high." This makes CBD particularly attractive for epilepsy treatment. Clinical Evidence and Research Epidiolex, the first FDA-approved CBD medication, has been a breakthrough for epilepsy treatment. Approved in 2018, Epidiolex is used to treat two severe forms of childhood epilepsy: Dravet syndrome and Lennox-Gastaut syndrome.
Clinical trials have shown that Epidiolex can reduce seizure frequency in these conditions significantly, offering hope to patients who have not responded to conventional therapies. In a pivotal clinical study, patients with Lennox-Gastaut syndrome who received CBD experienced a median reduction of 41.9% in seizures, compared to a 17% reduction in the placebo group. Similar results were observed for Dravet syndrome, with patients showing a 39% reduction in seizure frequency on average.
Research into CBD’s anticonvulsant mechanisms suggests that CBD may inhibit neuronal excitability and modulate calcium levels in the brain, helping to control seizures. By reducing neuronal hyperactivity, CBD may provide a therapeutic effect for those with treatment-resistant epilepsy. Mechanism of Action The exact mechanisms by which CBD controls seizures are still under investigation, but current theories include: Modulation of GABA Receptors: GABA (gamma-aminobutyric acid) is a neurotransmitter that helps reduce neuronal excitability.
CBD may enhance GABA’s calming effects, reducing seizure frequency. Calcium Regulation: Abnormal calcium levels in neurons can trigger seizures. CBD may regulate these levels, preventing excessive neuronal firing. Antioxidant and Anti-Inflammatory Properties: CBD’s antioxidant effects help reduce oxidative stress and inflammation, which can be associated with seizure activity.
