There are three types of epilepsy:
Focal onset - where the abnormal electrical activity is experienced in a specific region of the brain.
Generalised onset - where the abnormal electrical activity is experienced in both sides of the brain, resulting in more severe and widespread effects for the body.
Unknown onset - this is the most challenging type as the source is unidentifiable, the treatment course is much more challenging.
So why do seizures occur? The brain is built up of neurons which are purposed to transfer messages throughout the brain and body, through electrical impulses. For this to be effective, the neurons need to act together in some kind of order. If you think about a large meeting, nothing will be communicated if everybody speaks at once. But this is exactly what happens during a seizure; a large group of neurons will send messages simultaneously, which is known as hypersynchrony. This disrupts brain functionality and can spike changes in taste, vision, sound, smell, language, movement, emotion, and consciousness.
Although it hasn’t been fully established how, extensive research has shown that CBD has a dramatic effect in reducing epeleptic seizures. A meta-analysis took 670 people with varying cases of epilepsy and gave them full spectrum CBD over the course of a year. At the end of the observation 40% of participants saw their seizures halved, a quarter had a 70% drop, and 10% were seizure free by the end.1
