Epilepsy is a neurological disorder resulting in seizures that originate in the brain. Approximately 3.4 million people nationwide have epilepsy. The intensity and frequency of seizures varies from person to person. Some are mild, while others can be more debilitating, or even fatal. Some people are born with epilepsy. For others, it can develop over time. Epilepsy can also be triggered by illness or injury. Today, there is an increasing amount of research on the potential benefits of using cannabis to reduce seizures.
