Rachel Anderson had hit a breaking point. Her son was diagnosed with a rare form of epilepsy called Lennox-Gastaut syndrome at age 4. Then when he was 6, he got diagnosed with autism spectrum disorder (ASD).

“We had tried six or seven pharmaceutical drugs,” she told Healthline, explaining their attempts to get his seizures under control. “None of them worked, or if they did, they had serious side effects that made life miserable for all of us.”

Those side effects included intense rages. “He would attack me, my husband, his brother, who was only 4 at the time. And he’s a big kid. When he was 6, he weighed 100 pounds.”

Deanna Weatherman can relate. Her son also has epilepsy and is on the ASD spectrum. They too had tried numerous medications, only to be left feeling underwhelmed and frustrated by the results.
