Peace and health to all

I'm writing because I need help! For the last three years my formally healthy husband has been experiencing partial and grand-mal seizures. Over the past three months he started experiencing what doctors call non-epileptic seizures, which caused him to have excrutiating pain at the base of his neck and on the left side of his body. My husband started having these seizures at the age of 49 after he had several root canals done. We had the root canals removed by a highly qualified doctor in New York but the seizures have continued albeit at a slower pace. After reviewing his family history we found out that his father, sister and half-brother had a history of aneurysms. Now we're trying to have his health provider give him an MRA, he's already had an MRI,CT and every other test you can imagine. At one point they said that his non-epileptic seizures were pyscho-psomatic but since learning of his family history they've agreed to look at some other things. He's been a vegan vegetarian for the past thirty years but does consume brown Sugar and honey. Has anyone else experienced this? Are there any suggestions as to where we should look? He went on an extensive cleanser after the 1st seizure 3 years ago and lost a lot of waste. But we still don't have any answers and are very skeptical of the traditional medical community. Help!!
