New Definition of Epilepsy, How can they call it a Disease????

I can't believe what I read and people are going to let it be allowed! Epilepsy is not and never will be a disease! It is a medical issue in your brain caused by genetic issues, brain injury, or some un know issue as in my case, but for no possible definition is it a disease! It cannot be spread to others, it cannot be caught by a virus or bug, or prevented by a shot, pills, vacinnes! Where on this planet did a doctor come up with this definition! How can people possibly support this way to define Epilepsy! I am dissapointed to say the Least!
