Jeavons is a tough one unfortunately. It can be treated but it is not like epilepsy. Can take a long time to find the balance of medication and removal of external stimulate. I'm sorry you are going through this. The brain is always trying to protect itself and many times it overproduces neurotransmitters to try and "fix itself". Like the unknowns of epilepsy it is always hard to find out why. Get a good neurologist and work with them.

No, but apparently they come together, like anxiety and OCD. Totally different, but just an example.

My daughter was just diagnosed this week.
