Purple,
When dealing with the medical field of various doctors etc. it is important that you learn to become your own health advocate. You cannot expect any doctor or neurologist to diagnose you without understanding all of what you experience with your brain. You should not be hiding the realities of what you struggle with, you need to be honest and make sure you relate all the issues you address. That is the only way you are going to finally get a more accurate diagnosis of what is wrong.

Not all doctors have all the necessary knowledge, I truely think your best bet is to try to get help again from a neuologist and make sure you tell him/her ALL the things you experience. Hiding facts will not help them learn to help you. Just my opinion.
