I'm so happy that you found this new neuro!!! I hope it works out for you.
Did you have an EEG or an EKG? An EKG is for the heart and EEG is for brain activity. An EEG would show, as long as you get in a deep enough sleep, seizure activity. Is that what you had done?
The cane is a good idea. I got tired of falling all the time. The cane does help. I had to use it daily for a while but now only use it if I am walking longer distances (more than 50 to 100 ft.). In the stores, I use the scooter. It's the only way I can make it through a shopping trip and still have some physical as well as cognitive functioning to drive back home. And, once I caught on to the scooter trick, I don't have to leave the store within 5 - 10 minutes of being there.
Let us know the results of your testing and how you are doing.
