That awful! Your husband been through a lot of test, so here is another one - measure brain activity EEG.
After my Neurologist tried several tests, the latest is EEG. My brain didn't have any issues during the in hospital test (60min), I'm now scheduled for the Ambulatory EEG 72 hour test - " This lets you go about your normal day while a small recorder tracks brain activity for one or more days."
"An electroencephalogram (EEG) is a non-invasive, painless diagnostic test that records the electrical activity of the brain using small metal discs called electrodes attached to the scalp. The procedure is completely safe, involves no radiation or electricity transmission, and typically lasts between 20 to 60 minutes, though extended monitoring can last up to 72 hours."
Cleveland Clinic has a paper here
