Thank you all for responses and replies once I wrote regarding our son. After the video/telemetry study at the University Hospital and we learned his seizures were psychogenic non epileptic, we next quizzed his doctors regarding a possible change up on his medications. In fact, he was keenly interested himself. After all, he is the individual living this illness picture from the inside.

Thus, we engaged with Doctor's consent and participation in a titrative migration from the set of meds then being used to control psychosis to another med. Interestingly, his seizures are seeming to abate and some emotive display has been restored, a better life than the flatness he was displaying.

Maybe, maybe we are on a right path.
All for now,
