Hello @grecarmar I am Scott and while not any kind of medical professional, I can relate what we encountered with this definition when my wife was battling many of her dementia-like symptoms due to her brain cancer. Many of her symptoms were extreme and quite different than what had been witnessed in somewhat similar patients.

In our case I found the term behavioral unit and psychiatric unit were often used interchangeably. In my wife's case this would have been a unit within an acute care hospital where they would work intensively to take her off every medication she was on and then slowly build back up as they observed how each medication worked or didn't for her. She did not enter this unit as her main neuro doctor felt it would be better for her (and me as her caregiver) to continue to work on balancing her medicinal cocktail to achieve the desired results. Again, this was just our experience with this area of medicine.

I don't know if this helps at all or not.

Strength, courage, and peace
