So yeah..."Sensory Tremens"...why?

I'm...confused why they made up a human mental disorder in Voyager. Its not as bad as when they made up an Indigenous tribe for Chakotay, but there's actual real world conditions and disorders that match what Chakotay had.

It kinda reeks of "We thought it'd be too offensive if we gave it a real name" but instead it just comes off as odd.

NINETIES STAR TREK-watch 3 great episodes in a row, and then see one scene where its like "Why the hell did they do this?"
