Which when it leads to abuse it's saving face and when it's incompetence it's saving face.

For a competent doctor it's used too let a patient know they're doing their job and an acknowledgement of symptoms.

Unfortunately to a _lot_ of the field "catch-all" "diagnoses" (in intentionally separating these labels). It's the same as diagnosing someone with chronic fatigue. It's diagnosing via exclusion.

The difference between chronic fatigue and brain disorders being that you're more likely to get someone looking to make a "name for themselves" diagnosing or curing the latter vs the former...
