By "crazy action" I mean for 2 years wilfully undereating, not washing, living in filth, not responding to basic communication (even to your own daughter) and standing for long stretches of time at road intersections.
>And under what mental disorder should someone be institutionalised?
Under those that are responsible for causing a person to suffer and damage their own health and fail to try to recover, or seek help with recovery, as in the example above.

No, wasn't aware. I use them interchangeably.
