I'll say:
a) When a person doesn't know who he or she is, not for a long time, but forever.
b) Eats feces regularily.
c) Lives in self inflicted pain without knowing they are doing it.
d) There are more, but mediquitis aguditis is preventing me to remember more.

Two examples:

1- A man was carrying more than 80 pounds on each shoulder each day and every day.
I offered him a hundred bucks for the saks to rid him of his pain, and he named my moma.
Then, right away, he invited me to his farm. A hill almost impossible to climb without gear, owned by the goverment.

2- A Haitan woman that spent many ours in a bus stop wrapped in a blanket, head and all, crying out her lungs.
I don't get emotional easy. But that was the first time some event broke my heart.
And the first and last time I've called the pigs.
Their reply: " Oh she does it every day. She's not in danger, or dangerous. Let her be."

If that has another name, please, let me know.
Let me add that, at the time I didn'yt know I had any illneses
