How can one induce psychogenic death? I saw something about psychogenic death. I am wondering if it can be induced by a desire. I think that it can by a person being lazy and not caring about the world. It is said to happen with prisoners of war. The article says that it is not suicide but I don't know if it is true. It cannot happen all at once, it just happens because the person does not care.
There is an article here: https://www.eurekalert.org/pub_releases/2018-09/uop-pcd092018.php

Leach's hypothesis is based upon case reports of prisoners of war subject to the most severe forms of incarceration and profound deprivation.  A minority of prisoners reportedly completely withdrew and ceased any form of goal directed behaviour (eating, drinking etc.).  Presumably, the prisoner's 'giving up' was in response to their self-evaluation that survival was impossible in the circumstances.
