Related question: In the show Babylon Berlin, you can see plenty of comments about returning soldiers who have tremors (possibly from shell shock). There seems to be derision about the state of those men. Was this an accurate portrayal of German attitude to shell shocked soldiers at the time?

According to War of Nerves by Ben Shephard, German treatment of what the British called 'shell shock' tended to emphasise 'treatments' that were quite cruel, but like the other powers such injuries were so new and unknown that soldiers could receive radically different treatment depending on whom was providing the therapy. Max Nonne was a Hamburg therapist who saw these symptoms as a wartime version of existing neuroses, and he employed hypnotherapy. However, 'authoritarian pressure' was more common with 'the main method being electrotherapy'. A leading practitioner of the method, Kaufman, admitted his treatments left soldiers 'no longer suitable at ball for service in the field' and was 'inappropriate for officers'.

By 1918 these treatments, which by then had killed over 20 patients, were questioned in the Reichstag, forcing the head of the German Army's medical services to defend the treatment regime.

Shephard points out that other aspects of German treatment of psychological casualties were more humane than the British (and French): they executed fewer men, were more willing to accept that casualties could not be returned to front-line service, and they often provided better specialist care, sooner.
