One aspect that I remember well: therapists and nurses would use euphemisms. They would say a particular patient was "not able" to do what is expected. How does personal responsibility fit in to such thinking?
I also remember the "occupational therapy", which in my case comprised working in a lab with cancer patients' urine samples. The "occupational therapist" talked about learning the discipline to stay with repetivie tasks. That shows in the movie, as Marie is rewarded for being able to work increasingly long days as a clerk, but still sometimes sees demons in the typewriter.
Picture: above: NIH Clinical Center, Bethesda, MD, where I was a "patient" in 1962.
