Would you please enlighten me? I've spent a lot of time researching schizophrenia and I've never come across anything that would suggest it's inflictable.
Malicious mind control techniques (gaslighting, etc) can cause a victim to doubt themselves, damaging the psyche, causing paranoia, and leading to a psychotic state, sometimes semi-permanent. The mind needs to resolve some issues and without doing so it will accumulate cognitive dissonance. Mania induced by these psychotic states can actually cause physical damage to the brain.
It is not known exactly what causes schizophrenia but it is known that it can be the consequence of these sort of psychological stressors, i.e. people lose their shit and have breakdowns when they get too emotionally damaged.
