Please look up schizophrenia and the connection to brainwashing victims.
(Unfortunately it is difficult to sort through real information vs forum posts written by schizophrenics whose minds are attempting to blame imaginary targets because they cannot determine the real cause.)
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.
