The belief in "Mentally-Ill Monsters" goes back much further than the Trump Era. There was a time in America when anyone with a simple "Neurosis" was sent away and kept locked up until they were "cured" (if ever). There were many different neuroses: obsessive–compulsive disorder, obsessive–compulsive personality disorder, impulse control disorder, anxiety disorder, hysteria, and a great variety of phobias.
According to C. George Boeree, professor emeritus at Shippensburg University, the symptoms of neurosis may involve:
• Anxiety, sadness or depression, anger, irritability, mental confusion, low sense of self-worth, et cetera.
• Behavioral symptoms such as phobic avoidance, vigilance, impulsive and compulsive acts, lethargy, et cetera.
• Cognitive problems such as unpleasant or disturbing thoughts, repetition of thoughts and obsession, habitual fantasizing, negativity and cynicism, et cetera.
Interpersonally, neurosis involves dependency, aggressiveness, perfectionism, schizoid isolation, socio-culturally inappropriate behaviors, et cetera.
The term is no longer used by the professional psychiatric community in the United States, having been eliminated from the Diagnostic and Statistical Manual of Mental Disorders in 1980 with the publication of DSM III.
