Psychiatric terminology was changed recently. Some pschiatric terms have been dropped such as paranoia and schizophrenia. However, some technical terms are still considered valid. The definitions may have been changed, slightly. However, the words are still clinically formal. For example, Asperger's syndrome and psychotic personality are still valid terms. 1) What is the clinical difference, if any, between Asperger's syndrome and a psychotic personality? Specific questions. 2) Suppose supervisors find out that an employee has been diagnosed with Asperger's syndrome. Are they justified in thinking that he is likely to be violent or pathologically aggressive? 3) Suppose supervisors find out that an employee has been diagnosed with psychotic personality. Are they justified in thinking that he is likely to be violent or pathologically aggressive? Both Aspergers and psychosis is associated with "lack of empathy". 4) Is the "lack of empathy" clinically the same in both Aspergers and psychosis? These questions are important. I know of a TV police program in which the serial killer was diagnosed with "Aspergers syndrome". The next day, employees with "Aspergers syndrome" were basically harassed "for the safety of others". To be fair, this was a few months after one of those high school shootings. A student who was diagnosed as "psychotic" came to school and started to shoot everybody up. So everyone was tense as to "psychotics". However, it got associated with Aspergers syndrome. Maybe this was justified and maybe not. Supervisors are supposed to keep watch over possible signs of trouble. If the two syndromes are different, there should be nearly objective ways to distinguish between them.
