There are 2 major authoritative references of mental disorders. Those references are the DSM and the ICD. The classification systems of the 2 manuals are nearly identical, such that the 2 manuals may be collectively called DSM/ICD. 'DSM' is an abbreviation for 'diagnostic and statistical manual of mental disorders'. ICD is an abbreviation for 'international classification of diseases'. The DSM is produced by a committee within the American Psychiatric Association (APA). The ICD is produced by the World Health Organization (WHO).
Each disorder listed in the DSM/ICD is designated by a number, most often with a number or numbers after a decimal point. Disorders that begin with the number 301 are personality disorders.
301.20 is schizoid personality disorder, 301.21 is introverted personality disorder, and 301.22 is schizotypal personality disorder. Introverted personality disorder is listed in the ICD manual but not the DSM manual. The listing of introverted personality as a personality disorder is a blatant act of persecution of a character type.
The diagnostic descriptions of schizoid and schizotypal personality disorders also serve as persecution, by falsely portraying people of a specific character as being similar to schizophrenics.
There are such disorders as schizoid personality disorder and schizotypal personality disorder, but their descriptions in the DSM/ICD manual are inaccurate, such that they falsely associate the true disorders with character traits that are unrelated. Schizotypal personality disorder is often considered a type of schizoid personality disorder, but with additional symptoms.
True schizoid personality disorder is characterized by a negative symptom of schizophrenia, from which the term 'schizoid' derives. Namely, they are characterized by a general lack of motivation and capacity for pleasure. As an effect of this, schizoid people have little facial expression. Social interaction is merely one of the pleasures that a schizoid lacks; there is no specific lack of capacity for pleasure from social interaction that is more pronounced than the lack of capacity for other pleasures. A true schizoid typically has average to below average intelligence. A true schizoid is more likely than the average person to have a genetic relative(s) that is schizophrenic.
True schizotypal personality disorder is characterized by a general desire for excitement, combined with a willingness to deceive oneself. That causes a person to belief things that are exciting but illogical, and sometimes egomaniacal. That tendency to jump to belief without scrutiny resembles the positive symptoms of schizophrenia, in which a person's brain fabricates sensations and beliefs without restraint. It is from that that the term 'schizotypal' derives. As a result of a schizotypal person's beliefs and egomania, such a person is likely to act in an unusual way that is a reflection of those beliefs and egomania. A true schizotypal person is more likely than the average person to have a genetic relative(s) that is schizophrenic.
A pseudoschizoid contrasts with those descriptions. A pseudoschizoid desires independence and secrecy, due to seeing the fundamental truth that different beings are separate and defined. The average pseudoschizoid only has somewhat less overall capacity for pleasure than the average person, and has no less motivation than the average person. A pseudoschizoid has less capacity for social pleasure, but has MORE capacity for the pleasure of beauty. A pseudoschizoid's typical facial expression is not quite the same as the typical facial expression of a schizoid. A schizoid's typical facial expression is entirely blank, with no muscle contractions. A pseudoschizoid's typical facial expression has slight contraction of the corrugator supercilii (which scrunches the eyebrows) and the obicularis oculi (which squints the eyes). A pseudoschizoid's beliefs, ideals, and behaviors, are more rightful than those of the status quo, which are wrongful. A pseudoschizoid does not hold any beliefs because they are exciting or egomaniacal, as schizotypal people do. A pseudoschizoid typically has high intelligence. A pseudoschizoid is no more likely than the average person to have a genetic relative(s) that is schizophrenic.
The DSM/ICD description of schizoid personality disorder vastly over-emphasizes the non-social aspect of schizoid personality disorder, such that people that have pseudoschizoid character can be falsely classified as having the disorder.
The DSM/ICD description of schizotypal personality disorder uses excessively broad terms to describe schizotypal personality disorder, such that any person that has uncommon beliefs, ideals, and/or behaviors can be falsely classified as having the disorder.
Additionally, there is a clever trick in the description of schizotypal personality disorder. People with said disorder are said to believe that they are being persecuted. That is a method of circular logic. If a person points out that that is a fraudulent diagnosis done for the purpose of persecution, then the behavior of making that observation is covered by the description of schizotypal personality disorder itself.
Pseudoschizoids have weak serotoninergic neurotransmission, and are therefore vulnerable to post-SSRI sexual dysfunction (PSSD), which is a permanent loss of capacity for physical sexual pleasure after taking SSRIs.
