Schizoid Man (comics) , a character from Marvel Comics 21st Century Schizoid Man ,
160-773: A class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting , one or more hydrogen atoms in the amphetamine core structure with substituents . The compounds in this class span a variety of pharmacological subclasses, including stimulants , empathogens , and hallucinogens , among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine , ephedrine , cathinone , phentermine , mephentermine , tranylcypromine , bupropion , methoxyphenamine , selegiline , amfepramone (diethylpropion) , pyrovalerone , MDMA (ecstasy), and DOM (STP). Some of amphetamine's substituted derivatives occur in nature, for example in
240-619: A Moscow hospital found that schizoid individuals were the least common patients, while those with cluster B personality disorders were the most common. A study that looked at the body mass index (BMI) of a sample of both male adolescents diagnosed with SzPD and those diagnosed with Asperger syndrome found that the BMI of all patients was significantly below normal. Clinical records indicated abnormal eating behavior by some patients. Some patients would only eat when alone and refused to eat out. Restrictive diets and fears of disease were also found. It
320-635: A close relative on occasions. They usually prefer hobbies and activities that do not require interaction with others. People with SzPD may be averse to social situations due to difficulties deriving pleasure from physical or emotional sensations, rather than social anhedonia . One potential motivation for avoiding social situations is that they feel that it intrudes on their freedom. Relationships can feel suffocating for people with SzPD, and they may think of them as opportunities for entrapment. Patients with this disorder are often independent and turn to themselves as sources of validation. They tend to be
400-420: A combination of cognitive-behavioral therapy and psychodynamic psychotherapy . These techniques can be used to help patients identify their defense mechanisms and change them. Therapists attempt to establish healthy relationships with their clients, helping to combat their internalized belief that relationships are harmful and unhelpful. Relationships with a therapist can seem terrifying and intrusive to
480-847: A concept. He identified four subtypes of SzPD. Any schizoid individual may exhibit none or one of the following: American psychoanalyst Salman Akhtar provided a comprehensive phenomenological profile of SzPD in which classic and contemporary descriptive views are synthesized with psychoanalytic observations. This profile is summarized in the table reproduced below that lists clinical features that involve six areas of psychosocial functioning and are organized by "overt" and "covert" manifestations. "Overt" and "covert" are intended to denote seemingly contradictory aspects that may both simultaneously be present in an individual. These designations do not necessarily imply their conscious or unconscious existence. The covert characteristics are by definition difficult to discern and not immediately apparent. Additionally,
560-544: A constitutional, probably genetic, basis." Research on heritability and this disorder is lacking. Twin studies with SzPD traits (e.g., low sociability and low warmth) suggest that these traits are inherited. Besides this indirect evidence, the direct heritability estimates of SzPD range from 50% to 59%. Earlier, less methodologically rigorous research had found the heritability rate to be 29%. The pathophysiology of SzPD remains unclear. Genetic relationships with people who have schizophrenia spectrum disorders increase
640-450: A control group. In the 2012 study, it was noted that the DSM may complicate diagnosis by requiring the exclusion of a pervasive developmental disorder (PDD) before establishing a diagnosis of SzPD. The study found that social interaction impairments, stereotyped behaviors, and specific interests were more severe in the individuals with Asperger syndrome also fulfilling SzPD criteria, against
720-412: A deep desire to connect with others, yet will be terrified by the dangers inherent in doing so. Avoidance of social situations may be a method of avoiding being hurt or rejected. Individuals with SzPD can form relationships with others based on intellectual, physical, familial, occupational, or recreational activities, as long as there is no need for emotional intimacy. Donald Winnicott explains this
800-593: A defense mechanism to protect the patient from the outside world and its difficulties. Common themes in their internal fantasies are omnipotence and grandiosity . The related schizotypal personality disorder and schizophrenia are reported to have ties to creative thinking , and it is speculated that the internal fantasy aspect of SzPD may also be reflective of this thinking. Alternatively, there has been an especially large contribution of people with schizoid symptoms to science and theoretical areas of knowledge, including mathematics , physics , economics , etc. At
880-671: A desire to destroy or put down others. Additionally, schizoid individuals do not go out of their way to achieve social validation. Unlike narcissists, schizoid people will often keep their creations private to avoid unwelcome attention or the feeling that their ideas and thoughts are being appropriated by the public. When forced to rely on others, a person with SzPD may feel panic or terror. Patients with SzPD often feel unreal, empty, and separate from their own emotions. They tend to perceive themselves as fundamentally different from others and can believe that they are fundamentally unlikeable. Other people often seem strange and incomprehensible to
SECTION 10
#1732776089166960-524: A feeling of failure and negatively impacting their willingness to continue to commit to treatment. Clinicians tend to worry that they are incapable of properly treating the patient. It is rare for someone with this disorder to voluntarily seek treatment without a comorbid disorder or pressure from family or friends. In treatment, people with SzPD are usually disinterested and often minimize symptoms. Patients with SzPD may fear losing their independence through therapy. Many schizoid individuals will avoid making
1040-478: A hard time forming a good working relationship with a therapist. SzPD is a poorly studied disorder, and there is little clinical data on SzPD because it is rarely encountered in clinical settings. Studies have generally reported a prevalence of less than 1%. It is more commonly diagnosed in males than in females. SzPD is linked to negative outcomes, including a significantly compromised quality of life , reduced overall functioning even after 15 years, and one of
1120-755: A lack of sexual definition but rather a combination of several strong fixations to cope with the same conflicts. People with SzPD are often able to pursue any fantasies with content on the Internet while remaining completely unengaged with the outside world. Sensory or emotional experiences typically provide little enjoyment for people with SzPD. They rarely display strong emotions or react to anything. People with SzPD can have difficulty expressing themselves and seem to be directionless or passive. Individuals with SzPD can also experience anhedonia . They can also have difficulty understanding others' emotions and social cues . It can be hard for people with SzPD to assess
1200-463: A large city often considered a magnet for disenfranchised people. A University of Colorado Colorado Springs study comparing personality disorders and Myers–Briggs Type Indicator types found that the disorder had a significant correlation with the Introverted (I) and Thinking (T) preferences. Perfectionist and hypercritical parenting or cold, neglectful, and distant parenting contribute to
1280-462: A long tradition of chewing khat leaves to achieve a stimulating effect. The active substances of khat are cathinone and, to a lesser extent, cathine. Amphetamine was first synthesized in 1887 by Romanian chemist Lazăr Edeleanu , although its pharmacological effects remained unknown until the 1930s. MDMA was produced in 1912 (in 1914, according to other sources ) as an intermediate product. However, this synthesis also went largely unnoticed. In
1360-410: A lower risk of substance abuse issues than people with other personality disorders . They may form relationships with their substances as a substitute for human contact or to cope with emotional issues. People with SzPD may desire psychedelic drugs more than other kinds. Many schizoid individuals display an engaging, interactive personality, contradicting the observable characteristic emphasized by
1440-457: A medicine ( Benzedrine ) for colds and nasal congestion . Subsequently, amphetamine was used in the treatment of narcolepsy , obesity , hay fever , orthostatic hypotension , epilepsy , Parkinson's disease , alcoholism and migraine . The "reinforcing" effects of substituted amphetamines were quickly discovered, and the misuse of substituted amphetamines had been noted as far back as 1936. During World War II , amphetamines were used by
1520-407: A more distant emotional proximity. If that is true, then many of the more problematic reactions these individuals show in social situations may be partly accounted for by the judgments commonly imposed on people with this style. Similarly, John Oldham , using a dimensional approach , thinks that most people with schizoid character features do not have a full-blown personality disorder. Impairment
1600-451: A participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, all forms of asexuality , and idiosyncratic moral or political beliefs. Symptoms typically start in late childhood or adolescence. The cause of SzPD is uncertain, but there is some evidence of links and shared genetic risk between SzPD, other cluster A personality disorders , and schizophrenia . Thus, SzPD
1680-566: A person with SzPD. They may feel as if they need to alter or hide their feelings to meet the therapist's demands or expectations. To combat this, therapists try to gradually increase their patient's emotional expression. Expressing too much too early can lead to their ending therapy. Treatment must be person centered , with clients feeling understood and well regarded. This can allow them to connect with and understand their emotions. When people with SzPD do not have their feelings validated, this will confirm their belief that expressing themselves
SECTION 20
#17327760891661760-494: A person with SzPD. Reality can feel unenjoyable and uninteresting to people with SzPD. They have difficulty finding motivation and lack ambition. Patients with SzPD often feel as if they are "going through the motions" or that "life passes them by." Many describe feeling as if they are observing life from a distance. Aaron Beck and his colleagues report that people with SzPD seem comfortable with their aloof lifestyle and consider themselves observers, rather than participants in
1840-496: A potentially effective medication for SzPD. Originally, low doses of atypical antipsychotics like risperidone or olanzapine were used to alleviate social deficits and blunted affect. However, a 2012 review concluded that atypical antipsychotics were ineffective for treating personality disorders. Antidepressants , SSRIs , anxiolitics , bupropion , modafinil , benzodiazepines , and biofeedback may also be effective treatments. Treatment for this disorder uses
1920-677: A robot" or "going through life in a dream". People with SzPD may try to avoid all physical activity in order to become nobody and disconnect from reality. This can lead to the patient spending a large quantity of time sleeping and ignoring bodily functions such as hygiene . Although this disorder does not affect the patient's capacity to understand reality, they may engage in excessive daydreaming and introspection . Their daydreams can grow to consume most of their lives. Real life can become secondary to their fantasy , and they can have complex lives and relationships which exist entirely inside of their internal fantasy. These daydreams may constitute
2000-421: A schizoid disorder. Theodore Millon restricted the term "schizoid" to those personalities who lack the capacity to form social relationships. He characterizes their way of thinking as being vague and void of thoughts and as sometimes having a "defective perceptual scanning". Because they often do not perceive cues that trigger affective responses, they experience fewer emotional reactions. For Millon, SzPD
2080-452: A single personality disorder. It has also been argued due to the poor consistency and efficiency of diagnosis due to overlapping traits that SzPD should be removed altogether from the DSM. A 2012 article suggested that two different disorders may better represent SzPD: one affect-constricted disorder (belonging to schizotypal PD) and a seclusive disorder (belonging to avoidant PD). They called for
2160-417: A solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment, and apathy . Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy world . Other associated features include stilted speech , a lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than

There is no widely accepted and approved psychotherapy or medication for this disorder. It is one of the most poorly researched psychiatric disorders. Professionals may misunderstand the disorder and the client, potentially reinforcing
2480-424: Is because schizoid individuals "prefer to make relationships on their own terms and not in terms of the impulses of other people." Failing to attain that, they prefer isolation. In general, friendship for schizoid individuals is usually limited to one other person, who is often also schizoid, forming what has been called a union of two eccentrics; "within it – the ecstatic cult of personality, outside it – everything

2560-630: Is being violated, and they commonly feel that masturbation or sexual abstinence is preferable to the emotional closeness they must tolerate when having sex. Significantly broadening this picture are notable exceptions of SzPD individuals who engage in occasional or even frequent sexual activities with others. Individuals with SzPD have long been noted to have an increased rate of unconventional sexual tendencies, though if present, these are rarely acted upon. Schizoid people are often labeled asexual or present with "a lack of sexual identity". Kernberg states that this apparent lack of sexuality does not represent
2640-444: Is common amongst people with SzPD. This leads to them isolating themselves to avoid the discomfort and stimulation that emotional experiences offer. According to Guntrip , Klein, and others, people with SzPD may possess a hidden sense of superiority and lack dependence on other people's opinions. This is very different from the grandiosity seen in narcissistic personality disorder , which is described as "burdened with envy" and with
2720-432: Is considered to be a "schizophrenia-like personality disorder". It is diagnosed by clinical observation, and it can be very difficult to distinguish SzPD from other mental disorders or conditions (such as autism spectrum disorder , with which it may sometimes overlap). The effectiveness of psychotherapeutic and pharmacological treatments for the disorder has yet to be empirically and systematically investigated. This
2800-454: Is dangerous. Therapists attempt to avoid intruding on their patients' lives or restricting their freedoms, so as to prevent them from feeling as if therapy is intolerable. Because of this, therapy is usually less structured than treatment programs for other disorders. Patients may benefit from long-term treatment lasting several years. Inpatient care may be effective for treating SzPD and other Cluster A disorders. The original concept of

He criticizes that this may be due to the current diagnostic criteria: They describe SzPD only by an absence of certain traits, which results in a "deficit syndrome" or "vacuum". Instead of delineating the presence of something, they mention solely what is lacking. Therefore, it is hard to describe and research such
3040-579: Is largely because people with SzPD rarely seek treatment for their condition. Originally, low doses of atypical antipsychotics were used to treat some symptoms of SzPD, but their use is no longer recommended. The substituted amphetamine bupropion may be used to treat associated anhedonia . However, it is not general practice to treat SzPD with medications, other than for the short-term treatment of acute co-occurring disorders (e.g. depression ). Talk therapies such as cognitive behavioral therapy (CBT) may not be effective, because people with SzPD may have
3120-586: Is mandatory for any behavior to be diagnosed as a personality disorder . Ralph Klein, Clinical Director of the Masterson Institute, delineates the following nine characteristics of the schizoid personality as described by Harry Guntrip : The description of Guntrip's nine characteristics should clarify some differences between the traditional DSM portrait of SzPD and the traditional informed object relations view. All nine characteristics are consistent. Most, if not all, must be present to diagnose
3200-557: Is not involved. According to Fairbairn, the person disowns the part they are playing, and the schizoid individual seeks to preserve their personality intact and immune from compromise. The schizoid person's false persona is based on what those around them define as normal or good behavior, as a form of compliance. Further references to the secret schizoid come from Masud Khan , Jeffrey Seinfeld, and Philip Manfield. These scholars described secret schizoids as people who enjoy public speaking engagements but experience great difficulty during

It was incorporated into the DSM-III as schizoid personality disorder to describe difficulties forming meaningful social relationships and a persistent pattern of disconnection and apathy. The diagnosis of SzPD made it to the DSM-IV and DSM-V. It remains unclear how prevalent

3360-440: Is sharply rejected and despised". Their unique lifestyle can lead to social rejection and people with SzPD are at a higher risk of facing bullying or homelessness . This social rejection can reinforce their asocial behavior. People with this disorder usually have little to no interest in sexual or romantic relationships. They rarely date or marry. Sex often causes individuals with SzPD to feel that their personal space
3440-550: The DSM-5 and ICD-10 definitions of the schizoid personality. Guntrip (using ideas of Klein, Fairbairn, and Winnicott) classifies these individuals as "secret schizoids", who behave with socially available, interested, engaged, and involved interaction yet remain emotionally withdrawn and sequestered within the safety of the internal world. Klein distinguishes between a "classic" SzPD and a "secret" SzPD, which occur "just as often" as each other. Klein cautions one should not misidentify
3520-550: The United States adopted "the Controlled Substances Act" that limited non-medical use of substituted amphetamines. Street use of PMA was noted in 1972. MDMA emerged as a substitute for MDA in the early 1970s. American chemist Alexander Shulgin first synthesized the drug in 1976 and through him the drug was briefly introduced into psychotherapy. Recreational use grew and in 1985 MDMA was banned by
3600-437: The frontal lobe , amygdala , and striatum . Traumatic brain injuries to the frontal lobe may also contribute to the onset of SzPD as that area of the brain controls areas such as emotion and socialization. Deficits in the right hemisphere of the brain may also be associated with SzPD. Lower levels of low-density lipoprotein cholesterol may be correlated with the presence of schizoid traits in women. Excess indices in
3680-689: The "schizoid condition", which roughly includes the DSM schizoid, avoidant and schizotypal personality disorders, is represented by "as many as forty percent of all personality disorders." Manfield adds: "This huge discrepancy [from the ten percent reported by therapists for the condition] is probably largely because someone with a schizoid disorder is less likely to seek treatment than someone with other axis-II disorders." A 2008 study assessing personality and mood disorder prevalence among homeless people at New York City drop-in centers reported an SzPD rate of 65% among this sample. The study did not assess homeless people who did not show up at drop-in centers, and
3760-467: The "shut-in" personality. Characteristics of it were reticence, reclusiveness, shyness and a preference for living in fantasy worlds, among others. In 1925, Russian psychiatrist Grunya Sukhareva described a "schizoid psychopathy" in a group of children, resembling today's SzPD and ASD . About a decade later Pyotr Gannushkin also included Schizoids and Dreamers in his detailed typology of personality types. The descriptive tradition began in 1925 with
3840-442: The 1920s, both methamphetamine and the dextrorotatory optical isomer of amphetamine, dextroamphetamine , were synthesized. This synthesis was a by-product of a search for ephedrine, a bronchodilator used to treat asthma extracted exclusively from natural sources. Over-the-counter use of substituted amphetamines was initiated in the early 1930s by the pharmaceutical company Smith, Kline & French (now part of GlaxoSmithKline ), as

The widespread use of substituted amphetamines began in postwar Japan and quickly spread to other countries. Modified "designer amphetamines", such as MDA and PMA , have gained in popularity since the 1960s. In 1970,

In their status of isolation and emotional bluntness they can be self-sufficient and safe. Childhood trauma can also contribute to feelings of emptiness in adulthood. Alcoholism in parents is associated with a heightened risk of developing SzPD. Sula Wolff , who did extensive research and clinical work with children and teenagers with schizoid symptoms, stated that "schizoid personality has

These references expose the problems in relying on outer observable behavior for assessing the presence of personality disorders in certain individuals.

Tantam suggested that Asperger syndrome may confer an increased risk of developing SzPD. A 2019 study found that 54% of a group of males aged 11 to 25 with Asperger syndrome showed significant SzPD traits, with 6% meeting full diagnostic criteria for SzPD, compared to 0% of
4240-530: The description of observable schizoid behaviors by Ernst Kretschmer . He organized those into three groups of characteristics: These characteristics were the precursors of the DSM-III division of the schizoid character into three distinct personality disorders: schizotypal , avoidant and schizoid. Kretschmer himself, however, did not conceive of separating these behaviors to the point of radical isolation but considered them to be simultaneously present as varying potentials in schizoid individuals. For Kretschmer,
4320-452: The disorder is. It may be present in anywhere from 0.5% to 7% of the population and possibly 14% of the homeless population. Gender differences in this disorder are also unclear. Some research has suggested that this disorder may occur more frequently in men than women. SzPD is uncommon in clinical settings (about 2.2%) and occurs more commonly in males. It is rare compared with other personality disorders. Philip Manfield suggests that
4400-604: The efforts required to establish a proper relationship with the therapist. It can be difficult for them to open up or discuss their emotions in therapy. Although people with this disorder can still improve, it is unlikely they will ever experience significant joy through social interaction. SzPD is associated with a dismissive-avoidant attachment style . People with this disorder will rarely maintain close relationships and often exclusively choose to participate in solitary activities. People with schizoid personality disorder typically have no close friends or confidants, except for
4480-527: The general population. One study found that significantly fewer boys with SzPD had alcohol problems than a control group of non-schizoid people. Another study evaluating personality disorder profiles in substance abusers found that substance abusers who showed schizoid symptoms were more likely to abuse one substance rather than many, in contrast to other personality disorders such as borderline , antisocial , or histrionic , which were more likely to abuse many. American psychotherapist Sharon Ekleberry states that
4560-488: The happiest when in relationships in which their partner places few emotional or intimate demands on them and does not expect phatic or social niceties. It is not necessarily people they want to avoid, but negative or positive emotional expectations, emotional intimacy , and self-disclosure . Patients with SzPD can feel as if close emotional bonds are dangerous to themselves and others. They may have feelings of inadequacy or shame. Some people with SzPD may experience
4640-638: The impact of their actions in social situations. People with this condition are often indifferent towards criticism or praise and can appear distant, aloof, or uncaring to others. They may avoid others and expressing themselves as a method of keeping others distant and preventing themselves from being hurt. Remaining alone and expressionless can feel safe and comfortable for people with SzPD. Expressing themselves can make them feel shame or discomfort. People with SzPD may feel inadequate and can be sensitive, although they have difficulty expressing it. Alexithymia , or difficulties understanding one's own emotions,
4720-581: The impoverished social connections experienced by people with SzPD limit their exposure to the drug culture and that they have limited inclination to learn how to do illegal drugs. Describing them as "highly resistant to influence", she additionally states that even if they could access illegal drugs, they would be disinclined to use them in public or social settings, and because they would be more likely to use alcohol or cannabis alone than for social disinhibition , they would not be particularly vulnerable to negative consequences in early use. People with SzPD are at
4800-556: The lack of data on the frequency of many of the features makes their relative diagnostic weight difficult to distinguish at this time. However, Akhtar states that his profile has several advantages over the DSM in terms of maintaining historical continuity of the use of the word schizoid , valuing depth and complexity over descriptive oversimplification and helping provide a more meaningful differential diagnosis of SzPD from other personality disorders. Substituted amphetamine Substituted amphetamines , or simply amphetamines , are
4880-1390: The leaves of Ephedra and khat plants. Amphetamine was first produced at the end of the 19th century. By the 1930s, amphetamine and some of its derivative compounds found use as decongestants in the symptomatic treatment of colds and also occasionally as psychoactive agents. Their effects on the central nervous system are diverse, but can be summarized by three overlapping types of activity: psychoanaleptic , hallucinogenic and empathogenic . Various substituted amphetamines may cause these actions either separately or in combination. A variety of prodrugs of amphetamine and/or methamphetamine exist, and include amfecloral , amfetaminil , benzphetamine , clobenzorex , D -deprenyl , deprenyl , dimethylamphetamine , ethylamphetamine , fencamine , fenethylline , fenproporex , furfenorex , lisdexamfetamine , mefenorex , prenylamine , and selegiline . A number of synthetic Russian amphetamine derivatives have been developed, including alafen (amphetamine–β-alanine), feprosidnine , gamofen (amphetamine–GABA), mesocarb , methylphenatine , pabofen (amphetamine–PABA), phenatine (amphetamine–niacin; N -nicotinoylamphetamine), phenylphenamine (phenylamphetamine), propylphenamine (propylamphetamine), pyridoxiphen (amphetamine–pyridoxine), and thiophenatine ( N -thionicotinoylamphetamine).

Children with this disorder usually have poor relationships with others, social anxiety , internal fantasies, strange behavior, and hyperactivity . These behaviors can result in teasing and bullying at the hands of others. It is common for people with SzPD to have had major depressive disorder in childhood. SzPD
5040-518: The lowest levels of "life success" of all personality disorders (measured as "status, wealth and successful relationships"). Bullying is particularly common towards schizoid individuals. Suicide may be a running mental theme for schizoid individuals, though they are not likely to attempt it. Some symptoms of SzPD (e.g. solitary lifestyle, emotional detachment, loneliness, and impaired communication), however, have been stated as general risk factors for serious suicidal behavior. The term schizoid
5120-480: The majority of schizoid people are not either oversensitive or cold, but they are oversensitive and cold "at the same time" in quite different relative proportions, with a tendency to move along these dimensions from one behavior to the other. The second path, that of dynamic psychiatry, began in 1924 with observations by Eugen Bleuler , who observed that the schizoid person and schizoid pathology were not things to be set apart.

The authors believe that a substantial subgroup of people with autism spectrum disorder or PDD have clear "schizoid traits" and correspond largely to the "loners" in Lorna Wing 's classification The autism spectrum ( Lancet 1997), described by Sula Wolff . The authors of the 2019 study hypothesized that it is extremely likely that historic cohorts of adults diagnosed with SzPD either also had childhood-onset autistic syndromes or were misdiagnosed. They stressed that further research to clarify overlap and distinctions between these two syndromes
5280-492: The onset of SzPD. For a person with SzPD, their parents likely were intolerant of their emotional experiences. They may have been forced to repress and compartmentalize their emotions, possibly resulting in the onset of difficulties expressing and processing emotional experiences. These difficulties lead to the child feeling rejected and developing the belief that the only safe environment is one where they are alone and inexpressive. People with SzPD may also have internalized
5360-399: The rates of most other personality and mood disorders within the drop-in centers were lower than that of SzPD. The authors noted the limitations of the study, including the higher male-to-female ratio in the sample and the absence of subjects outside the support system or receiving other support (e.g., shelters ) as well as the absence of subjects in geographical settings outside New York City,
5440-467: The replacement of the SzPD category from future editions of the DSM with a dimensional model which would allow for the description of schizoid traits on an individual basis. Some critics such as Nancy McWilliams of Rutgers University and Panagiotis Parpottas of European University Cyprus argue that the definition of SzPD is flawed due to cultural bias and that it does not constitute a mental disorder but simply an avoidant attachment style requiring
5520-428: The risk of developing schizoid personality disorder. People with SzPD can have a history of schizotypy before developing the disorder. SzPD symptoms can be premorbid to schizophrenia. Prenatal malnutrition , premature birth , and low birth weight are all thought to play a role in the development of SzPD. SzPD is associated with reduced serotonergic and dopaminergic pathways in areas such as
5600-844: The same time, people with SzPD are helpless at many practical activities because of their symptoms. Symptoms of SzPD such as isolation and the blunted affect put people with schizoid personality disorder at a higher risk of suicide and non-suicidal self-harm . This may be because their reduced capacities for emotion prevent them from properly dealing with strife. Their solitary nature may contribute by preventing them from finding relief in relationships. Demonstrative suicides or suicide blackmail, as seen in cluster B personality disorders such as borderline , histrionic , or antisocial , are extremely rare among schizoid individuals. As in other clinical mental health settings, among suicidal inpatients, individuals with SzPD are not as well represented as some other groups. A 2011 study on suicidal inpatients at
5680-401: The schizoid character developed by Ernst Kretschmer in the 1920s comprised a mix of avoidant , schizotypal , and schizoid traits. It was not until 1980 and the work of Theodore Millon that led to splitting this concept into three personality disorders (now schizoid, schizotypal, and avoidant). This caused debate about whether this was accurate or if these traits were different expressions of
5760-402: The schizoid character, most notably from writers Nannarello (1953), Laing (1965), Winnicott (1965), Guntrip (1969), Khan (1974), Akhtar (1987), Seinfeld (1991), Manfield (1992) and Klein (1995). The DSM-I had the diagnosis of schizoid personality , which was defined by avoidance of close relationships, inability to express aggressive feelings, and autistic thinking (thinking which
5840-516: The schizoid person as a result of the patient's defensive, compensatory interaction with the external world. He suggests one ask the person what their subjective experience is, to detect the presence of the schizoid refusal of emotional intimacy and preference for objective fact. A 2013 study looking at personality disorders and Internet use found that being online more hours per day predicted signs of SzPD. Additionally, SzPD correlated with lower phone call use and fewer Facebook friends. Descriptions of
5920-406: The schizoid personality as "hidden" behind an outward appearance of emotional engagement have been recognized since 1940, with Fairbairn's description of "schizoid exhibitionism", in which the schizoid individual can express a great deal of feeling and make what appear to be impressive social contacts yet, in reality, gives nothing and loses nothing. Because they are "playing a part", their personality
6000-468: The schizoid personality, from which most of what is known today about schizoid phenomena is derived, was presented in 1940. Here, Fairbairn delineated four central schizoid themes: Following Fairbairn's derivation of SzPD from a combination of derealization , depersonalization , splitting , the oral stage of making all subjects into partial objects , and intellectualization ; the dynamic psychiatry tradition has continued to produce rich explorations on
6080-600: The terms "autism" and "schizoid" to describe withdrawal to an internal fantasy, against which any influence from outside becomes an intolerable disturbance. In a 2012 study of a sample of 54 young adults with Asperger syndrome, it was found that 26% of them also met the criteria for SzPD, the highest comorbidity out of any personality disorder in the sample (the other comorbidities were 19% for obsessive–compulsive personality disorder , 13% for avoidant personality disorder and one female with schizotypal personality disorder ). Additionally, twice as many men with Asperger syndrome met
6160-539: The world around them. But they also mention that many of their schizoid patients recognize themselves as socially deviant (or even defective) when confronted with the different lives of ordinary people – especially when they read books or see movies focusing on relationships. Even when schizoid individuals may not long for closeness, they can become weary of being "on the outside, looking in". These feelings may lead to depression, depersonalization , or derealization . If they do, schizoid people often experience feeling "like
6240-428: Was coined in 1908 by Eugen Bleuler to describe a human tendency to direct attention toward one's inner life and away from the external world. Bleuler labeled the exaggeration of this tendency the "schizoid personality". He described these personalities as "comfortably dull and at the same time sensitive, people who in a narrow manner pursue vague purposes". In 1910, August Hoch introduced a very similar concept called
6320-432: Was strongly warranted, especially given that high-functioning autism spectrum disorders are now recognized in around 1% of the population. There are no effective medications for schizoid personality disorder. However, certain medications may reduce the symptoms of SzPD and treat co-occurring mental disorders . Since the symptoms of SzPD mirror the negative symptoms of schizophrenia, antipsychotics have been suggested as
6400-452: Was suggested that the anhedonia of SzPD may also affect eating, leading schizoid individuals to not enjoy it. Alternatively, it was suggested that schizoid individuals may not feel hunger as strongly as others or not respond to it, a certain withdrawal "from themselves". Very little data exists for rates of substance use disorder among people with SzPD, but existing studies suggest they are less likely to have substance abuse problems than
