Schizoid Avoidant Behavior
The relationship between schizoid personality disorder (SPD) and avoidant personality disorder (AvPD) has been a subject of controversy for decades. Today it is still unclear and remains to be seen if these two personality disorders are genuinely distinct, but overlapping, personality disorders, or if they are merely two different phenotypic expressions of the same underlying disorder. Both have been associated with a shared genetic risk factor and the same polymorphism within the ANKK1 gene. There is also some evidence that AvPD (like SPD) is a personality disorder of the schizophrenia spectrum. Originally, schizoid personality disorder involved social avoidance combined with marked ambivalence regarding the desirability of social contact. It included indifference or even cold disdain oscillating with longing for normal relationships. Through the efforts of Theodore Millon Theodore Millon () (August 18, 1928 – January 29, 2014) was an American psychologist known for his wor ...

Schizoid Personality Disorder
Schizoid personality disorder (, often abbreviated as SzPD or ScPD) is a personality disorder characterized by a Asociality, lack of interest in social relationships, a tendency toward 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 (psychology), fantasy world. Other associated features include stilted speech, a Anhedonia, lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than a participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, a degree 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, ...

Avoidant Personality Disorder
Avoidant personality disorder (AvPD) is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy (despite an intense desire for it), severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli (e.g. self-imposed social isolation) as a maladaptive coping method.''Anxious voidant personality disorder' in ICD-10Diagnostic Criteria anClinical descriptions and guidelines. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women. People with AvPD often avoid social interaction for fear of being ridiculed, humiliated, rejected, or disliked. They typically avoid becoming involved with others unless they are certain they will not be rejected, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenotypic
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and then again in his 1982 book ''The Extended Phenotype'' suggested that one can regard bird nests and other built structures such as caddis ...

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANKK1
Ankyrin repeat and kinase domain containing 1 (ANKK1) also known as protein kinase PKK2 or sugen kinase 288 (SgK288) is an enzyme that in humans is encoded by the ''ANKK1'' gene. The ANKK1 is a member of an extensive family of the Ser/Thr protein kinase family, and protein kinase superfamily involved in signal transduction pathways. Clinical significance This gene contains a single nucleotide polymorphism that causes an amino acid substitution within the 11 of 12 ankyrin repeats of ANKK1 (Glu713Lys of 765 residues). This polymorphism, which is commonly referred to Taq1A, was previously believed to be located in the promoter region of the DRD2 gene, since the polymorphism is proximal to the DRD2 gene and can influence DRD2 receptor expression. It is now known to be located in the coding region of the ANKK1 gene which controls the synthesis of dopamine in the brain. The A1 allele is associated with increased activity of striatal L-amino acid decarboxylase. A1+ allele * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizophrenia Spectrum Disorders
A spectrum disorder is a mental disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and trait theory, traits. The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism. In either case, a spectrum approach is taken because there appears to be "not a unitary disorder but rather a syndrome composed of subgroups". The spectrum may represent a range of severity, comprising relatively "severe" mental disorders through to relatively "mild and nonclinical Cognitive deficit, deficits". In some cases, a spectrum approach joins conditions that were previously considered separately. A notable example of this trend is the autism spectrum, where conditions on this spectrum may now all be referred to as autism spectrum disorders. A spectrum approach may also expand the type or the severity of issues which are included, which may lessen the gap with other diagnoses or with ...

Ambivalence
Ambivalence is a state of having simultaneous conflicting reactions, beliefs, or feelings towards some object. Stated another way, ambivalence is the experience of having an attitude towards someone or something that contains both positively and negatively valenced components. The term also refers to situations where "mixed feelings" of a more general sort are experienced, or where a person experiences uncertainty or indecisiveness. Although attitudes tend to guide attitude-relevant behavior, those held with ambivalence tend to do so to a lesser extent. The less certain an individual is in their attitude, the more impressionable it becomes, hence making future actions less predictable and/or less decisive. Ambivalent attitudes are also more susceptible to transient information (e.g., mood), which can result in a more malleable evaluation. However, since ambivalent people think more about attitude-relevant information, they also tend to be more persuaded by (compelling) attitude-rel ...

Theodore Millon
Theodore Millon () (August 18, 1928 – January 29, 2014) was an American psychologist known for his work on personality disorders. He founded the ''Journal of Personality Disorders'' and was the inaugural president of the International Society for the Study of Personality Disorders. In 2008 he was awarded the Gold Medal Award For Life Achievement in the Application of Psychology by the American Psychiatric Association and the American Psychological Foundation named the "Theodore Millon Award in Personality Psychology" after him. Million developed the Millon Clinical Multiaxial Inventor, worked on the diagnostic criteria for Passive-Aggressive Personality Disorder, worked on editions of the Diagnostic and Statistical Manual of Mental Disorders, and developed subtypes of a variety of personality disorders. Biography Millon was born in Brooklyn in 1928, the only child of immigrant Jewish parents from Lithuania and Poland. His 19th-century ancestors came from the town of Valozhyn, th ...

Counterdependency
Counterdependency is the state of refusal of attachment, the denial of personal need and dependency, and may extend to the omnipotence and refusal of dialogue found in destructive narcissism, for example. Developmental origins The roots of counterdependency can be found in the age-appropriate negativism of two-year-olds and teens, where it serves the temporary purpose of distancing one from the parental figure As Selma Fraiberg put it, the two-year-old "says 'no' with splendid authority to almost any question addressed to him...as if he establishes his independence, his separateness from his mother, by being opposite". Where the mother has difficulty accepting the child's need for active distancing, the child may remain stuck in the counterdependent phase of development because of developmental trauma. In similar fashion, the teenager needs to be able to establish the fact of their separate mind to their parents, even if only through a sustained state of cold rejection; and agai ...
