Genetic<unk>  is widely understood to be a "schizophrenia spectrum" disorder. Rates of<unk>  are much higher in relatives of individuals with schizophrenia than in the relatives of people with other mental illnesses or in people without mental illness. Technically speaking,<unk>  may also be considered an "extended phenotype" that helps geneticists track the familial or genetic transmission of the genes that are implicated in schizophrenia pathogenesis. But there is also a genetic connection of STPD to mood disorders and depression in particular. Social and environmental There is now evidence to suggest that parenting styles, early separation, trauma/maltreatment history (especially early childhood neglect) can lead to the development of<unk>  traits. Neglect or abuse, trauma, or family dysfunction during childhood may increase the risk of developing<unk> . Over time, children learn to interpret social cues and respond appropriately but for unknown reasons this process does not work well for people with this disorder.<unk> s are characterized by a common attentional impairment in various degrees that could serve as a marker of biological susceptibility to STPD. The reason is that an individual who has difficulties taking in information may find it difficult in complicated social situations where interpersonal cues and attentive communications are essential for quality interaction. This might eventually cause the individual to withdraw from most social interactions, thus leading to asociality.
