The basic principle behind psychiatric genetics is that genetic polymorphisms (as indicated by linkage to e.g. a single nucleotide polymorphism) are part of the causation of psychiatric disorders. [1] Psychiatric genetics is a somewhat new name for the old question, "Are behavioral and psychological conditions and deviations inherited?".
The Journal of Genetic Psychology: Research and Theory on Human Development is a quarterly peer-reviewed scientific journal covering developmental psychology.The first scholarly journal devoted to the field of developmental psychology, it was established in 1891 by G. Stanley Hall as The Pedagogical Seminary, and was renamed The Pedagogical Seminary and Journal of Genetic Psychology in 1924.
Epigenetics of anxiety and stress–related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more.
In 2024, Douglas Wahlsten wrote that the contents of the journal are "thoroughly modern", not suffering from the genetic determinism that "infected" many earlier behavior-genetics publications. [ 1 ] According to the Journal Citation Reports , its 2023 impact factor is 2.4, ranking the journal 195th out of 310 journals in the category ...
The theory behind cognitive genomics is based on elements of genetics, evolutionary biology, molecular biology, cognitive psychology, behavioral psychology, and neurophysiology. Intelligence is the most extensively studied behavioral trait. [1] In humans, approximately 70% of all genes are expressed in the brain. [2]
Classified as a "conversion disorder" by the DSM-IV, a psychogenic disease is a condition in which mental stressors cause physical symptoms matching other disorders. The manifestation of physical symptoms without biologically identifiable cause results from disruptions in normal brain function due to psychological stress.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
