genetic mental disorders

researchers have discovered that five major mental disorders may be linked to the same common inherited genetic variations, according to a study published in the journal nature genetics. previous research from the group reported the first link between the disorders, revealing that people with these disorders were more likely to have variation within the same four chromosomal sites. the researchers analyzed genetic variation in thousands of people with each of the five disorders, and compared the genetic codes with those of people who did not have the conditions. results of the analysis showed the following overlaps in heritability between particular psychiatric disorders as a result of common genetic variation: overall, the researchers found that common genetic variation accounted for between 17-28% of risk of all five disorders.

bruce cuthbert, director of the national institute of mental health, says: “such evidence quantifying shared genetic risk factors among traditional psychiatric diagnoses will help us move toward classification that will be more faithful to nature.” the researchers note that although the study results “attach numbers” to molecular evidence showing the importance of heritability linked to common genetic variation that causes these five psychiatric disorders, much of the inherited genetic contribution to these disorders is unexplained, as are non-inherited genetic factors. “it is encouraging that the estimates of genetic contributions to mental disorders trace those from more traditional family and twin studies. the study points to a future of active gene discovery for mental disorders.” a new study emphasizes the ways in which transgender and nonbinary youths benefit from access to ‘life-saving’ gender-affirming hormone therapy. in this feature, we investigate the neuroscience and psychology of hate, and potential ways to prevent it. for medical news today’s in conversation podcast for may, we delve into research on the future of mental health, with a focus on psychedelics and… lemonaid health offers online mental health treatment and prescrption delivery.

genetic mutations, polymorphisms or epigenetic changes (that will be discussed below) can alter the development of the brain in a way that changes the typical wiring of the brain. like bipolar disorder, having a first-degree relative with the disorder drastically increases the risk of developing schizophrenia later in life – though environmental factors are also incredibly important. perhaps the most widely known genetic cause of schizophrenia is disc1 (disrupted in schizophrenia 1), identified in a scottish family who had schizophrenia and subsequently other families including in america.
