Grassmann was critical of many of the highly speculative extant theories. Second, he reviewed most of the major methodologic concerns in the literature from what kinds of heredity to investigate to the problems with the global use of insanity as a diagnostic category. Third, he discussed in detail genetic theories associated with Degeneration theory, maintaining considerable skepticism. Fourth, he recognized nongenetic contribution to familial transmission. Fifth, he reviewed evidence for both homogeneous and heterogeneous transmission of forms of mental illness in families, suggesting that both were important. Sixth, while he noted that mania, melancholia, and cyclothymia commonly replaced each other in families, Verrücktheit (delusional psychoses) rarely co-segregated in families with these mood disorders. Seventh, Grassmann, like other 19th century writers, saw relatives to be of value only in assessing the level of hereditary predisposition in patients and had limited appreciation of the need for controlled studies.</p>","PeriodicalId":7673,"journal":{"name":"American Journal of Medical Genetics Part B: Neuropsychiatric Genetics","volume":"192 3-4","pages":"41-52"},"PeriodicalIF":2.8,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajmg.b.32925","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9334835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to further clarify the influence of genetic factors on associations between childhood psychopathology and adult outcomes by accounting for these correlations. Using a multivariate multivariable regression, we analyzed associations of childhood attention-deficit/hyperactivity disorder (ADHD), internalizing, and social problems, with polygenic scores (PGS) of adult disorders and traits including major depression, bipolar disorder, subjective well-being, neuroticism, insomnia, educational attainment, and body mass index (BMI), derived for 20,539 children aged 8.5–10.5 years. After correcting for correlations between the adult phenotypes, major depression PGS were associated with all three childhood traits, that is, ADHD, internalizing, and social problems. In addition, BMI PGS were associated with ADHD symptoms and social problems, while neuroticism PGS were only associated with internalizing problems and educational attainment PGS were only associated with ADHD symptoms. PGS of bipolar disorder, subjective well-being, and insomnia were not associated with any childhood traits. Our findings suggest that associations between childhood psychopathology and adult traits like insomnia and subjective well-being may be primarily driven by genetic factors that influence adult major depression.
