The risk notably increases after age 65. Dementia leads to a progressive decline in cognitive functions, affecting memory, reasoning, and problem-solving abilities. This decline can impact the individual's ability to perform daily tasks and make decisions, underscoring the crucial importance of timely identification. With the advent of technologies like computer vision and deep learning, the prospect of early detection becomes even more promising. Employing sophisticated algorithms on imaging data, such as positron emission tomography scans, facilitates the recognition of subtle structural brain changes, enabling diagnosis at an earlier stage for potentially more effective interventions. In an experimental study, the Swin transformer algorithm demonstrated superior overall accuracy compared to the vision transformer and convolutional neural network, emphasizing its efficiency.

In this study, we aimed to determine pathogenic variants in a family with HSP, which was not diagnosed through conventional genetic testing. We clinically characterized a large family and conducted whole genome sequencing (WGS) analysis of four affected and three unaffected individuals in the family to identify the genetic cause of HSP.

First, schizophrenia is clearly a hereditary disease. Second, however, schizophrenia is not the hereditary trait itself but rather the consequences of a slowly developing biological progress, the nature of which remains entirely unknown. Third, the full manifestation of the disorder requires certain environmental influences that must come into play. In around 30% of cases, the environment can inhibit hereditary factors so that the predisposition does not manifest in schizophrenia. Fourth, the mode of inheritance of schizophrenia remains unknown, although recessivity is more likely than dominance and monomerism is more likely than polymerism. Fifth, current evidence suggests that schizophrenia is likely etiologically homogenous. Sixth, schizophrenia is part of a hereditary circle that includes “normal” variants of the human personality (schizothymia), a pathological version of this dimension (schizoidia), and other schizophrenia-like delusional syndromes. Luxenburger is skeptical of efforts to clarify further Mendelian transmission models in the absence of pathophysiological markers because schizophrenia cannot serve as a typical phenotype for genetic analysis. By contrast, he strongly supports empirical work on hereditary prognosis, which does not depend on assumptions about any particular phenotype–genotype relationship.</p>","PeriodicalId":7673,"journal":{"name":"American Journal of Medical Genetics Part B: Neuropsychiatric Genetics","volume":"195 6","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajmg.b.32977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140139789","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}
