Predictive Genetic Testing for Neurodegenerative Conditions: How Should Conflicting Interests Within Families be Managed?
Zornitza Stark et al.
Predictive genetic testing for a neurodegenerative condition in one individual in a family may have implications for other family members, because it can reveal their genetic status.The authors argue that while it may not be possible to completely avoid harm in these situations, it is important to consider the magnitude of risks and make every effort to limit the potential for adverse outcomes.
Effect of Public Deliberation on Attitudes Toward Return of Secondary Results in Genomic Sequencing
Michele C. Gornick et al.
This study suggests that education and deliberation enhance public appreciation of the scientific and ethical complexities of genome sequencing, which is important to the formation of ethical guidelines regarding secondary findings.
Neuroscience in Forensic Psychiatry: From Responsibility to Dangerousness. Ethical and Legal Implications of Using Neuroscience for Dangerousness Assessments
Georgia Martha Gkotsi and Jacques Gasser
This paper argues that the introduction of neuroscientific data by forensic experts into criminal trials will be mostly be used in the future as a means to evaluate or assess an offender's dangerousness, rather than responsibility.
True Grit and Genetics: Predicting Academic Achievement From Personality
Kaili Rimfeld, Yulia Kovas, Philip S. Dale, and Robert Plomin
Grit—perseverance and passion for long-term goals—has been shown to be a significant predictor of academic success, even after controlling for other personality factors. The authors conclude that the etiology of grit is highly similar to other personality traits, not only in terms of its substantial genetic influence but also in showing no influence of shared environmental factors.
A Review of Vulnerability and Risks for Schizophrenia: Beyond the Two Hit Hypothesis.
Justin Davis et al.
The development of schizophrenia is likely to be more complex and nuanced than the binary “two hit” (genetic predisposition combined with environmental factors) model originally proposed nearly 30 years ago. Risk appears influenced by a more complex process involving genetic risk interfacing with multiple potentially interacting factors.
Brain White Matter Structure and COMT Gene are Linked to Second-Language Learning in Adults
Ping Maimiya et al.
This study shows that genetic factors influence second-language learning in adults, and that grades in a language learning program are best predicted by measures of brain connectivity and COMT genotype.
Physical and Neurobehavioral Determinants of Reproductive Onset and Success
Felix Day et al.
The ages of puberty, first sexual intercourse, and first birth signify, respectively, the onset of reproductive ability, behavior, and success, and genetic factors influence the timing of those milestones.
Mosaic Loss of Chromosome Y in Blood is Associated with Alzheimer Disease
Jan P. Dumanski et al.
In order to shed light on the factors underlying the shorter life expectancy of men vs. women, the authors tested the hypothesis that the loss of chromosome Y in blood cells would render men more susceptible to Alzheimer disease (AD), and found that such a loss is associated with risk of both AD and cancer.
