Important contribution
The authors of an accompanying commentary noted that, despite “remarkable progress in the past 3 decades, the etiology of antisocial behavior remains elusive” (Lancet Psychiatry. 2020 Feb 17. doi: 10.1016/S2215-0366[20]30035-3).
This study makes “an important contribution by identifying structural brain correlates of antisocial behavior that could be used to differentiate among individuals with life-course-persistent antisocial behavior, those with adolescence-limited antisocial behavior, and non-antisocial controls,” write Inti A. Brazil, PhD, of the Donders Institute for Brain, Cognition and Behavior, Radboud University, Nijmegen, the Netherlands, and Macià Buades-Rotger, PhD, of the Institute of Psychology II, University of Lübeck, Germany.
They noted that the findings might help to move the field closer to achieving the long-standing goal of incorporating neural data into assessment protocols for antisocial behavior.
The discovery of “meaningful morphologic differences between individuals with life-course–persistent and adolescence-limited antisocial behavior offers an important advance in the use of brain metrics for differentiating among individuals with antisocial dispositions.
“Importantly, however, it remains to be determined whether and how measuring the brain can be used to bridge the different taxometric views and theories on the etiology of antisocial behavior,” Dr. Brazil and Dr. Buades-Rotger concluded.
The study was funded by the U.S. National Institute on Aging; the Health Research Council of New Zealand; the New Zealand Ministry of Business, Innovation and Employment; the U.K. Medical Research Council; the Avielle Foundation; and the Wellcome Trust. The study authors and the authors of the commentary disclosed no relevant financial relationships.
