Open Access Peer-reviewed Research Article David M. Greenberg , Simon Baron-Cohen, Nora Rosenberg, Peter Fonagy, Peter J. Rentfrow Published: October 3, 2018 https://doi.org/10.1371/journal.pone.0203886 Abstract Traumatic events increase the risk of depression, but there is also evidence that adversity can lead to posttraumatic growth, including increased compassion and prosocial behavior.

Although somewhat counter-intuitive, this might be predicted if trauma not only increases fear…

Hommer, Reza Momenan Published: November 18, 2013 https://doi.org/10.1371/journal.pone.0080952 Abstract Many brain imaging studies have demonstrated reductions in gray and white matter volumes in alcoholism, with fewer investigators using diffusion tensor imaging (DTI) to examine the integrity of white matter pathways. Among various medical conditions, alcoholism and post-traumatic stress disorder (PTSD) are two comorbid diseases that have similar degenerative effects on the white matter integrity. Therefore, understanding and…

Baumgartner, Christoph Eisenegger, Matthias Vonmoos Published: March 2, 2017 https://doi.org/10.1371/journal.pone.0172853 Abstract Chronic cocaine use has been associated with impairments in social cognition, self-serving and antisocial behavior, and socially relevant personality disorders (PD).
