No evidence of volume reductions in the hippocampus or amygdala was found. Comparison between the female-only subsamples (48 BPD patients and 37 controls) yielded similar findings. The cluster of volume reduction in the left TPJ continued to be seen in 37 drug-na\u00efve patients.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291725101645_sec4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>According to this study, the initial stage of BPD is characterized by decreased grey matter volume in the left TPJ, a region that is implicated in various aspects of social cognition. Given that the volume loss was detected prior to adulthood, in individuals without comorbidities, and among patients who were drug na\u00efve, this finding could be significant for understanding the developmental trajectory of the disease.<\/jats:p>\n
