“…In an attempt to explore the potential of the abovementioned dysconnectivity as a biological marker for BPD, it is recommended that future studies should also carry out functional connectivity analyses in the most commonly documented comorbidities of BPD, which are MDD, attention deficit hyperactivity disorder (ADHD), and PTSD. PTSD is of particular interest given that both BPD and PTSD are highly related to experiences of trauma (Zetzsche et al, 2006;Pagura et al, 2010;Philipsen et al, 2010;Stein et al, 2010), and many common neurobiological abnormalities have been identified between the two (O'Neill et al, 2013). Although MDD was the only comorbidity that was allowed in our BPD sample, which increased the homogeneity of the sample, this in itself may limit the generalisability of the findings given the high occurrence of other/additional comorbidities found in the wider population of individuals with BPD.…”
