“…Growing evidence from both human behavioral and neuroimaging studies suggest that ED is a trans-diagnostic risk factor as well as the treatment and intervention foci across many mental disorders including ADHD and BD, although it is not included as a formal diagnostic criterion in DSM-5 (American Psychiatric Association, 2013; Carmassi et al, 2022; Kebets et al, 2021; Lenzi et al, 2018). Such as, consistent findings demonstrated that both ADHD and BD patients reported higher ED level and preferred to adopt more maladaptive ER strategies compared to healthy controls (Beheshti et al, 2020; De Prisco et al, 2022; Minò, 2022; Miola et al, 2022; Oliva et al, 2023; Shaw et al, 2014; Soler-Gutiérrez et al, 2023). On the other hand, some other studies show that while BD group exhibited higher scores on affective instability than ADHD group (Richard-Lepouriel et al, 2016; Sesso et al, 2021), ADHD group scored higher on emotional intensity (Richard-Lepouriel et al, 2016; Torrente et al, 2017).…”
