“…Bipolar disorder (BD) is a severe and chronic mental disorder responsible for high morbidity and disability, characterized by alternation of depressive and hypomanic/manic/mixed mood episodes. Besides mood episodes, bipolar patients frequently have comorbid problems, such as anxiety disorders (ADs) (Nabavi, Mitchell, & Nutt, 2015;Sasson, Chopra, Harrari, Amitai, & Zohar, 2003;Saunders, Fitzgerald, Zhang, & McInnis, 2012;Shah et al, 2017;Simon et al, 2004;Vázquez, Baldessarini, & Tondo, 2014;Yapici Eser et al, 2018), substance use disorders (Gold et al, 2018), obsessive-compulsive disorder (OCD) (de Filippis et al, 2018), attention-deficit/hyperactivity disorder (ADHD) (Marangoni, De Chiara, & Faedda, 2015;Perroud et al, 2014), borderline personality disorder (BPD) (Frias, Baltasar, & Birmaher, 2016) and eating disorders (Alvarez Ruiz & Gutierrez-Rojas, 2015; Balzafiore et al, 2017;Brietzke, Moreira, Toniolo, & Lafer, 2011). Comorbidity is so common in BD, it is commonly contended that it would be better considered the rule rather than the exception (Sasson et al, 2003).…”
