“…We focus our review on four of the most prevalent psychiatric disorders: depression (herein referred to as DEP), including major depression (MD)(Kessler et al, 2007) and dysthymia (Wittchen et al, 1994); anxiety (herein referred to as ANX), including generalized anxiety disorder (GAD) (Barlow and Wincze, 1998), posttraumatic stress disorder (PTSD)(Kessler et al, 1995), panic disorder (PD) (Kircanski et al, 2009), separation anxiety (SAD) (Shear et al, 2006), social phobia (Ruscio et al, 2008), agoraphobia (Curtis et al, 1998), obsessive compulsive disorder (OCD) (Grant et al, 2004), and overanxious disorder (OAD) (Manassis, 2000); conduct disorder (CD) (Petitclerc and Tremblay, 2009), antisocial personality disorder (ASPD) (Grant et al, 2004); opposition defiant disorder (ODD)(Grant et al, 2004); attention deficit hyperactivity disorder (ADHD) (Biederman, 2005); and substance use/abuse (SU/SA), including alcohol (Hasin et al, 2007), tobacco (Breslau et al, 2001) and drug abuse/dependence (Warner et al, 1995). According to the National Comorbidity Survey (NCS), 28.8% of the US population suffered from an anxiety disorder sometime in their life, while 20.8% suffered from a mood disorder, 14.6% engaged in SA and 9.5% presented symptoms of CD (Kessler et al, 2005).…”
