“…An increased prevalence of alexithymia, relative to rates observed in the general population, is also seen in neurological conditions including Multiple Sclerosis (Chahraoui et al, 2008), Parkinson's Disease (Costa, Peppe, Carlesimo, Salamone, & Caltagirone, 2010), and following traumatic brain injury (TBI) (Henry, Phillips, Crawford, Theodorou, & Summers, 2006;Wood & Williams, 2007), providing evidence of "acquired alexithymia" following presumed typical development. Alexithymia has been found to increase the likelihood of a number of other socio-emotional deficits, including difficulties recognising emotions from both faces (Cook, Brewer, Shah, & Bird, 2013;Grynberg et al, 2012; although see McDonald et al, 2011) and voices (Heaton et al, 2012), reduced levels of empathy (Bird et al, 2010), and difficulties regulating one's own emotion (Pandey et al, 2011). Alexithymia is also associated with impaired learning and decision-making (Bibby & Ferguson, 2011;Ferguson et al, 2009;Kano, Ito, & Fukudo, 2011), increased self-harm (Norman & Borrill, 2015), and negatively impacts the effectiveness of most psychotherapy (Lumley, Neely, & Burger, 2007;Mccallum, Piper, Ogrodniczuk, & Joyce, 2003).…”
