Psychomotor performance and sequence planning in anorexia nervosa before and after weight restoration

Abstract

AN patients seem to show a fast response style combined with good sequence planning capacity.

Cognitive improvement following weight gain in patients with anorexia nervosa: A systematic review

“…The 24 reports included in the review (see Table 1) represented 21 different studies as the reports by Pieters et al (Pieters et al, 2004(Pieters et al, , 2005(Pieters et al, , 2006 were based on the same study sample, as were the two reports by Bühren et al (Buehren et al, 2011(Buehren et al, , 2012).…”

“…Nine studies (equivalent to 10 reports) included children and adolescents (Buehren et al, 2011(Buehren et al, , 2012Firk et al, 2015;Grunwald et al, 2001;Hatch et al, 2010;Lozano-Serra, Andrés-Perpiña, Lázaro-García, & Castro-Fornieles, 2014;Neumarker, Bzufka, Dudeck, Hein, & Neumarker, 2000;Sarrar et al, 2011;Telleus et al, 2016;Zwipp et al, 2014). Five studies included adolescents and adults (Ball, Mitchell, Touyz, Griffiths, & Beumont, 2004;Decker, Figner, & Steinglass, 2015;Epstein et al, 2001;Moser et al, 2003;Pieters et al, 2004Pieters et al, , 2005Pieters et al, , 2006. One study included children, adolescents, and young adults (Ritschel et al, 2015), while six studies did not report age range or target population (Bodell et al, 2014;Cavedini et al, 2006;Foerde & Steinglass, 2017;Koyama et al, 2012;Steward et al, 2016;Tchanturia et al, 2004).…”

“…Out of the 24 reports included, 15 (representing 12 studies) presented results in relation to practice effects either by examining the change in performance on a control group measured twice (n ¼ 14) or with reference to test-retest reliability of the cognitive test used (n ¼ 1; Moser et al, 2003) (Figure 2). Of these 15 reports, 11 detected practice effects in the cognitive tests used (Buehren et al, 2011;Buhren et al, 2012;Decker et al, 2015;Foerde & Steinglass, 2017;Lozano-Serra et al, 2014;Moser et al, 2003;Pieters et al, 2004Pieters et al, , 2005Pieters et al, , 2006Sarrar et al, 2011;Telleus et al, 2016), where three of them used alternative measurements at follow-up in a parallel design (Buehren et al, 2011;Lozano-Serra et al, 2014;Moser et al, 2003). The four studies that did not detect any practice effect used alternative measurements at follow-up (Cavedini et al, 2006;Epstein et al, 2001;Firk et al, 2015;Hatch et al, 2010).…”

“…In contrast, the literature did not indicate that psychomotor speed improved after weight gain in patients with AN. This was examined in only two studies (four reports), however, and they included different age groups (Pieters et al, 2004(Pieters et al, , 2005(Pieters et al, , 2006Sarrar et al, 2011). This finding could imply a difference in the cognitive functions controlling processing speed and psychomotor speed.…”

Unraveling Psychomotor Slowing in Bipolar Disorder

“…These methods have been found to be objective and reliable in the investigation of psychomotor activity and have been used in other major psychiatric disorders, including major depressive disorder (MDD) [13,14,15,16], anorexia nervosa [17,18], alcohol dependence [19], and schizophrenia [7,20,21]. …”
