2019, Journal de Therapie Comportementale et CognitiveNeural correlates of planning performance in patients with schizophrenia - Relationship with apathy
2015, Schizophrenia ResearchCitation Excerpt :While there was a non-significant relation between longer reaction times and more apathy, other studies have shown decreased performance on executive tasks in patients scoring high on apathy (Faerden et al., 2009; Konstantakopoulos et al., 2011; Roth et al., 2004). Morris et al. (1995) have suggested that quick responses of schizophrenia patients may lead to a lower performance, and that accuracy may increase with a forced longer planning time. In our study, apathy may impose longer planning times, observed as less solved trials by patients, that compensate for a lower accuracy that would otherwise be observed in patients with high levels of apathy.
Functional magnetic resonance brain imaging of executive cognitive performance in young first-episode schizophrenia patients and age-matched long-term cannabis users
2015, Neurology Psychiatry and Brain ResearchCitation Excerpt :TOL performance predominantly engages the prefrontal cortex.32–34 Previous studies have demonstrated poor TOL performance in patients with frontal brain lesions,35–38 frontal lobe dementia,39 and schizophrenia.38,40–42 Dagher and colleagues43 used this task in the Single Photon Emission Tomography (SPECT) environment to measure regional cerebral blood flow (rCBF) dependent activation to task complexity in healthy subjects, which was defined as the number of moves required to solve a TOL problem.

2013, NeuropsychologiaCitation Excerpt :Our previous report suggested that pantomime was generally associated with the FAB (Walther et al., 2013), but this result is now exclusively refined to pantomimes of meaningless gestures. We suggest that this specific deficit in gesture performance reflects the well-established impairment in planning complex actions in schizophrenia (Grootens et al., 2009; Morrens, Hulstijn, Van Hecke, Peuskens, & Sabbe, 2006; Morris, Rushe, Woodruffe, & Murray, 1995). Poor nonverbal communication skills are a well established finding in schizophrenia (Brune, Abdel-Hamid, Sonntag, Lehmkamper, & Langdon, 2009; Lavelle et al., in press; Toomey et al., 2002; Troisi et al., 1998).
