“…Cognitive functioning in schizoaffective disorder is much less studied compared with schizophrenia; yet, a meta-analysis of the available data that directly compared cognitive functioning across schizophrenia, schizoaffective disorder and affective psychosis did not provide evidence for categorical differences between schizophrenia and other groups, in line with recent findings from genetic studies which have reignited the debate about the validity of Kraepelin's classification of the major psychoses (Bora et al, 2009b). It would be also important to study whether there are significant differences in attentional performance in psychotic disorders over other severe mental illnesses such as bipolar disorder (e.g., Addington and Addington, 1997;Bozikas et al, 2005).…”

A B S T R A C TPsychotic disorders are some of the most severe psychiatric conditions. Patients have difficulties in identifying facial expressions and appear to be highly sensitive to the presence of emotional distractors. Yet, no study has investigated whether perceptual load modulates the interference of emotional distractors. Our goal was to test whether psychotic patients were more sensitive to irrelevant emotional stimulus, even when the task demands a high amount of attentional resources. Twenty-two participants with schizophrenia or schizoaffective disorder and twenty-two healthy controls, performed a target letter discrimination task with emotional task-irrelevant stimulus (angry, happy and neutral facial expressions). Target-letters were presented among distrator-letters, which could be similar (low perceptual load) or different (high load); participants should discriminate the target-letter and ignore the facial expression. Results showed that patients were more prone to distraction by task-irrelevant stimulus, especially under high load, suggesting difficulties in attention control. Moreover, in psychotic patients, happy faces caused higher interference with the task, whereas neutral and angry faces resulted in less interference. These findings could provide innovative approaches regarding attentional deficits on social contexts in patients with schizophrenia spectrum disorders.

“…Moreover, there are documented similarities between these patient groups with respect to pattern of cognitive function, suggesting that any mediation may hold across diagnoses; studies have demonstrated impairment in executive functioning, attention and memory in both patients with schizophrenia (Addington et al, 2005;Nathaniel-James et al, 1996;Wang et al, 2005) and depression Porter et al, 2003). Finally, as in other studies (for example, Bozikas et al, 2005;Harvey et al, 2004) this pilot study did not consider the possible influence of psychotropic medications on cognitive functioning. Tricyclic antidepressants may impair cognitive and psychomotor function (Lane & O'Hanlon, 1999), antipsychotic medications may cause psychomotor slowing (Palmer & Heaton, 2000) and impair reaction times (Blyler & Gold, 2000), and newer anti-psychotic medications can cause fatigue (Gothelf et al, 2003).…”

“…Schizophrenia and depression are associated with a variety of cognitive impairments, particularly in the domains of memory, attention and executive functioning (Addington et al, 2005;Bozikas et al, 2005;Egeland et al, 2000;Fossati et al, 1999;Harvey et al, 2004;Keefe et al, 2004;Manoach et al, 2005;Nathaniel-James et al, 1996;Porter et al, 2003). Similar deficits have been demonstrated in both disorders (e.g.…”

There is evidence for a deleterious effect of maternal mental illness on motherinfant interaction. Presence of mental illness and lowered maternal cognitive function independently predict quality of interaction, but their combined effect on interaction is unclear. A pilot study was conducted to explore the relationship between maternal serious mental illness (SMI), cognitive function, and mother-infant interaction. Six mothers with SMI (two with schizophrenia and four with depression) and 12 mothers with no psychiatric history were recruited, together with their infants (all aged between 5 and 18 weeks). Mother-infant

“…For instance, attentional and executive impairments were found both in patients with schizophrenia and in their unaffected first-degree relatives, suggesting that they might be considered as familial vulnerability markers [31][32][33][34]. Likewise, sustained attention was found to be impaired in individuals suffering from schizophrenia as well as their close relatives, and therefore, it has been proposed as a genetic vulnerability marker, or/and an endophenotype of schizophrenia [35][36][37]. On the other hand, according to the Distress/Protection Vulnerability model, quality of life impairment is also related to the vulnerability to schizophrenia [3,13,30].…”

Predicting quality of life impairment in chronic schizophrenia from cognitive variables

This study suggests that deficits in executive functioning, attention, memory and motor skills substantially contributes to predicting impairments across a wide range of HRQL domains, and, consequently, to quality of life appraisal in schizophrenia. Cognitive predictors cannot be attributed to illness-related and background variables. It can be concluded that, when aiming at the improvement of quality of life in schizophrenia patients, cognitive functioning should be targeted.
