Studying the effectiveness of neurocognitive remediation in schizophrenia

Impact de la remédiation cognitive dans la schizophrénie sur les stratégies de résolution de problèmes et l’autonomie sociale : utilisation du logiciel REHACOM®

INTRODUCTION

Despite recent developments, the impact of pharmacotherapy on social autonomy and interpersonal problem solving skills in patients with schizophrenia remains limited, with consequences in terms of socio-professional functioning. Indeed, independently of the positive, negative and/or disorganization symptoms, functional deficits in patients with schizophrenia rely mainly on various cognitive impairments.

OBJECTIVES

To determine the impact of a new Cognitive Remediation Strategy on interpersonal problem solving skills, social autonomy and symptoms in patients with schizophrenia.

METHODS

Thirty patients with schizophrenia were enrolled in a program consisting of 14 training sessions of 4 cognitive functions (attention/concentration, topological memory, logical reasoning, executive functions) using the REHACOM software. Measurements of attention (Continuous Performance Test, CPT), memory (Rivermead Behavioural Memory Test, RBMT) and executive functions (Wisconsin Card Sorting Test, WCST) as well as interpersonal problem solving skills (Assessment of Interpersonal Problem-Solving Skills, AIPSS) and social autonomy (Social Autonomy Scale, EAS) and finally schizophrenia symptoms (Positive And Negative Syndrom Scale, PANSS) were undertaken at the beginning and the end of the 14 remediation meetings.

RESULTS

Cognitive functions, interpersonal problems solving skills, social autonomy and symptoms were significantly improved by the Cognitive Remediation Strategy.

CONCLUSION

Our results confirm the therapeutic impact of a Cognitive Remediation Strategy among 30 schizophrenic patients stabilised on clinical, therapeutic and functional levels. The question of the long-term maintenance of such improvements still requires further investigation.

The Status of Empirical Support for Treatments of Attention Deficits

Deficits in attention and self-regulation are common complaints associated with a number of disorders across the lifespan. The need to address attentional deficits is based on the premise that attention is a precursor and prerequisite to information processing and related cognitive tasks as well as a key factor in the success of other rehabilitation efforts. Many treatment programs have been developed with the intention of restoring or rehabilitating the impaired components of attention; the number and variety of attention programs is increasing rapidly. The purpose of this article is to evaluate available empirical support regarding the efficacy of treatments for remediation of attention deficits across disorders and age levels. The search of the major databases yielded 83 studies that included treatment of attentional deficits. Empirical studies were reviewed and categorized by the type of trial, whether or not the study included a control group, and the nature of the control group. The methodology and results of each study were then rated. For each treatment identified, the aggregated studies were then considered by the disorder of the samples included in the studies. Results indicated that, regardless of the treatment program or population, the existing research does not provide sufficient evidence to reach any conclusions about the efficacy of programs designed to address attention deficits. Before any conclusions, positive or negative, can be drawn, there is a need for more rigorous study of available treatment programs across age levels and disorders, with sufficient baseline and outcome data as well as control or alternative treatment conditions.
