Integrative cognitive remediation for early psychosis: A 12-month follow-up.

In recent years, a growing number of studies have attempted to treat social-cognitive impairment within neurocognitive remediation as means of improving outcome in psychotic disorders with promising results. However, the durability of the effects is still under debate and little is known about the long-term efficacy of integrated neuro- and social-cognitive remediation in early psychosis. The purpose of this study was to examine long-term effects of a 12-week integrative cognitive remediation (ICR) for early psychosis. Thirty-seven patients diagnosed with primary psychotic disorder and previously treated with ICR as part of their standard treatment were assessed on cognitive performance, psychopathology, and functional outcome at baseline, 3 months (posttest) and 12 months (follow-up). After participating in ICT, individuals showed significant improvements on most neurocognitive and social cognitive domains. A significant increase in number of participants employed was found at 12-month. The study suggests ICR may have favorable effect on long-term cognitive improvements and functional gains in early psychosis.

Facilitating the Delivery of Cognitive Remediation in First-Episode Psychosis: Pilot Study of a Home-Delivered Web-Based Intervention.

We explored the adherence to a home-delivered, computer-based, cognitive remediation protocol in a first-episode psychosis outpatient cohort. Seventeen patients underwent a cognitive training protocol for 6 months using an online platform accessible from their home under the supervision of a qualified neuropsychologist. Neuropsychological, psychopathological, and functional data were collected at baseline and postintervention, whereas qualitative appraisal of the intervention was assessed monthly. Overall, participants' evaluation of the program was positive. This was reflected in a good adherence rate with 12 (70%) of 17 patients completing 80% of the prescribed sessions. Exploratory analysis revealed significant improvements in sustained attention (p = 0.020) and verbal memory (p = 0.018). A decrease in negative symptoms and an improvement on the Clinical Global Impression were also found (p = 0.009). We believe these are encouraging results to further explore the adopted delivery approach, which could facilitate access to cognitive training earlier and to a larger group of patients.

Psychological interventions in psychosis in children and adolescents: a systematic review.

BACKGROUND: Early onset psychosis (EOP), referring to psychosis with onset before the age of 18 years, is a more severe form of psychosis associated with worse prognosis. While medication is the treatment of choice, psychological interventions are also considered to have an important role in the management of symptoms and disability associated with this condition. The present review aimed to explore the effectiveness of such interventions. METHOD: An electronic search was conducted on the Embase, Medline, and PsychInfo databases for papers of randomized controlled trials (RCTs) referring to psychological interventions in EOP. References of identified papers were hand searched for additional studies. Identified studies were quality assessed. RESULTS: Eight studies were included in the present review evaluating cognitive remediation therapy (CRT), cognitive behavioural therapy (CBT), a family intervention and psychoeducation. CRT was associated with improvement in cognitive function and CBT and CRT seem to also have a positive effect in psychosocial functioning. Symptom reduction appears to not be significantly affected by the proposed treatments. CONCLUSIONS: There is some evidence supporting the effectiveness of psychological interventions in EOP. However, most research on adolescents is focused on CRT and its effects on cognitive deficits. More studies on the effects of psychological interventions in EOP are needed.

Neurorrehabilitación cognitiva: fundamentos y aplicaciones de la musicoterapia neurológica / Cognitive neurorehabilitation: the foundations and applications of neurologic music therapy

Introducción. El conocimiento de la plasticidad cerebral y los numerosos estudios con neuroimágenes de los últimos años han permitido un avance en la comprensión del proceso cerebral de los estímulos musicales. Ello ha propiciado el interés para analizar y estudiar su aplicación en el tratamiento no invasivo de determinadas disfunciones o enfermedades con el fin de contribuir a una mejora de la calidad de vida. Objetivo. Exponer los fundamentos y aplicaciones de las técnicas musicales que se utilizan para la neurorrehabilitación cognitiva. Desarrollo. A partir de un resumen inicial del proceso cerebral de los estímulos musicales, se exponen los fundamentos de diversas técnicas, tal como define la musicoterapia neurológica, que se utilizan de forma eficaz en la neurorrehabilitación cognitiva. Los sonidos, que constituyen la materia prima de la música, mantienen una temporalidad y una secuenciación que son útiles para ayudar a la formación de patrones temporales de las funciones cognitivas y conforman un ensamblaje o armazón que facilita el aprendizaje de los procesos secuenciales de información, como por ejemplo, la memoria. Conclusiones. Las técnicas usadas por la musicoterapia neurológica, que en los últimos años se aplican en la neurorrehabilitación cognitiva, no son invasivas y aportan resultados esperanzadores; con una mayor investigación, deberían considerarse para su implantación junto a las terapias convencionales de estimulación y neurorrehabilitación cognitiva

Introduction. Music is the result of a perception in the brain involving a number of cortical and subcortical areas in both brain hemispheres. Increased knowledge about brain plasticity and the numerous neuroimaging studies conducted in recent years have made it possible to further our understanding of the processing of musical stimuli in the brain. This has led to an interest in analysing and studying its application in the non-invasive treatment of certain dysfunctions or diseases with the aim of helping to achieve an improved quality of life. Aim. To outline the foundations and applications of the musical techniques that are used in cognitive neurorehabilitation. Development. Following an initial summary of the processing of musical stimuli in the brain, the study goes on to explain the foundations of different techniques, as defined by neurologic music therapy, that are used efficaciously in cognitive neurorehabilitation. Sounds, which are the raw material of music, maintain a temporality and a sequencing that are a useful aid in the formation of temporal patterns of the cognitive functions, and constitute an assembly or framework that facilitates the learning of sequential information processing, such as memory. Conclusions. The techniques used in neurologic music therapy, which in recent years are being applied for cognitive neurorehabilitation, are not invasive and offer promising results that, together with further research, should be taken into account to be implemented alongside the conventional therapies of cognitive neurorehabilitation and stimulation

Long term neurocognitive improvement after "late" right hemispherectomy: case report and review of the literature.

OBJECTIVE: To study the long-term neurocognitive changes of a right-handed girl with intractable epilepsy after late right hemispherectomy and compare them with data in the literature. METHOD: The girl was affected by an epileptic encephalopathy associated with right fronto-temporo-parietal polymicrogyria; she was submitted to right hemispherectomy at the age of 5 and examined with cognitive and neuropsychological tests at the age of 17 years. The girl took advantage of neurocognitive rehabilitation for several years; she is currently seizure-free and off therapy. RESULTS: At the end of the follow-up, the full-scale IQ is stable and within the normal range (p = 88). As the discrepancy between verbal IQ (pp = 120) and performance IQ (pp = 71) is significantly high, the girl was subjected to neurocognitive evaluation with the following results: verbal problem solving, verbal short- and long-term memory, and executive functions are within normal range. The most fragile functional areas are visual and spatial reasoning, verbal working memory, short-term visuospatial memory, visual attention, and processing speed, all > 2 SD. The spatial tests, such as coding, matrix reasoning, picture concepts, and arithmetic reasoning (which are favored by other functions such as associative memory and learning ability), are less severely impaired. CONCLUSIONS: These findings show that good conceptual skills and verbal reasoning can compensate for some deficits in visual-perceptual and visuospatial functions.

Cognitive remediation improves executive functions, self-regulation and quality of life in residents of a substance use disorder therapeutic community.

BACKGROUND: Executive dysfunction is common in substance use disorder (SUD) populations and hinders treatment. We previously found that 50% of residents in SUD therapeutic communities had been hospitalized for head injuries; this was a significant determinant of cognitive impairment. The current study aimed to establish whether cognitive remediation improves executive functions (EFs) and self-regulation in an ecologically valid sample of female residents attending SUD therapeutic community treatment, including those with past head injuries and psychiatric comorbidities. METHODS: Controlled sequential groups design with residents (N=33, all female) receiving treatment as usual (TAU). The intervention group (n=16) completed four weeks of cognitive remediation (CR) and the control, TAU only (n=17). Outcome measures assessed pre- and post-intervention included both performance- and inventory-based measures of EFs, and self-reported self-regulation and quality of life. RESULTS: CR relative to TAU significantly improved performance-based assessment of inhibition (Color-Word Interference Test; F=4.29, p=0.047), inventory-based assessment of EFs (Behavior Rating Inventory of Executive Function - Adult Version: Global Executive Composite; F=6.38, p=0.017), impulsivity (Barratt Impulsiveness Scale; F=4.61, p=0.040), self-control (Brief Self-Control Scale; F=5.53, p=0.026), and quality of life (Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form; F=7.68, p=0.010). CONCLUSIONS: Findings suggest that CR improves EFs in a heterogeneous sample of female residents in therapeutic community SUD treatment. Future research may explore the possibility of tailoring CR interventions for various SUD subgroups.
