Testing a Novel Web-Based Neurocognitive Battery in the General Community: Validation and Usability Study.

BACKGROUND: In recent years, there has been increased interest in the development of remote psychological assessments. These platforms increase accessibility and allow clinicians to monitor important health metrics, thereby informing patient-centered treatment. OBJECTIVE: In this study, we report the properties and usability of a new web-based neurocognitive assessment battery and present a normative data set for future use. METHODS: A total of 781 participants completed a portion of 8 tasks that captured performance in auditory processing, visual-spatial working memory, visual-spatial learning, cognitive flexibility, and emotional processing. A subset of individuals (n=195) completed a 5-question survey measuring the acceptability of the tasks. RESULTS: Between 252 and 426 participants completed each task. Younger individuals outperformed their older counterparts in 6 of the 8 tasks. Therefore, central tendency data metrics were presented using 7 different age bins. The broad majority of participants found the tasks interesting and enjoyable and endorsed some interest in playing them at home. Only 1 of 195 individuals endorsed not at all for the statement, "I understood the instructions." Older individuals were less likely to understand the instructions; however, 72% (49/68) of individuals over the age of 60 years still felt that they mostly or very much understood the instructions. CONCLUSIONS: Overall, the tasks were found to be widely acceptable to the participants. The use of web-based neurocognitive tasks such as these may increase the ability to deploy precise data-informed interventions to a wider population.

The Effects of Prescribed Physical and Cognitive Exercise on Life Satisfaction, Self-Efficacy and Mood States in Adults with Down Syndrome: The MinDSets Study.

Down syndrome (DS) is characterised by a duplication of chromosome-21 and is linked to co-occurring physical and mental health conditions, including low self-efficacy and disturbed mood states. The purpose of this study was to investigate the effects of an eight-week prescribed physical and/or cognitive training intervention on measures of mood disturbance, life satisfaction and self-efficacy in a population of adults with DS. Eighty-three participants (age 27.1 ± 8.0 years) from across five continents volunteered. Participants were assigned using matched groups based upon performance in a modified six-minute walk test to either an exercise (EXE) 3 × 30 min of walking/jogging per week, cognitive training (COG) 6 × 20 min per week, a combined group (COM) or the control (CON) who did not complete any intervention. Profile of Mood States (POMS) were assessed using a five-point scale across 65 categories pre- and post-study as well as upon completion of each week of the intervention. In addition, Satisfaction with Life Scale (SWLS) and self-efficacy using the Generalised Self-Efficacy scale (GSE) were recorded before and after the intervention. GSE increased for all participants by 1.9 ± 5.2 (p = 0.002) from pre- to post-intervention, while POMS showed significant changes for the whole group from pre- to post-intervention for tension (p < 0.001), depression (p < 0.001) and for anger (p < 0.001). In addition, significant correlations were observed between SWLS and ΔTMD, Δtension, Δanger, and Δfatigue (p < 0.05) for EXE. Both COG and EXE provide a framework for empowering enhancements in life satisfaction, self-efficacy and mood states fostering improvements in quality of life.

Acceptability of computerized cognitive training and global cognitive stimulating-based games delivered remotely: Results from a randomized controlled trial to address cancer and cancer-related cognitive impairment in breast cancer survivors.

BACKGROUND: Although the cancer-related cognitive impairment (CRCI) is a common symptom incurred by the breast cancer survivors (BCS), more emphasis is needed in identifying acceptable interventions for survivors. PURPOSE: The purpose of this qualitative descriptive study was to examine the acceptability of cognitive programs by identifying the facilitators and barriers for implementing computerized cognitive training (BrainHQ) and computerized global cognitive stimulating-based games (e.g., computerized word-find, puzzles, etc.) comparator delivered remotely to improve CRCI from the perspective of BCS. METHODS: BCS (n = 35) who enrolled and completed a randomized controlled trial of computerized cognitive training: 19 cognitive training (BrainHQ) and 16 global cognitive stimulating-based games (crosswords, puzzles, etc.) were interviewed post-training. Semi-structured questions were used, recorded, and transcribed verbatim. Qualitative data were analyzed using standard content analytic procedures for each intervention. RESULTS: Facilitators of training varied by intervention with cognitive training seen as challenging, engaging, and gave a sense of accomplishment whereas global stimulating games were seen as a way of taking mind off issues, enjoyable, and easy to navigate. Barriers of cognitive training included an awareness of failing whereas global stimulating games were deemed to be too repetitive. Both groups endorsed the convenience/flexibility of online training and common concerns of time constraints and fatigue to complete the training. Each group also provided recommendations for improvement. CONCLUSIONS: Cognitive training and global stimulating games were generally well received by BCS. Designing more support elements to promote engagement may be key to successful long-term implementation.

Principles of neuroplasticity-based rehabilitation.

The purpose of this review is to summarize how our perspective about the neuroscience of brain plasticity, informed by perceptual, experimental, and cognitive psychology, has led to the designs of a new class of therapeutic tools developed to drive functionally distorted and damaged brains in corrective directions. How does neuroplasticity science inform us about optimal therapeutic program designs? How do we apply that science, using modern technology, to drive neurological changes that address both the neurobehavioral distortions and the resulting behavioral deficits that are expressed in specific neurological and psychiatric disorders? By what strategies can we achieve the strongest and most complete rehabilitative corrections? These are questions that we have extensively explored in our efforts to establish new medical applications of neuroplasticity-based therapeutics. Here, we summarize the state of this rapidly emerging area of translational neuroscience, beginning with an explanation of the scientific premises and strategies, then describing their implementation in therapeutic software to address two human illnesses: the treatment of social cognition deficits in chronic schizophrenia and in autism; and the amelioration of age-related functional decline using strategies designed to delay the onset of--and potentially prevent--Alzheimer's Disease and related causes of dementia in aging.
