What is the purpose of this trial?

This trial explores whether a brain-training program called Lumosity can improve memory and thinking skills in individuals who have undergone a blood stem cell transplant. It also examines participants' interest in learning about their genetic risk for cognitive issues post-transplant. Two groups participate: one begins the Lumosity program immediately, while the other starts after three months. Eligible participants must have had a stem cell transplant at least three months prior, be in outpatient care, and have internet access. Participants should not have major neurological or psychiatric issues or have recently participated in a similar brain-training program. As an unphased trial, this study offers a unique opportunity to contribute to understanding cognitive recovery after stem cell transplants.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the Lumosity program is safe for improving neurocognitive function in HCT survivors?

Research has shown that Lumosity, a brain training program, is generally safe for use. In past studies, participants engaged in various games and exercises on Lumosity to train their brains. These studies have not identified any major negative side effects from using the program.

For instance, one study tested Lumosity and found it helped maintain thinking skills without harming participants. Another study suggested that playing brain games like those in Lumosity might help slow mental decline in some areas, again without causing major problems.

Overall, the evidence indicates that Lumosity is well-tolerated by users. Participants in these studies did not report any serious issues from using the program. This suggests that Lumosity is a safe choice for those looking to improve or maintain their mental abilities. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using Lumosity for post-transplant cognitive impairment because it offers a non-pharmacological approach to improving cognitive function. Unlike standard treatments that may focus on medication to manage symptoms, Lumosity is a brain-training program that uses engaging games and exercises to potentially enhance memory, attention, and problem-solving skills. This method is appealing because it is user-friendly, accessible from home, and can be tailored to individual cognitive needs, providing a personalized experience that traditional treatments may lack.

What evidence suggests that the Lumosity program is effective for improving neurocognitive function in HCT survivors?

Research shows that brain training programs like Lumosity can enhance brain function. Studies have found that these computer-based exercises can slow mental decline, keeping the brain sharp. In similar situations, such as surgery, brain training has reduced issues like confusion and memory loss shortly after the operation. In this trial, one group of participants will begin the Lumosity program at enrollment, while another group will start three months later. Although specific data for hematopoietic cell transplantation (HCT) survivors is limited, these findings suggest that Lumosity might also improve brain function in HCT survivors. ^{2 6 7 8 9}

In a study of 157 kidney transplant recipients, objective cognitive assessment using the Montreal Cognitive Assessment (MoCA) was found to be more reliable than clinical perceptions from physicians and nurses in identifying cognitive impairment.

The study revealed that clinical perceptions had low accuracy, with only 66% sensitivity for physicians and 65% for nurses in detecting cognitive impairment, highlighting the need for standardized cognitive screening tools in transplant patients.

Cognitive impairments are common in organ transplant candidates and recipients, with some patients, especially frail individuals, continuing to experience these issues even after transplantation, indicating a need for ongoing assessment.

New assessment tools for cognitive impairments, particularly in liver transplant candidates, show promise for integration into clinical practice, but further research is needed to establish effective assessment and intervention strategies post-transplant.

The culture-based virtual reality (VR) training program was found to be feasible and well-tolerated by patients with amnestic mild cognitive impairment (aMCI), with a high adherence rate of 91.55%.

Despite the program's feasibility, it did not lead to significant improvements in cognitive function as measured by various tests, including the Korean Mini-Mental State Examination and working memory assessments.

A meta-analysis of 43 studies involving 2,636 participants found that commercial brain training programs showed small but significant improvements in near-transfer effects for both healthy older adults and those with mild cognitive impairment (MCI).

However, there was no evidence of far-transfer benefits for MCI participants, and only limited improvements in processing speed for healthy adults, indicating that while brain training may be enjoyable, it lacks strong empirical support for enhancing memory or overall cognitive function.

An 8-week computer-based brain training program did not significantly improve cognitive functioning, quality of life, or self-efficacy in stroke patients compared to a control group, although there were minor improvements in working memory and speed.

The study highlights the limited effectiveness of such brain training interventions in enhancing cognitive abilities after stroke, suggesting that more research is needed to explore their potential benefits.

Computerized cognitive training (CCT) using LumosityTM showed feasibility for memory rehabilitation in stroke patients, with some participants reporting fewer memory failures during the intervention.

However, the study found no consistent evidence of effectiveness, as most participants did not show significant changes in subjective or objective memory measures, highlighting the variability in individual responses to the training.

Kidney transplant recipients (KTR) show significant long-term cognitive impairments, particularly in memory, mental speed, and executive functioning, compared to healthy controls, with 16% of KTR meeting criteria for mild cognitive impairment (MCI).

These cognitive impairments are not linked to age or disease-related factors but are associated with lower societal participation and quality of life, highlighting the need for neuropsychological assessments in KTR to address these issues.

In a study of 583 kidney transplant patients, 15.6% were found to have cognitive impairment, highlighting a significant issue in post-transplant care.

Cognitive impairment was linked to factors such as older age, male sex, lower education levels, hypertension, and obesity, suggesting that transplant centers should consider screening for cognitive issues, especially in high-risk patients.

A review of 18 commercially available brain training programs found that 7 of them were studied in 26 high-quality trials, with two programs showing strong Level I evidence for promoting cognitive health in older adults.

The overall methodological quality of the studies was high, suggesting that some computerized cognitive training programs can effectively support healthy brain aging, although caution is advised due to potential biases in reporting.
