What this trial studies

This pilot study evaluates the feasibility and preliminary efficacy of EndeavorRx, an FDA-approved electronic attentional-control training program, for children aged 8-16 with sickle cell disease (SCD). Participants will engage with the program for 25-30 minutes daily, five days a week, over four weeks, in a game-like environment that adapts to their performance. The study aims to assess improvements in attention and cognitive functioning, which are often impaired in children with SCD due to cerebral infarcts. The intervention is designed to help mitigate the cognitive deficits associated with SCD and improve overall quality of life.

Who should consider this trial

Good fit: Ideal candidates are children aged 8-16 diagnosed with sickle cell disease who have been on monthly blood transfusions for at least three months and exhibit significant attention deficits.

Not a fit: Patients with an estimated IQ below 70, significant motor or sensory impairments, or pre-existing mental health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could enhance cognitive functioning and attention in children with sickle cell disease, leading to better academic and life outcomes.

How similar studies have performed: Previous studies have shown positive effects of EndeavorRx in youth with ADHD, suggesting potential for success in similar cognitive deficits in SCD.
