This randomized controlled clinical trial evaluates neurocognitive, biopsychological, and brain connectome outcomes in children and adolescents with acute lymphoblastic leukemia who have previously received Chimeric Antigen Receptor T-cell therapy (CAR T-cell therapy), chemotherapy, and/or hematopoietic stem cell transplantation (HSCT).
Participants will receive a multimodal, telematic psychological intervention combining digital cognitive training and an adapted mindfulness-based emotional regulation program. Outcomes will be compared with a waitlist control group and intervention sequences will be counterbalanced: (1) cognitive training followed by mindfulness; and (2) mindfulness followed by cognitive training.
Neurocognitive performance, emotional-behavioral functioning, executive functioning and EEG-based functional connectivity will be assessed at baseline, post-intervention and at 6 months follow-up.
