In Denmark, around 25 children undergo allogeneic HSCT every year, of these approximately 85-90% survive into adulthood.\n\nThe goal of this observational study is to learn about neurocognitive outcomes in children undergoing (HSCT) and to understand which clinical, physical, and environmental factors may affect neurocognitive development during the first year after transplant. The main questions it aims to answer are:\n\nHow does neurocognitive function change from before HSCT to one year after transplantation in pediatric patients?\n\nWhich clinical, physical, and environmental factors are linked to better or worse neurocognitive outcomes?\n\nParticipants will:\n\nComplete neurocognitive tests before HSCT and at 1-year follow-up, covering intelligence, memory, attention, executive function, processing speed, and motor skills.\n\nUndergo physical tests before HSCT, at hospital discharge, at 6-months follow-up, and at 1-year follow-up, including muscle strength, mobility, endurance, balance, and cardiopulmonary fitness (only at 1-year follow-up).\n\nWear activity trackers to measure physical activity and sedentary time during hospitalization at 6 months and 1-year post-HSCT.\n\nComplete questionnaires about sleep, pain, quality of life, fatigue, family background, and exposure to outdoor and green spaces.\n\nHave medical records reviewed for treatment-related side effects, immune recovery, inflammation, and pain management.\n\nThis study will help understand how neurocognitive function develops after HSCT in children and which factors (clinical, physical, or environmental) may support better recovery and well-being.",[69,70,71,72,73,74,75,76],"HSCT","Pediatric Cancer","Pediatric Patients","Late Effect","Toxicity","Neurocognitive Dysfunction","Physical Function","Physical Capacity","NOT_YET_RECRUITING","2026-02-18",{"date":80,"type":81},"2026-02-20","ACTUAL",{"date":83,"type":65},"2026-02-15",{"date":85,"type":65},"2031-12-31",{"name":5,"class":6},1]
