How common is cognitive dysfunction in children who have had a liver transplant?
Cognitive dysfunction refers to problems with thinking, memory, attention, or learning. For children who have had a liver transplant, this is a known concern. A large 2024 meta-analysis of 38 studies including 7,494 children found that about 1 in 4 (24%) experience some form of cognitive dysfunction after transplant 15. The risk is higher for children who receive a transplant before their first birthday (39.4%) and varies by region, with the highest rate in Asia (30.6%) 15.
What the research says
A 2024 systematic review and meta-analysis pooled data from 38 studies and found the overall incidence of cognitive dysfunction after pediatric liver transplant is 24% (95% confidence interval: 19% to 30%) 15. This means that for every 100 children who receive a liver transplant, about 24 will have some cognitive difficulty. The study identified several factors that increase risk: disease-related factors (like the original liver condition), treatment-related factors (such as medications or hospital stays), individual factors (like age at transplant), cognitive-behavioral factors, and social factors 15. Children transplanted before age 1 had the highest rate at 39.4%, and the rate in Asia was 30.6% 15. The authors concluded that a multifactorial approach is needed to assess and improve long-term cognitive outcomes 15. Other sources on cognitive dysfunction in different populations (e.g., COVID-19 survivors, older adults with neurodegenerative disease, or maple syrup urine disease) are not directly relevant to pediatric liver transplant 2346.
What to ask your doctor
- What is my child's individual risk for cognitive problems after transplant, based on their age and medical history?
- Are there specific cognitive assessments or developmental screenings recommended after transplant?
- What signs of cognitive dysfunction should I watch for at home (e.g., trouble with schoolwork, memory, attention)?
- Are there any interventions or therapies (like cognitive rehab or school support) that could help if problems arise?
- How often should my child have follow-up evaluations for cognitive development?
