Summary
Neurobehavioral functioning, including executive function, memory, and persistent depression, impacts long-term survival in lung transplant recipients. Poor neurocognitive performance and elevated depressive symptoms are linked to increased mortality post-transplant.
Area of Science:
- Transplant Surgery
- Psychology
- Pulmonology
Background:
- Neurobehavioral functioning is crucial for lung transplant candidates, yet its link to clinical outcomes remains unclear.
- This study investigates the relationship between pre-transplant neurobehavioral factors and long-term survival in lung transplant recipients.
Purpose of the Study:
- To examine the association of executive function, memory, depression, and anxiety with long-term survival after lung transplantation.
- To identify neurobehavioral predictors of mortality in lung transplant recipients.
Main Methods:
- A cohort of 201 lung transplant recipients from a dual-site clinical trial were assessed.
- Baseline neurocognitive testing (executive function, memory), depression (Beck Depression Inventory-II), and anxiety (Spielberger State-Trait Anxiety Inventory) were evaluated.
- Patients were followed for up to 12 years for survival outcomes.
Main Results:
- Lower executive function and memory performance were independently associated with increased mortality.
- Persistently elevated depressive symptoms (BDI-II score >13 at baseline and 3 months) predicted greater mortality (HR=1.85).
- Pre-transplant depression and anxiety alone were not significant predictors of mortality.
Conclusions:
- Neurobehavioral functioning, specifically impaired executive function, memory, and persistent depressive symptoms, is associated with reduced long-term survival after lung transplantation.
- These findings highlight the importance of assessing neurobehavioral health in lung transplant candidates to optimize patient outcomes.
