Correlation of Insulin-Like Growth Factor 1 With Cognitive Functions in Mild Traumatic Brain Injury Patients.
Ou et al., Neurotrauma Rep 2023
DOI: 10.1089/neur.2023.0085
Key Findings:
- Novelty: This study investigates Insulin-like growth factor 1 (IGF-1) as a potential prognostic marker for cognitive outcomes in patients with mild traumatic brain injury (mTBI).
- Importance: Identifying reliable prognostic markers is crucial for predicting recovery trajectories in mTBI patients, which can vary widely.
- Contribution: The research adds to the limited body of literature on the role of IGF-1 in mTBI recovery, particularly in relation to cognitive functions.
Results:
- The study included 295 mTBI patients and 200 healthy controls, focusing on demographic characteristics, injury causes, and IGF-1 levels.
- Cognitive functions were assessed using the Wisconsin Card Sorting Test (WCST).
- mTBI patients showed worse cognitive outcomes on the WCST, except for the “Learning to Learn” index.
- Significant correlations were found between IGF-1 levels, demographic factors, and specific WCST scores.
- Regression models indicated that IGF-1, along with age and education years, significantly influenced various WCST scores, highlighting their potential as prognostic markers.
Conclusion:
The study suggests that IGF-1 levels, in conjunction with demographic factors, may serve as important indicators for cognitive recovery in mTBI patients, particularly in tasks that require cognitive flexibility and problem-solving.
