Abstract:
Objective: To examine the relationship between the Apolipoprotein E (APOE) 4 allele and cognitive outcome in traumatic brain injured (TBI) patients. It was predicted that the carriers would exhibit significantly poorer cognitive outcomes.
Participants: Seventy-four TBI patients 16-59 years old were examined at discharge from inpatient rehabilitation programs. Thirty-nine patients were reassessed at one year follow-up.
Settings: Rehabilitation programs at Emory University School of Medicine and Shepherd Center in Atlanta, Georgia, and the Mayo Clinic College of Medicine in Rochester, Minnesota.
Methods: Neuropsychological assessments of attention, language, memory, visuoanalytic skills, and executive functioning were performed.
Results: The 4 positive and negative patients were comparable in demographics, length of rehabilitation stay, injury-test intervals, and severity of injury. Cognitive scores did not significantly differ between the groups at either test occasion.
Conclusions: These results do not suggest a significant relationship between APOE 4 and cognitive outcome from TBI.
