Abstract:
:In addition to the study of pathological conditions, magnetic resonance spectroscopy can provide useful information about brain-behavior relationships in normal subjects. Recently, there have been reports of correlations between N-acetylaspartate (NAA) values and cognitive functions in normal adults. We tested the possible specific relationship between the NAA/choline (Cho) ratio in the medial temporal lobe and memory performance in normal adolescents. The medial temporal NAA/Cho ratio was unrelated to age, gender and general intelligence but presented a clear correlation with several memory measures. In the regression analysis two memory variables (RAVLT learning and a face-name recognition task) explained 55.6% of NAA/Cho variance. We conclude that NAA values in the medial temporal lobe are related to memory abilities but not to global intelligence in normal adolescent subjects.
