[3] NAA gives off the largest signal in magnetic resonance spectroscopy of the human brain.
The levels measured there are decreased in numerous neuropathological conditions ranging from brain injury to stroke to Alzheimer's disease.
This fact makes NAA a potential diagnostic molecule for doctors treating patients with brain damage or disease.
[7] High NAA levels in the hippocampus are related to better working memory performance in humans.
[8] Whole-brain levels of NAA have also been found to be positively correlated with educational attainment in adults.
