title: Longitudinal decline of the neuronal marker N-acetyl aspartate in Alzheimer's disease.
abstract: In patients with Alzheimer's disease, but not in health controls, longitudinal magnetic resonance spectroscopy shows a striking decline in the neuronal marker, N-acetyl aspartate, despite little decline in underlying grey-matter volume.
