MR spectroscopy in 3 patients with AESD revealed decreased N -acetylaspartate (NAA) and elevated glutamine/glutamate complex (Glx) during the week of presentation. Afterward, Glx normalized, whereas NAA remained low in 2 patients with neurologic sequelae but nearly normalized in the third patient without neurologic sequelae. These findings support the hypothesis that excitotoxic neuronal damage plays an important role in the pathogenesis of AESD and suggest that MR spectroscopy might be predictive of outcome.
