To investigate the metabolite changes in subjects with AD, MCI, and cognitively normal (CN) elderly during a memory task using dynamic MRS at a 3T MRI system, we included 95 subjects who included: 23 young normal control (YC), 24 cognitively normal (CN) elderly, 24 aMCI, and 24 mild and probable AD. The functional MRS data were measured during the face-name association task with the stimulation paradigm of fixation, novel, and repeat conditions. The fMRS data were analyzed using the LCModel software. Glx was altered during the stimulation conditions, which can be used in neuronal dysfunction for a patient with dementia.
