Few comparative studies exist of metabolic brain changes among neurodegenerative illnesses. We compared brain metabolic abnormalities in Alzheimer’s disease (AD) and in Parkinson’s disease with dementia (PDD) as measured by proton magnetic resonance spectroscopy (MRS). Twelve patients with idiopathic PDD, 22 patients with probable mild AD, and 61 healthy older controls underwent posterior cingulate MRS. Patients with AD showed reduced N-acetylaspartate (NAA)/creatine (Cr) (p <0.05) and increased choline (Cho)/Cr (p <0.05) and myo-Inositol (mI)/Cr (p <0.01) compared to controls. Patients with PDD showed reduced NAA/Cr (p <0.05) and glutamate (Glu)/Cr (p <0.01) compared to controls. There was reduced Glu/Cr in PDD compared to AD (p <0.01). Patients with AD and patients with PDD showed distinct brain metabolic MRS profiles. Findings suggest that comparison of brain MRS profiles across dementias provides useful direction for future study.
