Neuronal Laterality in Parkinson's Disease With Unilateral Symptom by In Vivo 1H Magnetic Resonance Spectroscopy

On the basis of NAA/Cr ratios between the symptomatic and the asymptomatic sides, the present 1H MRS study shows a significant neuronal laterality in Parkinson's disease with unilateral symptoms. In vivo 1H MRS may provide a diagnostic marker for neuronal dysfunction in Parkinson's disease with unilateral symptoms.
