title: Proton magnetic resonance spectroscopy of basal ganglia in chronic schizophrenia.
abstract: Proton spectra in the regions of the right and left basal ganglia were studied in 14 medicated patients with chronic schizophrenia using proton magnetic resonance spectroscopy (1H MRS). Ratios of N-acetyl-aspartate (NAA) to choline-containing compounds (Cho) were significantly reduced in the bilateral basal ganglia regions compared to normal subjects. The relative level of Cho was increased in the left basal ganglia region in comparison to normal subjects. This finding suggests the presence of disturbances in phospholipid metabolism in the basal ganglia. The level of NAA was decreased in the bilateral basal ganglia regions, which may indicate neuronal dysfunction. The 1H MRS study demonstrated dysfunctions in the basal ganglia regions in medicated patients with chronic schizophrenia.
