title: 1H-magnetic resonance spectroscopy in obsessive-compulsive disorder: evidence for neuronal loss in the cingulate gyrus and the right striatum.
abstract: We compared 12 patients with obsessive-compulsive disorder (OCD) and six control subjects by 1H-magnetic resonance spectroscopy. Significantly lower relative N-acetyl-aspartate (NAA) levels were found in the right striatum of OCD patients, as well as a decrease of anterior cingulate NAA that correlated with severity of illness. Age and sex were correlated to striatal NAA levels.
