尽管γ -氨基丁酸(GABA)神经元在精神分裂症死后出现了广泛的异常,但很少有研究测量体内组织中GABA的水平。我们使用质子磁共振波谱法测量了精神分裂症患者和健康对照者在前扣带皮层(ACC)和顶枕皮质(POC)中的组织GABA水平。21名接受稳定药物治疗的精神分裂症参与者(平均年龄39.0岁,男性14名)和19名健康对照者(平均年龄36.3岁,男性12名)在提供知情同意后,以4特斯拉的速度使用gaba选择性编辑进行质子磁共振波谱扫描。从两个16.7cc体素中收集数据,并使用LCModel进行分析。我们发现,与对照组相比,精神分裂症组两个脑区GABA/Cr均升高(F(1,65)=4.149, p=0.046) (ACC升高15.5%,POC升高11.9%)。我们还发现GABA/Cr和Glu/Cr之间存在正相关,这与GM百分比或脑区域无关。我们发现长期治疗的精神分裂症患者中GABA/Cr升高。死后研究报告了精神分裂症患者gaba能神经传递功能障碍的证据。慢性精神分裂症患者GABA水平的升高,无论是由疾病引起的还是代偿性的,都可能与GABA能神经传递功能障碍有关。
Despite widely-replicated abnormalities of gamma-aminobutyric acid (GABA) neurons in schizophrenia postmortem, few studies have measured tissue GABA levels in vivo. We used proton magnetic resonance spectroscopy to measure tissue GABA levels in participants with schizophrenia and healthy controls in the anterior cingulate cortex (ACC) and parieto-occipital cortex (POC). 21 schizophrenia participants effectively treated on a stable medication regimen (mean age 39.0, 14 male) and 19 healthy controls (mean age 36.3, 12 male) underwent a proton magnetic resonance spectroscopy scan using GABA-selective editing at 4 Tesla after providing informed consent. Data were collected from two 16.7cc voxels and analyzed using LCModel. We found elevations in GABA/Cr in the schizophrenia group compared with controls (F(1,65)=4.149, p=0.046) in both brain areas (15.5% elevation in ACC, 11.9% in POC). We also found a positive correlation between GABA/Cr and Glu/Cr which was not accounted for by %GM or brain region. We found elevated GABA/Cr in participants with chronically treated schizophrenia. Postmortem studies report evidence for dysfunctional GABAergic neurotransmission in schizophrenia. Elevated GABA levels, whether primary to illness or compensatory to another process, may be associated with dysfunctional GABAergic neurotransmission in chronic schizophrenia.
