精神心理性疾病的发病机理,长期停留在对精神心理过程的分析、假设和推测上,而对其发病的物质基础则了解甚少,也重视不够。对该类疾病的诊断,主要依靠病史和病人主诉的主观症状,缺乏客观的诊断检查手段。近年来,GABA/BZ(γ氨基丁酸/苯二氮草)受体研究的进步,和放射性核素受体显像的出现,可能为精神心理性疾病提供以物质手段为基础的客观检查,从而使精神心理性疾病的诊断,不只是从精神心理的角度,同时也从生化生理的角度进行。以脑功能性改变为主要特征的精神心理性疾病,由于缺乏解剖结构的异常,不能依靠现行的X线CT等进行诊断。脑受体显像,是近年来发展起
The pathogenesis of mental-psychological diseases, long-term stay in the analysis of mental processes, assumptions and speculation, while the incidence of their material basis is little understood, but also not enough attention. The diagnosis of such diseases, mainly rely on the history and patient complaints of the subjective symptoms, the lack of objective diagnostic tests. In recent years, advances in GABA / BZ (gamma aminobutyric acid / benzodiazepine) receptor research and the advent of radionuclide receptor imaging may provide objective, material-based examination of psychiatric disorders, So that the diagnosis of mental and psychological diseases, not only from the psychological point of view, but also from the biochemical and physiological point of view. Psychiatric disorders characterized by changes in brain function can not be diagnosed by current X-ray computed tomography (CT) due to lack of anatomic abnormalities. Brain receptor imaging has developed in recent years
