PET STUDIES IN ATTENTION DEFICIT DISORDER: ROLE OF DOPAMINE

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。这项研究的目的是观察注意力缺陷多动障碍患者大脑中的一种化学物质多巴胺是否存在异常。多巴胺与运动、思考或集中注意力的能力以及快乐有关。将小剂量的哌甲酯（一种释放多巴胺的药物）和放射性示踪剂（一种放射性化学物质，可以指示当您接受哌甲酯时大脑释放了多少多巴胺）注射到静脉中，然后正电子发射断层扫描（PET）相机拍摄体内放射性示踪剂的运动。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of the study is to see if there are abnormalities in dopamine, a chemical found in the brain, in people with Attention Deficit Hyperactive Disorder. Dopamine is linked with movement, ability to think or concentrate, and pleasure. A small dose of methylphenidate (a drug which releases dopamine) and a radiotracer, which is a radioactive chemical that indicates how much dopamine is released by your brain when you receive the methylphenidate, are injected into a vein and then a Positron Emission Tomography (PET) camera takes pictures of the movement of the radiotracer in the body.
