项目摘要

DESCRIPTION (provided by applicant): This K-23 Mentored Patient-Oriented Career Development Award application requests support to provide training for the applicant to become a neuroimaging researcher in human cognitive neuroscience specializing in understanding the illness, anorexia nervosa and to perform a research project that will investigate the linkages between neural correlates of social thinking and the pathology of anorexia nervosa. During residency, the applicant's research background as a cortical neurophysiologist led her to begin a pilot project utilizing functional neuroimaging tasks in eating disorders. This project identified three cortical regions with different activation in thinking about one's own self-identity and understanding relationships between others in patients in the process of recovering from anorexia nervosa. The proposed project will now examine the activation of these regions: the cingulate, the precuneus, and the temporoparietal junction in three different subject groups: healthy controls, currently ill anorexia nervosa patients, and fully recovered anorexia nervosa patients. These comparisons will improve our understanding of cortical changes associated with illness and recovery in anorexia nervosa. In addition to the neuroimaging data, each participant will complete assessments providing psychiatric and medical history, psychological scales related to the fMRI tasks, and neurocognitive measures. Activation of these neural regions by the fMRI tasks will also be correlated with the assessments to distinguish between cortical differences that relate specifically to the presence of the illness and differences that relate to other psychological measures and may reflect a trait of patients that have anorexia nervosa. These studies will allow the applicant to meet her immediate career goal: development as an independent translational neuroimaging researcher in anorexia nervosa. With this study and training, the applicant will be prepared to meet her long-term career goal of becoming an independent investigator examining the relationship between biological mechanisms and psychological function in both the development and resolution of anorexia nervosa. PUBLIC HEALTH RELEVANCE: Anorexia nervosa is a serious psychiatric illness afflicting approximately 1% of adolescent and young adult women for which both causes and treatments are not understood. This research project examines how neural activation of cortical areas related to social thinking and identity differ between individuals with anorexia nervosa and individuals who have recovered from anorexia nervosa. This study will also improve our understanding of the relationship between psychological and biological factors in anorexia nervosa.

描述（由申请人提供）：此 K-23 以患者为导向的指导职业发展奖申请要求支持为申请人提供培训，使其成为人类认知神经科学领域的神经影像研究员，专门了解神经性厌食症疾病并开展研究项目这将研究社会思维的神经相关因素与神经性厌食症病理学之间的联系。在住院医师实习期间，申请人作为皮质神经生理学家的研究背景促使她开始了一个利用功能性神经影像任务治疗饮食失调的试点项目。该项目确定了神经性厌食症患者在思考自我认同和理解他人关系时具有不同激活程度的三个皮质区域。拟议的项目现在将检查三个不同受试者组中这些区域的激活：扣带回、楔前叶和颞顶交界处：健康对照组、目前患病的神经性厌食症患者和完全康复的神经性厌食症患者。这些比较将提高我们对与神经性厌食症疾病和恢复相关的皮质变化的理解。除了神经影像数据外，每位参与者还将完成评估，提供精神病史和病史、与功能磁共振成像任务相关的心理量表以及神经认知测量。功能磁共振成像任务对这些神经区域的激活也将与评估相关，以区分与疾病存在具体相关的皮质差异和与其他心理测量相关的差异，并可能反映神经性厌食症患者的特征。这些研究将使申请人能够实现她近期的职业目标：发展成为神经性厌食症的独立转化神经影像研究员。通过这项研究和培训，申请人将准备好实现她的长期职业目标，即成为一名独立研究者，研究神经性厌食症的发展和解决中的生物机制和心理功能之间的关系。公共卫生相关性：神经性厌食症是一种严重的精神疾病，大约有 1% 的青少年和年轻成年女性患有这种疾病，其原因和治疗方法尚不清楚。该研究项目研究了神经性厌食症患者和神经性厌食症康复者之间与社会思维和身份相关的皮质区域的神经激活有何不同。这项研究还将提高我们对神经性厌食症心理和生物因素之间关系的理解。
