研究目的: |
1. 通过多模态脑 MRI 技术,探究肥胖儿童相较于正常体重儿童在脑结构(如灰质体积、白质微结构)、功能(如局部一致性、低频振幅)及类淋巴系统(如血管周围间隙形态、类淋巴指数)的特异性改变; 2.明确这些改变与肥胖相关指标及认知功能损伤的关联; 3.通过纵向随访研究,观察这些改变随时间的动态变化,及其与肥胖相关指标、认知功能损伤的关联。 |

|
Objectives of Study: |
1. To investigate the specific alterations in brain structure (e.g., gray matter volume, white matter microstructure), brain function (e.g., regional homogeneity, amplitude of low-frequency fluctuation) and the glymphatic system (e.g., perivascular space morphology, glymphatic index) in obese children compared with normal-weight children by using multimodal brain magnetic resonance imaging (MRI) techniques. 2. To clarify the correlations between the above-mentioned brain index alterations and obesity-related indicators, as well as cognitive function impairments in children. 3. To observe the dynamic changes of brain structure, function and glymphatic system indicators over time through longitudinal follow-up, and explore their correlations with obesity-related indicators and cognitive function impairments. |
