- 医疗成像医学成像
- 图形理论 图形理论
背景情况:
- 神经性厌食症 (AN) 与显著的神经变化有关.
- 了解AN中的大脑网络组织对于治疗至关重要.
- 图形理论为分析复杂的大脑结构提供了新的工具.
研究的目的:
- 为了研究皮质厚度 (CT) 和化模式在青少年与AN.
- 评估在短期恢复体重之前和之后这些模式的变化.
- 探索大脑网络组织与AN中的临床因素之间的关系.
主要方法:
- 结构磁共振成像 (sMRI) 用于38名患有AN的女性青少年和53名健康对照 (HCs).
- 应用图形理论指标来分析CT和旋转网络.
- 在重量恢复后对AN组进行了纵向分析,并对临床关联进行了回归分析.
主要成果:
- 与HC相比,急性AN患者在CT图中显示了降低的模块化和小世界指数 (SWI).

Anorexia Nervosa
102
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa
116
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Binge Eating Disorders
101
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Longitudinal Studies
171
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Depressive Disorders: Etiology
104
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
