概括
肥胖和双相情感障碍 (BD) 与大脑中的白质异常有关. 超重/肥胖会加剧这些大脑变化,并可能影响BD患者的药物效应.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 肥胖问题研究研究
背景情况:
- 肥胖在双相情感障碍 (BD) 中很常见,但其对双相情感障碍白质完整性的影响尚不清楚.
- 之前的研究集中在灰质上,使白质变化与同时发生的肥胖和BD相关的变化未得到充分探索.
研究的目的:
- 调查身体质量指数 (BMI),双相情感障碍诊断和白质部分异性质 (FA) 之间的关联.
- 探索BMI和BD诊断如何与药物对白质完整性的影响相互作用.
主要方法:
- 利用扩散张力成像 (DTI) 从899名患有BD和1287名对照组的20个队伍 (ENIGMA-BD) 获得了微分异构 (FA) 数据.
- 在22个白质道中进行了一项大型分析,检查了BMI,BD诊断,药物 (包括) 和FA之间的关系.
主要成果:
- 较低的FA与六个白质通道的BD和较高的BMI有关,包括体和胸膜辐射.
- 超重/肥胖和BD在一些重叠的白质区域中独立显示较低的FA.
- 治疗削弱了BMI和FA之间的关联,而更大的体重放大了与药物相关的FA减少.
结论:
- 肥胖可能导致双相情感障碍中大脑白质变化.
- 肥胖对BD白质完整性的影响很大,可能会调节精神病药物的效果.

Bipolar Disorder
56
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Bulimia Nervosa
52
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...

Attention-Deficit/Hyperactivity Disorder
45
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Obesity
383
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Depression: Overview
221
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
