概括
患有双相情感障碍 (BD) 的患者表现出淋巴功能受损,通过沿周围血管空间 (DTI-ALPS) 的减少扩散张力图像分析和增加胆管体体积 (CPV) 表示. 这种功能障碍与BD患者的正面极缩有关.
科学领域:
- 神经科学是一个神经科学.
- 放射学 放射学是一门学科.
- 精神病学是一个精神病学.
背景情况:
- 双极性障碍 (BD) 患者面临更高的痴呆风险和大脑缩,可能是由于淋巴系统功能障碍和废物积累.
- 淋巴系统在清除废物中的作用对于预防细胞损伤和认知衰退至关重要.
研究的目的:
- 为了评估双相情感障碍患者的淋巴系统功能,使用DTI-ALPS和胆脉体积 (CPV).
- 调查淋巴清除指数与BD中的大脑缩之间的关联.
主要方法:
- 研究了两组双相情感障碍患者和健康对照 (HCs) (发现:28 BD,28 HCs;验证:42 BD,42 HCs).
- 测量了沿周脉空间 (DTI-ALPS) 的扩散张力图像分析,以及与总内体积 (CPV/TIV) 相对的胆脉体积.
- 进行了群体比较和相关性分析,以评估淋巴功能和前极缩.
主要成果:
- 与HC相比,BD患者的ALPS指数在两个队列中都显著下降.
- 发现队列显示在BD患者中增加了CPV/TIV和前极缩.
- 额头极缩与发现队列中ALPS指数下降相关,这表明ALPS介导的效应.
结论:
- 中年患有双相情感障碍的患者表现出淋巴管功能受损.
- 周血管空间的这种功能障碍可能会导致在BD中观察到的正面极缩.

Bipolar Disorder
60
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.

Mania and Antimanic Drugs: Overview
155
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...
