背景情况:
- 双极性障碍 (BD) 是一种复杂的心理健康状况.
- 了解潜在的大脑结构异常对于诊断和治疗至关重要.
- 传统的方法,如基于声素的形态测量 (VBM),在检测微妙的变化方面存在局限性.
研究的目的:
- 通过基于变形的形态测量 (DBM) 来研究双相情感障碍 (BD) 患者的大脑结构变化.
- 将DBM与传统的基于声素的形态学 (VBM) 进行比较,以识别 BD 中的灰质 (GM) 和白质 (WM) 异常.
- 探索融合DBM和VBM数据以改善BD诊断的潜力.
主要方法:

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Bipolar Disorder
628
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.
