In this chapter, we review the research that has applied fractal measures to the study of the most common psychological disorders, that is, affective and anxiety disorders. Early studies focused on heart rate, but diverse measures have also been examined, from variations in subjective mood, or hand movements, to electroencephalogram or magnetoencephalogram data. In general, abnormal fractal dynamics in different physiological and behavioural outcomes have been observed in mental disorders. Despite the disparity of variables measured, fractal analysis has shown high sensitivity in discriminating patients from healthy controls. However, and because of this heterogeneity in measures, the results are not straightforward, and more studies are needed in this promising line.
在本章中，我们回顾了将分形测度应用于研究最常见的心理障碍，即情感和焦虑障碍的研究。早期的研究集中在心率上，但也检查了各种测量方法，包括主观情绪或手部运动的变化，以及脑电图或脑磁图数据。一般来说，在精神障碍中观察到不同生理和行为结果的异常分形动力学。尽管测量的变量存在差异，但分形分析在区分患者和健康对照方面显示出了很高的灵敏度。然而，由于这些测量方法的异质性，结果并不简单，在这一有前途的领域还需要更多的研究。
