Differential diagnosis of bipolar II disorder (BD-II) and borderline personality disorder (BPD) has always been challenging for clinicians due to symptoms' overlap. This study aimed to compare hot and cold executive functions (EFs) in BD-II patients, as well as BPD and healthy controls (HCs), in order to differentiate these two disorders.
In the present study, 30 BD-II and 30 BPD patients undergoing the drug therapy with mood stabilizers, and 30 HC were examined using EFs evaluated tests. The data were then analyzed using ANOVA and Tukey post hoc test.
The BD-II Patients performed significantly less in all cold EFs than the HC. Also, BPD patients had meaningfully lesser performance compared to HC in all cold EFs except sustained attention. No significant difference was perceived between the two patient groups in the cold EFs. In BD-II patients, the risky decision-making as a hot EFs' component was not significantly different from HC; nevertheless, its amount was significantly higher in BPD than in the HC and BD-II patients.
These findings underline the differences between the two mentioned disorders based on the hot EFs, which may indicate further disorder in the emotional information processing system among the BPD patients.
由于症状重叠，双相II型障碍（BD-II）和边缘型人格障碍（BPD）的鉴别诊断一直是临床医生面临的挑战。本研究旨在比较BD-II患者以及BPD患者和健康对照（HC）的冷热执行功能（EFs），以区分这两种障碍。
在本研究中，对30例正在接受情绪稳定剂药物治疗的BD-II患者、30例BPD患者和30例HC使用执行功能评估测试进行检查。然后使用方差分析和Tukey事后检验对数据进行分析。
BD-II患者在所有冷执行功能方面的表现均显著低于HC。此外，除持续注意力外，BPD患者在所有冷执行功能方面的表现均显著低于HC。在冷执行功能方面，两组患者之间未观察到显著差异。在BD-II患者中，作为热执行功能组成部分的风险决策与HC无显著差异；然而，其在BPD患者中的程度显著高于HC和BD-II患者。
这些发现强调了基于热执行功能的上述两种障碍之间的差异，这可能表明BPD患者的情绪信息处理系统存在进一步紊乱。
