摘要

目的严重疲劳是多发性硬化症(MS)的一种普遍致残症状。本研究测试了严重疲劳的多发性硬化症患者是否存在与疲劳和体力活动相关的注意偏差(AB)和躯体解释偏差(IB)。方法严重疲劳的多发性硬化症或慢性疲劳综合症(ME/CFS)患者和健康对照组完成一项视觉探测任务(VPT),评估与疲劳和体力活动相关的注意偏差;并完成一项躯体解释偏差(IB)任务,评估以躯体威胁或更中性的方式解释模糊信息的倾向。38名多发性硬化症患者、44名ME/CFS患者和46名健康对照者完成了VPT任务;156名、40名和46名参与者分别完成了IB任务。结果表明,在与疲劳相关的AB或与体力活动相关的AB方面,组间差异无统计学意义(主题×条件间交互作用的总括检验:F2,125 = 1.87):F2,125 = 1.87; p = .159)。与健康对照组相比,两组患者都表现出以躯体威胁的方式解释模糊信息的倾向(F1,2 = 27.61, p <.001)。与 ME/CFS 患者相比,多发性硬化症患者的这种 IB 明显更强。IB与多发性硬化症患者对症状的认知反应明显相关。这可能助长了处理症状的无益方式,并可能导致多发性硬化症严重疲劳的持续存在。

The presence of attentional and interpretation biases in patients with severe MS-related fatigue

Objective

Severe fatigue is a prevalent and disabling symptom in multiple sclerosis (MS). This study tested if a fatigue- and physical activity-related attentional bias (AB) and a somatic interpretation bias (IB) are present in severely fatigued patients with MS. Biases were compared to healthy controls and patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Method

Severely fatigued patients with MS or ME/CFS and healthy controls completed a Visual Probe Task (VPT) assessing fatigue- and physical activity-related AB and an IB task that assesses the tendency to interpret ambiguous information in either a somatically threatening way or in a more neutral manner. The VPT was completed by 38 MS patients, 44 ME/CFS patients, and 46 healthy controls; the IB task was completed by 156, 40 and 46 participants respectively.

Results

ANOVA showed no statistically significant group differences in a fatigue-related AB or physical activity-related AB (omnibus test of interaction between topic × condition: F2,125 = 1.87; p = .159). Both patient groups showed a tendency to interpret ambiguous information in a somatically threatening way compared to healthy controls (F1,2 = 27.61, p < .001). This IB was significantly stronger in MS patients compared to ME/CFS patients. IB was significantly correlated with cognitive responses to symptoms in MS patients.

Conclusion

MS patients tend to interpret ambiguous information in a somatically threatening way. This may feed into unhelpful ways of dealing with symptoms, possibly contributing to the perpetuation of severe fatigue in MS.
