３２例无先兆偏头痛患者于发作间歇期，进行了四种、理量表和听觉Ｐ_（３００）检查，以３２例健康人作对照。显示偏头痛患者的艾森克个性问卷（ＥＰＯ）的神经质记分（Ｎ），Ａ型行为量表的ＴＨ和ＣＨ分，以及焦虑和抑郁自评量表（ＳＡＳ、ＳＤＳ）的得分均显著高于对照组；Ｐ_（３００）中的Ｎ_２波及Ｐ_３波的波幅低于对照组（Ｐ＜０．０５），各波的潜伏期及其余各波波幅均正常。经治疗症状好转后复查仅ＴＨ分数较前明显降低（Ｐ＜０．０５），原因有待探讨。所得结果支持偏头痛具有明显性格特征及情感障碍之说，且有轻度认知功能障碍。因前二者之间关系密切，而认知障碍与性格和情感改变无平行关系，故考虑情感改变可能也是偏头痛发作的因素之一，或与偏头痛有相同的发病因素。而认知障碍则可能为头痛的结果。研究表明应重视偏头痛防治中的心理因素。
Thirty-two patients without aura migraine during the interictal episode were examined with four scales, psychometric scales and auditory P300 examinations, and 32 healthy controls were used as controls. Scores of neuroticism (N), TH and CH scores of type A behavior scale, and anxiety and depression self-rating scale (SAS, SDS) were significantly higher in migraine patients with EQI The amplitude of N_2 and P_3 in P_ (300) was lower than that in the control group (P <0.05). The latency of each wave and the amplitude of other wave were normal. After the treatment of symptoms improved review only TH fraction was significantly lower (P <0.05), the reasons to be explored. The results support the hypothesis that migraine has significant personality traits and affective disorders, with mild cognitive impairment. Due to the close relationship between the two, and cognitive impairment and personality and emotional change is not paralleled, so consider the emotional changes may also be one of the factors of migraine attacks, migraine or have the same risk factors. Cognitive disorders may be the result of headaches. Studies have shown that attention should be paid to the psychological factors in the prevention and treatment of migraine.
