最近的症状激发研究将患有牙科恐惧症的患者与健康对照者进行了比较,发现了基底神经节结构的过度激活,但没有一个研究评估纹状体功能连接。我们重新分析了先前关于牙科恐惧症的功能性磁共振成像研究的数据。患者(20名男性,25名女性)和健康对照组(18名男性,23名女性)观看了显示牙科治疗和中性内容的图片。我们通过心理生理相互作用(PPIs)进行了连通性分析。与非恐惧控制组相比,患者前额叶和基底神经节区域之间的连通性下降。此外,临床组的特点是内基底节区连通性增加,这在女性患者中比男性患者更明显。该研究首次证明,在视觉症状激发期间,牙齿恐惧症患者的额纹状体网络内的信息流发生了改变,这可以被认为是该疾病的神经标志物。
Recent symptom provocation studies that compared patients suffering from dental phobia with healthy controls identified hyperactivation of basal ganglia structures, but none have assessed striatal functional connectivity. We reanalyzed data from a previous functional magnetic resonance imaging study on dental phobia. Patients (20 men, 25 women) and healthy controls (18 men, 23 women) had been exposed to pictures showing dental treatment, and neutral contents. We conducted connectivity analyses via psychophysiological interactions (PPIs). Relative to non-phobic controls, the patients showed decreased connectivity between prefrontal and basal ganglia regions. Moreover, the clinical group was characterized by increased internal basal ganglia connectivity, which was more pronounced in female compared with male patients. This study provides first evidence for an altered information flow within a fronto-striatal network in dentophobic individuals during visual symptom provocation, which can be considered a neuromarker of this disorder.
