Fearful thinking predicts hypervigilance towards pain-related stimuli in patients with chronic pain.

摘要: Cognitive impairment plays a role in the development and maintenance of chronic pain. Patients with painful disorders are reported to show attentional biases toward pain-related information. However, these findings controversial, rarely has any study examined whether pain patients have conditioned stimuli (CS). In this study, twenty-one diagnosed trigeminal neuralgia (TN) were recruited from neurosurgical department large urban general hospital. Sixteen family members pain-free volunteers included as two separate control groups. Pain ratings, anxiety, depression measured all subjects using questionnaires. Two dot probe tests performed, one that used pictures versus neutral faces cues, another presented three types CS cues predicted certain, uncertain, or no Our results demonstrate TN showed towards CSs signaled uncertain Moreover, ratings negative emotion about their conditions correlated significantly presence biases. The patients' close members, however, displayed uncertain-pain CS. This demonstrates increased attention information, fearful thinking was positively phenomenon.
