To search for discriminating biomarkers, 30 patients with idiopathic rapid-eye-movements sleep behavior disorder (iRBD) were compared with 17 patients with RBD within narcolepsy type 1. Both groups underwent extensive examinations, including skin biopsy searching for phosphorylated α-synuclein deposits and whole-night video-polysomnography. Skin biopsy was positive for phosphorylated α-synuclein deposits in 86.7% of iRBD patients and in none of narcoleptic patients. The analysis of video-polysomnographic motor events showed differences in their occurrence throughout the night in the two groups. iRBD and RBD due to narcolepsy do have different clinical and pathological findings, confirming a different pathophysiology.
为了寻找有区别的生物标志物,将 30 名特发性快速眼动睡眠行为障碍(iRBD)患者与 17 名 1 型发作性睡病相关的 RBD 患者进行比较。两组均接受了广泛的检查,包括皮肤活检以寻找磷酸化 α-突触核蛋白沉积物和整夜视频多导睡眠图。皮肤活检显示,86.7%的 iRBD 患者和无 1 型发作性睡病患者的磷酸化 α-突触核蛋白沉积物呈阳性。对视频多导睡眠图运动事件的分析显示,两组患者夜间的发生情况存在差异。iRBD 和由发作性睡病引起的 RBD 确实有不同的临床和病理发现,这证实了不同的病理生理学机制。
