Abstract

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.
