| Popis: | The burden of rapid eye movement (REM) sleep behaviour disorder is well documented, however the significance of isolated REM sleep without atonia is unclear. We evaluated the prevalence and predictors of RSWA in a sleep clinic population. We analysed data in three groups—patients meeting American Academy of Sleep Medicine (AASM) criteria for loss of REM atonia (RSWA), elevated REM EMG activity which did not meet AASM criteria (Elevated REM EMG) and those with no elevated REM EMG activity (normal). Analysis included 511 diagnostic sleep studies over 6 months. RSWA was identified in 36 (5.8%) and elevated REM EMG activity in 44 (8.6%) patients. The RSWA group, compared with the normal group, had a higher use of medications (anti-depressants, beta blockers and anti-cholinesterase inhibitor) OR 2.05 (95% CI 1.0–4.1), p = 0.04. Periodic limb movement indices in REM were different between groups: RSWA mean (95% CI) = 22.5/h, (11.0–33.9), elevated REM EMG = 8.6/h, (5.1–12.2), normal mean = 0.9/h (0.6–1.3), p |
