Abstract：Objective To study the somnipathy in patients with multiple system atrophy(MSA)using polysomnography(PSG).Methods Six MSA patients and 6 healthy controls underwent PSG.Total sleep time,sleep efficiency,sleep latency,wake after sleep onset(WASO),awaking times,sleep stages,microarousal index,apnea-hypopnea index(AHI),and periodic limb movement of sleep index(PLMSI)were compared between two groups.Results Compared with control group,total sleep time and sleep efficiency were lower(P＜0.0l),while WASO,N1 light sleep,microarousal index,AHI,and PLMSI were higher in control group(P＜0.01 or 0.05).In addition,REM sleep dystonia,stridor and disturbed episodes occurred in 5,4 and 2 MSA patients.Conclusion There is a severe somnipathy in MSA patients.
