Objectives: Although sleep paralysis (SP) has been known as one of the symptoms of narcolepsy, recently it has becoei recognized as occurring frequently in the general population. However, the prevalence of SP and its associated factors in patients with major psychiatric disorders remain unknown. This study investigated the prevalence of SP and a variety of associated xperiences in those patients.
Methods: The subjects were 160 psychiatric patients and 143 age- and sex-matched controls. The Korean version SPquestionnaire as well as the Sleep-Wake Schedule, Epworth Sleepiness Scale and Insomnia Severity Index were admiistered to all the subjects. The patients were referred from Dong-A University Hospital and consisted of 74 diagnosed as schizophrenia (47.7%), 26 as bipolar disorder (16.8%) and 55 as major depression (35.5%).
Results: Nearly 42% of the patient group and39% of the control group had experienced at least one episode of SP in their lifetime, with no significant difference between the groups. However, the patient group had experienced SP more frequently than the control group. Among all subjects, no gender dfference in SP incidence was found. The peak age of onset was in the range of 1625 years for both groups. Over eight tenths of both groups reported hallucinations and over seven tenths of both groups experienced fear accompanying SP.
Conclusion: This study shows that there is no difference in the lifetime prevalence of SP between psychiatric patients and th®eneral population, whereas frequency of SP experience is higher in psychiatric patients. Terrifying hallucinations and fearful feeling4requenty accompany SP in both groups. Sleep Medicine and Psychophysiology 2002:9(2) : 115-121
