Prevalence of Sleepwalking in an Adult Population

ABSTRACT

Background: Sleepwalking consists of a series of behavioral activities that occur during sleep. These activities may be simple; complex or aggressive in nature. They include motor activities; confusion; and amnesia for the events. Sleepwalking is a disorder of arousal from non-rapid eye movement (NREM) sleep. In children; episodes of sleepwalking are rarely violent; in adults; however; sleepwalking might include violence; which could endanger the patient or others and might precipitate legal issues. There is inadequate information on the prevalence and demographic correlates of sleepwalking in Nigeria. Objectives: One objective of this study was to determine the lifetime prevalence rate of sleepwalking in an adult population in Ile-Ife; in Southwestern Nigeria. Another objective was to determine the age and sex distribution of sleepwalking among those who have experienced it at least once in their lifetime. Materials and Methods: A random sample of 228 healthy individuals aged 18-60 years was obtained and the members were asked to fill out a survey form about lifetime prevalence rate of sleepwalking. Results: The overall lifetime prevalence rate of sleepwalking was 7(16 of 228 participants). It was 10.4in males and 3.5in females; but the difference was not statistically significant (p=0.07). Conclusion: This study has shown that sleepwalking is common in the population. In view of the psychological effects of sleepwalking and the potential physical and legal problems associated with it; adequate efforts should be made for early detection and prompt management of the condition
