Question: Tower studied the efficacy of scheduled nap therapy on the episodes of sleep attacks and symptom severity among 25 narcoleptic patients from a sleep disorder clinic in Los Angeles. The therapy consisted of three scheduled 10-minute naps daily at 10 a.m., 1 p.m., and 3 p.m. Subjects maintained daily sleep diaries in which they recorded time and duration of sleep episodes for 2 weeks prior to treatment, during the two-week treatment period, and for 2 weeks following treatment. Research assistants who were unaware of the study purpose or the treatment coded information in the diary for number of sleep episodes daily and total amount of time spent sleeping daily. The severity of common narcoleptic symptoms (e.g., sleepiness, sleep paralysis) was also assessed through a questionnaire administered prior to and following treatment. Treatments occurred in a sleep laboratory, with all participants reporting at 9 a.m. and being given guidance on scheduled napping. Tower found that neither the frequency of sleep attacks nor the severity of narcoleptic symptoms improved over the course of the study. There were also no changes in amount of sleep or number of sleep episodes. She concluded that the study did not yield evidence supporting the effectiveness of the intervention, but recommended further research using a different research design and a larger sample.
