Young Blind Child Melatonin Treatment Study
- Conditions
- Blindness
- Interventions
- Biological: Melatonin
- Registration Number
- NCT00688935
- Lead Sponsor
- Oregon Health and Science University
- Brief Summary
The primary goal of this study is to identify the presence of desynchronized circadian rhythms in 25 children by measuring melatonin secretion in serial blood or saliva samples, and to rule out any primary sleep disorders.
- Detailed Description
Subjects will complete 25-hours of hourly salivary, plasma sampling biweekly. Melatonin will be measured in urine, for children under the age of 3. Sleep and behavioral questionnaires will be completed by parents and/or teachers. This study involves an optional, 1-year melatonin treatment sub-study, in which the children will take 0.1 - 3mg daily. A second optional sub-study involves a study of the child's sleep through polysomnography, in order to identify possible sleep disorders.
