Advanced Sleep Phase Disorder
Description
Advanced Sleep Phase Disorder, ASPD, is a type of Insomnia. Its prime characteristic is that the major episode of Sleep for each day is advanced in relation to the desired clocktime, resulting in compelling evening sleepiness, an early sleep onset, and an awakening that is earlier than desired.
Prevalence
Advanced Sleep Phase Disorder is more prevalent in elderly persons.
Treatment of Advanced Sleep Phase Disorder
Fluorescent Lighting - Full Spectrum (Bright Light therapy) may alleviate Advanced Sleep Phase Disorder:
For the treatment of ASPD, the patient is exposed to a Light Box (as a means of delivering Bright Light therapy) in order to induce a phase delay that progressively delays bedtime until the desired bedtime is achieved. Bright Light Therapy for ASPD involves Bright Light exposure in the early evening (not at other times of the day).
