Advanced sleep phase disorder (ASPD), also known as the advanced sleep-phase type (ASPT) of circadian rhythm sleep disorder or advanced sleep phase syndrome (ASPS), is a condition in which patients feel very sleepy and go to bed early in the evening (e.g. 6:00–8:00 p.m.) and wake up very early in the morning (e.g. around 3:00 a.m.). ==Symptoms== People with ASPD are unable to stay awake until their desired bedtime and unable to stay asleep until their desired waking time. They will complain to a sleep clinician of early morning insomnia and falling asleep early in the evening. When someone has advanced sleep phase disorder their melatonin levels and core body temperature will cycle hours earlier than an average person.〔http://www.sleepdex.org/fasps.htm〕 These symptoms must be present for at least three months in order to be correctly diagnosed.
