Advanced Sleep Phase Disorder

Advanced Sleep Phase Disorder (ASPD) is a sleep disorder characterized by an abnormally early circadian rhythm. People affected by ASPD tend to fall asleep earlier in the evening and wake up earlier in the morning, usually hours before their desired sleep and wake times. ASPD can have a significant impact on quality of life, as it can cause difficulties in maintaining social obligations, reducing important family time and impairing occupational performance. Treatment for ASPD usually involves chronotherapeutics, such as timed light exposure, bright light therapy, sleep hygiene, and in some cases, melatonin supplementation. Recognizing and treating ASPD can help to improve quality of life and reduce the associated impairments.
