What Is Circadian Rhythm Disorder?
A circadian rhythm disorder occurs when the internal clock regulating sleep and wakefulness is weakened or when it is misaligned with a person's desired sleep period. Sleep specialists use a diagnostic system called the International Classification of Sleep Disorders (ICSD). The diagnostic category is established by a panel of experts who take into account available research and clinical experience.
