Delayed Sleep Phase Disorder (DSPD) Synonyms

Delayed Sleep Phase Disorder (DSPD) is a sleep disorder characterized by a persistent delay in the timing of the sleep-wake cycle. Individuals with DSPD typically have difficulty falling asleep and waking up at socially acceptable times, which can lead to chronic sleep deprivation and daytime sleepiness.

There are several synonyms used to describe Delayed Sleep Phase Disorder:

• Delayed Sleep Phase Syndrome (DSPS): This term is often used interchangeably with DSPD. It emphasizes the syndrome aspect of the disorder, highlighting the combination of symptoms and their impact on daily functioning.


• Nocturnal Delayed Sleep Phase Disorder: This term specifically refers to the delayed sleep phase occurring during the night, highlighting the nighttime aspect of the disorder.


• Circadian Rhythm Sleep Disorder, Delayed Sleep Phase Type: This term emphasizes the disruption of the body's internal circadian rhythm, which regulates sleep-wake cycles. It specifies the delayed sleep phase as the type of circadian rhythm sleep disorder.


• Delayed Sleep-Wake Phase Disorder: This term highlights the delayed wake-up time in addition to the delayed sleep onset, acknowledging the overall shift in the sleep-wake cycle.

It is important to note that while these terms are used interchangeably, they all refer to the same underlying sleep disorder characterized by a delayed sleep-wake cycle.

Individuals with DSPD may experience significant challenges in their daily lives, as their sleep patterns are misaligned with societal norms. This can lead to difficulties in attending school or work, maintaining social relationships, and overall reduced quality of life.

If you suspect you or someone you know may have Delayed Sleep Phase Disorder, it is recommended to consult a healthcare professional for proper diagnosis and management strategies.
