Yes, there is a recognised DSPS ADHD connection, with many individuals who have ADHD also experiencing delayed sleep phase syndrome. DSPS is a circadian rhythm disorder in which a person’s natural sleep pattern is shifted later than is typical. This means they may not feel sleepy until very late at night and often struggle to wake up in the morning.

Why DSPS and ADHD Overlap

Research shows that ADHD sleep issues are common, and DSPS is one of the most frequent. People with ADHD may have differences in melatonin production or circadian rhythm regulation, making it harder to align with conventional schedules. This delayed sleep pattern can lead to Chronic sleep deprivation when early wakeups are required, daytime fatigue, reduced concentration, and worsening of core ADHD traits, such as impulsivity and poor emotional regulation.

Managing Delayed Sleep Phase in ADHD

Addressing delayed sleep phase alongside ADHD often involves structured interventions such as:

Light therapy in the morning to reset the circadian rhythm.

Melatonin supplements taken in the evening to encourage earlier sleep onset.

Consistent bedtime routines to reinforce healthy patterns.

Because DSPS can intensify ADHD symptoms, managing both together is crucial for better daily functioning.

Recognising the DSPS ADHD connection highlights how closely sleep, and attention regulation are linked. By treating delayed sleep phase as part of ADHD care, individuals can improve focus, mood, and overall wellbeing.
