There is growing evidence of a strong DSPS ADHD relation, though delayed sleep phase syndrome (DSPS) is not officially classified as a core symptom of ADHD. DSPS is a circadian rhythm disorder in which a person’s internal body clock is shifted later than typical, leading to late bedtimes and difficulty waking up on schedule. While ADHD and DSPS are separate conditions, they often occur together and influence each other’s symptoms.
Why DSPS and ADHD Overlap
Research shows that people with ADHD are more likely to experience circadian rhythm disorders such as DSPS. This overlap may be due to:
- Differences in melatonin release, delaying the body’s natural sleep signals.
- Hyperactivity and racing thoughts make it harder to wind down at night.
- Irregular routines, which reinforce late sleep cycles.
These factors mean many individuals with ADHD end up going to bed late, struggling with mornings, and experiencing chronic sleep deprivation.
Impact on ADHD Symptoms
When DSPS is present, it can intensify ADHD symptoms such as inattention, irritability, and poor executive functioning. Lack of restorative sleep makes it harder to regulate mood and focus, creating a cycle where ADHD and DSPS feed into one another.
Recognising the DSPS ADHD relation is key to effective management. Treating DSPS through strategies like light therapy, melatonin, and structured routines can improve both sleep quality and ADHD related challenges.
