Technical detail
Different sleep mechanisms need different help
Task switching and body-clock timing
Staying up because you cannot stop an activity is a behavioural delay. A delayed circadian rhythm means your body's sleep timing is later. Both can occur with ADHD, but they are not interchangeable.
A stopping cue addresses the transition into bed. It may not make you sleepy if your body clock is still promoting alertness. Explaining whether you sleep well when allowed a later schedule helps a sleep assessment distinguish the possibilities.

Insomnia can become self-maintaining
Repeated wakefulness and worry in bed can make bedtime feel like a test you expect to fail. CBT-I—cognitive behavioural therapy for insomnia—targets these sleep-related patterns. It is not a treatment for ADHD symptoms.
ADHD can make the treatment harder to implement: remembering to record sleep, following a changing schedule and stopping other tasks at the agreed time. Ask for support with those steps rather than accepting that another incomplete diary means the approach cannot help.
What adapted sleep treatment has shown
A 2019 pilot involving 19 adults with ADHD found improvement after a behavioural sleep programme based on CBT-I and adapted to ADHD-related difficulties. Without a control group, it cannot show that adaptations caused the improvement or outperform standard CBT-I.
The practical implication is to make sleep treatment usable, not to promise that one ADHD sleep routine will work for everyone. If remembering the plan improves but sleep does not, take that distinction back to the therapist.

Sleep loss can add to daytime ADHD difficulties
Poor sleep can worsen attention and everyday functioning, leaving less capacity to organise the following evening. Breaking that cycle may require treatment of insomnia, circadian timing or another sleep disorder, alongside ADHD support.
Medication can also affect the pattern. NICE recommends reviewing sleep changes during ADHD treatment. A prescriber can consider the timing and formulation; a sleep assessment can address problems that medication adjustments alone will not resolve.
