Sleep and the racing mind
sleep
It is 10pm and they are wired. Or it is 11pm and you are scrolling, unable to stop even though you are exhausted. The brain will not switch off for either of you.
What is happening in your brain
ADHD sleep problems affect 25 to 50 percent of people with ADHD. Three separate mechanisms are at work.
First, delayed sleep phase. The ADHD circadian rhythm runs later than neurotypical. Melatonin releases later. The body is genuinely not ready for sleep at the socially expected time.
Second, the default mode network. When external stimulation stops, the ADHD brain does not go quiet. It goes busy. Thoughts, worries, replays, plans, ideas all accelerate in the absence of something to focus on. A dark, quiet room is not calming for an ADHD brain. It is activating.
Third, stimulant medication can delay sleep onset further, depending on timing and individual response.
The result: a child lying in bed with their eyes open and their brain running, and a parent downstairs scrolling their phone for the same reason, unable to stop the input because stopping means facing the racing mind.
What is happening in your child's brain
Your child lying awake is not being defiant. Their brain will not stop. The racing thoughts are involuntary. Telling them to 'just close your eyes and relax' is asking them to do something their neurology will not allow. They need something for the brain to follow, an audiobook, white noise, a guided relaxation, that gives the default mode network a single channel to track instead of generating its own.
The dual-ADHD dynamic
Both parent and child may be awake late for the same neurological reason. The parent scrolls because stopping the phone means facing the racing mind. The child cannot sleep because stopping the day means facing the same thing. Both brains need a transition from stimulation to rest that does not involve going from full input to zero input.
What actually works
- Consistent wake time, even on weekends, matters more than bedtime. The circadian rhythm anchors to wake time.
- Audiobook on a sleep timer gives the brain one channel to follow instead of generating racing thoughts.
- Screen curfew 30 to 60 minutes before bed. The light and stimulation delay melatonin further. This applies to the parent too.
- Talk to the prescriber about melatonin timing. Low-dose melatonin 30 to 60 minutes before target sleep time can shift the circadian rhythm.
- If stimulant medication is contributing to sleep difficulty, the prescriber may adjust timing, switch formulations, or add a sleep-specific intervention.
Scripts
When they say they cannot sleep
"I know your brain is busy. Let us put a story on and you just listen. You do not have to try to sleep."
When you are doom-scrolling at midnight
"I am doing the same thing they do. My brain does not want to stop. Phone down. Audiobook on."
What your partner needs to know
They may not understand why bedtime takes so long or why you are still awake at midnight. What they need to know: this is not a discipline issue or a phone addiction issue. It is a neurological sleep-onset problem that both parent and child share. The fix is environmental and sometimes pharmacological, not willpower.
When to get more help
If sleep problems are severe, if the child is regularly getting less than the recommended hours, or if daytime functioning is significantly impaired by poor sleep, see the prescriber. Sleep is one of the most modifiable ADHD symptoms with the right combination of behavioural strategies, melatonin timing, and medication adjustment.
