ADHD and sleep: why do children with ADHD so often sleep so poorly?
Sleep disorders are one of the most frequent and most disabling comorbidities of ADHD. Between difficulties falling asleep, night-time waking and the chronic tiredness that results, insufficient sleep amplifies all ADHD symptoms during the day. Understanding this link is essential to act effectively.
The neurological link between ADHD and sleep
ADHD and sleep disorders share common neurological mechanisms. The circadian regulation system, which manages the sleep-wake rhythm, is often delayed in people with ADHD: their sleep hormone, melatonin, is secreted later in the evening, which naturally delays falling asleep. In addition, the ADHD brain, constantly seeking stimulation, struggles to make the transition to the calm needed to fall asleep. The flood of thoughts that rush in at bedtime is a very frequently reported experience.
How sleep disorders show up in ADHD
Sleep disorders linked to ADHD can show up in several ways. Difficulty falling asleep is the most common: the child takes 30 minutes, an hour or more to fall asleep even when tired. Frequent night-time waking and difficulty getting back to sleep. Restlessness in bed, restless legs. And in the morning, extreme difficulty getting up and prolonged morning confusion.
The impact of sleep deprivation on ADHD symptoms
Lack of sleep directly worsens all ADHD symptoms during the day. Attention is even harder to sustain. Impulsivity and irritability are amplified. Executive functions are even more impaired. And emotional regulation is even more fragile. A child with ADHD who sleeps poorly may show symptoms that seem much more severe than those of a well-rested child with ADHD.
Strategies to improve sleep
Several approaches can improve sleep in children with ADHD. A fixed, early bedtime kept every day, including at weekends. A predictable, soothing evening routine with no screens in the last hour before bed. A cool, dark and quiet bedroom. And when these measures are not enough, a medical consultation to assess whether melatonin supplementation, prescribed by the doctor who follows the ADHD, is appropriate.
