ADHD and Sleep: Why They're Connected

ADHD and sleep are connected in both directions. Adults with ADHD often take longer to fall asleep, sleep less soundly and wake up later, and poor sleep can itself cause ADHD-like trouble focusing. Stimulant medication can also make sleep harder. That's why sleep belongs in every ADHD conversation with your provider.

At Padgett Medical Center in Tampa, the new patient ADHD visit is $169 when you book online with a card on file, 35% off the regular $260. Nothing is charged when you book.

How does ADHD affect sleep in adults?

Adults with ADHD often take longer to fall asleep and have more trouble staying asleep, even when they don't think of it as insomnia. Many also lean toward being night owls, with a body clock that runs late.

A review of sleep research in adult ADHD found that ADHD in adults is associated with a longer time to fall asleep, whether or not people report insomnia, disturbed sleep, later waking and greater 'eveningness', a preference for later hours. It also found a later dim light melatonin onset, the evening rise of the body's sleep hormone. The authors described the pattern as typical of delayed sleep phase disorder, in which the body clock runs later than a regular schedule.

In daily life that can mean lying awake past midnight, struggling with early alarms and feeling foggy through the morning, then more alert late at night.

Can poor sleep look like ADHD?

Yes. Sleep problems can cause trouble concentrating and forgetfulness that look like ADHD, which is why a provider asks about sleep during an evaluation.

The CDC lists sleep problems among the health issues that can cause symptoms like ADHD or are often present with it, and says an exam may be needed to rule them out. The National Heart, Lung, and Blood Institute recommends 7 to 8 hours of sleep a day for adults. If you regularly get far less, improving sleep may be part of understanding your focus. Poor sleep doesn't rule ADHD out, though; both can be present. What to expect at an adult ADHD evaluation explains how other explanations are considered.

How can ADHD medication affect sleep?

Stimulant medication can make it harder to fall asleep or stay asleep. MedlinePlus lists difficulty falling asleep or staying asleep among the side effects of methylphenidate (Ritalin, Concerta).

Timing matters. MedlinePlus advises asking your doctor or pharmacist how late in the day you can take a missed dose so it won't disrupt your sleep. The same sleep review found that stimulant treatment was associated with a later body clock. If your sleep changes after you start or change a medication, tell your provider. Don't move, skip or change a dose on your own; your provider decides on any change. For how the medication classes compare, see adult ADHD medication options.

What sleep habits help when you have ADHD?

The habits that help most are a steady schedule, a quiet hour before bed and limits on caffeine, alcohol and late screens. These are general sleep recommendations, and they apply with ADHD too.

The NHLBI's healthy sleep habits include going to bed and waking up at the same time every day, with no more than about an hour's difference on weekends; using the hour before bed for quiet time, away from bright screens; avoiding caffeine, nicotine, alcohol and heavy meals close to bedtime, since caffeine's effects can last up to 8 hours; keeping the bedroom quiet, cool and dark; getting outside and being active during the day; and keeping naps to 20 minutes.

A few tweaks can make those habits easier to keep with ADHD. Set an alarm for when to start winding down, not just for waking up. Charge your phone outside the bedroom. Lay out what you need for the morning the night before, so fewer decisions wait for a tired brain.

When should you tell your provider about sleep?

Tell your provider about sleep at your evaluation and at every follow-up, and sooner if it changes after you start or adjust a medication. Sleep is part of your treatment, not a side topic.

Useful notes include your usual bedtime and wake time, how long it takes to fall asleep, how often you wake, how you feel during the day and your caffeine and alcohol use. Mention loud snoring or strong daytime sleepiness too.
