If you look at children with ADHD and ODD, almost half of them have trouble sleeping. In most cases, this is because of a combination of their ADHD, ODD, and the environment. However, there are other cases when a sleep disorder is actually causing ADHD or ODD.
Many children with ADHD or ODD do not get enough sleep. Overall, a child needs 9-11 hours of sleep a day. There are a number of things to check out to make sure common causes of insomnia aren’t missed.
When a person goes to sleep, he or she is supposed to breathe deeply and with little effort. If there is an obstruction so that the person can not breathe well, then they will not get enough sleep and awaken. In sleep apnea, a variety of factors are leading to obstructed airways during sleep so that everytime a person falls deeply asleep, their breathing is worse, and they awaken. Since they do not get deep unbroken sleep, they get psychiatric problems. They have trouble learning, are inattentive, irritable, and more difficult overall. In adults, they are usually tired out, but in children, it results in hyperactivity. About 2% of children have sleep apnea. Those at greatest risk are children who have the following features:
The reason this is important, is that the usual treatment for obstructive sleep apnea in Children is having your tonsils and/or adenoids removed. This results in 80-90% of the children improving.
If the clinical picture looks right, the best test is to do a full sleep study. This involves going to a sleep centre and having an all night recording of sleep while you have many things attached to you. This includes electrodes to monitor your brain waves, tubes to monitor your breathing, a finger mitten to monitory the oxygen in your blood, and another few wires to monitor your movement. Unfortunately, many children with psychiatric problems can not actually sleep with all this on. Secondly, there are very few centres for this and the backlog is quite long, as you can only do the test at night.
The second choice is a home sleep study. This includes quite a few less items. You have a finger mitten to monitor oxygen in the blood, movement monitors, and a tube to measure airflow in and out of the mouth. Most kids can sleep with this on. If this is consistent with sleep apnea, it is not necessary to do a full sleep study. The next step is to do go to a ENT surgeon to see if surgery is reasonable.
The third choice is oximetry. That is a finger mitten only. In difficult kids who are non-compliant, it is better than nothing. It if is very abnormal, it would make me want to pursue a home sleep study, if possible.
Sometimes people have sleep apnea and ADHD. Other times the diagnosis wasn’t carefully checked out before surgery.
This is a disorder where people have a hard time keeping their legs still. If they don’t keep moving their legs, they get unusual sensations in their legs. Sometimes it is pain, sometimes, aches, and other times it is some sort of vague discomfort. This goes away if they start moving. It is usually worse in the night. Often it is accompanied by Periodic Leg Movement Disorder, in which people’s legs make sudden movements in the night to such a degree that they wake themselves up.
So what does this have to do with ADHD?
If a person can not keep still because of Restless Leg Syndrome, it can look just like the hyperactivity of ADHD. Likewise, people who have both ADHD and Restless Leg Syndrome have a hard time getting to sleep. Many of them are sleep deprived because they can not get to sleep because of the restless legs and then they are awakened by periodic leg movements. This can result in bad tempered children who can not pay attention, common signs of ADHD.
What causes Restless Leg Syndrome and Periodic Leg Movement Disorder?
There are two common causes: low iron and genetics. It is very strongly inherited, especially if it appears in children. Almost always a child with these disorders will have a parent with them. Overall, they become worse, not better, with age. However, often times they will come and go in intensity over time.
ADHD and Restless Leg Syndrome run together
About 44% of children with ADHD also have signs of Restless Leg Syndrome. On the other hand, 26% of children with Restless Leg Syndrome have signs of ADHD.

This is a medication used for Parkinsons and Restless Leg Syndrome. It has also been used in children who have Tourette’s. It is quite well tolerated. It comes in a .05 mg size pill and the dose would be given an hour or so before sleep. There are no trials of its use in children

What this means is that rather than having the symptoms primarily in the evening, they start happening in the day. As a result you sometimes have to give more earlier in the evening.

so far in children, there do not seem to be any. The longest any child has taken these medications in the medical literature is 3 years.
