Sleep psychology

Have you ever wondered why your brain races at night while lying in bed? Even when you feel exhausted, sometimes it can be a challenge to quiet an active mind. Some neurodevelopmental disorders can make this issue worse. Believe it or not, there are also subconscious visual, or auditory cues that can either assist or prevent a person from achieving sleep. Sleep psychologists are experts in improving these problems- and you can consult with one here at Cook Children's Medical Center! These are individuals with a PhD in psychology, who have then done extra training in the field of behavioral sleep medicine. They can analyze a person's schedule, sleep environment, medical/developmental history and mindset at bedtime, and help to make a treatment plan that maximizes the duration and quality of sleep. They can help everyone from parents of young babies, to teenagers. Contact us if you think a sleep psychology visit could help a child in your family!

Symptoms and diagnosis of children's sleep disorders

Few things worry parents as much as a child who can't get restful sleep. Snoring, gasping or pauses in breathing can rob children of the rest they need and may even be signs of more serious problems. Children show symptoms of poor sleep differently than adults.

Children with poor sleep may exhibit:

  • Hyperactivity
  • Poor grades
  • Daytime sleepiness
  • Behavioral problems
  • Difficulty concentrating

To diagnose sleep problems, our sleep team evaluates your child's sleep history. In some cases, a comprehensive sleep study is needed to observe your child while he or she is sleeping. The results of your child's study will help us determine the appropriate interventions.

Barriers to good sleep include:

  • Sleep apnea
  • Insomnia
  • Sleep movement disorder
  • Circadian rhythm disorder

Preparing children for a sleep study

If your child is scheduled for a sleep study, you'll typically need to arrive at the Cook Children's Sleep Center around 6:30 p.m. This gives your child time to get comfortable with the environment before beginning the study. The study usually begins between 8 and 9 p.m.

We recommend that you follow your child's normal dinner and bedtime routine prior to arriving for the sleep study. Please plan to stay with your child in the Sleep Center during the procedure. Due to space limitations, we ask that only one parent or legal guardian stay with your child.

  • Bring comfortable sleepwear for your child
  • Bring diapers, formulas, snacks or other items your child normally needs
  • Bring any medications or treatments that your child normally takes
  • Bring any toiletries needed – showers are available to use prior to leaving
  • Feel free to bring your child's favorite items (toy, blanket) especially if your child needs it for sleep
  • NO CAFFEINE (coffee, tea, chocolate, etc.) after 1 p.m. the afternoon of the study
  • Children staying in the center for a day study are provided breakfast and lunch

The study takes about 8 hours and then you and your child may go home.

For the study, special non-invasive electrodes and monitors are attached to your child's face, head and arms prior to sleep. A polysomnography technician monitors your child's breathing, heart rate, oxygen level, sleep stages and chest and abdominal movement.

The technician tallies the results to pinpoint what irregularities were present and measures their severity.

Is my child a candidate?

Do you think your child has a sleep disorder? Take the assessment below.

  • Does your child snore loudly (louder than talking or loud enough to be heard through closed doors)?
  • Does your child often feel tired, fatigued, or sleepy during the daytime, even after a "good" night's sleep?
  • Does your child stop breathing during sleep?

If you answer "Yes" to any of these questions, we recommend you contact one of our sleep specialists to learn more.

In addition, some other symptoms for sleep disorders include:

  • Morning headaches
  • Irritability or moodiness
  • Poor concentration
  • Hypertension
  • Heartburn at night
  • Awakening frequently to urinate
  • Awakening with a sore throat
  • Frequently awakening with nasal congestion

About sleep apnea

Brief pauses in breathing during sleep are normal. But when breathing stops often or for longer periods, it's called sleep apnea.

When someone has sleep apnea, oxygen levels in the body may fall and sleep can be disrupted. You might think that only older people have sleep apnea, but kids and teens can develop it, too.

Sleep apnea happens when a person stops breathing during sleep ("apnea" comes from a Greek word meaning "without wind"). It is usually caused by something obstructing, or blocking, the upper airway. This is known as obstructive sleep apnea (OSA).

OSA is common, serious conditions that can make kids miss out on healthy, restful sleep. If left untreated, obstructive sleep apnea can lead to learning, behavior, growth, and heart problems. In very rare cases, it can even be life threatening.

Less commonly, sleep apnea can happen when someone doesn't get enough oxygen during sleep because the brain doesn't send signals to the muscles that control breathing. This is called central sleep apnea. Developmental abnormalities or neurologic diagnoses that affect the brain increase the risk of developing this type of apnea.


When we sleep, our muscles relax. This includes the muscles in the back of the throat that help keep the airway open. In obstructive sleep apnea (OSA), these muscles can relax too much and collapse the airway, making it hard to breathe.

This is especially true if someone has enlarged tonsils or enlarged adenoids (germ-fighting tissues at the back of the nasal cavity), which can block the airway during sleep. In fact, enlarged tonsils and adenoids are the most common cause of OSA in kids.

Risk factors for the development of OSA include:

  • A family history of obstructive sleep apnea
  • Being overweight
  • Certain medical conditions, such as Down syndrome or cerebral palsy
  • Defects in the structures of the mouth, jaw, or throat that can narrow the airway
  • A large neck (17 inches or more in circumference for men; 16 inches for women)
  • A large tongue, which can fall back and block the airway during sleep

Post-evaluation follow-up

At Cook Children's, teamwork goes beyond our walls. We work closely with your child's referring doctor, providing a follow-up plan and recommendations for treatment from a board-certified pediatric sleep specialist. Our goal is to work closely with you and your child's doctor to help ensure the best results and get your child back to the business of being a kid.


Health insurance companies cover the cost of testing for sleep disorders and often pay for the equipment necessary for prevention and treatment. Please be sure to check with your insurance provider for details about your coverage.

Simply login to your child's MyCookChildren's account, select 'Visits' and then the green 'eCheck-In' icon for your child's upcoming appointment. From there, you can fill out the necessary forms needed. This process from start to finish should take less than 20 minutes and will shorten your time in our office. Please note: the forms and questionnaires are specific to who your appointment is with and what is needed for that type of appointment. Even if you recently updated forms, there may be new items to complete that are specific for this appointment.
