New Study Links Behavioral Problems with Childhood Sleep Disorders
Parents and doctors agree that sleep is vital for proper brain development in children; however, a new study links disrupted sleep with behavioral problems later in childhood. According to researchers at Albert Einstein College of Medicine at Yeshiva University, children who suffer from sleep-disordered breathing—snoring, apnea, and mouth-breathing—are more likely to have behavioral problems later in life. The study, published in the journal Pediatrics, tracked the sleeping patterns of children from the ages of 6 months to 5 ½ years old. Parents completed questionnaires regarding the type and severity of sleep-disordered breathing they witnessed. At 4 and 7 years of age, these same parents filled out questionnaires that focused on strengths and difficulties concerning their child’s behavior. The commonly used form assesses the following aspects of behavior:
- Inattention and hyperactivity,
- Emotional symptoms such as anxiety and depression,
- Peer problems,
- Conduct problems including aggression and rule breaking,
- Social cooperation with sharing, helpfulness, etc.
After controlling for different variables, researchers found that children who suffered from sleep -disordered breathing were “40% to 100% more likely to develop neurobehavioral problems by age 7…” Furthermore, the study found that children who suffered from more severe sleep-disordered breathing at 6 or 18 months were “40% to 50% more likely…to experience behavioral problems at age 7 compared with children without breathing problems.”Hyperactivity seemed to be the area most affected by sleep-disorder breathing; however, significant increases were evident in the other behavioral areas.[1]
The researchers believe this correlation is due in part to the effects sleep-disordered breathing have on a child’s developing brain. Research shows that the first three years of a child’s life are the most important for brain function. During this time span, a toddler’s brain is more active and open to learning than at any other stage of life. This openness, however, also increases the vulnerability to developmental problems. According to the researchers, sleep-disorder breathing can decrease the oxygen levels in an infant’s brain, thus increasing carbon dioxide in the prefrontal cortex—the area responsible for managing impulse control. Additionally, sleep-disordered breathing may disrupt the restorative processes of sleep and the balance of cellular systems, which may result in a child’s inability to effectively suppress certain behaviors and regulate their emotions and arousals.
While daunting, this study also provides hope. Armed with a new understanding, parents can immediately identify sleep-disorder breathing in their children and seek appropriate help.
