If you have kids, then you know the horror of a sleep-deprived child!  We also know that we as adults need a good nights sleep to be our most productive.  However, a new study shows that sleep-deprivation affects children differently than adults.

“The process of sleep may be involved in brain “wiring” in childhood and thus affect brain maturation,” said Salome Kurth, Ph.D., first author of the study published in Frontiers in Human Neuroscience.   A lot of important neural connections are made when children sleep.   According to his recent study,  when adults are sleep-deprived, damage is seen in the frontal regions of the brain.  However, when children do not get needed sleep, damage occurs in the parieto-occipital (language, math, spacial relationships, vision) region, in the back of the brain.  This correlates with the fact, that in childhood, sleep is needed for development of the posterior regions of the brain.

After staying up too late, both children and adults need a period of deep sleep to recover.  This recovery phase is characterized by an increase in an electrical pattern called slow-wave activity, which can be measured with a non-invasive technique called an electroencephalogram. With a large number of electrode channels distributed across the scalp, this method also detects which brain regions show more slow-wave activity than others.

Kurth and his colleagues at the University of Zurich, measured the deep sleep patterns of two groups of children.  One group had a  normal night’s sleep.  The other had been kept up past their bedtimes by reading and playing games with them.   After only getting half of a night’s worth of sleep, the children showed more slow-wave activity towards the back regions of the brain, the parieto-occipital areas. This suggests that the brain circuitry in these regions may be particularly susceptible to a lack of sleep.

In addition, the study also showed a correlation between deep sleep activity and myelin content in the brain.  Myelin is a fatty microstructure of the brain’s white matter that allows electrical information between brain cells to travel faster. It can be measured with a specific magnetic resonance imaging technique.  The higher the content of myelin in a region of the brain, the more the sleep loss effect is similar to adults.  Regions of the brain that are undergoing development, will be more affected by sleep deprivation.

How can we be sure that our child is getting enough sleep?

Creating the right bed time routine for your child can be tricky.  But if you make it simple and clear, it can be done!

• Set up a routine from start to finish and be consistent in following each step.
• Have your child start his bedtime routine at the same time each day.
• If your child responds to visual cues, a chart might help!
• Avoid video games.
• Some children have food sensitivities that can irritate their digestive system and prevent them from getting a good night’s sleep.  Stop all snacks and meals 2 hours before bedtime if you think that might be the case.
• Keep a journal to see what worked and what didn’t.

Children love predictability!  A bedtime routine often leads to better behavior because our kids will get needed sleep as well as know what to expect each day.
