Sleep deprivation affects children differently than adults

Thursday, December 1st, 2016 by admin

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.

Brainwashed?!

Tuesday, October 22nd, 2013 by admin

This past week, researchers at the University of Rochester released study results indicating that while the brain sleeps, it clears out harmful toxins. This study was conducted in mice; however, the implications are that this cleansing process may actually reduce the risk of Alzheimer’s in adults.

The flow of cerebrospinal fluid in the brain increases quite dramatically during sleep. This increase in flow helps wash away the waste proteins that build up between brain cells. Scientists discovered that when mice went to sleep, their brain cells shrank, making it easier for fluid to circulate. Upon waking, the brain cells enlarged again and the flow between cells slowed to a trickle. Dr. Nedergaard, an author of the study, said it was like opening and closing a faucet; that the differences between sleep and wake were that dramatic.

This process during slumber is important, because the waste proteins getting washed away are toxic to brain cells. It could explain why prolonged lack of sleep can cause problems with brain functioning, like attention and memory. This process also takes a lot of energy, which is why it happens most efficiently while we sleep.

Even though this brain-cleaning process has only been observed in rats and baboons, it could offer a new way to understand human brain diseases like Alzheimer’s. One of the waste products removed during sleep is beta amyloid, the substance that forms sticky plaques associated with Alzheimer’s.

These findings are yet another reminder that good sleep is important and vital to our health. In addition, Brainjogging can also play a role in better brain health. Children are not the only clients to benefit from Brainjogging! Older adults, who have been experiencing memory loss and foggy attention, come to Camp Academia for help. Instead of spelling words and mathematical formulas, individualized Brainjogging word lists include family names, addresses, favorite poems, literary passages and hobby-related vocabulary. It still takes just 5-7 minutes twice daily to make a noticeable difference in more reliable brain functioning!
