Thank you for posting this article which I forwarded to my niece. She recently had a sleep study done on her five year old son that did not show OSA but he had many leg movements and arousals. He has been using an oral appliance for several months that appears to be helping as the night time awakenings have lessened and he no longer has any incidents of waking up gasping/coughing. She is continuing to work with a pediatric sleep physician along with the dentist but this article really highlights that the reasons contributing to poor sleep may be varied but all have negative impacts on our health and need to be addressed.
