Sleep
Disrupted sleep can stop memories forming
A group of a children, some of whom who had disordered breathing, were asked to remember series of things. The learning session was given one day, then the children went to sleep, and the testing session was the following day. The children with disordered breathing did not remember as well as the other children. This shows that sleep problems have an impact on the developing brain and probably affects the way children learn.
Premmies are more likely to have breathing disorders and it is important to identify sleep problems early in childhood. Snoring is one symptom of disordered breathing.
