Sleep Enuresis (Nocturnal Bedwetting) As an infant learns bladder control, bedwetting usually goes away. Usually regular bedwetting disappears before the child is 5 years old. Regular bedwetting may occur in 40% of 4 year olds, 10 percent of six year olds, 5 percent of ten year olds, and 3 percent of 12 year olds.If psychological, psychiatric, neurological, and urological problems are ruled out, then the condition is called "primary enuresis". It is now thought that bedwetting has a genetic basis. It seems to run in families, and appears to be caused by a recessive gene. If both parents were late bedwetters as children, their children have as much as a 75% chance of being bedwetters. If one parent had this problem, then the children have about a 44% chance of also having bedwetting after 5 years old. This disorder is in the group known as other parasomnias. | |
