Development
Sleep-related movements are commonly seen in children, especially infants. However, the majority of these movements stop as the child ages. Some 66% of infants of 9-months show RMD-like symptoms compared to only 8% of 4 year olds. The disorder is closely associated to mental retardation or other psychiatric disorders like Autism. More recent studies have shown there is a strong link between prolonged RMD and ADHD .

Famous quotes containing the word development:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
“The highest form of development is to govern one’s self.”
—Zerelda G. Wallace (1817–1901)
