Childhood Disintegrative Disorder is a severe condition in which a child will develop normally until age 3 or 4, then rapidly lose already learned skills such as communication skills, motor ability, nonverbal behaviors, and social skills over the course of a few months (Zieve, 2012). Theodore Heller originally described the condition and reported his findings in 1908. It has been only recently that the disorder has been recognized as a clinical condition and was included into the DSM-IV in its 1994 release (Westphal, 2014).
CDD is an uncommon condition. Since Heller's original description in 1908, there have been approximately 100 reported cases in literature (Volkmar, 2005). In case by case studies, the prevalence has shown to have about an equal sex ratio, although more recent studies have shown that CDD is slightly more common in males (Barber National Institute, 2013).
Symptoms of Childhood Disintegrative Disorder consist of: a lack or delay of spoken language, loss of social skills, loss of bowel and bladder control, overall loss of communication skills, both verbal and nonverbal, loss of motor skills, inability to begin or maintain a conversation, and p...
