NICHCY's Connections pages are designed to put you in quick contact with information that's readily available on the Internet. We're pleased to offer this particular resource page to connect you with sources of information about children and youth with Childhood Disintegrative Disorder. This page is part of a "suite" of pages on disorders along the autism spectrum. The suite includes:
- Asperger Syndrome
- Rett Syndrome
- Childhood Disintegrative Disorder (you're here!)
- PDDNOS, Pervasive Developmental Disorder Not Otherwise Specified
Why a Suite of Different Pages?
Why are we designing these resources pages as part of a suite? How and why are they connected to one other? The answer lies in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM is the guide typically used by physicians and mental health professionals to diagnose the five disorders listed above. Published by the American Psychiatric Association, the latest edition of the DSM came out in 2000 and is known as the DSM-IV-TR (meaning the fourth edition, text revision). It lists the symptoms associated with each of the five disorders. Most importantly, it also groups all five disorders under the "umbrella" category of Pervasive Developmental Disorders, or PDD. Why? Because these disorders share in common the following characteristics: impairments in social interaction, imaginative activity, verbal and nonverbal communication skills, and a limited number of interests and activities that tend to be repetitive.
The Umbrella Category: PDD
The term Pervasive Developmental Disorders was first used in the 1980s to describe a class of disorders with similar symptoms or characteristics. The term occasionally causes some confusion, because one of the disorders underneath the umbrella has a very similar name---PDDNOS (Pervasive Developmental Disorder Not Otherwise Specified). As a result, PDD and PDDNOS are sometimes used interchangeably. A doctor, for example, may tell a parent that his or her child has PDD. This may stir up confusion further down the diagnostic and treatment road, because PDD actually refers to the overall category of disorders. It's not a diagnostic label. Some doctors, however, are hesitant to diagnose very young children with a specific type of PDD, such as Autistic Disorder or Asperger's Syndrome, and therefore only use the general category label of PDD. In other cases, the doctor may say PDD as a shorter way of talking about PDDNOS.
To avoid this confusion, our suite of pages will use the term PDD to refer to the overall category of Pervasive Developmental Disorders and the term PDDNOS to refer to the specific disorder, Pervasive Developmental Disorder Not Otherwise Specified.
This particular page connects you with resources on Childhood Disintegrative Disorder.
The resources we've listed aren't intended to be exhaustive of those available. We'll be adding to this page throughout the year, so you may wish to check back every now and again to see what's new!
- The DSM diagnostic criteria for CDD.
Without explanation or elaboration, here's the criteria for Childhood Disintegrative Disorder as it appears in the DSM-IV-TR.
- Contrast DSM criteria for CDD with the other PDD disorders.
NICHCY offers a briefing paper on PDD that includes an overview to the umbrella category under which mental health professionals have placed Childhood Disintegrative Disorder. This includes the DSM criteria that are used to diagnose the disorder. You may also find it helpful to see these criteria contrasted with those used to diagnose the four other disorders under the PDD umbrella.
- A description of CDD.
The Yale Developmental Disabilities Clinic offers comprehensive, multidisciplinary evaluations for children with social disabilities, usually focusing on the issues of diagnosis and intervention. The above article includes a description of CDD, its clinical features and diagnosis, history, its course and prognosis, its etiology, and a case illustration.
- From the medical encyclopedia at Medline Plus.
Read Medline's description of CDD, including definition, causes, risk factors, symptoms, signs and tests, treatment, prognosis, and complications. Medline is a service of the National Library of Medicine.
- A brief description of CDD and a comparison of DSM criteria with other criteria used internationally.
This site provides information and connection on all sorts of mental health matters. From the link above, the "disorders" page, you can scroll down to Childhood Disintegrative Disorder and see what they have to offer. One interesting link takes you to the ICD-10 criteria for diagnosing mental disorders (ICD-10 Classification of Mental and Behavioural Disorders
World Health Organization, Geneva, 1992).
- Want to know more about the DSM-VI-TR, and how it was compiled?
Visit the American Psychiatric Association's DSM-IV-TR Library, located at the link above.
We were unable to identify research being conducted that focuses specifically or exclusively upon childhood disintegrative disorder. We've listed only a few resources below that you may find useful when investigating research on the disorder. However, because CDD is under the umbrella of PDD, as is autism, you may find it helpful to know what research is being conducted on the autism spectrum and what it's revealing.
- Autism and PDD research at the Yale Child Study Center.
Visit the Center to find out what research they're conducting on autism and PDD.
- Want to know how to evaluate research studies?
OAR, the Organization for Autism Research, offers a guide, entitled Life Journey Through Autism: A Parent's Guide to Research, to help parents become "savvy" about finding and consuming information on autism, with special emphasis upon examining the research. Sources of this information are presented. The science model is then explained, along with a framework for evaluating research studies and the current state of autism research.
And since so little is actually written about CDD exclusively, we thought you'd want to know about these publications in professional journals.
