childhood disintegrative disorder

[¦chīld‚hu̇d dis′in·tə‚grād·iv dis‚ȯrd·ər]
(psychology)
A condition occurring in 3- and 4-year-old children that is characterized by unequivocally normal development in the first several years of life, followed by a marked developmental regression (a child who previously had been speaking in sentences becomes totally mute), and various autistic features develop. Also known as Heller's syndrome.

Autism, Asperger disorder, childhood disintegrative disorder, and PDDNOS all are collectively described as autism spectrum disorders.
Childhood disintegrative disorder (CDD) is a rare pervasive developmental disorder (PDD) which is characterised by a marked regression in multiple areas of development after 2 years of normal development and before 10 years of age.
For example, the new autism spectrum disorder (ASD) now encompasses the previous DSM-IV autistic disorder (autism), Asperger's disorder, child hood disintegrative disorder, and pervasive developmental disorder not otherwise specified.
The disturbance is not better accounted for by Rett's disorder or childhood disintegrative disorder.
Using DSM-IV, patients could be diagnosed with four separate disorders: autistic disorder, Asperger's disorder, childhood disintegrative disorder, and the catch-all diagnosis of pervasive developmental disorder not otherwise specified.
ASD is now an umbrella term that encompasses autism, Asperger syndrome, pervasive developmental disorder not otherwise specified, childhood disintegrative disorder, and Rett syndrome.
Other conditions along the spectrum include the milder Asperger syndrome, childhood disintegrative disorder and pervasive development disorder not otherwise specified (PDD-NOS).
Thus, the prior diagnoses falling trader pervasive developmental disorders of autistic disorder, Asperger's syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (PDD NOS) are now all called autism spectrum disorder.
The DSM-5, published in 2013, redefined the autism spectrum to encompass the previous (DSM-IV-TR) diagnoses of autism, Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), childhood disintegrative disorder, and Rett syndrome.
Thus, the prior diagnoses falling under pervasive developmental disorders of autistic disorder, Asperger's syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (PDD NOS) are now all called autism spectrum disorder.
The American Psychiatric Association is expected to create a new category in its diagnostic definitions: "Autism spectrum disorder" would include several diagnoses that used to be listed separately, including autistic disorder, Asperger's disorder, childhood disintegrative disorder and pervasive developmental disorder.
2] The conditions included under the ASD label vary slightly between the three diagnostic systems commonly used in China -the 3rd edition of the Chinese Classification and Diagnostic Criteria of Mental Disorders; [3] the 10th edition of the International Classification of Diseases (ICD-10) [4] and the 4th edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) [5] In all three diagnostic systems, ASD includes autism, atypical autism, Rett syndrome, childhood disintegrative disorder, Asperger syndrome, and pervasive developmental disorder not otherwise specified (PDD-NOS).
