Childhood disintegrative disorder

Childhood Disintegrative Disorder

Childhood Disintegrative Disorder (CDD), also known as Heller’s syndrome, is a rare condition characterized by late-onset developmental delays in language, social function, and motor skills. It typically affects children after 2–4 years of normal development. Unlike autism, where symptoms appear earlier, CDD is marked by significant regression in multiple areas such as vocabulary, play, and bladder control after a period of typical growth.

The exact cause is unknown, but neurobiological factors and possible genetic links are suspected. It is classified under Autism Spectrum Disorders but is extremely rare. Treatment includes behavioral therapies, special education, and medications to manage symptoms. Early intervention can help improve outcomes but complete recovery is rare.
