What happens when a child suddenly loses skills they once had? Childhood Disintegrative Disorder (CDD), also known as Heller's syndrome, is a rare developmental disorder that can be both puzzling and distressing. Imagine a child who has been developing normally, hitting all the expected milestones, and then, out of nowhere, starts to regress. They might lose their ability to speak, interact socially, or perform motor tasks they once mastered. This sudden and severe loss of skills typically occurs before the age of three. While CDD shares similarities with autism spectrum disorder, it stands out due to its dramatic regression. Understanding CDD involves exploring its symptoms, causes, and the impact it has on both the child and their family.

Key Takeaways:

  • Childhood Disintegrative Disorder (CDD) is a rare condition that causes children to lose previously acquired skills, such as language and social interaction, leading to significant developmental delays.
  • Early diagnosis and intervention are crucial for improving the quality of life and developmental outcomes for children with CDD. Healthcare providers play a key role in recognizing and managing this disorder.
