Childhood disintegrative disorder

Area of Science:

• Child Psychology
• Developmental Neuroscience
• Pediatric Neurology

Background:

• Theodor Heller first described dementia infantilis in 1908, noting severe mental regression in children after normal early development.
• Childhood disintegrative disorder (CDD) is a rare neurodevelopmental condition characterized by a significant loss of previously acquired skills.
• While sometimes associated with other medical conditions, these are not typical for CDD.

Purpose of the Study:

• To review recent cases of childhood disintegrative disorder.
• To provide updated information on nosology, epidemiology, and differential diagnosis.
• To discuss current understanding of aetiology, treatment, and outcome for CDD.

Main Methods:

• Review of recently published cases.
• Analysis based on diagnostic systems including ICD-9, ICD-10, and DSM-IV.
• Synthesis of information on various aspects of the disorder.

Main Results:

• Interest in CDD has significantly increased in recent years.
• The review consolidates current knowledge on CDD across multiple domains.
• Provides a comprehensive overview of the disorder's presentation and management.

Conclusions:

• Childhood disintegrative disorder remains a complex neurodevelopmental condition.
• Further research is needed to fully understand its aetiology and optimize treatment.
• Accurate diagnosis and management are crucial for affected children.
