How is Childhood Disintegrative Disorder Diagnosed?

Childhood Disintegrative Disorder is commonly diagnosed when the parents/carers of achild notice the child's loss of previously acquired skills and as a result, contact their GP.

In general, the GP will perform a medical examination on the child to rule out any other medical conditions. If Childhood Disintegrative Disorder is suspected, the child will be referred to one or more specialists that may include a child psychiatrist, a neurologist or a paediatrician specialising in developmental and behavioural problems. Following a formal evaluation they will be able to make the differential diagnosis of Childhood Disintegrative Disorder.

Assessment tests performed may include some or all of the following:

  • Full medical history examination - extensive interview assessing when developmental milestones were reached, and the age at which previously acquired skills were lost
  • Neurological examination - to assess any abnormalities in the individual's brain or nervous system
  • Genetic tests - any inherited family conditions or diseases
  • Communication and language tests
  • Lead screening - to assess for lead poisoning as this can damage the nervous system and lead to developmental delays or
