How is Pervasive Developmental Disorders Diagnosed?

If symptoms of Pervasive Developmental Disorder are apparent, it is important that the child is fully assessed by a paediatrician or child psychologist as early as possible.

There are no specific tests that can confirm whether a child has Pervasive developmental Disorder; diagnosis is normally based on the child's level of development, their speech ability and behaviour, as well as an assessment of their play and ability to socialise.

The parent/carers of the child play a key role during diagnosis as they are often the ones who can provide the appropriate information with regards to changes in symptoms and developmental milestones.

In general, the child must have impairments in the following areas for a diagnosis of PDD:

  • Speech
  • Social interactions
  • Repetitive behaviours

Identifying PDD will involve a range of healthcare professionals, who can assess and identify problems in specific areas of development. Professionals which will usually be involved include:

  • Physiotherapists
  • Speech and language therapists
  • Occupational therapists
