How is Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) Treated?

Due to the variety of symptoms that may be experienced by an individual with PPD-NOS, there is no one standard treatment for it. A thorough initial assessment will be required to assess which treatments and interventions would be most beneficial for the individual with PPD-NOS. The assessment should include:

  • current symptoms experienced
  • behavioural history
  • social ability
  • communication patterns
  • physical difficulties

Treatment for PDD-NOS is highly beneficial, especially if it is received in the pre-school years. The earlier the intervention starts for individuals with PDD-NOS the better the outcome will be for the individual.

Treatment and intervention must be individualised based on the information gathered in the initial assessment, and must be continually re-evaluated to ensure that they are appropriate to the individuals current abilities, age and interests.

There a variety of difficulties experienced by individuals with PDD-NOS across a number of areas of development. A multi-therapy approach will benefit those with PDD-NOS in helping them to improve and develop in more than one area of their development.

Treatments and interventions for individuals with PDD-NOS may include:

  • Specialist education - structured to meet each child's individual needs
  • Behaviour modification
  • Speech and Language Therapy
  • Physiotherapy
  • Occupational Therapy
  • Medication - normally used to alongside other interventions to treat specific symptoms such as anxiety, hyperactivity and extreme mood swings

The overall aim of treatment for PPD-NOS is to promote improved communication and social skills, whilst minimising the effects of behavioural problems. This in turn, will maximise the individual's ability to function in their everyday tasks to their highest potential.
