Department of Developmental Disability Neuropsychiatry (3DN)

Media & Events

Welcome to the Department of Developmental Disability Neuropsychiatry

The Department of Developmental Disability and Neuropsychiatry, also known at 3DN, was set up by the Chair of Intellectual Disability Mental Health to address the poor mental health experienced by people with an intellectual disability (ID). 

This is an important issue for people with an ID and their advocates because compared to the general population they are:

  • 2-3 times more likely to experience common mental health disorders,
  • more likely to be exposed to risk factors associated with poor mental health (e.g. poor physical health), and
  • are less likely to access mental health care.


It is also important because, as a signatory to the Convention on the Rights of Persons with Disabilities, Australia has agreed to address the inequities that exist within our healthcare system for people with an ID.

As such, 3DN aims to develop research, education and training opportunities, and services that improve the mental health and quality of life of people with an ID. We do this by working with:

  • people with an ID,
  • their advocates,
  • State and Federal government,
  • health and mental health organisations, and
  • disability organisations.


3DN Strategic Plan 2013-2015

3DN is pleased to announce our new Strategic Plan for 2013 to 2015. The Strategic Plan will be our guiding framework for the next three years and outlines our vision for the highest attainable standard of mental health and wellbeing for people with an intellectual or developmental disability.

We aim to make a significant contribution to achieving this vision by improving mental health policy and practice.

The Strategic Plan outlines our activity in the areas of consultancy, building capacity in the sector, and research. In the Strategic Plan, these three areas of activity are mapped against the levels of impact of our work - people, the workforce, systems and policy.

Please click here to view the Plan. We hope you enjoy reading it and keep in touch with our work.



The e-Learning site is an interactive education resource for everyone with an interest in intellectual disability mental health. This site is the result of a collaboration between the Department of Developmental Disability Neuropsychiatry, the NSW Department of Family and Community Services (Ageing, Disability and Home Care), and the NSW Ministry of Health.

The idea for this resource grew out of a series of local workshops run by 3DN and the content was developed by a team of medical, mental and allied health professionals. The team has clinical, administrative and research experience and represents the health, welfare and disability sectors. People with an intellectual disability also had a role in developing content for the site, as you will see when you progress through the modules.
