4. Identify candidate gene-environment interactions using model systems
§ Determine the reasons why some individuals with specific genetic and neurodevelopmental syndromes (e.g. tuberous sclerosis, chromosome 15 abnormalities and fragile X) develop autism spectrum disorders, whereas others with the same condition do not.
5. Investigate the extent and basis of causal overlap with other complex neuropsychiatric conditions:
§ Use genetic and epidemiological methods to clarify the extent to which autism spectrum disorders are associated with other neuropsychiatric, developmental and medical disorders (e.g. language disorders, learning disability, epilepsy, hyperactivity, motor tics, Tourette's syndrome, obsessions and compulsions, depression, hypomania, psychosis, challenging behaviour) and determine why these disorders co-occur.
6. Advance therapeutics:
§ Identify targets for primary and secondary prevention and symptomatic relief and utilise this evidence to develop new and more effective therapeutic approaches.
§ Design treatment trials that are informative with respect casual processes
§ Test the efficacy and side effects of treatments.
7. Improve clinical services and service delivery:
§ Translate research advances into clinical developments (e.g. genetic counselling services, brain imaging protocols).
§ Develop methods of service implementation and role out developments (e.g. early home-based interventions).
