An edition of the science journal, Nature, focuses on autism (click here).

The New Zealand High Court has knocked back the Ministry of Health, ruling in favour of nine parents of disabled adults, saying they are eligible for financial support from the ministry.

A group of nine parents of disabled adult children took the Government to the Human Rights Tribunal last year, arguing that it was unfair the Ministry paid carers only if they were not related to the patient.

The tribunal found the ministry had discriminated against the parents, but the ministry appealed the decision to the High Court.

Ten minutes in a brain scanner could be all it takes to diagnose autism. So says Christine Ecker at the Institute of Psychiatry, UK, who has developed software that identifies the anatomical signatures of the condition.

Ecker's team carried out MRI scans on the brains of 20 adult males with autism, 20 with attention-deficit disorder and 20 healthy controls. They used a machine-learning tool called a support vector machine (SVM) – which analyses data and identifies patterns – to identify key differences between the groups, such as in the cortical folding and curvature of the brain.

Although autism is a highly heritable neurodevelopmental disorder, attempts to identify specific susceptibility genes have thus far met with limited success¹. Genome-wide association studies using half a million or more markers, particularly those with very large sample sizes achieved through meta-analysis, have shown great success in mapping genes for other complex genetic traits.
