Nevertheless, expectations of the creation of diagnostic methods continue to emerge. Scientists in the UK for example, a recent finding that brain MRI scans can also diagnose autism in adults.
The research of Dr. Christine Ecker, Lectures and neurological development of forensic science from London's Institute of Psychiatry and Neuroscience journal published, said brain scans (scan) during the 15-minute MRI can identify autism spectrum disorders (ASD) with an accuracy of 90 percent.
This is evidenced by the accuracy of MRI brain scans of 20 people previously diagnosed with autism.
"Our study offers a 'proof of concept' to describe the differences in gray matter (gray matter) on the multidimensional complex of ASD," says Ecker.
In an experiment, magnetic resonance imaging are reconstructed into 3-D images and analyzed using computer software that is programmed to find the structural changes in the gray matter of the brain by measuring the area associated with behavior, language and vision. Changes seen in the shape and thickness to the point of this disorder.
"The ability to diagnose ASD based on objective biological tests that more quickly identify patients who need treatment than current methods that only depend on the personality traits," said Ecker.
The study followed 20 people with autistic men aged 20 to 68 years and 20 respondents of non-autistic. Participants were tested in the conventional labia first and then their brains will be scanned to compare the two techniques.
The result, an MRI scan to identify patients with ASD by 90 percent accuracy, while 80 percent of non-autistic participants successfully classified,
Ecker warned, this technique relies heavily on the characteristics of the sample of participants. In this case, an MRI scans only works so well on adults with autism and Asperger syndrome.
Until recently, MRI scans are still used as a research tool and not a tool to diagnose.
