People with the male brain type, more autism

Looking at the face of the person, the other person usually will likely determine who is in front of him, male or female. The brains of people of different sexes also looks different, said the scientists, a group which was led by Christine Ecker (Ecker Christine) from Goethe University (Goethe University), Germany. According to Professor Ecker, men suffer from autism in 2-5 times more often than women, and this may be due in part to the characteristics of the brain. In the study, the research group found that in women, the brain which had more “masculine” structure, autism is diagnosed three times more often than women with “female” brain.

In the course of work, scientists tested depends on whether the likelihood of autistic spectrum disorders from the difference in anatomy of the brain. In particular, they measured the thickness of the crust. Earlier in another study, it became known that on average, the cortex is thicker in women than in men, and that the autistic thickness of the crust varies. Group Christine Ecker worked with 98 high-functioning autistic, of which half were male and half female, and 98 healthy people, of which female were 47 people. Experts have verified the absence of participants ‘ brain injuries, mental disorders, any genetic diseases that alter brain function (e.g. epilepsy). None of the participants did not take medications that could affect the outcome of the study.

All the people I worked with researchers, underwent brain scans using magnetic resonance imaging. Then Christine Ecker and her colleagues with the help of special software measured the thickness of cerebral cortex in each shot. After that they gathered this information in a common database, removing the names of the participants and mention their sex. The obtained data were graded based on the thickness of the cerebral cortex and other physical characteristics, and experts have suggested which images may belong to men and which to women.

The output was obtained scale “phenotypes of the brain.” 68.1% of female images had a greater number of signs of the female brain, and 74.5% of men the signs of male. Approximately 74% of the cases, the researchers could guess the woman belongs to the man or. When they again compared the MRI data with information about who they belong to, that found a link between “masculinity” of the brain and autism. Christina Eker noted that the risk of autism can be predicted if you pay attention to the structure of the brain. Despite the fact that the study involved only adults, this approach can work and have children.

It is too early to talk about the application of this diagnostic method in clinical practice.
