Asperger's syndrome: the causes

The causes of Asperger's syndrome are still very mysterious. The only thing that is certain is that they are multifactorial.

Research on Asperger syndrome has often been linked to research on Autism Spectrum Disorder (ASD). There are therefore few specific studies on the causes of Asperger's syndrome per se. However, it is very likely, like autism, that genetic involvement is strong. There are also many people with Asperger Syndrome in the same family. This does not exclude the environmental part, whose importance is difficult to grasp.

Some causes, previously suspected, were eventually invalidated by research: gluten intolerance, vaccination against measles, mumps and rubella, or psychological characteristics of the family. However, the implications of these causes remain debated. Indeed, we now know that the environment - family, food, pollution, etc. - plays an important role in the expression of genes. Some people with Asperger's syndrome say they feel better with a gluten-free diet.

But no research has shown that hypersensitivity or intolerance to gluten - and Asperger's syndrome are really related. In addition, American researchers have assumed that hyperacusis and tinnitus are more common among people with Asperger's syndrome, and questioned whether these symptoms explained the difficulties of social interaction.

Not to mention causes as such, neuroscientific research has demonstrated several differences in brain function between Asperger's and non-Aspergers. Using electroencephalograms, researchers reported differences in electrical activity at the frontal lobes. Structural "deficits" have also been observed within the amygdala and associated limbic structures. These could explain the difficulty of recognition of emotions shared by many people with Asperger syndrome.
