Finalmente uno studio che speriamo metta a tacere tutti quelli che forzatamente vogliono far derivare l'autismo da cause genetiche o di neuroimanging

una volta per sempre lo studio di questi ricercatori iisraeliani che hanno messo al setaccio un database di circa mille immagini del cervello autistico hanno evidenziato che non vi sono sostanziali differenze fra cervello autistico e di normodotato

gli autori scrivono

" Individuals with ASD exhibited significantly thicker cortex than controls in several areas including the right and left occipital poles, left middle occipital sulcus, left occipital-temporal sulcus… [however] there were no significant differences in volumetric or surface area measures between groups. There were also no significant volumetric differences between groups in any of the subcortical areas."

Gli autori concludono

Haar et al. conclude that:

"There was no evidence for between-group differences in any measures of gross anatomy or in specific brain regions including the amygdala, hippocampus, most segments of the corpus callosum, and the cerebellum, which have been implicated in previous anatomical studies of ASD.

These results suggest that many of the previously reported anatomical abnormalities are likely to be of low scientific and clinical significance… anatomical differences between high-functioning ASD and control groups (aged 6 – 35 years old) are very small in comparison to large within-group variability.

This suggests that anatomical measures alone are likely to be of low scientific and clinical significance for identifying children, adolescents, and adults with ASD or for elucidating their neuropathology."

Per cui cari scettici mettete l'anima in pace....come la genetica nemmeno la neuroimaging può spiegare la lebbre del terzo millennio: l'autismo
