Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Gut-brain axis is the sole cause of ASD. | While there is evidence to suggest that disruptions in the gut-brain axis may contribute to some symptoms of ASD, it is not the only factor involved in its development. Other factors such as genetics and environmental influences also play a role. |
| All individuals with ASD have gastrointestinal issues. | While gastrointestinal issues are more common among individuals with ASD compared to neurotypical individuals, not all individuals with ASD experience these issues. Additionally, gastrointestinal issues can be present in other conditions as well and should not be used as a sole diagnostic criterion for ASD. |
| Probiotics can cure or treat autism. | There is currently no cure for autism and while probiotics may help alleviate some gastrointestinal symptoms associated with it, they cannot treat or cure autism itself. It’s important to consult a healthcare professional before starting any new treatment regimen for an individual with ASD. |
| The gut-brain axis only affects behavior in children with autism spectrum disorder (ASD). | The gut-brain axis has been shown to affect behavior in both neurotypical individuals and those on the spectrum alike; however, research suggests that this connection may be stronger among those on the spectrum due to their increased susceptibility towards certain types of bacteria found within their microbiome. |
| A gluten-free/casein-free diet will "cure" autism by improving gut health through elimination of allergens from one’s diet. | While dietary interventions like gluten-free/casein-free diets have been shown to improve behavioral symptoms associated with Autism Spectrum Disorder (ASD), there isn’t enough scientific evidence yet available which supports claims that eliminating specific foods from one’s diet will completely eliminate autistic traits altogether. |
