One line that stuck out to me regarding the outcomes of the fecal transplants was ‘improved gastrointestinal symptoms’. If people with ASD have higher rates of GI-related issues, then the findings of this paper could be really helpful in understanding and improving treatments for GI problems in patients with ASD. Of course I understand the skepticism that this work could be used to try and cure something that doesn’t need to be cured, but my hope is that the more likely outcome is a more holistic understanding of ASD that leads to better medical care across all areas of health.
