A new study1 published in the Journal of Probiotics & Health suggests that probiotic (see Probiotics Learning Lab) supplementation may have a beneficial effect on digestive issues associated with Autism (see Probiotics Learning Lab for more glossary terms) Spectrum Disorder (ASD).
The study, carried out by Pure Research Products LLC, and led by John Sichel, involved 25 participants who were supplemented daily with a probiotic formula containing strains of L. acidophilus, L. casei, L. delbruecki, B. longum, and B. bifidum, for a period of 42 days.
Throughout the trial period the participants’ digestive symptoms and ATEC (autism treatment evaluation checklist) scores were tracked and measured by parents and caregivers. ATEC scores are used to evaluate autism severity through four categories: (1) speech/language/communication; (2) sociability; (3) sensory/cognitive awareness; and (4) health/physical/behaviour. These scores were taken before the trial commenced to achieve a baseline score, and then throughout the trial to track any changes.
The results revealed that the probiotic formula had a significant beneficial effect on digestive conditions, with participants showing a 48% improvement in diarrhoea and a 52% improvement in constipation. ATEC scores were also dramatically decreased, with participants showing an overall decrease of 88%.
"Lead researcher John Sichel, commented; “With autism rates rising dramatically in recent years, there is an ever-increasing need to identify remedies for common issues among children with ASD. Nutritional supplements may be well-positioned to help with the commonly reported gastrointestinal problems among children with ASD. According to the findings in this study, the probiotic formulation holds promise as a potential remedy for children with ASD and GI dysfunction or abnormal stool testing.”
