Helminthic therapy and autism
Autism subtypes[edit | edit source]
Italian researchers have suggested that there may be two subtypes of autism, inflammatory ASD (I-ASD) and non-inflammatory-ASD (NI-ASD).
Those subjects with inflammatory ASD are likely to exhibit chronic and/or recurrent sino-pulmonary infection, asthma and persistent GI symptoms with high frequency non-IgE mediated food allergy. Those with this subtype are more likely to have a better response to antinflammatory therapies such as helminthic therapy than are those with non-inflammatory ASD
Significant results have been observed over a 4-5 year period in 70% of those with inflammatory ASD who took TSO in its original pH2.7 form, and the improvements observed were not only in the quality of stool and control of allergic symptoms, but also in improved behaviour and cognitive skills.
For more detail about this, see this post and this support group thread.

Anecdotal reports about under 18s with autism (ASD)[edit | edit source]
Three comments by a parent/therapist
TSO and HDC have both been found generally effective in autism, and NA may help with some of its co-morbidities, but individuals can respond uniquely to the different helminths.
When using helminths in children with autism, they should be introduced VERY gradually to avoid triggering severe side effects.
Once smaller doses of TSO have been tolerated, 2,500 ova has been found to be best dose size in most cases.
Further collection of reports:
Also see Table 2 in this paper.
- The following five reports, written over a period of 6 years, all relate to the same child.
- "Since then Alex has made nothing short of stunning progress. I mean WOW." (Link expired)
- "... there's no question that he and the other children who received hookworm all improved cognitively and in motor skills... Most of the younger children, the less impaired, also improved, sometimes dramatically, in expressive language" (Link expired)
- "My older son is 16 and autistic. I started with TSO 3 years ago and within 12 weeks or so, began to see positive results in terms of digestive symptoms, mood, and eventually cognition." (Link expired)
- “… I officially declare hookworms to be rockin’... this experiment has been a success ... But, if you’ll forgive the phrase, I have a gut feeling that we’re only seeing the tip of the iceberg so far.” (Posted on a since deleted website.)
- “We started the HDC in August (and) I have gotten similar results with the HDC as the TSO: he has no GI symptoms now and, except for a migraine condition that I am still working on, is almost continually very happy and social. I am going to be experimenting with much higher doses of HDC to see if we can improve the migraines more.” [9]
- The following two reports are about the same teenager.
- “There’re no words to describe it. It’s like giving me my son back... Or in many ways, like giving me a son that I didn’t ever have.” [10]
- “...we began treating my son with TSO. After 10 weeks he completely lost all symptoms of agitation, agression, self abusive behavior (including head smashing and hand biting), perseveration, behavioral inflexibility, compulsivity, impulsivity, repeated questioning, “stimming” and hypersensitivity to external stimuli. He continues to take TSO every two weeks and the symptoms have been gone now for 15 months. [11] and watch video
- "The teachers were telling us it was a definite possibility that he would never actually be able to write and that he would need assistive technology for life… We've been struggling to teach him to read for two years now… Well, in the last month (following inoculation), he's had major developmental leaps... and is now actually reading, has progressed about 12 months in the last month as far as his fine motor skills go. He's reading and writing now, actually reading at or above grade level." (Reported in a private discussion, 2011)
- "(Our son) has started playing imaginatively with toys for the first time in his life. He has started pretend playing appropriately with all kinds of different toys - cars, superhero action figures, dinosaurs, .... It's something we tried working on with him for years in his behavioral therapy and eventually gave up. I can't say for sure it's because of the helminths, but I can't think of any other reason for the sudden change. It's such a great feeling to see him doing this finally." (Reported in a private message, Nov 2012)
- The following three reports are by the same very happy parent.
- “... had to share this as its independent confirmation of what we've been seeing at home. Today I had a meeting at school to discuss my 6yo's special needs educational plan and was overjoyed when I was told without any prompting he had "a complete turnaround a few months ago after parents evening" and that he has been paying attention, sitting still and being kind to the other children. Guess what therapy we started in the week following that parents evening.” (Link expired)
- “For us, the benefits of giving my autistic 6yo HDC include vastly reduced risk to everyday dangers. I used to have to physically restrain him near roads as he had little control over impulses. We had more than one near miss when he bolted away into the path of unsuspecting cars! He now has sufficient control over impulses that he would not do that.” [12]
- “He's 7 now and continues to do really well, much calmer than he used to be. I'm so very proud of him today because he willingly went to an all-day holiday science camp in an unfamiliar location and where he knew nobody and he bounced out like any neurotypical kid and asked to go again.” [13], [14] and [15].
- “I am now pretty confident that TSO are a big success for my autistic boy (5 yo). The change has been amazing. He has a very long way to go, but the effect of TSO is very noticeable - for us, his therapists, his preschool. After years of really hard work and nothing helping, this is almost like magic... He is finally developing socially… We are so glad we plucked up the courage to try helminths.” (Link expired)
- ☹️ “First I tried TSO with my autism children and then I tried HDC. Was 8 months in total but I didn't see any results.” [16]
- “I wanted to report my experience so far giving my 15 year old son with significant autism TSO. I just gave him the second dose. From what I read it is supposed to be too soon to see results, but all I can say is WOW! We live in Austin and this is high allergy season. In addition to being on a year round allergy protocol (pills, sprays, naturals, etc), we had to give him headache medicine round the clock for allergy-induced migraines. He has had nothing for two weeks and is the happiest I have seen him in a long time. He has more energy, is more willing to try new foods and experiences, and just plain feels good. I am amazed because we have tried so many things to get his inflammation down and this is the one thing that has made a huge difference. I’m really excited to see what other changes we might see, but if this is it, it will have been worth it.” [17]
- "We use it with our 12yr old pandas, ASD, adhd & itch, and it has been a game changer for us! We are at 9 months & we started low & slow then worked our way up. We still have a long journey ahead of us, however this was one of the best interventions we have done so far." [18]

The role of the microbiota in autism[edit | edit source]
Worms and bacteria are known to interact in complex and subtle ways to provide an efficient and beneficial ecosystem.

The role of gut bacteria in autism is therefore arguably as important as that of helminths, and the two are likely to be complementary in addressing this disorder.

In view of the articles above, Fecal Microbiota Transplantation (FMT) might be worth considering for autism, either alone or in combination with helminthic therapy. For more about combining these treatments, see the following page.
Asperger (Asperger’s) syndrome[edit | edit source]
The limited feedback received so far from those with Asperger’s who are hosting helminths suggests that, while this therapy may not change the unique features of Asperger’s, it may make positive changes to health that can improve the life of someone with this form of autism.
