My child has been on the protocol for about 18 months, and repetitive behavior and speech seems to be an area that’s hard to improve. Any insight into this?

If you are seeing improvement with the protocol except for a few areas, further inflammation reduction is required by adding vagus nerve stimulation (VNS) for five min. once daily. Alternatively, increasing inulin to monthly rifaximin or monthly rifaximin to continuous rifaximin might also help. And finally, if continuous rifaximin and VNS are already being used, adding 1/4 tsp of inulin once daily to the rifaximin might help.
