Hello and welcome. Our son (15yo) is/was also a mild case. He had some eye blinking as a toddler but nothing consistent or alarming. Classic PANDAS appeared at around 6yo after a strep infection. We had tons of symptoms (tics, hyperactivity, encopresis, night terrors, insomnia, emotional lability, etc.) but overall still a bright, functional kid and no school disruption. He was positively diagnosed using the Cunningham panel, which also showed him on the mild end of the population. Other than some minor diet changes, we only treated with prophylactic antibiotics and occasional ibuprofen. Tics are one of his more lasting symptoms (infrequent now, but he still does flare a little). He did have some stomach issues that could have been from the antibiotic use, so we would sometimes take breaks and address his gut health. He is a happy high school student now, straight A's, no current PANDAS treatments other than probiotics. His tics don't seem to bother him at all when he flares now and they are much milder as well.
Steroids are the ‘big stick’ used to get brain inflammation down when ibuprofen is not effective.
