ITA with everything in the above post. My 9 year old has gone through a series of tics-- mostly motor tics but some vocal when he was around 4-5 years old. At this point, and for the last two years, he has pretty much exhibited only an eye-blinking tic. If you's asked me when he was six, I would have been positive we were heading towards a Tourette's diagnosis-- now, I'm fairly certain we are not. My son also has a number of other related issues: generalized anxiety, OCD, and minor sensory stuff. And still, I think this is just an intermittent tic thing with him because it has gotten much less frequent and less varied over the years. I will watch your video later, but if it is a tic, I would assume it could easily pass, or come and go, and even if it shifts to a different type of tic (which my son experienced) it still may not be Tourette's. But yeah, a 504 could be helpful in school so that his tic(s) is acknowledged as such and does not get construed as a "behavior" issue.
