While visiting my daughter at Thanksgiving time 2008, we noticed my then 7 year old grandson was making strange involuntary movements with his head. He would with some frequency jut his chin forward and upward, and then move it a little from side to side to stretch his neck. Again when we returned at Christmas time it was even worse, being more frequent when he was quiet than when active. It continued until summer of 2009 and suddenly by mid summer disappeared.
We noticed that the head movements began again by the end of October, 2009, this time with the addition of movements with his fingers like he was hand milking a cow. He complained of his fingers hurting from the movements which he could not stop.
My first thought was that there might be a seasonal factor or possible either the physical or emotional environment at school. One thing I thought about was the florescent lights in the school which are not full spectrum.
As an experiment in early November, 2009, we began giving him 2,000IU vitamin D3 capsules, three a day since he weighed about 80lbs. Our thinking was that maybe he was getting enough vitamin D from the sun in the summer, but not in the autumn and winter. An after some more research we added one 250mg Magnesium tablet per day beginning a few weeks later and a 5,000IU vitamin A capsule every other day.
So here we are 10 days into December, and for the last week we have not noticed any tics. I realize it is harder to observe something that isn't there than to notice something that is, so we are tentative in our certainty about this cure working, but excited nonetheless.
I will post again in two months, hopefully to confirm that this truly has worked. If anyone else is experiencing this problem, please post your results if you try the vitamin D3, Magnesium, Vitamin A treatment.
