The lead in the study was Dr Dorothy Gronwall in New Zealand. She repeated some of the study in the 90's. A past NT member was one of her patients shortly before Dr Gronwall's passing in 2001.

Go ahead and doubt her research. If the power of positive thinking about a 100% recovery helps you do better, then go for it.

I have had many 100% recoveries from concussion symptoms. But, I still had to deal with relapses due to stress and an increased sensitivity to head movements.

It was a very minor head jerk on January 16, 2001 that put me over the edge.
