Behavior therapy effective in reducing tics

Courtesy of Science Daily: A study at UCLA finds that behavior therapy can be a very effective means of reducing tics in individuals with Tourette Syndrome. Basically, when the individual feels the premonitory urge to tic, s/he is taught to engage in an action that is incompatible with the tic (e.g., instead flinging your arms out behind you cross the in front of your chest).

Now, unfortunately my son tried this method, and we discovered that he is among the minority of individuals who actually will experience more severe tics after implementing this approach. This does not detract from my support of use of the method in general. I am fully in favor of finding non-invasive means of managing TS.
