My son is 26, has no speech or much understanding of speech..severe 'autism' since 18 months... Began having very severe, sometimes very alarming tics and life controlling OCD in his teens. Before that he was making slow, steady progress. All progress stopped when the tics began 10-15 years ago. He has had many different extreme tics through the years, currently constant spitting, extreme OCD, impulsivity and prompt dependence. I have just learned of a plant that apparently is helping many tic sufferers... Look up 'Joyle' , who is a member of this group. I Also just joined the fb group she recommends, Natural care for tics and Tourette's. Pharmaceuticals have only worsened my sons condition... Also dental procedures seemed to have aggravated ...
