What Are The Symptoms Of Tourette Syndrome?

I m pretty sure my spouse has Tourette s. He clears his throat repeatedly, sniffles, & probably the thing that drives me crazy the most is he slaps his leg/thighs frequently & if he s not doing that he is tapping the table with his fingers. He also has an explosive temper & his eruptions are based on usually something so insignificant that the average person would not enter into an argument about it. At these times he is verbally abusive! These eruptions occur weekly. Any suggestions as to how I can help him with this condition. He has not been diagnosed with this & I m certain he will not discuss this with his Dr. I also consider him to be ADHD although he s Beverly discussed this with the Dr either.
