My son has tics, but does not have TS. His tics are not vocal ones, but tend to involve jerking movements in his face, shoulders, and most recently, his leg. He can control it for a period of time, but the resulting discomfort he feels usually leads to him giving in to the "urge." For him I think it is a comorbidity of the rest of his unique neurology, but I do not think it is a separate issue, nor do I believe it is TS.
The dx criteria for TS is (though it may have changed with new DSM?)
• both multiple motor tics and one or more vocal tics must be present at the same time, although not necessarily concurrently;
• the tics must occur many times a day (usually in bouts) nearly every day or intermittently over more than 1 year, during which time there must not have been a tic-free period of more than 3 consecutive months;
• the age at onset must be less than 18 years;
• the disturbance must not be due to the direct physiological effects of a substance (e.g. stimulants) or a general medical condition (e.g. Huntington's disease or postviral encephalitis).
Hope this helps!
