Is there a scale for measuring the serverity of TS in a person?
 

While I have had TS my whole life, but had not known it until I was 31(I'm 48 now), I have often wondered if there was an actual scale of not the severity of a tic or tics, but on a scale of one to ten, how severe is ones TS? Personally speaking, since my diagnosis, I had been a 7 at one time years ago, but have mostly been about a 3. With the new tics that I have recently developed, and the usual tics, I am a 5. I am a public servant. A custodian. I often see others looking at me when I tic. Though the other custodians know and respect me. I am always ready to answer and educate anyone who would happen to ask why I do some of the quirky things that I do.

I'm not sure I understand your question.
Tourette's Syndrome = Tics.

Do you mean how they impact quality of life in individuals?

The Yale Global Tic Severity Scale (YGTSS) is a clinician-rated scale that rates tic severity in tic disorders. It was originally developed by Leckman and others for use in studies.

Comorbid conditions have been found to affect quality of life in people who have Tourette's Syndrome.

Some people who have what they may call 'severe' tics actually can have a great quality of life, whereas others with 'mild' tics may find it more difficult. There are so many different factors that it would be very difficult to actually measure. Some people have a greater ability to deal with them and some don't. Some tics are painful. Some tics affect a person's ability to work. The list goes on. It's such an individual experience and no two people are the same.

A couple of examples very quickly below (there are many and they are varied) regarding how comorbid conditions can affect quality of life ( QOL ) . They just show how complex it can be to measure.
