An Illinois mother has revealed the heartbreak of being one of the triggers for her daughter's tics from Tourette Syndrome - until a new therapy changed all that.
Avery, who asked that we not use her last name, was eight years old when she was diagnosed with Tourette Syndrome, a nervous system disorder that causes involuntary behavioral tics.
Soon her mother, D'Ann, became one of the triggers. The way she spoke or breathed could make Avery's entire body jerk.
It became so difficult that the two had trouble being in the same room together.
Then, a year ago, the family decided to try a relatively new form for therapy that teaches sufferers to recognize the tics and create a competing response to fight the urge to do it.
Now, the mother-daughter pair can not only just be in the same room together, but love shopping and dining together, and braiding each other's hair.

It is estimated that approximately 300,000 children in the US have the disorder, according to the Tourette Association of America.
The syndrome is often co-diagnosed with conditions such as Obsessive Compulsive Disorder, which Avery also has.
Avery had 26 tics including shrugging her shoulders, turning her wrists, blinking several times and tensing her body.
Around age 10 or 11, she began mimicking her mother, and that became one of her tics.
'When I asked my mom a question, she had to answer: "Yes", it couldn't be: "Sure,"'Avery explained to DailyMail.com.
'When it wasn't that, that would upset me and I would tic.'
