Ts and returning to school
Sept has always been a difficult my for our dd with TS, OCD and Sensory issues. The anxiety is the biggest contributor. Anxiety can certainly make the symptoms worse. If there is a component of OCD also, you may not know what disturbing thought are coming into your little darlings head (they cannot control the thoughts and may react to them with increased symptoms of tics or troubled behaviour). If your child with TS also has sensory issues, than part of the problem may be due to the weather and the fact that they have to wear more clothing and then they may be gettting into sensory-overload of their tactile system. Sweaters or coats, even carrying a backpack can add to their oversensitive tactile system because there is more "touch" to their body. Wearing long pants and sock and perhaps heavy shoes (as compared to what they were wearing all summer), and overload their brains and cause anxiety, which will make their TS flare up. There is the added noice of the classroom to combat their sensitive sensory processing that can be overwhelming also. So many factors that most of us just take for granted because our brain just filters out the extra stimulous - is you have TS with sensory problems, your brain has difficulty processing the information and filtering out the excess, causing symptoms to flare. They might be just more irritable, or extreme acting out in reaction and probably cannot even articulate what they are feeling.
There is a great book called The Out of Sinc Child that can explain this all in greater detail. An easy read that really helped my husband and I identify with our dd sensory problems and TS.
Hope this was helpful.
Being different is special.
