Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Tics may increase as a result of stress, fatigue, boredom, or high-energy emotions, which can include negative emotions such as anxiety, as well as positive emotions such as excitement or anticipation and usually disappears while concentrating on other works. If you suspect that tics have started after the new born baby has come home may be this child, if feeling left out which results in emotional stress causing tics. In Tourette s they are frequently associated with learning disabilities, ADHD, compulsive behaviors and this disorder tend to be lifelong. But, it is better to do EEG (electroencephalography) to differentiate from myoclonic jerks which are associated by brief isolated jerks. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shivtej N
