No severe complications were reported. It works particularly well for eye blinking tics, nose tics and neck and head jerking type tics. Doctors say side effects occur only if too much botox is injected and the muscle becomes too weak. Eighty-four percent of the patients with premonitory sensations reported significant relief of their symptoms. Also some patients reported their quality of life significantly improved with the treatment since it provided the relief for both the tics and the sensations.
Researchers say the botox inhibits the nerve from communication with the muscle.
The relaxing of the muscles helps alleviate the tics. Researchers conclude that botox injections are a safe and effective treatment for tics in patients suffering from Tourette syndrome. For some patients, the botox injections prevent the tics from returning for years. Doctors say this happens because tics come and go on their own and the injection might have been used during the time that the tic was about to stop. However, doctors say other patients need the injections about every four months.
