Tourette's syndrome is a neurological illness, where certain brain cells repeatedly fire and fire again. When the brain cells fire, the symptom can be muscle twitches, shouts. This syndrome is mostly known for some people with it shouting obscene words, but all people with tourette's syndrom do not have this well-known symptom. People with this illness say that it feels as if a steam is building in their brain and has to be releasted by a muscle twitch. Then the steam is released, but soon starts building again.
Anti-psychotic medicines are sometimes used to treat this syndrome, but these medicines are not so effective and have difficult side effects.
The best treatment is brain surgery. A method originally developed for treating Parkinson's illness is used. Electrodes are inserted near the corrupt brain cells. These electrodes sends a current into the cells, which inhibits their actives and stops the action of these brain cells. This surgery can give enormous improvement, a patient who before had muscle twitches all the time becomes quite normal.
