More often than not, Tourette's is a hereditary disorder. It passes through a gene carried in a family member and if carried by one the possibility of having it is 50%. It is more prevalent in males.
Medicines given to suppress tics are most often used to treat other neurological disorders simultaneously, such as Depakote, which suppresses seizures. People with Tourette's should avoid stressful situations and people that would upset them. Therapies such as anger management and emotional stability are very helpful in regards to tics and other agitations.
