Tourette syndrome, also referred to as Gilles de la Tourette syndrome, affects the brain, resulting in involuntary sounds and movements, or tics. The ]]>Centers for Disease Control and Prevention (CDC)]]> pointed out that in the United States, three out of 1,000 children between ages six and 17 have Tourette syndrome. Symptoms of Tourette syndrome tend to start between ages seven and ten, with the severity ranging from mild to severe. ]]>MedlinePlus, a service of the US National Library of Medicine and the National Institutes of Health]]>, notes that boys are four times more likely than girls to have Tourette syndrome.
The ]]>MayoClinic.com]]> explained that the tics from Tourette syndrome are classified into two groups: simple tics and complex tics. With a simple tic, the patient has a brief involuntary action that has minimum movement. In comparison, with a complex tic, the patient has involuntary movements that involve multiple muscles. Tourette syndrome patients can have motor tics and vocal tics, which can be simple or complex. For example, eye blinking is a simple motor tic and arm flapping is a complex motor tic. In addition, yelling is a simple vocal tic and using expletives is a complex vocal tic.
Doctors can prescribe medications for the treatment of Tourette syndrome. For example, dopamine blockers are used for tics. Examples of dopamine blockers include risperidone, fluphenazine, pimozide and haloperidol. These drugs work by reducing the amount of the neurotransmitter dopamine in the brain, which helps control the tics. However, these medications do have side effects, such as cognitive dulling and movement disorders, according to MedlinePlus.
]]>Reuters Health]]> reports that a type of behavior therapy, called comprehensive behavioral intervention for tics (CIBT), can treat the tics at a similar effectiveness as the medications, but without the side effects.
