Information About Tourette Syndrome
Tourette syndrome is a neurological disorder that results in repetitive involuntary movements and vocalizations called tics. It occurs in people from all ethnic groups and in both males and females, but males are typically affected three to four times more than females. The causes of Tourette syndrome are unknown, but it is believed that the condition may be hereditary.
Specific examples of common tics seen with Tourette syndrome include:
- Eye blinking and other vision irregularities
- Repetitive throat clearing
- Grunting sounds.
In almost all cases, early symptoms are first noticed in childhood; 7 to 10 years old is the average age of onset.
Although some studies suggest that this condition is inherited, scientists are unable to say which specific chromosomes and genes are involved. Most people with Tourette syndrome do not require medication, but drugs are available to help relieve behavioral symptoms that may occur in a person with this disorder, such as anxiety.
