The inheritance pattern of Tourette syndrome is unclear. Although the features of this condition can cluster in families, many genetic and environmental factors are likely to be involved. Among family members of an affected person, it is difficult to predict who else may be at risk of developing the condition.
Can Tourettes skip a generation?
Tourettes is a neuropsychiatric disorder that appears to be inherited. However, it skips generations with the result that is does not come directly through the parents. The gene that causes this disorder has not yet been identified.
Do tic disorders run in families?
While tic disorders are thought to be strongly familial and heritable, precise estimates of familial risk and heritability are lacking, although gene-searching efforts are under way.
Can you get Tourettes on purpose?
Having a tic is hard to control. The motor and vocal tics of Tourette are involuntary, meaning that people do not do the tic on purpose. While the exact cause of tics is still not known, many people compare the feeling of having a tic to having an itch or having to sneeze.
Does Tourettes improve with age?
Tourettes syndrome is a condition that causes a person to make involuntary sounds and movements called tics. It usually starts during childhood, but the tics and other symptoms usually improve after several years and sometimes go away completely.
