The characteristics of the tourette syndrome a neurological disorder

  • The following are the most common tic behaviors associated with TD;
  • It's a complex disorder likely caused by a combination of inherited genetic and environmental factors;
  • In other words, if a parent passes the gene on to a child, the child may not have any symptoms of the disorder.

Tourette's disorder TDsometimes called Tourette's syndrome TSis a neurological disorder characterized by multiple repeated tics. Tics are abrupt, purposeless, and involuntary vocal sounds or muscular jerks.

With time, tics may become more frequent and increase in variety, involving more body parts, such as the trunk or legs, and often become more disruptive to activities of daily living ADLs. What causes Tourette's disorder? Tourette's disorder is an autosomal dominant disorder.

Complications of pregnancy, low birth weight, head trauma, carbon monoxide poisoning, and encephalitis are thought to be associated with the onset of nongenetic TD.

Dominant disorders exhibit something known as incomplete penetrance, which means that not everyone with the gene will have symptoms of Tourette's disorder.

  • Conditions often associated with Tourette syndrome include;
  • Tic behaviors seen in TD change over time, and vary in frequency and complexity.

In other words, if a parent passes the gene on to a child, the child may not have any symptoms of the disorder. Finally, dominant disorders can also exhibit something known as variable expressivity. This means that there are differences in the expression of the TD gene in different people.

Tourette's Disorder

In addition, there are differences in expressivity between males and females: Who is affected by Tourette's disorder? A diagnosis of TD is generally made before the child reaches his or her 18th birthday.

In the majority of cases, a child is diagnosed around the age of 7. TD affects more males than females.

What are the symptoms of Tourette's disorder? Tic behaviors seen in TD change over time, and vary in frequency and complexity.

The following are the most common tic behaviors associated with TD. However, each child experiences symptoms differently. Involuntary, purposeless, motor movements may involve different parts of the body, such as the face, neck, shoulders, trunk, or hands:
