Are there associated disorders?

Many with TS experience additional neurobehavioral problems including inattention; hyperactivity and impulsiveness or acting before thinking, (attention deficit hyperactivity disorder—ADHD); obsessive-compulsive symptoms such as intrusive thoughts/worries and repetitive behaviors; learning disabilities that may include reading and writing difficulties, problems with mathematics and perceptual problems.

People with TS have also reported problems with depression or anxiety disorders, as well as other difficulties with living, that may or may not be directly related to TS. Sleep Disorders are fairly common among people with TS. These include difficulty getting to sleep, frequent awakenings or walking or talking in one's sleep.Compulsions and Ritualistic Behaviors may also occur. This is when a person feels that something must be done over and over and/or in a certain way. Examples include touching an object with one hand after touching it with the other hand to "even things up" or repeatedly checking to see that the flame on the stove is turned off. Children sometimes beg their parents to repeat a sentence many times until it "sounds right." Repetitive copying and erasing of work in school can be quite disabling. Given the range of potential complications, people with TS are best served by receiving medical care that provides a comprehensive treatment plan.
