The gender of the person also plays an important role in TS gene expression. At-risk males are more likely to have tics and at-risk females are more likely to have obsessive-compulsive symptoms.

Genetic counseling of individuals with TS should include a full review of all potentially hereditary conditions in the family. Genetic studies. Currently, NIH-funded investigators are conducting a variety of large-scale genetic studies involving TS. Understanding the genetics of TS genes may strengthen clinical diagnosis, improve genetic counseling, lead toward a better understanding of its causes, and provide clues for more effective therapies. NINDS-funded research is testing the effectiveness and safety of deep-brain stimulation DBS for treating tics and co-occurring conditions, such as obsessive-compulsive behaviors, in individuals with TS who do not respond well to medications and behavioral therapy.

DBS uses a surgically implanted, battery-operated medical device called an implantable pulse generator IPG —similar to a heart pacemaker and approximately the size of a stopwatch—to deliver electrical stimulation to specific areas in the brain that control movement, which blocks the abnormal nerve signals that cause symptoms.

Neuroimaging studies. Advances in imaging technology and an increase in trained investigators have led to an increasing use of novel and powerful techniques to identify brain regions, circuitry, and neurochemical factors important in TS and related conditions, such as ADHD and OCD.

Neuropathology the study of nervous system diseases. There has been an increase in the number and quality of donated brains from TS patients available for research purposes. This increase, coupled with advances in neuropathological techniques, has led to initial findings with implications for neuroimaging studies and animal models of TS.

Clinical trials. Several clinical trials in TS recently have been completed or currently are underway. These include studies of stimulant treatment of ADHD in TS and behavioral treatments for reducing tic severity in children and adults.

Smaller trials of novel approaches to treatment such as dopamine agonists and glutamatergic medications also show promise. Neurostimulation treatments such as DBS and noninvasive transcranial magnetic stimulation in children and adults are also ongoing. Epidemiology and clinical science. Careful epidemiological studies those that track the pattern or incidence of a disease now estimate the prevalence of TS to be substantially higher than previously thought, with a wider range of clinical severity.

Furthermore, clinical studies are providing new findings regarding TS and co-existing conditions. One of the most important and controversial areas of TS science involves the relationship between TS and autoimmune brain injury associated with group A beta-hemolytic streptococcal infections or other infectious processes. There are many epidemiological and clinical investigations currently underway in this area.

Consider joining a clinical study. Both healthy individuals and those with a disease or condition can participate in medical research studies sometimes called clinical trials or protocols to help researchers better understand a disease and perhaps develop new treatments. The findings have not only provided the basis for future experiments, but they also pave the way for novel therapies. As Caligiore and colleagues explain:. These predictions could be important for identifying new target areas, aside [from] the traditional ones to design innovative system-level therapeutic actions.

Learn how brain chemical may help to treat tics in people with Tourette syndrome. A study finds a link between fish intake and lower levels of markers for vascular brain damage in healthy older adults, especially those under 75…. A recent study suggests that low-frequency magnetic stimulation of a particular part of the brain could enhance the formation of memories. A new study challenges the belief that all cognitive functions worsen with age. The authors found that that orienting and executive functions improved.

To have Tourette means that a person has at least two different motor tics and at least one vocal tic, and has had tics for over a year. 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. You may try to stop the feeling, but eventually you will probably scratch or sneeze and you will feel a little better until the urge comes back. When people try to hold back their tics, it can cause stress and the tic may become worse.

It is true that some people with Tourette have difficulties throughout their lives. It is also true that many people with Tourette are very successful. They are often high achievers and find that their tics can become less severe or go away when they are concentrating on a task at hand. Many people also have fewer tics as they grow up.
