Descrizione dettagliata
This study is aimed at adults who have severe Tourette syndrome and who have found that conventional treatments, such as drugs, do not control their symptoms sufficiently or cannot be tolerated.
The first two clinic visits will involve assessments. Participants will fill in a number of questionnaires and be examined by a psychiatrist and a neurologist. At the second visit, the patient will provide consent for participation and will undergo formal tests to find out if the participant is suitable and willing to undergo the research study and to record the type and severity of their Tourette syndrome symptoms.
The third visit will be an admission to hospital to have the deep brain stimulation (DBS) devices implanted. The admission to hospital should be around five days in duration.
At the first post operative follow-up visit, the patient will be placed into a "stimulator on" group or a "stimulator off" group. To try and make sure that these groups are the same to start with, each patient is put into a group by chance (randomly). This visit will take place around six weeks after surgery. In this trial, the participant will have an equal chance of being in the "on" or the "off" group first. This trial is also a "blinded" trial, neither the patient nor the researchers performing the assessments will know which group the patient is in.
At the next visit, 3 months later, the patient will have a further assessment. If their stimulators have been "on" for the first 3 months, they will be switched off. If they have been "off" they will be switched on.
At the next visit, 3 months later, the patient will be assessed again and then given the opportunity to carry on the trial with the stimulators switched on for long term follow up.

Descrizione
Inclusion Criteria:
- The participant must be adult with stable Tourette syndrome.
- The participant must have a chronic and severe tic disorder with severe functional impairment, with a Yale Tourette Severity Scale score of at least 35/55 for at least 12 months prior to surgery.
- The participant must have failed conventional medical treatment at therapeutic doses of three classes of medication.
- The participant must not be suitable for behavioural intervention or that this intervention is inappropriate or unsuccessful.
- The participant must have been on stable and optimised treatment of co-morbid conditions for at least 6 months.
- The participant must be actively involved with and compliant with any psychosocial interventions.
- The patient must be compliant with treatment plans.
Exclusion Criteria:
- The tic disorder is attributable to any other condition.
- Any other medical or psychiatric disorders that substantially increase the risk of a failed procedure or that would significantly impede recovery.
- Psychosocial factors which might impede operative and post-operative care and research participation.
- Coagulation problems
- Other disease compromising life expectancy
- Patient likely to benefit from psychological intervention
- Patient unwilling to co-operate with post operative assessment and care
- Pregnancy.
- Participant under 20 years old.
