- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Mental competence\*~* A current or previous psychiatric illness that has been stable for at least the last six months, meaning no overt psychiatric symptoms or decompensation based on a written report of the clinician that is treating the patient~* Diagnosis of TDD, TDD symptoms developed whilst being treated with dopamine blocking agents or within three months (for oral) or within six months (for depot) after withdrawal (definition international review of neurobiology 98)(6)~* TDD must be present for at least 12 months and impede with physical and or social functioning. In this study that is defined as a score of at least 4 on the disability rating scale of the BFMDRS with at least two items scoring a minimum of two, or one item scoring a 3 or higher.~* BFMDRS \>12 at the moment of evaluation~* The patient has proven treatment refractory for all other evidence based TDD treatments:~  * Withdrawal of the dopamine blocking agents or a switch to clozapine and/or quetiapine for at least 3 months~ * Adding tetrabenazine at the maximum tolerated dosage for at least 4 weeks~ * In focal dystonia a trial with Botulinum toxin (at least three sessions)~* The patient fully understands that DBS is not a treatment for the psychiatric disorder and agrees to take his or her psychiatric medication as prescribed by their psychiatrist.~Exclusion Criteria:~* The patient has unrealistic expectations of the possible benefit of DBS or does not fully understand the possible side effects and the likelihood of their occurring.~* The patient is suicidal, a score of ≥4 on item 19 on the BPRS~* Mattis scale for dementia \<120~* A score of ≥6 on the Clinical Global Impression scale (CGI) psychiatric severity scale or a BPRS ≥68~* A neurological disease that is the cause of the dyskinesia and/or dystonia~* Use of recreational drugs, such cocaine amphetamine or other drugs that affect TDD, within the last 3 months. Cannabis use within the last 3 months is not considered an exclusion criteria~* Previous DBS or ablative stereotactic brain surgery~* General contraindications for stereotactic surgery and general anaesthesia (e.g. severe hypertension, blood coagulation disorder)~* A seizure disorder that is not sufficiently controlled~* An implanted electronic device~* A language barrier that prevents the patients from understanding the investigators or vice versa

Study Arms:
- Immediate stimulation (Type: ACTIVE_COMPARATOR): Patients will be implanted with a Medtronic electorde and Active PC pulse generator for deep brain stimulation at baseline and GPi electric stimulation will start immediately after surgery
- Delayed stimulation (Type: SHAM_COMPARATOR): Patients will be implanted with a Medtronic electorde and Active PC pulse generator for deep brain stimulation at baseline and GPi electric stimulation will start 3 months after surgery

Based on this trial design, predict the completion outcome and termination type (if applicable).
