- Presence of cognitive, or psychiatric or other co-morbidities (e.g., dementia, epilepsy, cranial traumatism, brain tumor, schizophrenia, severe depression or bipolar disorder, personality disorder, etc.) that might interfere with the patient's ability to complete the evaluations or to provide informed consent
- Other conditions considered by the investigators that might interfere with the surgery procedure, the follow-ups, and the interpretation of the data
Other
- Atypical parkinsonism
- Presence of anatomical abnormalities in the target region
- Clinically significant medical history that would increase pre-/post-operative complications
