The purpose of this international study is to evaluate long-term safety and effectiveness of Abbott deep brain stimulation (DBS) systems for all indications, including Parkinson's disease, essential tremor or other disabling tremor and dystonia.
Subject is scheduled for a new implant or IPG device replacement surgery with a market-released Abbott DBS system within 180 days.
Subject, or a legally acceptable representative, must provide written informed consent prior to any study-related procedure.
Subject is currently enrolled or plans to enroll in an investigational study that may confound the results of this study.
Subject has anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the study or to comply with follow-up requirements, or impact the scientific soundness of the study results.
Study center is located in the United States, and indication for DBS implant is not Parkinson's disease or disabling tremor.
Study center is located in the United States, and the intended lead implant location is not at, or in close proximity to, the STN, GPi, or VIM thalamus.
This study will enroll male and female subjects diagnosed with Parkinson's disease, essential tremor or other disabling tremor, or dystonia who are scheduled for a new implant or IPG device replacement surgery with a market-released Abbott DBS system.

Deep Brain Stimulation (DBS)
DeviceDeep brain stimulation therapy involves the delivery of electrical signals to targeted structures in the brain to modulate neural circuit activity, and has been used successfully for the treatment of various types of movement disorders, including Parkinson's disease (PD), disabling or essential tremor, and dystonia
Change from baseline to 6 months in disease-specific motor rating scale. For subjects with Parkinson's disease, MDS-UPDRS Part III.
The Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) assess the severity of Parkinson's disease. This questionnaire is composed of four sections: Part I: non-motor experiences of daily living consisting of 13 questions (Part Ia is assessed by the investigator while part Ib is assessed by the subject, with or without the help of the caregiver); Part II: motor experiences of daily living consisting of 13 questions, designed to be self-administered; Part III: motor examinations consisting of 33 scores based on 18 questions with several right, left or other body distribution scores; Part IV: motor complications: consisting of 6 questions. Each item is scored from 0 to 4, where 0 indicates normal, 1 indicates slight symptoms, 2 indicates mild symptoms, 3 indicates moderate symptoms, and 4 indicates severe symptoms. The total score for each part is obtained from the sum of the corresponding item scores. Higher scores indicate greater impact of PD symptoms.
