 Surgery for movement disorders includes both DBS and procedures where part of the brain is frozen or cauterized. The latter procedures include thalamotomy for tremor and pallidotomy for Parkinson's disease and dystonia. These procedures were common before 1997, but have largely been discontinued. All of these procedures are carried out using similar techniques and therefore have similar complications. As seen in the chart below, hemorrhage, infection, and mechanical failure are the three most common complications. We list below the overall percentage of complications as sited in the literature and the percentage of complications experienced at Johns Hopkins. For each of aforementioned complications the percentage as quoted in the literature and as seen at our center are listed. All cases, including DBS and lesioning, are included with respect to the risks of bleeding and infection. Only cases of DBS are included for mechanical failure.  * REFERENCE ARTICLES Oh MY, Abosch A, Kim SH, Lang AE, Lozano AM. "Long-term hardware-related complications of deep brain stimulation."
