30th March 2008 - New research ADVERSE EVENTS AFTER DBS SURGERY Movement Disorders [2008] 23 : 343-349 (A Videnovic, L Verhagen Metman) Complete abstract DBS is a surgical method of treating Parkinson's Disease that uses electrodes implanted into the brain. For more information go to Deep Brain Stimulation. Traditionally, the two most common sites in the brain used in surgery are the subthalamic nucleus (STN) and the globus pallidus interna (GPi). The authors analysed reports of adverse events from over a thousand patients who had undergone DBS surgery. The most common adverse events were, in order : weight gain, then confusion, then speech difficulties. Neither part of the brain that was used had clearly fewer adverse events than the other. Adverse events related to DBS surgery are common, but the study authors concluded that their true prevalence cannot be accurately determined with current reporting methods. For more information go to the Complete article The most common adverse events were :
Stimulation or progression related events (% of STN / % of GPi) : Weight gain 37% / 18%, Dysarthria (speech disorder) 13% / 12%, Eye opening apraxia 11% / 0%, Gait ignition failure 0% / 17%. Hardware-related events (Combined % of STN and GPi) : One or more events 9%, Infection 2%, Malfunctioning 1%, Lack of benefit 1%.
