2018 AANS Annual Scientific Meeting-New Targets for DBS for Movement Disorders

Video Transcription

Video Summary

In this video, Patrick Blomstedt from Sweden discusses new targets for deep brain stimulation (DBS) in movement disorders. He mentions that there are a few newly created targets, such as the nucleus basalis of Maynard and the peduncle pontine nucleus (PPN). However, in his personal experience, these targets have not shown significant cognitive or motor improvements and are not commonly used. He also talks about resurrected targets from the lesional era, such as the globus pallidus internus (GPI) and the substantia nigra, which have been found to have some positive effects on freezing of gait. Blomstedt focuses on the posterior subthalamic area (PSA) as a target for DBS in essential tremor and mentions its advantages over traditional targets like the ventral intermediate nucleus (VIM). He shares his personal experience with PSA DBS and states that it has shown better efficacy and long-term outcomes. Blomstedt also discusses the use of directional leads for stimulation in the PSA, which has shown promising results in terms of reducing side effects and improving effectiveness. Overall, he concludes that the PSA is a better alternative to the VIM for treating tremor in essential tremor patients.
