Postmortem observation of collagenous lead tip region fibrosis as a rare complication of DBS.
TL;DR: Despite the widespread effective use of deep brain stimulation for various movement and psychiatric disorders, little is known about its safety and tissue responses.

TL;DR: There was reported transient benefit in levodopa responsive features that indicate deep brain stimulation may be an option for select multiple system atrophy patients, and further investigation is necessary.

A pilot study of human brain tissue post-magnetic resonance imaging: information from the National Deep Brain Stimulation Brain Tissue Network (DBS-BTN).

TL;DR: No clinical signs or symptoms or MRI-induced adverse effects were discovered in the DBS-BTN database, and the lack of tissue related changes following prolonged exposure to 3T MRI in the post-mortem brains suggest that MRI scanning in DBS patients may be relatively safe, especially under current guidelines requiring a head receive coil.

The national DBS brain tissue network pilot study: need for more tissue and more standardization
Vinata Vedam-Mai,Nolie E. Krock,Michael Ullman,Kelly D. Foote,W. Shain,K. Smith,Anthony T. Yachnis,Dennis A. Steindler,Brent A. Reynolds,Stacy Merritt,Fernando Pagan,J. Marjama-Lyons,P. Hogarth,Andrew S. Resnick,Pamela Zeilman,Michael S. Okun +15 more
TL;DR: Preliminary results demonstrated the feasibility and utility of creating a National DBS-BTN resource for the scientific community, and plans to improve the techniques to remedy omitted clinical/research data, and expand the Network to include a larger donor pool.
