Area of Science:

  • Neuroscience
  • Biomedical Engineering

Background:

  • Bidirectional deep brain stimulation (DBS) devices record neural activity but face memory limitations requiring frequent data downloads.
  • Data loss is a significant concern due to memory constraints on implanted DBS devices.

Purpose of the Study:

  • To present a novel collaborative data collection method for DBS devices.
  • To reduce neural data loss by utilizing a nationwide network of device representatives.
  • To minimize patient travel burden associated with frequent data downloads.

Main Methods:

  • Collected chronic neural data from nine patients with severe obsessive-compulsive disorder (OCD) undergoing ventral capsule/ventral striatum (VC/VS) DBS.
  • Included patients with Medtronic Percept generators.
  • Coordinated data acquisition with patients and local device representatives for remote downloads.

Main Results:

  • Collected 40,080 hours of neural data, with 43.0% from representative-facilitated remote downloads.
  • Seven device representatives completed 21 downloads across seven cities.
  • Six out of nine patients completed at least one remote download.

Conclusions:

  • The data collection strategy effectively minimizes neural data loss for remote or infrequently visiting patients.
  • Challenges persist in ensuring regular downloads to prevent data loss.
  • Automated downloads could further reduce data loss and patient burden.
