Original lecture slide 26, Directional DBS, comparing a ring contact producing a symmetrical field with a segmented contact producing a steered field

DIRECTIONAL DBS

  • Shape the field—don't just increase the dose
  • ELECTRIC FIELD
  • OMNIDIRECTIONAL → DIRECTIONAL
  • RING
  • SEGMENTED
  • WHY IT MATTERS
  • Steer current away from structures producing side effects and toward the intended therapeutic pathway.
  • Evidence: recent meta-analysis found a wider therapeutic window with directional DBS in PD, but benefit depends on lead location and programming.
