Summary

Patients with preoperative cognitive impairment are at increased risks of delayed neurocognitive recovery (DNR) and postoperative neurocognitive disorder (POCD). Repetitive transcranial magnetic stimulation (rTMS) has been used to improve cognitive function in patients with cognitive impairement. This trial is designed to compare the effects of rTMS versus sham intervention on postoperative neurocognitive function in patients with preoperative cognitive impairment.

  • Delayed Neurocognitive Recovery
  • Postoperative Neurocognitive Disorder

Interventions

DEVICE

Repetitive transcranial magnetic stimulation

Repeated transcranial magnetic stimulation (rTMS) over left dorsolateral prefrontal cortex (DLPFC) for a 5-day period (1 day before surgery and 4 consecutive days after surgery, twice daily \[10-12 am and 6-8 pm\], no intervention on the day of the surgery). Parameters of rTMS: "8" shaped coil, 10 Hz, 80% resting motor threshold (RMT), 2000 pulses (5s × 40 trains, 25 s interval), 20 minutes.

DEVICE

Sham stimulation

Sham repeated transcranial magnetic stimulation (rTMS) over left dorsolateral prefrontal cortex (DLPFC) for a 5-day period (1 day before surgery and 4 consecutive days after surgery, twice daily \[10-12 am and 6-8 pm\], no intervention on the day of the surgery). Parameters of rTMS: "8" shaped sham coil, 10 Hz, 80% resting motor threshold (RMT), 2000 pulses (5s × 40 trains, 25 s interval), 20 minutes.
