Summary

Delayed neurocognitive recovery is a common neurocognitive complication in older patients after surgery, especially those with preoperative neurocognitive decline. Transcranial photobiomodulation therapy is a novel neuromodulation technique using transcranial low-power light to modulate brain biological functions. This technique has been used to treat various neurological or psychiatric conditions, including ischemic stroke, traumatic brain injury, and major depression. This study is designed to explore whether using transcranial photobiomodulation therapy during the perioperative period can reduce the incidence of delayed neurocognitive recovery in older patients with pre-existing neurocognitive impairment.

Conditions

  • Older Adults
  • Surgery
  • Transcranial Photobiomodulation
  • Delayed Neurocognitive Recovery
  • Postoperative Delirium

Interventions

DEVICE

Transcranial photobiomodulation therapy

A transcranial photobiomodulation therapy device employing medium-intensity LED near-infrared light will be applied to the foreheads of participants. Treatments will be done twice daily on the day before surgery and on the first and second days after surgery, and once on the day of surgery, with at least 8 hours between any two treatments. Each intervention will last 10 minutes. The investigators conducting the bedside intervention will monitor the safety of participants during the interventions.

DEVICE

Transcranial pseudo-photobiomodulation

A transcranial photobiomodulation therapy device employing extremely low-intensity LED near-infrared light will be applied to the foreheads of participants. Treatments will be done twice daily on the day before surgery and on the first and second days after surgery, and once on the day of surgery, with at least 8 hours between any two treatments. Each intervention will last 10 minutes. The investigators conducting the bedside intervention will monitor the safety of participants during the interventions.
