Investigating dual-task biomarkers of subjective cognitive decline using functional near-infrared spectroscopy

Talia Salzman · Diana P. Tobón · Vanessa Taler · Sarah Fraser

Older adults with subjective cognitive decline (SCD) may be at a greater risk of cognitive impairment than older adults without SCD (i.e., non-SCD). This study examined dual-task changes in cerebral oxygenation and performance to determine whether these changes may be used as a biomarker in older adults with SCD. Older...
