About this trial

Declines in cognitive function and walking function are highly intertwined in older adults. A therapeutic approach that combines complex (cognitively engaging) aerobic walking exercise with non-invasive electrical brain stimulation may be effective at restoring lost function. This study tests whether electrical stimulation of prefrontal brain regions is more beneficial than sham stimulation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age 65+

Objective executive function decline, based on standardized cognitive assessments.

Subjective cognitive decline, based on the question: "During the past 12 months, have you experienced confusion or memory loss that is happening more often or getting worse?"

Ability to walking independently for 6 minutes (use of cane permitted)

Disqualifiers

Major cognitive disorder that interferes with independence

Percentile score less than 10th percentile on standardized cognitive assessments

Medications that are thought to influence tDCS neuroplasticity.

Contraindications to tDCS or MRI.
