Study Summary

This trial tests a non-invasive brain stimulation to improve memory recall and sleep in healthy elderly people. It involves lab visits and EEG collection at home.

Who is the study for?
This trial is for healthy elderly individuals over 50 years old who are interested in participating in a study to improve memory and sleep. Participants will undergo non-invasive brain stimulation and cognitive testing, with follow-up sessions to measure the effects.Check my eligibility
What is being tested?
The trial tests if gamma transcranial alternating current stimulation (tACS) can boost memory recall and affect sleep patterns in older adults. It compares gamma frequency tACS against a control frequency, using EEG headbands at home and actigraphy wristbands to monitor results.See study design
What are the potential side effects?
Transcranial alternating current stimulation may cause mild side effects such as tingling on the scalp, dizziness, or headaches during or after treatment. The intensity of these side effects varies from person to person.

Trial Design

2Treatment groups
Experimental Treatment
Group I: First gamma (40Hz) stimulation, then active control (21Hz) stimulationExperimental Treatment4 Interventions
After collecting sleep EEG at home for one night to acclimate to the data collection during sleep, participants first receive gamma (40Hz) tACS on Day 1 followed by a 5-9 day washout. Participants then receive active control (21Hz) stimulation.
Group II: First active control (21 Hz) stimulation, then gamma (40 Hz) stimulationExperimental Treatment4 Interventions
After collecting sleep EEG at home for one night to acclimate to the data collection during sleep, participants first receive active control (21Hz) tACS on Day 1 followed by a 5-9 day washout. Participants then receive gamma (40Hz) stimulation.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What objectives are this investigation attempting to achieve?

"The main objective of this trial is to ascertain the rate at which participants can successfully complete cognitive testing during transcranial alternating current stimulation (tACS). Secondary goals include assessing executive functioning with a Stroop Test and Trail Making Test, as well as measuring attentional performance via the Test of Attentional Performance (TAP). All assessments will be conducted both immediately following tACS as well as in the days that follow."
