Who this trial is looking for
This trial is looking for people between 50 and 80 years old who have mild cognitive problems likely due to Alzheimer’s disease. Participants will take tests and may receive a non-invasive therapy while researchers study its effects.
Are You a Good Fit for This Trial?
You may be able to join if
I have mild cognitive impairment likely due to Alzheimer's disease.
I am between 50 and 80 years old.
I am a native English speaker.
You may not be able to join if
I have a brain tumor or other structural brain lesion.
I have an ongoing serious medical condition like cancer or heart disease.
I have a history of alcohol or substance abuse for over 10 years.
I have conditions that would make transcranial stimulation unsafe for me.

The project is a placebo-controlled study that aims to use closed-loop transcranial alternating current stimulation (tACS) to study patients with symptoms of mild cognitive impairment which is likely due to Alzheimer's disease or another form of dementia (AD-MCI). Patients will undergo an EEG and complete some questionnaires and computer tasks during each study visit. The project has the following aims and hypotheses: 1.) To determine the impact of closed-loop 40 Hz tACS on the entrainment of natural gamma rhythms in patients with AD-MCI, 2.) To determine the impact of closed-loop 40 Hz tACS on cognitive performance in patients with AD-MCI, and 3.) To assess the relationship between baseline neurodegenerative burden and impact of tACS. \[exploratory\]
