This study is looking at how a history of mild traumatic brain injury (mTBI), like a concussion, might be connected to amnestic mild cognitive impairment (aMCI), a type of memory problem. Researchers will use a device called High Definition Transcranial Direct Current Stimulation (HD-tDCS) to understand brain activity. This device delivers a very mild electrical current to the brain. You may be able to join if you are 55 or older, have been diagnosed with aMCI, and speak English fluently. The study will measure changes in your memory using a test called the Rey Auditory Verbal Learning Test Score. The current recruitment status is unclear.

Study design

This is an interventional study planning to enroll 75 participants. It involves different conditions of HD-tDCS, including active stimulation and a sham (inactive) condition.

What's involved

You will have 10 study visits. This includes a blood draw, memory evaluations, and three consecutive daily sessions of HD-tDCS for each of the three conditions, separated by 14 days.

Compensation

Not stated in the trial record.

Follow-up

Memory assessments are completed immediately after each HD-tDCS condition.
