Full study title: Bright Spark: Measuring Brain Activity to Predict Cognitive Health in MCI & Alzheimer’s Disease


What is the study about?

This study looks at how the brain’s electrical signals can be used to improve the early detection of Alzheimer’s disease. Early detection of brain changes is crucial to prevent cognitive decline and dementia. This study uses electroencephalography (EEG) to record the brain’s electrical signals during simple tasks, with the hope of validating a measure that can improve early detection of Alzheimer’s disease.


Eligibility – Who can participate?

Participants must:

  • Be between 60 and 85 years of age
  • Have a diagnosis of Mild Cognitive Impairment or a diagnosis of Alzheimer’s dementia
  • Have normal vision (with visual aids, if needed) and no serious health issues

This study also requires participants to have a study partner who has known them for the last five years.


Time requirement

  • Visit 1: Lasting 2.5-3 hours, includes questionnaires about medical history, activities of daily living, an EEG test, and cognition, memory and thinking tasks.
  • Visit 2: A 1-1.5 hour visit with an EEG test only, 1-2 weeks after Visit 1.
  • Participants with a diagnosis of MCI will be asked to return for follow-up visits at 6, 12, and 18 months to repeat the same assessments as Visit 1.
