Intuition is a virtual, observational study using an Apple Watch and iPhone to study both memory and thinking, and longer-term changes in brain health.
The total duration of participation is 2 years. Participants will complete assessments throughout the study in the Intuition app and on a computer or iPad. Each assessment will take between 2 and 30 minutes, for a total of just over 1 hour per month on average over the 2-year study. The study will use data from normal everyday use of an Apple Watch and iPhone in combination with a health and habits survey every 3 months and validated cognitive test batteries. The study aims to identify digital biomarkers to help measure changes in thinking and memory in adults, as well as identify longer-term changes in brain health. Some changes in brain health may occur normally as we age, while others could be an early indicator of certain forms of dementia, such as Alzheimer’s disease. This study, therefore, may be an important step toward better understanding overall brain health.
Participants will be placed into 1 of the following cohorts depending on their responses to the prescreening questionnaire in the app:
Ages 50 to 86 years with a pre-existing diagnosis of MCI
Ages 50 to 86 years who report subjective cognitive complaints but do not have a pre-existing MCI diagnosis
Ages 21 to 59 years without a pre-existing MCI diagnosis
Ages 60 to 86 years with a limited number of self-reported risk factors for cognitive decline
Ages 60 to 86 years with at least 2 self-reported risk factors for cognitive decline
In addition, we will be recruiting participants from a select number of dementia research centers into the following cohorts:
Ages 50 to 86 years with a diagnosis of MCI based on established research criteria (e.g., National Institute on Aging Alzheimer’s Association [NIA-AA] diagnostic criteria for MCI)
Ages 50 to 86 years without evidence of cognitive impairment
Ages 50 to 86 years without an MCI diagnosis but positive for an Alzheimer’s disease biomarker
For the study to be successful, it’s important we have the participation of people from all walks of life and backgrounds – this means people of different ages, genders, races, ethnicities, and education levels. That’s because every brain is different, and each person’s contributions make the study’s findings that much more meaningful.
Eligible individuals must:
Be 21 to 86 years
Have and use an iPhone 8
(released in fall 2017) or later
Have access to Wi-Fi
or hardwired internet
Have an active
Have a compatible computer

*Now only enrolling ages 50–86.
After a participant completes an informed consent form and provides their permission to share data in the Intuition app, data will be collected through an Apple Watch, iPhone, and a personal computer or iPad. The types of data collected will include contact information, demographic data, Health app data, sensor and usage data from the iPhone and Apple Watch, information entered into the Intuition app such as survey responses, and the results of cognitive assessments performed on a personal computer or iPad. Participants will be able to review the data fields that will be collected as part of the onboarding process in the Intuition app.
More information about what data is collected and how it may be used is described in the informed consent form, which can be accessed at any time from the Profile tab in the Intuition app.
