Researchers believe that intervention at the earliest possible stage of the disease may be an effective way to prevent or reduce the development of Alzheimer’s dementia from the asymptomatic stage or the stage of subjective cognitive decline or mild cognitive impairment (MCI).

For this purpose, the AMYPAD prognostic study has analysed ß-amyloid PET scans from a large population of healthy research participants and research participants who are at the earliest stages of Alzheimer’s disease, to understand the window of opportunity for secondary prevention through ß-amyloid imaging.
