Did you know that we can see changes in the brain that could point to (Alzheimer’s) dementia up to 10 years before the start of the first symptoms? Diagnosing (Alzheimer’s) dementia and its type can be challenging. However, an early diagnosis opens the door to future care and treatment. It would also lead to an improved understanding of dementia’s etiology and can enable timely treatment and optimize outcomes. The goal of my PhD is to diagnose dementia up to 10 years before the start of the symptoms using brain imaging.
