The aim of our research is to investigate early risk factors (both genetic and life-style related) of memory disorders and especially Alzheimer’s Disease. We collaborate with the local AURIA biobank, which enables us to recruit study participants according to a specific risk genotype for Alzheimer’s disease. We also collaborate with the Finnish Institute for Health and Welfare to recruit individuals with midlife metabolic risk factors and thus at an increased risk for late-life dementia. We are specialized in multimodal neuroimaging where we combine radiotracers with different targets in the brain (for example beta-amyloid, activated microglia, synaptic vesicles) and MRI imaging to examine how early cerebral changes of memory disorders associate with each other.
