Molecular PET Imaging and Plasma Biomarkers in Alzheimer´s Disease and Other Neurodegenerative Diseases

Multi-PET /MRI studies , fluid biomarkers (CSF, plasma) analysis, neuropsychological testing is performed in subjects carriers and non-carriers of different APP, PS autosomal dominant AD mutatation. Both presymptomatic and symptomatic carriers and non-carriers are recruited (age range -30 to +15 years from first clinical symptoms). For comparison also a group of healthy eldersly as well as patients undergoing memory assessment with diagnosis of mild cognitive impairment (amyloid negative /amyloid positive) and diagnosis sporadic Alzheimer´s diases are recruited from Karolinska memory clinic and undergoing similar Multi-PET/MRI studies , fluid biomarker analysis, neuropsycholigal testing. The aim is to describe the evolution and spreading of tau in brain in Alzheimer continuum and compare with other pathological markers with aim of develop new diagnostic markers and therapeutic targets.
