Summary
Neuroimaging advances allow measurement of tau and beta-amyloid (Aβ) proteins, enhancing our understanding of Alzheimer's disease mechanisms. This research is vital for developing new biomarkers and targeted therapies for Alzheimer's disease.
Area of Science:
- Neurology
- Radiology
- Biochemistry
Background:
- Alzheimer's disease (AD) is a progressive neurodegenerative disorder.
- Accurate characterization of AD pathogenesis is crucial for therapeutic development.
- Neuroimaging plays a pivotal role in understanding AD mechanisms.
Purpose of the Study:
- To review the contribution of neuroimaging studies to understanding Alzheimer's disease.
- To highlight how advanced imaging techniques characterize AD mechanisms.
- To discuss the role of tau and beta-amyloid (Aβ) in AD.
Main Methods:
- Utilized tau and Aβ Positron Emission Tomography (PET).
- Employed [18F]fluorodeoxyglucose (FDG) PET and Magnetic Resonance Imaging (MRI).
- Analyzed multimodal imaging data to investigate disease mechanisms.
Main Results:
- Neuroimaging reveals phenotypic variability in AD, linked to clinical presentation and age.
- Multimodality analyses elucidate relationships between imaging markers and disease processes.
- Early-stage neuroimaging changes identified in preclinical AD and autosomal dominant AD mutations.
Conclusions:
- Neuroimaging, particularly tau and Aβ PET, advances Alzheimer's disease understanding.
- Findings emphasize the roles of tau, Aβ, age, and comorbidities in neurodegeneration.
- This knowledge is essential for developing improved AD biomarkers and therapeutics.
