The Alzheimer’s disease research community has shifted vision to early detection of the disease. “We need to use biomarkers to try to understand if they have underlying neurodegeneration or some other reason. For patients headed for Alzheimer’s disease, we [could] do intervention.”
Faculty researchers studying Alzheimer’s disease at IU School of Medicine perform molecular, genetic and imaging-based analysis of patients, looking for biomarkers that may predict onset of the disease and present new therapeutic targets. These investigators are examining 25 leading candidate genes while pursuing exciting new avenues for research and discovering new facets of the disease.
A major component of the Alzheimer’s disease research program at IU School of Medicine is the Indiana Alzheimer Disease Center, a multidisciplinary research program intensely committed to the U.S. National Alzheimer’s Project Act (NAPA) to prevent and effectively treat Alzheimer disease by 2025. Major activities include innovative research on causes, early detection and treatment, including both pharmacological and non-drug approaches as well as interventions for caregivers and educational programs for researchers and members of the community. The Indiana Alzheimer Disease Center is part of a network of centers and programs working to rapidly find a cure for Alzheimer’s disease.
International expertise: Imaging, data science and translational research
A multi-dimensional approach
“It’s become increasingly clear that Alzheimer’s disease is a complex disorder,” states Andrew Saykin, PsyD, Raymond C. Beeler Professor of Radiology and Imaging Sciences and Director of the Indiana Alzheimer Disease Center and the Indiana University Center for Neuroimaging. “We need to take a multi-dimensional approach.” The faculty of the centers are taking innovative approaches to examine exciting new avenues for research and discovering new facets of the disease. “Beta-amyloid and Tau [proteins] are important, but they’re not enough to explain the disease.”
Capturing real-time changes in the brain
Alzheimer’s disease research has grown considerably; it used to be only diagnosed post mortem. Now, researchers can examine real-time changes in the brain in Alzheimer’s patients. These quantitative phenotypes can be measured using a variety of imaging techniques, including positron emission tomography (PET) scans and multiple advanced magnetic resonance (MR) imaging techniques and modalities.
The research group is also working on noninvasive measurements of brain architecture that give a quantitative readout during memory tasks patients are asked to perform while in the scanner. The researchers are just beginning to scratch the surface of possibilities, pairing genetic and imaging data to better understand the disease and its progression.
Gene sequencing with super computers
Advanced imaging technology
While imaging technology and research evolves to allow earlier detection of Alzheimer’s disease, it also means analysis of Alzheimer’s disease patients on an individual level. The center continues to produce data and make discoveries that fall in line with the IU Precision Health Initiative.
Longitudinal Early-Onset Alzheimer’s Disease Study (LEADS)
Neuroscience is targeting Alzheimer’s disease.
Alzheimer disease has been at the forefront of neuroscience due to substantive innovations in molecular biology, genetics, neuropathology and imaging technologies. IU School of Medicine training curriculum ensures that emerging physicians and physician-scientists are prepared to advance progress to prevent and effectively treat this devastating disease.
Internationally recognized, world-class faculty researchers
