What this research studies
Researchers will use big neuroimaging datasets and clinical information from people with Alzheimer’s to map how disease-related brain degeneration affects circuits tied to emotion and behavior. They will apply advanced computational methods and the NIMH RDoC framework together with the Triple Network model (default mode, central executive, and salience networks) to link circuit changes to specific neuropsychiatric symptoms. Most work involves analyzing existing brain scans (like fMRI) and clinical records, but findings may guide future scans or assessments for patients. The goal is to clarify why common treatments often fail for these symptoms in Alzheimer’s.
Who could benefit from this research
Good fit: People diagnosed with Alzheimer’s disease, especially those who are experiencing neuropsychiatric symptoms such as depression, anxiety, agitation, aggression, or apathy, are the main focus.
Not a fit: People without Alzheimer’s disease or whose symptoms are caused primarily by other medical or psychiatric conditions may not see direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could point to more precise ways to predict, monitor, or treat mood and behavior problems in people with Alzheimer’s disease.
How similar studies have performed: Prior imaging studies have linked network disruptions to psychiatric symptoms, but combining very large neuroimaging datasets with RDoC and advanced computational approaches in Alzheimer’s is relatively new.
