There is significant clinical heterogeneity in clinical phenotypes even within classical neurodegenerative disease categories of Alzheimer’s disease, Fronto-temporal dementia, Lewy body dementia etc. Clinical phenotypes include differences in predominant symptoms (e.g., language, behavior, judgment, neuropsychiatric, memory) and differences in rate of progression and outcomes. It is increasingly recognized that there are underlying differences in genetic and molecular pathologies that drive the differences in these clinical phenotypes. Understanding this in detail is key to providing future precision medicine therapies targeting chronic neurodegenerative diseases.
Mapping the interrelationships between the underlying molecular changes to clinical phenotype is informed by bioinformatics and novel data analysis methods that take insights from clinical medicine, cognitive neuroscience, neuroimaging, genetic and transcriptomic data, protein biomarkers, and neuropathology to uncover key drivers.
Using these tools, we aim to: 1) develop clinical biomarkers to predict outcomes of interest in neurodegenerative diseases, and 2) develop precision medicine therapies targeting key pathological drivers.
