Precision medicine of frontotemporal dementia: from genotype to phenotype.

Frontotemporal dementia (FTD) is the second most common neurodegenerative  cause of early-onset dementia. FTD has an important genetic component contributing to its pathogenic mechanisms. Currently, extensive research on neuroimaging biomarkers and neurochemical biomarkers in FTD is being conducted to address the clinical need for a sensitive and specific diagnostic marker. Here, we review the advances in genetics, biomarkers and treatment of FTD and how this may represent a shift towards precision medicine. To advance the clinical use of precision medicine, big data cohort for genotype/phenotype research and multidisciplinary team approaches are necessary.
