Polygenic Risk Scores in Neurodegenerative Diseases: a Review

This review summarizes the current state of the art of polygenic risk scores (PRSs) in the assessment of risk for neurodegenerative diseases. Polygenic risk scores have been used to identify the shared genetic architecture between comorbid complex traits, disease presentations, and disease endophenotypes. The pathological and symptomatologic overlap between neurodegenerative diseases is strikingly high. In some cases, the diagnostic decision is...
