Given the challenges of replicating Parkinson’s disease in animal models, returning to models that are human-based and highly clinically characterized may provide the most successful path forward. There is a critical need to differentiate Lewy body Parkinson’s disease from other non-Lewy body forms of parkinsonism. This is important because the underlying molecular pathomechanisms, and hence potential therapeutic targets, are unlikely to be similar for both.
