This is an open access review paper ( Aug, 2018) about different tauopathies, that includes Alzheimer’s disease (AD), progressive supranuclear palsy (PSP), Parkinson’s disease (PD), Huntington’s disease (HD), Pick’s disease (PiD) and frontotemporal dementia with parkinsonism. Dr Adlard is shareholder in Prana. A very good review IMO and relates to PBT434.
