In the file SEA-ADindividualmetadata.xlsx from Synapse project id: syn2580853, I see various diagnostic metrics such as 'Cognitive status', 'diagnosis', and 'Consensus clinical diagnosis'. With regards to Consensus clinical diagnosis I was wondering what the exact definition is. It is NOT to be found in the dictionary or values tabs of the aforementioned file. Additionally with regards to consensus clinical diagnosis, what does 'Control' mean compared to neurotypical references. Who are 'Control' as by 'Consensus clinical diagnosis' and do they have some spectrum of AD? Clarification would be appreciated. Best, Ashay
