Question Posted 04/14/25:
Dear Experts, I am hoping to ask whether, in the dataset ADNIMERGE (downloaded from IDA in April, 2024), the variable "PTAU" indicates CSF p-Tau181 measurements. I was not able to find details in the data dictionary. I apologize for sending this question again as I am not sure if I directed it to the correct core the first time. Thank you so much for your help!

I would recommend you look into the biofluid source data and corresponding data dictionary rather than ADNIMERGE. The CSF & plasma datasets have PDF documents describing each measurement, and the spreadsheet data is also defined in the data dictionary. That way you can be sure of exactly what the measurement is.
