Question

Question Posted 03/02/15:
I would like to know how the DXCHANGE variable is assigned in the diagnostic summary file. Is it using only clinical tests like MMSE, CDR, ADAS-COG etc. or is MRI/PET also taken into account? Is there a written record of this information somewhere?

Thank you very much for your time!
