Question Posted 11/08/17:

I am interested in the longitudinal data for expression and looking at the 'ADNI_Gene_Expression_Profile' matrix I see that each subject has gene expression profile at only one time point.

Could you please advise how to use this data for longitudinal data analysis or if I have missed something?

Only baseline cross sectional expression profiles are available at this time.
