Figure 5. Follow-up Information for ALT Cases.

Figure 5

(A) Clinical diagnosis over time for 45 amyloid+ with low tau (ALT) cases numbered sequentially. (B) Posterior probability of elevated tau over time for a subset of 23 individuals identified by ALT case number who had more than 1 tau PET scan at least 5 years after the first abnormal amyloid scan. For both panels, zero on the X-axis corresponds to the time of the individual's first abnormal β-amyloid (Aβ) scan. CN = cognitively normal; MCI = mild cognitive impairment.
