Among the subjects with CTE, this study reports (1) mean age at time of symptom onset and death were both higher in CTE subjects with Aβ, (2) Aβ deposition was significantly associated with presence of APOE e4 allele, (3) Aβ deposition was correlated more significant Tau deposition independent of age, and (4) Aβ presence was a strong predictor for both Lewy-Body co-morbidity and dementia independent of age (Stein et al., 2015). Here, MAPT is linked to dementia.
