In our previously published epilepsy post‐mortem cohort of mixed aetiologies (from the Epilepsy Brain and Tissue Bank at UCL), which predated recent diagnostic criteria for CTE, we noted astroglial tau in 35%, sulcal tau in 5.8%, perivascular tau in 6.5% and a correlation of tau load with a history of TBI [9]. Here, MAPT is linked to epilepsy.
