MAPT and epilepsy: However, the presence of tau pathology in childhood or adolescent-onset epilepsies, such as Dravet syndrome, Nodding syndrome, Lafora disease, NPC, TSC, and ASD, and in relatively younger TLE patient cohorts (Puvenna et al., 2016; Smith et al., 2019; Gourmaud et al., 2020) suggest a causal link between seizure activity and p-tau accumulation.
