Abstract

Patients with dementia present epilepsy more frequently than the general population. Seizures are more common in patients with Alzheimer’s disease (AD), dementia with Lewy bodies (LBD), frontotemporal dementia (FTD) and progressive supranuclear palsy (PSP) than in other dementias. Missense mutations in the microtubule associated protein tau (MAPT) gene have been found to cause familial FTD and PSP, while the P301S mutation in MAPT has been associated with early-onset fast progressive dementia and the presence of seizures. Brains of patients with AD, LBD, FTD and PSP show hyperphosphorylated tau aggregates, amyloid-β plaques and neuropil threads. Increasing evidence suggests the existence of overlapping mechanisms related to the generation of network hyperexcitability and cognitive decline. Neuronal overexpression of tau with various mutations found in FTD with parkinsonism-linked to chromosome 17 (FTDP-17) in mice produces epileptic activity. On the other hand, the use of certain antiepileptic drugs in animal models with AD prevents cognitive impairment. Further efforts should be made to search for plausible common targets for both conditions. Moreover, attempts should also be made to evaluate the use of drugs targeting tau and amyloid-β as suitable pharmacological interventions in epileptic disorders. The diagnosis of dementia and epilepsy in early stages of those diseases may be helpful for the initiation of treatments that could prevent the generation of epileptic activity and cognitive deterioration.

  • Seizures and hyperexcitability occur more frequently in primary tauopathies than in the general population.

    “However, the possibility of seizures and hyperexcitability in primary tauopathies should not be ruled out, as they occur more frequently in these diseases than in the general population (Beagle et al., 2017; Sanchez et al., 2018).”

    From Tauopathy and Epilepsy Comorbidities and Underlying Mechanisms (2022) · cites this paper as Sanchez et al., 2018

    Section 3.2, “Seizures in PSP,” says PSP patients have seizures more frequently than the general population; Section 1 reports a higher seizure incidence in frontotemporal dementia. The paper discusses hyperexcitability in animal models but does not establish that hyperexcitability is more frequent across patients with primary tauopathies than in the general population.

  • Neurodegenerative conditions characterized by hyperphosphorylated tau aggregations exhibit increased rates of epilepsy.

    “Given that neurodegenerative conditions characterized by hyperphosphorylated tau aggregations exhibit increased rates of epilepsy, epilepsies are being re-conceptualized within a tauopathy context (Xi et al., 2011; Sanchez et al., 2018; Ali et al., 2019).”

  • Tau pathology is repeatedly found in human epilepsy.

    “Furthermore, tau pathology is repeatedly found in human epilepsy (Sanchez et al., 2018).”

  • Individuals with dementia have higher rates of epilepsy.

    “While individuals with dementia have higher rates of epilepsy, seizures are experienced more frequently in tauopathy-associated dementias like AD than in other dementias (Sanchez et al., 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
