Abstract

Epilepsy is the third most common chronic brain disorder, and is characterized by an enduring predisposition to generate seizures. Despite progress in pharmacological and surgical treatments of epilepsy, relatively little is known about the processes leading to the generation of individual seizures, and about the mechanisms whereby a healthy brain is rendered epileptic. These gaps in our knowledge hamper the development of better preventive treatments and cures for the approximately 30% of epilepsy cases that prove resistant to current therapies. Here, we focus on the rapidly growing body of evidence that supports the involvement of inflammatory mediators-released by brain cells and peripheral immune cells-in both the origin of individual seizures and the epileptogenic process. We first describe aspects of brain inflammation and immunity, before exploring the evidence from clinical and experimental studies for a relationship between inflammation and epilepsy. Subsequently, we discuss how seizures cause inflammation, and whether such inflammation, in turn, influences the occurrence and severity of seizures, and seizure-related neuronal death. Further insight into the complex role of inflammation in the generation and exacerbation of epilepsy should yield new molecular targets for the design of antiepileptic drugs, which might not only inhibit the symptoms of this disorder, but also prevent or abrogate disease pathogenesis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Blood-brain barrier breakdown caused by traumatic brain injury and underlying inflammatory reactions can trigger epilepsy.

    “BBB breakdown caused by TBI and underlying inflammatory reactions can trigger epilepsy (204, 618).”

    From Blood-Brain Barrier: From Physiology to Disease and Back (2019) · cites this paper as [618]

    In “Does inflammation cause cell loss?” (page unavailable), the review says TBI causes tissue inflammation that seems to contribute to long-term hyperexcitability and describes injury-related inflammation as a possible contributor to epilepsy in adult rodents. It also reports BBB breakdown alongside vascular inflammation in epilepsy models, but the passages do not establish that TBI-caused BBB breakdown triggers epilepsy. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The cells of the NVU, especially glial cells, have an overwhelming importance in epileptogenesis.

    “Taking all the recent data into consideration, we can suggest that the cells of the NVU, specially glial cells, have an overwhelming importance in epileptogenesis.”

    From The impact of microglial activation on blood-brain barrier in brain diseases (2014) · cites this paper as Vezzani et al., 2011

  • Inflammatory pathways activated by microglial cells induce BBB dysfunction, which contributes to epileptogenesis.

    “These current findings show the increasing importance of the inflammatory pathways activated by microglial cells in inducing BBB dysfunction, which contributes to epileptogenesis.”

    From The impact of microglial activation on blood-brain barrier in brain diseases (2014) · cites this paper as Vezzani et al., 2011

  • In epilepsy, chronic seizures lead to excitotoxicity and neuronal apoptosis with associated gliosis.

    “In epilepsy, chronic seizures lead to excitotoxicity and neuronal apoptosis with associated gliosis [188].”

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.
