    Abstract

    Objective

    Ictal injuries have long been considered typical signs of epileptic seizures. However, studies have shown that patients with functional seizures (FS) – also named psychogenic non-epileptic seizures – can also present these signs, misleading physicians and delaying a correct diagnosis. This systematic review aimed to assess the prevalence of injuries from FS.

    Methods
    A literature search was performed in PubMed, Embase, LILACS, Scopus, Web of Science, PsycINFO, Google Scholar, OpenGrey, and ProQuest. Observational studies were included. The risk of bias was assessed using the JBI checklist for studies reporting prevalence data. RStudio was used for meta-analyses. Cumulative evidence was evaluated according to GRADE criteria.

    Results
    From the 2,607 identified records, 41 studies were included in the qualitative synthesis, and 28 were included in meta-analyses. A meta-analysis of 13 studies, including 1,673 individuals, resulted in an overall lifetime prevalence of injuries due to FS per person of 25% (95% CI 19%-32%; I2 = 88%). Considering a limited period (VEEG monitoring days), a meta-analysis of 13 studies, including 848 individuals, resulted in an injury prevalence due to FS per person of 0.7% (95% CI 0%-3%; I2 = 73%). Also, a meta-analysis of 8 studies, including 1,000 individuals, resulted in a prevalence of injuries per FS of 0.1% (95% CI 0%-0.98%; I2 = 49%). The certainty in cumulative evidence assessed by GRADE was rated “very low” for lifetime prevalence of injuries per person, “low” for prevalence per person during VEEG monitoring, and “moderate” for prevalence per number of FS.

    Significance
    Overall pooled lifetime prevalence of injuries due to FS per person was 25%. In comparison, the prevalence of injuries per person during VEEG monitoring and per functional seizure was 0.7% and 0.1%, consecutively. The evidence of the occurrence of injuries due to FS breaks the paradigm that epileptic seizures can cause injuries, but FS cannot.

    Ictal injuries seem to be injuries caused by seizures e.g. tongue biting, bruising. I haven't read the study, but from the abstract, it looks to be simply concluding that the fact that someone is injured by their seizure doesn't mean it's not psychosomatic.
