Relationship between epileptic seizures and criminal behavior: A Systematic Literature Review

Resumen

Objective: The principal objective aims to assess a possible relationship between epilepsy and aggressive behavior. Secondarily, we intend to study how epilepsy relates to criminal liability. Methods: A systematic literature review was performed, using the Web of Science,United States National Library of Medicine (PubMed),and Scielo databases. The searches were conducted in May-June 2022 and covered the period from 2000 to 2022. Eligibility criteria consisted on original articles in English and Portuguese that were interested in the association of epilepsy, criminal behavior (with aggression directed to others), criminal liability in adults with epilepsy. Results: The search yielded 921 results, 794 of which in PubMed, 115 in Web of Science, and 12 in Scielo. Articles that failed to meet the inclusion criteria (206) and duplicates (201) were excluded. Conclusion: There were no findings to indicate a significant increase in aggressive behaviors in individuals with epilepsy. However, it was possible to identify a higher prevalence of aggressive acts in males with epilepsy, besides the presence of comorbidities with mental disorders and substance use. In addition, the results suggest that in criminal offenders with epilepsy, the seizures originated in the temporal and frontal cerebral lobes. Further researchis necessary on the relationship between epilepsy, criminality, and criminal liability in order to produce more robust data to support legal proceedings.
