RESUMO
Temporal lobe epilepsy (TLE) is the most frequent focal epilepsy in adults and has been associated with psychiatric disorders (PD), especially the TLE with mesial temporal sclerosis (MTS). Electroencephalogram (EEG) could help in locating the epileptogenic zone and supply information regarding cerebral electric activity in these patients. However, there is a scarcity of knowledge about the association between EEG findings and comorbid PD in TLE. The objective of this review was to proceed a systematic review about the association of interictal EEG findings and PD in patients with TLE-MTS. A PRISMA model was used, and MEDLINE, CENTRAL, LILACS, and CAPES databases were searched. Six articles were considered in this review based on the inclusion/exclusion criteria. Results showed few published studies and contradicting conclusions regarding the association of EEG and PD in TLE-MTS. We observed great heterogeneity regarding the populations analyzed, hindering the comparison between the studies found. Studies with greater methodological robustness are needed to better understand the role of EEG as a possible biomarker for PD in TLE-MTS.
