Memory and language risk assessment with Wada test in patients candidates for epilepsy surgery.

Aim: To determine post-surgical cognitive risk and associated factors according to lesion location in a sample of patients evaluated for epilepsy surgery with Wada test at the Fundacion Instituto Neurologico de Colombia.

Materials And Methods: An observational, retrospective, analytical study was completed in patients with drug-resistant temporal lobe epilepsy candidates for epilepsy surgery treated from 2001 to 2021, who completed the Wada test as part of the pre-surgical evaluation. A descriptive analysis of sociodemographic, clinical, imaging and neuropsychological variables was completed; a multivariate logistic regression was performed analyzing factors associated with resection risk in patients with left lesions.

Psychogenic non-epileptic and epileptic seizures: clues for a differential diagnosis. Findings from a Colombian study.

Introduction: Psychogenic non-epileptic seizures (PNES) are paroxysmal changes in behavior that resemble epileptic seizures, although they have no electrophysiological correlation or clinical evidence of epilepsy.

Aim: To compare clinical and sociodemographic characteristics of patients diagnosed with PNES-alone and PNES-and-epilepsy.

Patients And Methods: A cross-sectional study of consecutive patients diagnosed with PNES in a 20-month period was carried out.
