Changes in Attentional Control After a Focal Seizure.

NCT06466681 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 100

Summary

Epilepsy is frequently associated with cognitive and attentional disorders. Several studies have pointed out that there are modifications of brain activity in resting state during peri-ictal period in EEG and functional MRI. However, to date, no study has assessed the changes in attentional control after a seizure. The investigators hypothesize that a localized discharge is associated with a disorganization of the networks engaged in attentional control. In this regard, the investigators propose a prospective longitudinal study assessing the changes in attentional control after a focal seizure.

Conditions

  • Temporal Lobe Epilepsy
  • Frontal Lobe Epilepsy
  • Others Subtypes

Interventions

OTHER

All included subjects

Administration of the subtest of divided attention of the Test of Attentional Performance (TAP), recording of the event related potentiels N200 and P300, measure of the variation of power in several frequency bands (theta, alpha and beta) and measure of the high-resolution EEG connectivity during an attentional task at several time-points : a first time during interictal period (no seizure for more than 24 hours) and 1, 3, 6 and 24 hours after a focal seizure.
