Quality of Life and Psychogenic Nonepileptic Seizures.

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to identify the prognostic factors of quality of life in patients with psychogenic non-epileptic seizures

Detailed Description
-----------------
This is a monocentric prospective study. Our main objective is to identify prognostic factors associated with an improvement of quality of life on the QOLIE-31 and Short Form Health Survey SF-36 at six months from the diagnostic. We hypothesized that the absence of PNES during the last three-months before the six months follow-up visit is the best prognostic factor for an improvement of quality of life All adult (>15 years and 3 months) patients diagnosed with PNES will be prospectively included. All patients will undergo standard of care and have consultation with neurologist and a psychiatrist trained for this type of disease, as it is usually made for these patients (no intervention allocated in the context of the research). . Announcement of diagnostic will be standardized and adapted to each patient. Clinical and demographic data will be collect as well as medical and psychiatric history. All patients will undergo prolonged electroencephalogram (EEG) under video monitoring allowing the diagnostic of PNES and ruling out epilepsy. Different neurologic and psychiatric scales will be collected (Quality of life in epilepsy - 31 quotes (QOLIE-31), Short Form Health Survey (SF-36), Montreal Cognitive Assessment (MoCA), Beck Depression Inventory (BDI2), Beck Anxiety index (BAI), Clinician administrated Post traumatic stress disorder scale (CAPS), Chilhood Trauma Questionnaire (CTQ), Epworth). All patients will be oriented to psychiatric or psychological follow-up. Patients will undergo a one, three and six months follow-up and will be evaluated the number of seizure, their severity, and psychiatric or psychological follow-up will be evaluated. Patients will undergo scales (QOLI-31, SF-36, BDI2, BAI).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| One cohorte : patient psychogenic nonepileptic seizures<br>The Psychogenic nonepileptic seizures (PNESs) are paroxysmal episodes type of abnormal movements, behavior modification or alteration of the contact-like seizures. These episodes are involuntary and underpinned by an unconscious psychological processes. In the International Classification of Disease-10 (ICD-10), they are classified as dissociative phenomena as conversing syndromes in the Manual of Diagnostic and Statistical Mental Disorders-IV (DSM-IV). The participants of the study only receive the usual care they would have if they were not included (no new/different intervention allocated in the study). | |
