Any abnormal hypersynchronus activity of neurons can be characterized as an epileptic seizure (ES). A broad class of non-epileptic seizures is comprised of Psychogenic non-epileptic seizures (PNES). PNES are paroxysmal events, which mimics epileptic seizures and pose a diagnostic challenge with epileptic seizures due to their clinical similarities. The diagnosis of PNES is done using video-electroencephalography (VEM) monitoring. VEM being a resource intensive process calls for alternative methods for detection of PNES...

Psychogenic non-epileptic seizures (PNES) have a high prevalence globally but the accurate diagnosis of this condition still remains a challenge. This is particularly the case in countries where there is scarce expertise and insufficient affordable medical facilities to which patients have access. The rate of PNES diagnosis in epilepsy units is typically within the range of 20 to 30%. In the context of developing countries, this rate tends to be higher and increases demand on the existing scarce health care capacities...

OBJECTIVES: Psychopathology levels are elevated in patients with psychogenic non-epileptic seizures (PNES) and those with epilepsy. However, patients with PNES report higher rates of trauma and neglect, poorer health-related quality of life (HRQoL), and an increased prevalence of insecure attachment. We examined to what extent attachment style and relationship quality with their main informal carer impact on levels of HRQoL, depression, and anxiety in patients with PNES versus those with epilepsy...

OBJECTIVE: Although there is general consensus that psychogenic non-epileptic seizures (PNES) are treated with psychotherapy, the effectiveness of most psychotherapeutic modalities remains understudied. In this treatment series of 16 patients dually diagnosed with PNES and post-traumatic stress disorder (PTSD), we evaluated the effect of prolonged exposure therapy (PE) on reduction of PNES. Secondary measures included Beck Depression Inventory (BDI-II) and Post-Traumatic Disorder Diagnostic Scale (PDS)...

BACKGROUND AND OBJECTIVE: Although many patients present with functional neurological symptoms (FNS), few US clinics offer specialized FNS care, and data on clinic attendees remain limited. We determined predictors of initial attendance, symptom burden, and FNS subtype in the first patients referred to our Functional Neurological Disorders Clinic for suspected FNS. METHODS: We reviewed the charts of 62 consecutive patients (46 women, 16 men). Regression analyses investigated predictors of keeping the first scheduled clinic appointment...

Psychogenic non-epileptic seizures (PNES) are seizures which clinically resemble epileptic seizures but are without concurrent abnormal electrical charges. Though PNES can be just as serious and disabling as epileptic seizures, specific treatment guidelines are lacking, and different types of treatments are used. In this article we address the current research on psychotherapeutic treatment for PNES by discussing recent reviews and six randomized controlled trials (RCTs) on the subject. In conclusion, larger well-designed RCTs are needed in order to support the evidence for psychological interventions for this patient group...

PURPOSE: There have been a number of studies exploring treatments for psychogenic non-epileptic seizure (PNES) but largely neglecting the sizable subgroup of patients with intellectual disability (ID). In the present study, we attempted to demonstrate effects and preferred modes of therapeutic intervention in PNES patients with ID being treated at a Japanese municipal center with a short referral chain. METHODS: We examined 46 PNES patients with ID (ID group) and 106 PNES patients without ID (non-ID group) retrospectively in case charts...

Psychogenic non-epileptic seizures (PNES) resemble epileptic seizures, but lack clinically evident abnormal electrical activity in the brain. We aimed to assess resting gamma spectral power, current source distribution and functional connectivity in adolescents with PNES. Interictal, 32 channels electroencephalographic recording of 15 adolescents with PNES was compared with 10 matched healthy controls. Spectral power, current source distribution and lagged linear coherence were assessed. Statistically significant gamma spectral power, cortical sources and connectivity pattern was found in some brain areas...

BACKGROUND: Spatiotemporal analysis of electroencephalography is commonly used for classification of events since it allows capturing dependencies across channels. The significant increase of feature vector dimensionality however introduce noise and thus it does not allow the classification models to be trained using a limited number of samples usually available in clinical studies. NEW METHOD: Thus, we investigate the classification of epileptic and non-epileptic events based on temporal and spectral analysis through the application of three different fusion schemes for the combination of information across channels...

Psychogenic non-epileptic seizures (PNES) are diagnosed in at least 10-40% of the patients seen for long-term monitoring of epilepsy, and it is no surprise that patients with PNES are often treated for epilepsy. Given the substantial economic costs and mental health burden of misdiagnosis, it is imperative to establish early identification, correct diagnosis, and effective treatment of PNES in order to provide the greatest opportunity for remission of events, improved psychological functioning, and social-vocational outcome...

Epilepsy monitoring unit (EMU) admissions are essential for the classification/localization of epileptic seizures (ES) and psychogenic non-epileptic seizures (PNES). However, the duration of admissions is highly variable. Accordingly, we evaluated the duration of 596 EMU admissions and reasons for prolonged (>7 days) lengths of stay (LOS). The average LOS was longer for patients diagnosed with ES (8.0 days, SD 4.1 days) than all others (6.0 days, SD 3.9 days, p<0.001). Of the 596 admissions, 231 (38.8%) had prolonged LOS...

OBJECTIVE: Recent studies have attempted to compare patients affected by psychogenic non-epileptic seizures (PNES) to patients affected by functional motor symptoms (FMS) from a demographic, clinical and psychological perspective. Nevertheless, results are quite controversial and significant conclusions have not been drawn. The aim of our study was to evaluate the phenomenology of psychology of the two groups assessing levels of dissociation and its subcomponents, alexithymia and interoceptive sensitivity in patients with PNES and in patients with FMS...

OBJECTIVE: To compare the performance of 4h-video EEG monitoring (VEEG) and 1h-nap-VEEG in an Epileptology Unit. METHODS: We examined short-term VEEG data from 196 patients admitted to characterize their: (i) clinical events; (ii) epileptic syndromes or (iii) state after status epilepticus or surgery. We compared the 4h-VEEG and 1h-nap-VEEG performances using three measures: (i) the capability to detect epileptic seizures (ES), psychogenic non-epileptic seizures (PNES), interictal epileptiform abnormalities (IEA) and sleep-related IEA; (ii) the usefulness to answer questions on referral; (iii) the sensitivity for the final diagnosis...
