Psychogenic epilepsy

William Szurhaj, Nicolas Engrand
About half of status epilepticus (SE) occur in patients without epilepsy. An EEG has to be performed quickly in any patient who remains unconscious after the end of convulsions with the aim to detect a subtle status. An EEG should be performed as soon as possible in case of suspicion of non-convulsive status epilepticus, or in case of a confusional state whose origin remains unknown. The realization of a cerebral imaging is very often necessary in case of inaugural SE, as soon as the patient's condition allow it...

OBJECTIVE: Mitigation of suicide risk by reducing access to lethal means, such as firearms and potentially lethal medications, is a highly recommended practice. To better understand groups of patients at risk of suicide in medical settings, the authors compared demographic and clinical risk factors between patients who died by suicide by using firearms or other means with matched patients who did not die by suicide (control group). METHODS: In a case-control study in 2016 from eight health care systems within the Mental Health Research Network, 2,674 suicide cases from 2010-2013 were matched to a control group (N=267,400)...

OBJECTIVES: The objective of the study was to access the suicide risk (SR) in patients with refractory epilepsy and its association with temperament and sleep quality. METHODS: A total of 50 consecutive patients referred for epilepsy surgery evaluation in the Porto Alegre Epilepsy Surgery Program were included. All patients had a detailed neurologic and psychiatric evaluation, including video-electroencephalogram (VEEG), high-resolution magnetic ressonance imaging (MRI), and neuropsychologic assessment...

OBJECTIVE: Psychogenic nonepileptic seizure (PNES) is a common diagnosis after evaluation of medication resistant or atypical seizures with video-electroencephalographic monitoring (VEM), but usually follows a long delay after the development of seizures, during which patients are treated for epilepsy. Therefore, more readily available diagnostic tools are needed for earlier identification of patients at risk for PNES. A tool based on patient-reported psychosocial history would be especially beneficial because it could be implemented in the outpatient clinic...

In epilepsy, individual seizures can be triggered by a variety of external and internal stimuli. One of the most common trigger factors reported by patients is stress. However prevalent, stress-related triggering of episodes seems underappreciated in epilepsy for various reasons, and its misinterpretation often leads to other diagnoses, e.g., psychogenic nonepileptic seizures (PNES) or normal reactions. This article illustrates the significant role of stress as a seizure-provoking factor by referring to nine patient narratives...

PURPOSE: The interictal dysphoric disorder (IDD) is a proposed epilepsy-specific psychiatric condition characterized by a conglomerate of symptoms such as depression, irritability, euphoria, and anxiety. However, there are doubts about IDD as an independent entity and about its presumed epilepsy-specific nature. METHODS: Here, we investigated the association between psychiatric disorders and IDD in 120 patients with epilepsy, also analyzing potential associations between IDD symptoms and epilepsy-related variables...

Sleep-related hypermotor epilepsy (SHE) (previously frontal lobe epilepsy) is a rare seizure disorder commonly misdiagnosed or unrecognized, causing negative patient sequelae. While usually reported in familial studies, it is more commonly acquired. Diagnosis is a challenge due to its low incidence in comparison with the more common sleep disorders or psychogenic etiologies in the differential diagnosis. Diagnosis is scaled on degree of certainty based on described or clinically documented semiology, with video EEG as a helpful, but not necessary, adjunct...

BACKGROUND AND PURPOSE: Misdiagnosis of refractory epilepsy (rE) is common and such patients experience a long diagnostic delay. Our aim was to identify key clinical/laboratory factors in order to obtain an alternative diagnosis in patients referred for rE. METHODS: Between January 2010 and December 2015, 125 consecutive patients with a diagnosis of rE were prospectively enrolled. All patients underwent a comprehensive neurological, neuropsychiatric and cardiologic evaluation, and had an observation time of at least one year after the study entry...

Studies of emotion processing are needed to better understand the pathophysiology of psychogenic nonepileptic seizures (PNES). We examined the differences in facial emotion processing between 12 patients with PNES, 12 patients with temporal lobe epilepsy (TLE), and 24 matched healthy controls (HCs) using fMRI with emotional faces task (EFT) (happy/sad/fearful/neutral) and resting state connectivity. Compared with TLE, patients with PNES exhibited increased fMRI response to happy, neutral, and fearful faces in visual, temporal, and/or parietal regions and decreased fMRI response to sad faces in the putamen bilaterally...

The purpose of this review is to provide an update of the research regarding the etiology, diagnosis and management of psychogenic non-epileptic seizures (PNES). A literature search using Pubmed, Ovid MEDLINE and EMBASE database was performed from 2000 up to August 2017. We have evaluated the different factors leading to PNES as well as the diagnostic approach and management of this disorder which continue to be very difficult. The coexistence of epilepsy and PNES poses special challenges and requires the coordinated efforts of the family physicians, psychiatrists, psychologists and neurologists...

Autoimmune encephalopathies are clinically and immunologically heterogeneous disorders. At least 20 types of autoimmune encephalopathies have been discovered, with the most common type being Hashimoto encephalopathy. In clinical situations, we often observe that patients with autoimmune encephalopathy are misdiagnosed because they exhibit signs similar to those observed in functional psychogenic movement, conversion, or somatoform disorders. We clinically examined over 100 patients with autoimmune encephalopathy...

OBJECTIVE: Specialized epilepsy clinics receive many cases (20%-30% of total cases) in which the patients are diagnosed with psychogenic non-epileptic seizures (PNES). In Puerto Rico, there has been a lack of research on and data about patients with PNES. This study examined the clinical profile of 34 patients with a confirmed diagnosis of PNES. METHODS: A secondary analysis of 34 clinical records of patients with PNES was conducted. The resulting profile was based on clinical interviews, the behavioral presentation of seizures, the history of traumatic experiences or abuse, and the relationship between PNES events and life stressors...

OBJECTIVE: The objective of the study was to determine whether male and female populations of patients with psychogenic nonepileptic seizures (PNES) differ, in terms of demographic, social/clinical, and etiological factors as well as psychological measures. BACKGROUND: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes...

OBJECTIVE: Studies from a small number of countries suggest that patients with psychogenic nonepileptic seizures (PNES) have limited access to diagnostic and treatment services. The PNES Task Force of the International League Against Epilepsy (ILAE) carried out 2 surveys to explore the diagnosis and treatment of PNES around the world. METHODS: A short survey (8 questions) was sent to all 114 chapters of the ILAE. A longer survey (36 questions) was completed by healthcare professionals who see patients with seizures...

PURPOSE: Questionnaires investigating semiology and comorbidities of psychogenic non-epileptic seizures (PNES) have been used mainly to help physicians expedite referrals to epilepsy centres for confirmation of diagnosis rather than as alternative diagnostic tool when video-EEG monitoring (VEM), the current gold standard, is not available or is inconclusive. METHODS: We developed one structured questionnaire for patients, exploring subjective experiences and vulnerabilities and one for eyewitnesses, focused on features observable during typical events to study prospectively 50 consecutive adult patients with PNES or epileptic seizures (ES) admitted for VEM...

Psychogenic nonepileptic seizures (PNES), often mistaken for epilepsy in community practice, require inpatient video-EEG (VEEG) monitoring for diagnostic confirmation. We developed a simple score designed for use in an outpatient setting to predict the subsequent VEEG diagnosis of PNES. We retrospectively compared fifty-five consecutive patients with VEEG-proven PNES (N1 =55) with a group of randomly selected patients with VEEG-proven epilepsy (N2 =55). Patients were divided into two groups: I) a 'truly retrospective' group of 27 patients with PNES and 27 patients with epilepsy whose data served to develop the score, and II) a 'pseudoprospective' group of 28 patients each with PNES and epilepsy to whom the score was applied...

BACKGROUND: There is lack of consensus regarding driving restrictions for patients with epilepsy. Regulations vary by state. New York State (NYS) recommends driving restrictions for one year in a person with an episode of loss of consciousness (LOC), with physician discretion. Often, providers make recommendations to permit their patients to drive after a shorter seizure-free period than proposed guidelines. The prevalence and reasons behind more lenient recommendations have not been elucidated...

PURPOSE: To investigate if psychiatrists could predict the diagnosis of psychogenic nonepileptic seizures (PNES) by reviewing videos of seizures of various types and to compare the accuracy and the criteria leading to the diagnosis used by psychiatrists with those used by epileptologists. METHODS: Four board-certified psychiatrists were asked to review 23 videos capturing representative events of 21 unselected consecutive patients admitted to an epilepsy center for long-term video-EEG monitoring...

BACKGROUND: Optimal anti-epileptic drug (AED) treatment maximises therapeutic response and minimises adverse effects (AEs). Key to therapeutic AED treatment is adherence. Non-adherence is often related to severity of AEs. Frequently, patients do not spontaneously report, and clinicians do not specifically query, critical AEs that lead to non-adherence, including sexual dysfunction. Sexual dysfunction prevalence in patients with epilepsy ranges from 40 to 70%, often related to AEDs, epilepsy or mood states...
