Integrated care for mental health in epilepsy: A systematic review and meta-synthesis by the International League Against Epilepsy Integrated Mental Health Care Pathways Task Force.

Mental health (MH) comorbidities are prevalent among people with epilepsy (PWE), but many experience challenges accessing care. To address this, suggestions have been made to integrate MH care into epilepsy care settings, yet the current approaches, benefits, and implementation determinants to MH care integration are unclear. This review aims to synthesize existing integrated MH care models for PWE to inform the development and planning of future initiatives.

Functional neurological disorder, physical activity and exercise: What we know and what we can learn from comorbid disorders.

Functional neurological disorder (FND) is a common neurologic disorder associated with many comorbid symptoms including fatigue, pain, headache, and orthostasis. These concurrent symptoms lead patients to accumulate multiple diagnoses comorbid with FND, including fibromyalgia, chronic fatigue syndrome, postural orthostatic tachycardia syndrome, persistent post-concussive symptoms, and chronic pain. The role of physical activity and exercise has not been evaluated in FND populations, though has been studied in certain comorbid conditions.

Functional Neurological Disorder Presenting After Concussion: A Retrospective Case Series.

Objective: Although a majority of individuals recover from a concussion within weeks of the index injury, a substantial minority of patients report persistent postconcussion symptoms. Some of these symptoms may reflect a diagnosis of functional neurological disorder (FND). The authors evaluated the relationship between persistent postconcussion symptoms and FND symptoms.

Prevalence of autoimmune diseases in functional neurological disorder: influence of psychiatric comorbidities and biological sex.

Background: Functional neurological disorder (FND) is a common and disabling neuropsychiatric condition, which disproportionally affects women compared with men. While the etiopathogenesis of this disorder remains elusive, immune dysregulation is emerging as one potential mechanism. To begin to understand the role of immune dysfunctions in FND, we assessed the prevalence of several common autoimmune diseases (ADs) in a large cohort of patients with FND and examined the influence of psychiatric comorbidities and biological sex.

Developing a Curriculum for Functional Neurological Disorder in Neurology Training: Questions and Answers.

Functional neurologic disorder (FND) is a common condition for which neurology residents often receive little to no formal teaching. Using a question-and-answer format, this article puts forward a case for why an FND curriculum is needed and aims to provide guidance on possible curricular content including medical knowledge, clinical skills, communication, and team-based collaboration. The authors also discuss methods for teaching and evaluating this knowledge and associated clinical skills, linking this to current Accreditation Council for Graduate Medical Education neurology milestones.

Dissociation in patients with epilepsy and functional seizures: A narrative review of the literature.

Dissociation is a "disruption of the usually integrated functions of consciousness, memory, identity or perception of the environment" according to DSM-5.  It is commonly seen in psychiatric disorders including primary dissociative disorders, post-traumatic stress disorder, depression, and panic disorder. Dissociative phenomena are also described in the context of substance intoxication, sleep deprivation and medical illnesses including traumatic brain injury, migraines, and epilepsy.

Inpatient Rehabilitation for Acute Presentations of Motor Functional Neurological Disorder: A Retrospective Cohort Study.

Objective: Patients with functional neurological disorder involving the motor system (eg, functional weakness, functional gait) may acutely present to the hospital for new-onset symptoms. For some, symptoms may remain severe enough at the time of hospital discharge to qualify for an inpatient rehabilitation facility stay.

Design: Data were extracted via retrospective chart review on functional neurological disorder patients ( N = 22) admitted to an inpatient rehabilitation facility between September 2019 and May 2022.

Development of a Definition of Postacute Sequelae of SARS-CoV-2 Infection.

Importance: SARS-CoV-2 infection is associated with persistent, relapsing, or new symptoms or other health effects occurring after acute infection, termed postacute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID. Characterizing PASC requires analysis of prospectively and uniformly collected data from diverse uninfected and infected individuals.

Objective: To develop a definition of PASC using self-reported symptoms and describe PASC frequencies across cohorts, vaccination status, and number of infections.

Neuropsychiatry's Role in the Postacute Sequelae of COVID-19: Report From the American Neuropsychiatric Association Committee on Research.

Postacute sequelae of COVID-19 can occur in patients who had only mild acute disease. A comprehensive neuropsychiatric approach reviews historical factors, provides objective assessment of symptoms, considers potential etiologies, and offers a therapeutic approach aimed at restoring premorbid functioning.

Development of an inpatient rehabilitation pathway for motor functional neurological disorders: Initial reflections.

Background: Emerging research supports a primary role for rehabilitation therapy alongside psychoeducation and psychotherapy in the treatment of functional neurological disorder (FND).

Objective: While consensus recommendations for physical therapists, occupational therapists, and speech and language pathologists treating FND have been published, specific recommendations for multidisciplinary FND care delivered on an inpatient rehabilitation unit are yet to be established.

Methods: This report describes one inpatient rehabilitation facility's efforts to design and implement a clinical pathway for patients with acute-onset motor FND-patients recently hospitalized for work-up of new neurological symptoms subsequently deemed functional.

Neurostimulation for the treatment of functional neurological disorder: A systematic review.

Functional Neurological Disorder (FND), also known as conversion disorder, is characterized by neurological symptoms that are incompatible with any known structural disorder and best explained by a biopsychosocial model. Evidence-based treatments for FND are limited, with cognitive behavioral therapy (CBT) and physiotherapy being the most effective interventions [1]. In recent years, functional neuroimaging studies have provided robust evidence of alterations in activity and connectivity in multiple brain networks in FND.

Sustained improvement with mindfulness-based therapy for psychogenic nonepileptic seizures.

Background: We previously reported on the efficacy of a manualized 12-session mindfulness-based therapy (MBT) for psychogenic nonepileptic seizures (PNES). Completion of MBT provided improvements in weekly PNES frequency and self-rated intensity.

Objectives: In this study, we aimed to determine sustainability of improvement of seizure-related measures at 3- to 6-month follow-up after treatment completion.

Functional neurological disorder: Engaging patients in treatment.

Patients with a functional neurological disorder can be difficult to engage in treatment. The reasons for this are complex and may be related to physician, patient and health care system issues. Providers contribute to difficulties in treatment engagement by giving confusing explanations for the patient symptoms, stigmatizing patients, and not allowing patients time to voice their questions and concerns.

The role of evidence-based guidelines in the diagnosis and treatment of functional neurological disorder.

Evidence-based clinical practice guidelines, based on systematic reviews of existing evidence, play an important role in improving and standardizing the quality of patient care in many medical and psychiatric disorders, and could play an important role in the diagnosis and treatment of functional seizures and other functional neurological disorder (FND) subtypes. There are several reasons to think that evidence-based guidelines might be especially beneficial for the management of FND. In particular, the interdisciplinary and multidisciplinary teamwork necessary for the care of people with FND, the current lack of formal clinical training in FND, and the rapidly expanding body of evidence relating to FND all make guidelines based on systematic literature reviews especially valuable.

A historical review of functional neurological disorder and comparison to contemporary models.

Over the centuries, various etiologies have been proposed to explain functional neurological disorders (FND), including functional seizures. These have included models relying on supernatural influences upon the body, emphasis on consequences of malfunctioning reproductive organs, the bodily expression of painful emotions involving traumatic memories, or cognitive distortions through attention and predictive biases. Many theorists, especially since the 19th century, have had overlapping themes that continue to be relevant in modern clinical use.

How to do things with words: Two seminars on the naming of functional (psychogenic, non-epileptic, dissociative, conversion, …) seizures.

Amongst the most important conditions in the differential diagnosis of epilepsy is the one that manifests as paroxysms of altered behaviour, awareness, sensation or sense of bodily control in ways that often resemble epileptic seizures, but without the abnormal excessive or synchronous electrical activity in the brain that defines these. Despite this importance, there remains little agreement - and frequent debate - on what to call this condition, known inter alia as psychogenic non-epileptic seizures (PNES), dissociative seizures (DS), functional seizures (FS), non-epileptic attack disorder (NEAD), pseudoseizures, conversion disorder with seizures, and by many other labels besides. This choice of terminology is not merely academic - it affects patients' response to and understanding of their diagnosis, and their ability to navigate health care systems.

Using evidence-based psychotherapy to tailor treatment for patients with functional neurological disorders.

Functional neurological disorder (FND) frequently presents with comorbid psychopathology (e.g., anxiety, depressive, post-traumatic stress disorders (PTSD), somatic symptom and pain syndromes, and dissociative and personality disorders).

Is sexual trauma a risk factor for functional (psychogenic) seizures?

The relationship between functional seizures (FS) and sexual trauma has received attention in many previous studies. However, the mechanisms underlying this relationship have not been elucidated yet. The purpose of this narrative review is to explore and speculate on the underpinning neurobiological mechanisms for the association and link between sexual trauma and functional seizures.

Functional Neurologic Disorders: The Need for a Model of Care.

Neurologists are commonly consulted for patients with a functional neurologic disorder. Best practices as to their diagnosis and treatment have been established, and multiple academic centers have programs in place for their treatment. However, given the number of patients suffering from this condition, a comprehensive model of care that can be broadly implemented needs to be developed and applied beyond specialized academic programs.

Evidence-Based Practice for the Clinical Assessment of Psychogenic Nonepileptic Seizures: A Report From the American Neuropsychiatric Association Committee on Research.

The American Neuropsychiatric Association's Committee on Research assigned the task of defining the most helpful clinical factors and tests in establishing the diagnosis of psychogenic nonepileptic seizures (PNES) during a neuropsychiatric assessment. A systematic review of the literature was conducted using three search engines and specified search terms for PNES and the predetermined clinical factors and diagnostic tests, followed by a selection process with specific criteria. Data extraction results from selected articles are presented for clinical factors (semiology, psychiatric comorbidities, medical comorbidities, psychological traits) and diagnostic tests (EEG, psychometric and neuropsychological measures, prolactin level, clinical neuroimaging, autonomic testing).
