Using evidence-based psychotherapy to tailor treatment for patients with functional neurological disorders
Full text linkFunctional 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). It can become chronic and lead to unemployment and disability for many patients. Psychosocial factors play an important role in the onset and perpetuation of symptoms. Consequently, psychotherapy is recommended for the treatment of FND in general, and especially for the single symptom-based subtype of functional seizures (FS). Some of the psychotherapy approaches that have been utilized for FND include cognitive-behavioral therapy (CBT), third wave approaches, and psychodynamic psychotherapies as well as group therapeutic and psychoeducational interventions. For patients with FS and PTSD, prolonged exposure therapy, a CBT-based treatment has been implemented. The purpose of this manuscript is to describe and analyze specific elements (e.g., theoretical foundations, tools, targets, definitions of success) of the main psychotherapeutic approaches used in patients with FND. Our premise is that these modalities will overlap considerably in some respects. We will conclude by discussing how discrete differences may render them more suitable for subgroups of patients with FND or for patients at different timepoints of their recovery process.Fil: Myers, Lorna.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Psychogenic nonepileptic seizures: a treatment review. What have we learned since the beginning of the millennium?
Full text linkGaston BasletDepartment of Psychiatry, Brigham and Women’s Hospital, Harvard Medical School, Boston, MA, USAAbstract: Psychogenic nonepileptic seizures (PNES) can significantly affect an individual’s quality of life, the health care system, and even society. The first decade of the new millennium has seen renewed interest in this condition, but etiological understanding and evidence-based treatment availability remain limited. After the diagnosis of PNES is established, the first therapeutic step includes a presentation of the diagnosis that facilitates engagement in treatment. The purpose of this review is to present the current evidence of treatments for PNES published since the year 2000 and to discuss further needs for clinical treatment implementation and research. This article reviews clinical trials that have evaluated the efficacy of structured, standardized psychotherapeutic and psychopharmacological interventions. The primary outcome measure in clinical trials for PNES is event frequency, although it is questionable whether this is the most accurate indicator of functional recovery. Cognitive behavioral therapy has evidence of efficacy, including one pilot randomized, controlled trial where cognitive behavioral therapy was compared with standard medical care. The antidepressant sertraline did not show a significant difference in event frequency change when compared to placebo in a pilot randomized, double-blind, controlled trial, but it did show a significant pre- versus posttreatment decrease in the active arm. Other interventions that have shown efficacy in uncontrolled trials include augmented psychodynamic interpersonal psychotherapy, group psychodynamic psychotherapy, group psychoeducation, and the antidepressant venlafaxine. Larger clinical trials of these promising treatments are necessary, while other psychotherapeutic interventions such as hypnotherapy, mindfulness-based therapies, and eye movement desensitization and reprocessing may deserve exploration. Flexible delivery of treatment that considers the heterogeneous backgrounds of patients is emphasized as necessary for successful outcomes in clinical practice.Keywords: conversion disorder, therapeutics, clinical trials, psychotherapeutic interventions, psychopharmacological intervention
Psychogenic non-epileptic seizures: A model of their pathogenic mechanism
No full textAbstractPsychogenic non-epileptic seizures (PNES) consist of paroxystic events facilitated by a dysfunction in emotion processing. Models explaining the pathogenic mechanisms leading to these seizure-like episodes are limited. In this article, evidence that supports dysfunction at the level of arousal tolerance, cognitive-emotional information processing and volitional control is reviewed. A hypothetical pathophysiological mechanism is discussed based on functional neuroimaging evidence from PNES-related conditions and traits. This pathophysiological model suggests an alteration in the influence and connection of brain areas involved in emotion processing onto other brain areas responsible for sensorimotor and cognitive processes. Integrating this information, PNES are conceptualized as brief episodes facilitated by an unstable cognitive-emotional attention system. During the episodes, sensorimotor and cognitive processes are modified or not properly integrated, allowing the deployment of autonomous prewired behavioral tendencies. Finally, I elaborate on how therapeutic applications could be modified based on the proposed hypothetical model, potentially improving clinical outcomes
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Neuropsychiatry's Role in the Postacute Sequelae of COVID-19: Report From the American Neuropsychiatric Association Committee on Research.
No full textThe postacute sequelae of COVID-19 infection (PASC), also known as post-COVID condition or "long COVID," refers to symptoms that persist after the initial acute phase of the infection. PASC symptoms may occur in patients who had mild acute disease. On the basis of current data, commonly reported neurological and psychiatric symptoms in PASC include sleep problems, fatigue, cognitive impairment, headache, sensorimotor symptoms, dizziness, anxiety, irritability, and depression. Knowledge from neuropsychiatric sequelae of other viral infections, such as other coronaviruses, provides us with information about the heterogeneity and similarities of neuropsychiatric clinical presentations that may follow viral illnesses over a long period. Several, possibly overlapping, pathophysiological mechanisms have been proposed to explain neuropsychiatric PASC: direct effects of the virus and immunological, vascular, functional, iatrogenic, and other etiologies. The authors present practice considerations for clinicians confronted with the challenge of evaluating and treating patients who have neuropsychiatric PASC. A comprehensive neuropsychiatric approach reviews historical factors, provides an objective assessment of symptoms, carefully considers all potential etiologies, and offers a therapeutic approach aimed at restoring premorbid functioning. Given the currently limited therapeutic options for neuropsychiatric PASC, unless an alternative etiology is identified, treatment should be symptom based and guided by evidence as it emerges
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
