Ictal speech and language dysfunction in adult epilepsy: Clinical study of 95 seizures.

PURPOSE: To analyze the semiological characteristics of the language and speech disorders arising during epileptic seizures, and to describe the patterns of language and speech disorders that can predict laterality of the epileptic focus. METHOD: This study retrospectively analyzed 95 consecutive videos of seizures with language and/or speech disorders in 44 patients admitted for diagnostic video-EEG monitoring. Laterality of the epileptic focus was defined according to electro-clinical correlation studies and structural and functional neuroimaging findings. Language and speech disorders were analyzed by a neurologist and a speech therapist blinded to these data. RESULTS: Language and/or speech disorders were subdivided into eight dynamic patterns: pure anterior aphasia; anterior aphasia and vocal; anterior aphasia and "arthria"; pure posterior aphasia; posterior aphasia and vocal; pure vocal; vocal and arthria; and pure arthria. The epileptic focus was in the left hemisphere in more than 4/5 of seizures presenting with pure anterior aphasia or pure posterior aphasia patterns, while discharges originated in the right hemisphere in almost 2/3 of seizures presenting with a pure vocal pattern. No laterality value was found for the other patterns. CONCLUSION: Classification of the language and speech disorders arising during epileptic seizures into dynamic patterns may be useful for the optimal analysis of anatomo-electro-clinical correlations. In addition, our research has led to the development of standardized tests for analyses of language and speech disorders arising during seizures that can be conducted during video-EEG sessions.

Hypnosis and movement disorders: State of the art and perspectives.

INTRODUCTION: Hypnosis might represent an interesting complementary therapeutic approach to movement disorders, as it takes into account not only symptoms, but also well-being, and empowers patients to take a more active role in their treatment. METHODS: Our review of the literature on the use of hypnosis to treat movement disorders was done by systematically searching the PubMed database for reports published between 1984 and November 2015. The following variables were extracted from each selected paper: study design; sample size; type of movement disorder; hypnotic procedure; treatment duration; and efficacy. RESULTS: Thirteen papers were selected for detailed analysis. Most concerned tremor in Parkinson's disease and tics in Gilles de la Tourette syndrome. Although promising, the data were insufficient to allow conclusions to be drawn on the efficacy of hypnosis in movement disorders or to recommend its use in this setting. CONCLUSION: Well-designed studies taking into account some specific methodological challenges are needed to determine the possible therapeutic utility of hypnosis in movement disorders. In addition to the potential benefits for such patients, hypnosis might also be useful for studying the neuroanatomical and functional underpinnings of normal and abnormal movements.

'The Move', an innovative simulation-based medical education program using roleplay to teach neurological semiology: Students' and teachers' perceptions.

INTRODUCTION: Neurological disorders are frequently being managed by general practitioners. It is therefore critical that future physicians become comfortable with neurological examination and physical diagnosis. Graduating medical students often consider neurological examination as one of the clinical skills they are least comfortable with, and they even tend to be neurophobic. One way to improve the learning of neurological semiology is to design innovative learner-friendly educational methods, including simulation training. METHODS: The feasibility of mime-based roleplaying was tested by a simulation training program in neurological semiology called 'The Move'. The program was proposed to third-year medical students at Pierre and Marie Curie University in Paris during their neurology rotation. Students were trained to roleplay patients by miming various neurological syndromes (pyramidal, vestibular, cerebellar, parkinsonian) as well as distal axonopathy, chorea and tonic-clonic seizures. Using an anonymous self-administered questionnaire, the students' and teachers' emotional experience and views on the impact of the program were then investigated. RESULTS: A total of 223/365 students (61%) chose to participate in the study. Both students and teachers felt their participation was pleasant. Students stated that The Move increased their motivation to learn neurological semiology (78%), and improved both their understanding of the subject (77%) and their long-term memorization of the teaching content (86%). Although only a minority thought The Move was likely to improve their performance on their final medical examination (32%), a clear majority (77%) thought it would be useful for their future clinical practice. Both students (87%) and teachers (95%) thought The Move should be included in the medical curriculum. CONCLUSION: Mime-based roleplaying simulation may be a valuable tool for training medical students in neurological semiology, and may also help them to overcome neurophobia.

Thrombolysis in Stroke Patients with Isolated Aphasia.

BACKGROUND: Data about evolution of aphasia following stroke are rare and controversial especially following fibrinolysis. The aim of this study was to describe the early clinical patterns of isolated aphasia in consecutive stroke patients with or without thrombolysis. METHODS: Clinical and radiological data of consecutive stroke patients were routinely entered in prospective registry. Patients were considered aphasic when NIHSS (National Institutes of Health Stroke Scale) item 9 >0. 'Isolated aphasia' was defined by aphasic patients without motor limb deficit. We created a 'composite language score' obtained by summing the NIHSS items 1b, 1c and 9, which reflects language-processing ability. Recovery of functions was evaluated as measured by global NIHSS, composite language score and language screening test (LAST) at baseline, H24 and day 7 (D7). 'Mild deficit' was defined as global NIHSS <5. RESULTS: A total of 100 consecutive patients met study criteria for isolated aphasia. Twenty-five underwent thrombolysis and 75 did not. There was no difference between the 2 groups concerning demographic characteristics, involved territories and presence of arterial occlusion, initial median NIHSS, composite language and LAST scores at entrance. Evolution was significantly better in thrombolysed patient for the 3 testings: NIHSS, composite language score and LAST at D7 (respective p = 0.0002; p = 0.01 and p = 0.004). Similar results were found when we focused on the subgroups of patients with initial 'mild' deficits (p = 0.01; p = 0.0003 and p = 0.007). No symptomatic hemorrhagic transformation occurred following thrombolysis. CONCLUSION: These data strongly suggest that thrombolysis is safe and effective in patients with 'isolated aphasia,' even if the global NIHSS score is <5.

[LAST-Q: Adaptation and normalisation in Quebec of the Language Screening Test]. / LAST-Q: adaptation et normalisation franco-québécoises du Language Screening Test.

The goal of the present study was to adapt and to establish normative data for the recently developed Language Screening Test (LAST; Flamand-Roze et al., 2011) in the French-Canadian population according to age and level of education. After an adaptation process, 100 French-Canadian speakers were evaluated with the LAST-Q. As expected, a perfect score of 15/15 was obtained for all high level education participants, and a score of 14/15 was obtained for all participants with a lowest level of education or aged 80 years or more. Thanks to this adaptation, LAST-Q can be used in acute patients in stroke unit in Quebec.

[Language and swallowing disorders in acute stroke patients: tools and early management]. / Troubles du langage et de la déglutition à la phase aiguë des accidents vasculaires cérébraux : outils d'évaluation et intérêt d'une prise en charge précoce.

INTRODUCTION: The contribution of stroke units to improve morbidity, mortality and recovery in stroke victims is clearly demonstrated. However, acute management of language disorders in these specialized units is controversial and little standardization is seen for the management of swallowing disorders. STATE OF THE ART: The recently validated French scale for rapid screening for language disorders (LAST) in acute stroke patients should enable optimal detection and early management. A standardized protocol should be used to screen for and manage swallowing disorders. This protocol should include daily evaluations, individually tailored rehabilitation sessions, adaptation of food textures, patient education for adequate eating position, team training, and information for families. PERSPECTIVES AND CONCLUSIONS: These protocols imply co-operation and coordination between the medical and allied profession teams and the daily presence of a speech and language therapist. This presence is crucial for patients in stroke units to achieve the full benefits of the management scheme proposed in this paper.

Aphasia in border-zone infarcts has a specific initial pattern and good long-term prognosis.

BACKGROUND: While border-zone infarcts (BZI) account for about 10% of strokes, studies on related aphasia are infrequent. The aim of this work was to redefine specifically their early clinical pattern and evolution. METHODS: We prospectively studied consecutive patients referred to our stroke unit within a 2-year period. Cases of aphasia in right-handed patients associated with a MRI confirmed left-sided hemispheric BZI were included. These patients had a standardized language examination in the first 48 h, at discharge from stroke unit and between 6 and 18 months later. RESULTS: Eight patients were included. Three had anterior (MCA/ACA), two posterior (MCA/PCA), two both anterior and posterior, and one bilateral BZI. All our patients initially presented transcortical mixed aphasia, characterized by comprehension and naming difficulties associated with preserved repetition. In all patients, aphasia rapidly improved. It fully recovered within a few days in three patients. Initial improvement was marked, although incomplete in the five remaining patients: their aphasias specifically evolved according to the stroke location toward transcortical motor aphasia for the three patients with anterior BZI and transcortical sensory aphasia for the two patients with posterior BZI. All patients made a full language recovery within 18 months after stroke. CONCLUSIONS: We report a specific aphasic pattern associated with hemispheric BZI, including an excellent long-term outcome. These findings appear relevant to (i) clinically suspect BZI and (ii) plan rehabilitation and inform the patient and his family of likelihood of full language recovery.
