A Falls Prevention Program for People After Stroke in Guyana: An International Collaboration.

OBJECTIVE: The objective was to describe the social, environmental, and cultural adaptations to an existing falls program and assess acceptability and preliminary effectiveness of the program in reducing fear, reducing falls, and improving function among individuals poststroke in Guyana. METHODS: A quasi-experimental pilot study with a pretest/ posttest in-group design was developed through a collaboration of researchers in Guyana and the US. Participants took part in the falls prevention program for 8 weeks. Outcome measures included a 10-meter walk test, Five Times Sit to Stand, and subjective questionnaires for falls incidence and balance confidence at the beginning and end. RESULTS: Twenty participants completed the study. One participant experienced medical complications and their data were excluded from analysis. Fifteen participants (78.9%) demonstrated improvements in comfortable and fast walking speed. Twelve participants completed the Five Times Sit to Stand Test. Eleven (91.67%) improved their time at posttest, with 9 (81.8%) demonstrating a clinically important improvement. Nineteen participants had sustained at least 1 fall prior to the study. Only 1 participant reported a fall during the program. Initially, the majority of participants (11/19) were very concerned about falling. At the end, only 1 was very concerned about falling, and the majority (15/19) were not concerned at all. Post-test surveys of participants indicated acceptability of the program. CONCLUSIONS: This pilot program helped reduce fall risk and improve confidence, gait speed and community mobility of the study participants. Future research at other rehabilitation departments in Guyana would help increase generalizability of the program. IMPACT STATEMENT: The program can be used clinically by physical therapists in Guyana both in departments and as a home program. Shared knowledge and experience of researchers considering research evidence and the environmental, social, and economic conditions of people living in Guyana were important in developing an effective program.

Peripheral electrical stimulation on neuroplasticity and motor function in stroke patients: a systematic review and meta-analysis.

INTRODUCTION: The use of electrotherapy has been presented as a great resource for the professional physiotherapist in the most diverse pathologies. Stroke is a neurological condition responsible for sequelae such as hemiplegia that directly impair the quality of life of patients. OBJECTIVE: This study aimed to review the literature on the effects of electrotherapeutic resources on motor function and neuroplasticity in individuals with post-stroke sequelae. MATERIALS AND METHODS: 2427 articles were found in databases according to search criteria for each base according to the included descriptors (EndNote Web). After exclusion of duplicate articles, automatically and manually, Phase 1 was performed - reading of titles and abstracts of 1626 articles according to eligibility criteria by two blinded reviewers using the programme Rayyan QCRI (Qatar Computing Research Institute), conflicts were resolved in consensus between the two reviewers. Thus, 13 articles were selected for Phase 2-13 articles were selected for reading in full, leaving 8 articles in this review. To assess the quality of bias of the selected studies, the PEDro Scale was used. RESULTS: In the assessment of neuroplasticity, statistically significant results were found in two studies (p < 0.05). However, the effects of electrostimulation stood out significantly in the motor function of these individuals (p < 0.05). It can be considered with neuroplasticity, since improved functionality can be related to electrostimulation-induced neuroplasticity. Conclusions Electrostimulation is able to promote neuroplasticity and increase motor function, generating positive effects in the treatment of individuals with post-stroke sequelae.

Multimodal physical training combined with tDCS improves physical fitness components in people after stroke: a double-blind randomized controlled trial.

BACKGROUND: Transcranial direct current stimulation (tDCS) seems to be a potential tool to optimize the long-term effects of multimodal physical training (MPT) on fitness components in post-stroke patients. OBJECTIVE: We investigated the effects of cortical tDCS combined with MPT on motor function reflected by strength, motor performance, and cardiorespiratory capacity in chronic stroke patients. METHODS: This double-blind randomized controlled trial included 18 volunteers (55 ± 10 y, 72 ± 13 kg), who underwent MPT preceded by either sham stimulation (SHAM) or 2 mA bi-hemispheric tDCS. MPT consisted of 24 sessions of 60-70 min performed 2 d/wk within 12-16 weeks, with individualized intensity. Outcomes were Fugl-Meyer scores for lower limbs (FM-LL), and total (FM-Total); speed in the 10-m walk test (10MWT); oxygen uptake and work output at maximal effort (VO2max and Wmax), and gas exchange threshold (VO2-GET and W-GET); peak torque of isokinetic knee extension (PT-EXT) and flexion (PT-FLEX) of paretic and non-paretic limbs; bilateral strength deficit during knee extension (DS-EXT) and flexion (DS-FLEX). RESULTS: Pre- vs. post-intervention improvements were detected in tDCS vs. SHAM (p < 0.05) for FM-total (29.6% vs. 15.9%; effect size [ES] = 0.78), FM-LL (35.9% vs. 9.0%; ES = 1.23), 10MWT (10.6% vs. 3.8%; ES = 0.67), Wmax (75.0% vs. 4.3%; ES = 1.68), W-GET (91.6% vs. 12.4%; ES = 1.62), PT-EXT (25.6% vs. -6.5%; ES = 1.94) and PT-FLEX (26.3% vs. 9.8%; ES = 0.65) of the paretic limb, and DS-EXT (-13.7% vs. 2.5; ES = 1.43). CONCLUSION: Bi-hemispheric cortical tDCS optimized the effects of MPT performed with moderate volume and intensity upon muscle strength, motor function, and cardiorespiratory performance in stroke hemiparetic survivors.

Body structure/function impairments and activity limitations of post-stroke that predict social participation: a systematic review.

BACKGROUND: Stroke is the leading cause of death and disability in Brazil, and its prognostic indicators of social reintegration are not well established yet. OBJECTIVE: To identify body structure/function impairments and activity limitations in post-stroke that predict social participation restrictions in the community. METHODS: cohort studies were selected, involving adult post-stroke participants, which investigated body structure and function impairments or activity limitations of post-stroke individuals as predictors of social participation in the community. Studies that included individuals with subarachnoid hemorrhage, other neurological disorders and participants in long-term care facilities were excluded. The Newcastle-Ottawa quality assessment scale was applied to assess the methodological quality. The results were synthesized according to the found exposures, considering the used statistical models. RESULTS: Eleven articles were included, with a total of 2,412 individuals, 58.4% men, 83.7% ischemic stroke. Seven exposures were assessed across studies, in which 10 studies assessed body structure and function exposures (stroke severity, cognitive, executive, emotional and motor function), and 8 studies assessed activity exposures (daily living activity and walking ability). CONCLUSION: There is some evidence that stroke severity, mental and motor deficits, limitations in activities of daily living and the ability to walk after a stroke can predict social participation in the community.

The ontogenetic model for CVA rehabilitation with transcranial stimulation

Currently, transcranial stimulation for CVA treatment is based on the interhemispheric rivalry model. This model has proven to have many anomalies, necessitating a new paradigm. Spontaneous recovery from post-CVA hemiplegia has an ontogenetic pattern. We reanalyzed the 2008 longitudinal London study and found that cortical disinhibition is the mechanism for ontogenetic CVA recovery. We propose that transcranial stimulation with 10 Hz rTMS or anode electrical microstimulation can produce CVA recovery similar to spontaneous recovery. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2466).

Actualmente la aplicación de la estimulación transcraneal para el tratamiento del ACV se realiza con base en el modelo de rivalidad interhemisférica. Este modelo ha mostrado muchas anomalías que hacen necesario un nuevo paradigma. La recuperación espontánea de la hemiplejia post-ACV tiene patrón ontogénico. Reanalizamos el estudio longitudinal de Londres 2008 y encontramos que su propuesta corresponde al mecanismo de recuperación ontogénica del ACV. Planteamos que la estimulación transcraneal, utilizando EMTr a 10 Hz o microestimulación eléctrica anódica, podría recuperar el ACV de manera similar a la recuperación espontánea.

Validity evidence for the Cognitive Screening test in stroke patients / Evidências de validade para o instrumento Triagem Cognitiva em pacientes com acidente vascular cerebral / Evidencias de validez del instrumento de Cribado de Deterioro Cognitivo en pacientes con accidente cerebrovascular

Cognitive deficits are common among post-stroke patients. Cognitive impairments of this sort are mediated by age and education. In Brazil, the only specific cognitive screening tool designed for post-stroke patients is the Cognitive Screening Test (Triagem Cognitiva - TRIACOG). The goal of this study was to investigate validity evidence related to external variables for the TRIACOG. Our sample included 153 adults and elderly people (M = 60.08, SD = 9.61) from Porto Alegre and metropolitan area, comprising 87 post-stroke patients and 66 healthy individuals. Three-way ANOVAs were used to assess main effects and interactions between the variables group (clinical/control), age and education. An influence of group and age on scores in the TRIACOG was found. We emphasize the relevance of these results to the selection of cut-off points for the tasks and cognitive functions assessed by the instrument, considering education and age, so as to allow more accurate identification of deficits in post-stroke patients.

Simultaneous thromboses in patients with SARS-CoV-2 infection

COVID-19 infection has a high morbidity and mortality rate. Although there is mainly pulmonary involvement, SARS-CoV-2 infection is considered to be a true endothelial disease, given these patients' increased risk of developing both arterial and venous thrombotic phenomena. We present three cases of patients with active SARS-CoV-2 infection and simultaneous thromboses in different vascular territories: cerebrovascular disease and pulmonary embolism, cerebrovascular disease and peripheral arterial embolism, and cerebrovascular disease plus deep vein thrombosis. We emphasize the scant evidence on the topic in the current literature and the importance of being alert to the onset of these events during the clinical course of patients with acute infection with the new coronavirus. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2347).

La infección por COVID-19 tiene una alta tasa de morbimortalidad, si bien existe principalmente compromiso pulmonar, se considera que la infección por SARS-CoV-2 es una verdadera endoteliopatía, dado el riesgo aumentado que tienen estos pacientes de desarrollar fenómenos trombóticos como arteriales y venosos. Presentamos tres casos de pacientes con infección activa por SARS-CoV-2 y trombosis simultáneas en diferentes territorios vasculares: enfermedad cerebrovascular y embolismo pulmonar, enfermedad cerebrovascular y embolismo arterial periférico, enfermedad cerebrovascular más trombosis venosa profunda. Enfatizamos en la poca evidencia de la literatura actual al respecto y la importancia de estar atentos al desarrollo de estos eventos durante la evolución de los pacientes con infección aguda por nuevo coronavirus.

Awareness towards stroke among high school students in Brazil: a cross-sectional study

ABSTRACT BACKGROUND: Stroke is one of the main causes of death worldwide. Educational interventions on stroke are potentially effective in reducing the period between the onset of symptoms and the initial emergency medical assistance. OBJECTIVES: To assess high school students' knowledge of stroke. DESIGN AND SETTING: Cross-sectional study conducted in high schools in northeastern Brazil. METHODS: A self-structured questionnaire survey regarding stroke awareness was applied among high school students in northeastern Brazil. Data were collected between 2018 and 2019. The chi-square test and other descriptive statistics were used. Univariate and multivariate analyses were performed using logistic regression. RESULTS: A total of 1,788 students were analyzed. Eighty percent (n = 1430) of them did not have the minimum knowledge on how to act in a stroke situation. Only 10% (n = 179) presented the ideal knowledge on how to act. Males presented lower levels of knowledge on risk factors (odds ratio, OR: 0.62%; 95% confidence interval, CI: 0.49-0.79) and signs and symptoms of stroke (OR: 0.63%; 95% CI: 0.52-0.77). Students with ≥ 10 years of schooling (OR: 1.64%; 95% CI: 1.30-2.07) demonstrated greater knowledge of signs and symptoms of stroke. Students aged 18 years (OR: 1.70%; 95% CI: 1.14-2.52) demonstrated greater knowledge than other ages regarding the telephone number of the emergency medical services. CONCLUSIONS: There was a knowledge deficit with regard to recognizing stroke and activating the emergency medical services. The findings apply to the sample investigated and suggest that there is a need for stroke educational interventions, starting in high school.

Efectos del Ejercicio Físico Aeróbico sobre los Factores de Riesgo Modificables que Predisponen a un Segundo Evento de Accidente Cerebrovascular. Revisión Sistemática / Effects of Aerobic Physical Exercise on Modifiable Risk Factors that Predispose to a Second Stroke Event. Systematic review

Introducción. El accidente cerebrovascular (ACV) es una condición de salud que ha aumentado su prevalencia en los últimos años, la cual se encuentra intrínsecamente asociada a la presencia de enfermedades crónicas no transmisibles (ECNT), como lo son la diabetes mellitus, dislipidemia e hipertensión, las que, de no ser controladas tras la instauración del primer episodio, predisponen a la afección de un segundo evento de ACV. Es sabido que el ejercicio físico aeróbico juega un rol fundamental en el control de las ECNT, junto con otros factores, como lo son los cambios de hábitos y adherencia a los tratamientos farmacológicos. Objetivo. Analizar los efectos que tiene el ejercicio físico aeróbico en población secuelada de un ACV sobre las ECNT que predisponen a sufrir un segundo evento cerebrovascular. Método. Se realizó una exhaustiva búsqueda en las bases de datos EBSCO, Scielo, PubMed y PEdro, utilizando las palabras claves "stroke and modifiable risk factors and aerobic physical exercise"; obteniendo un total de 56438 artículos. Para la selección, se consideraron los siguientes criterios de inclusión: pacientes entre 45 y 65 años con secuelas de ACV de más de 6 meses, que analizaran el efecto del ejercicio físico sobre las ECNT tras un evento cerebrovascular. Resultados. Se seleccionaron tres artículos científicos tipo ensayo clínico aleatorizados controlados, los cuales analizan los efectos que produce el ejercicio físico aeróbico sobre las ECNT tras un ACV. Entre los resultados con mayor significancia estadística (P entre 0.01 y 0.05) se encuentra el aumento en el consumo peak de oxígeno y el aumento en el colesterol HDL. Conclusiones. Es indispensable sistematizar la información de los programas de rehabilitación neurológica, que permitan levantar datos de las intervenciones, y así poder potenciar el ejercicio físico aeróbico de forma segura para poder controlar las ECNT subyacentes y así prevenir futuros eventos cerebrovasculares.

Background. Cerebrovascular accident (CVA) is a health condition that has suspected its prevalence in recent years, which is intrinsically associated with the presence of chronic non-communicable diseases (CNCD), such as diabetes mellitus, dyslipidemia and hypertension, which, if not controlled after the establishment of the first episode, predispose to the condition of a second stroke event. It is known that aerobic physical exercise plays a fundamental role in the control of NCDs, along with other factors, such as changes in habits and adherence to pharmacological treatments. Objective. To analyze the effects of aerobic physical exercise in the population after a stroke on NCDs that predispose to a second cerebrovascular event. Method. An exhaustive search was carried out in the EBSCO, Scielo, PubMed and PEdro databases, using the keywords "stroke and modifiable risk factors and aerobic physical exercise"; obtaining a total of 56438 articles. For selection, consider the following inclusion criteria: patients between 45 and 65 years of age, stroke sequelae of more than 6 months, who will analyze the effect of physical exercise on NCDs after a cerebrovascular event. Results. Three controlled randomized clinical trial were selected, which analyze the effects produced by aerobic physical exercise on NCDs after a stroke. Among the results with the highest statistical significance (P between 0.01 and 0.05) is the increase in peak oxygen consumption and the increase in HDL cholesterol. Conclusion. It is essential to systematize the information on neurological rehabilitation programs, to collect data from the interventions, and thus be able to promote aerobic physical exercise safely to control the underlying NCDs and thus prevent future cerebrovascular events.

Serum activity of matrix metalloproteinase-2 and -9 is increased in chronic post-stroke individuals: a cross-sectional exploratory study.

BACKGROUND: High concentrations of matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) are associated with inflammation early after stroke. In chronic stages, the elevation of some cytokines is related to the presence of co-morbid conditions in these individuals. In addition to this, some characteristics such as sensorimotor impairment, atrophy, and sedentary lifestyle predispose the system to an inflammatory response. OBJECTIVE: To quantify MMP-2 and -9 serum activity in chronic post-stroke individuals and correlate it with variables of physical activity level, body composition, functional and walking capacity, and with inflammatory biomarkers. Additionally, gelatinase activity was characterized according to motor impairment. METHODS: Fourteen patients with stroke onset >6 months and seven healthy individuals were enrolled in this study. The clinical assessment included: body composition, measure by bioelectrical impedance analyzer; Fugl-Meyer Motor Assessment Scale; six-minute and ten-meter walk tests, and physical activity level assessed by the StepWatch® Activity Monitor. Blood samples were collected from antecubital vein and serum MMP-2 and -9 activity was analyzed using gelatin Zymography, and the TNFα, IL-6, IL-1ß, IL-10 biomarkers using ELISA kits. RESULTS: Chronic post-stroke individuals presented an increased activity of MMP-2 and -9 compared to healthy individuals. Positive correlations with time and steps in low cadence and negative ones with medium cadence and peak activity index were observed. According to the motor impairment, the MMP-2 activity was increased in the mild-moderate group compared to the control group. CONCLUSION: Increased gelatinases in chronic post-stroke individuals could describe an inflammation process related to the limited capacity of walking in high intensities.

Methods: cross-sectional study, carried out with 160 cerebrovascular accident survivors. Data were collected using the Barthel Index, Cerebrovascular Accident Specific Quality of Life Scale, and semi-structured instruments for sociodemographic and clinical data, analyzed by descriptive and inferential statistics. Results: health-related quality of life was associated with work activity (p=0.027), physical activity (p=0.007), functional capacity (p=0.001), presence of caregiver (<0.001), motor alteration (p = 0.001) and rehabilitation (p=0.003). The functionally dependent people were 14.61 times more likely to present low health-related quality of life, and those with motor impairment were 3.07 times more likely. Conclusions: it was evidenced that functional dependence and motor impairment increase the chance of low health-related quality of life in cerebrovascular accident survivors.

Repetitive Peripheral Sensory Stimulation as an Add-On Intervention for Upper Limb Rehabilitation in Stroke: A Randomized Trial.

INTRODUCTION: Repetitive peripheral sensory stimulation (RPSS) followed by 4-hour task-specific training (TST) improves upper limb motor function in subjects with stroke who experience moderate to severe motor upper limb impairments. Here, we compared effects of RPSS vs sham followed by a shorter duration of training in subjects with moderate to severe motor impairments in the chronic phase after stroke. METHODS: This single-center, randomized, placebo-controlled, parallel-group clinical trial compared effects of 18 sessions of either 1.5 h of active RPSS or sham followed by a supervised session that included 45 min of TST of the paretic upper limb. In both groups, subjects were instructed to perform functional tasks at home, without supervision. The primary outcome measure was the Wolf Motor Function Test (WMFT) after 6 weeks of treatment. Grasp and pinch strength were secondary outcomes. RESULTS: In intention-to-treat analysis, WMFT improved significantly in both active and sham groups at 3 and 6 weeks of treatment. Grasp strength improved significantly in the active, but not in the sham group, at 3 and 6 weeks. Pinch strength improved significantly in both groups at 3 weeks, and only in the active group at 6 weeks. CONCLUSIONS: The between-group difference in changes in WMFT was not statistically significant. Despite the short duration of supervised treatment, WMFT improved significantly in subjects treated with RPSS or sham. These findings are relevant to settings that impose constraints in duration of direct contact between therapists and patients. In addition, RPSS led to significant gains in hand strength.Trial Registry Name: Peripheral Nerve Stimulation and Motor Training in Stroke Clinical Trials.gov identifier: NCT0265878 https://clinicaltrials.gov/ct2/show/NCT02658578.

Factores de riesgo para enfermedad cerebrovascular en el adulto mayor / Risk Factors for Cerebrovascular Disease in the Older Adult

Introducción: La vejez está subvalorada, poco se piensa en el bienestar físico y psicosocial del anciano. La enfermedad cerebrovascular tiene como factores de riesgo comorbilidades como la hipertensión arterial, la diabetes mellitus, la dislipidemia, cardiopatías o malos estilos de vida como el consumo de cigarrillo, la obesidad y la poca actividad física, todos estos comunes en esta etapa de la vida. Objetivo: Identificar los factores de riesgo que presentan los adultos mayores para sufrir enfermedad cerebrovascular de un centro gerontológico de la ciudad de Medellín. Métodos: Fue una investigación descriptiva, de tipo transversal; se indagaron 37 adultos mayores con historias clínicas y exámenes de laboratorio. Se midieron los niveles de hemoglobina glicosilada, colesterol total, colesterol de baja densidad, colesterol de alta densidad y triglicéridos. Resultados: Se evidenció que la población era en su mayoría de sexo masculino con 51,4 por ciento y el sexo femenino con 48,6 por ciento; con rango de edad entre 60 y 70 años el 51,4 por ciento. Los factores de riesgo más relevantes fueron el índice de masa corporal mayor o igual a 25 con (75,7 por ciento), hipertensión arterial y no realizar actividad física. Conclusiones: Se logró determinar los principales factores de riesgo que tienen estos adultos mayores para sufrir enfermedad cerebrovascular; con resultados algunos similares y otros diferentes a estudios a nivel mundial. Con actividades de promoción y prevención se pueden intervenir estilos de vida de la población(AU)

Introduction: Old age is undervalued; little is thought about the physical and psychosocial well-being of the elderly. Among the risk factors of cerebrovascular disease, there are comorbidities, such as high blood pressure, diabetes mellitus, dyslipidemia and cardiopathies, or poor lifestyles like cigarette smoking, obesity and little physical activity, all of which are common at this stage of life. Objective: To identify, in a gerontological center in Medellín City, the risk factors that older adults present for being affected by cerebrovascular disease. Methods: This was a descriptive and cross-sectional research carried out with 37 older adults with medical antecedents and laboratory tests. The levels of glycated hemoglobin, total cholesterol, low-density and high-density cholesterol, as well as triglycerides were measured. Results: It was evidenced that the population was mostly male (51.4 por ciento), while females accounted for 48.6 por ciento. Their age range was mostly between 60 and 70 years (51.4 por ciento). The most relevant risk factors were body mass index greater than or equal to 25 (75.7 por ciento), arterial hypertension and not doing any physical activity. Conclusions: It was possible to determine the main risk factors for these older adults being affected by cerebrovascular disease; in this respect, some results were similar to and others were different from studies worldwide. With promotion and prevention activities, lifestyles of the population can be intervened(AU)

El nivel de significación se halló según p valor ≤ 0,05 a través de Chi cuadrado de independencia. Resultados: La mortalidad proporcional predominó en el accidente cerebrovascular hemorrágico tipo hemorragia intracraneal no traumática (p= 0,118), ausencia de reflejos del tallo encefálico (p=0,000), anisocoria (p=0,000), escala de coma de Glasgow <8 puntos (p=0,000) y complicaciones neurológicas como la hipertensión endocraneana (p=0,010). Conclusiones: Los factores neurológicos asociados a la mortalidad fueron la ausencia de reflejos del tallo encefálico, anisocoria, escala de coma de Glasgow <8 puntos y complicaciones neurológicas como la hipertensión endocraneana(AU)

Introduction: Cerebrovascular accident is one of the commonest causes of mortality in the world. Objective: To determine the association between development of neurological disorders and the need for mechanical ventilation with an increased incidence of mortality in the intensive care unit. Methods: An observational, prospective and cross-sectional study was carried out in the intensive care unit of a secondary care hospital. The study population consisted of 52 patients with cerebrovascular accident who received artificial respiratory support between 2018 and 2020. The final variable of interest was mortality. The neurological factors studied were type of cerebrovascular accident, score according to the Glasgow coma scale, absence of brainstem reflexes, anisocoria, and neurological complications. The level of significance was determined according to P ≤ 0.05, through chi-square of independence. Results: Proportional mortality prevailed in hemorrhagic cerebrovascular accident of nontraumatic intracranial hemorrhage type (P=0.118), absence of brainstem reflexes (P=0.000), anisocoria (P=0.000), score of less than eight points according to the Glasgow coma scale (P=0.000), and neurological complications such as endocranial hypertension (P=0.010). Conclusions: The neurological factors associated with mortality were absence of brainstem reflexes, anisocoria, score of less than eight points according to the Glasgow coma scale, and neurological complications such as endocranial hypertension(AU)

Accidente cerebrovascular isquémico en un adulto joven

RESUMEN Presentamos caso de un varón de 39 años con antecedentes de varios accidentes isquémicos transitorios que siempre resolvieron rápida y espontáneamente. Fue sometido a varios estudios cardiovasculares, neurovasculares y de neuro y angioimagen que resultaron normales. El paciente se presentó a consulta con una paresia facio-braquial derecha y disartria. Sin embargo, el cuadro cedió en el transcurso de horas a pesar de manifestarse una isquemia en los estudios neurovasculares. Por todo lo anterior se decidió estudiar trombofilias presentándose el resultado de una mutación del gen G20210A de la protrombina. Al alta, en tratamiento con anticoagulantes orales, el paciente se presenta asintomático con monitoreo mensual continuo.

ABSTRACT We present the case of a 39-year-old man with a history of several transient ischemic attacks that always resolved quickly and spontaneously. He underwent several cardiovascular, neurovascular, and neuro and angioimaging studies that were normal. The patient presented for consultation with a right faciobrachial paresis and dysarthria. However, the condition subsided within hours despite ischemia manifested in neurovascular studies. For all the above, it was decided to study thrombophilias, finding the prothrombin G20210A mutation. Upon discharge, on treatment with oral anticoagulants, the patient is asymptomatic with continuous monthly monitoring.
