ABSTRACT

La utilidad de la recreación física con carácter lúdico resulta un medio fundamental para mejorar la salud, las funciones cognitivas y la calidad de vida. A partir de un diagnóstico aplicado a una muestra de 19 adultos mayores, estos presentaron insuficiencias en los procesos de la memoria; en tal sentido, se comprobó que las propuestas de actividades físico-recreativas dirigidas a este grupo etario fueron muy generales, no atendieron las características morfofuncionales y estuvieron limitadas en la variedad de ofertas recreativas. La presente investigación tuvo como objetivo mejorar las funciones cognitivas, que se relacionan con la memorización, en los adultos mayores de la comunidad Matahambre, del municipio Songo la Maya, a través de la marcha de orientación. Se emplearon como métodos teóricos el analítico-sintético e inductivo-deductivo; y empíricos, el análisis documental, la observación, la encuesta y la entrevista que permitieron obtener los datos e informaciones necesarias para la correcta realización de la marcha de orientación al tomar en cuenta las características de este grupo poblacional. La propuesta demostró la marcha de orientación como una importante herramienta que estimuló las capacidades memorísticas y los recuerdos, al tomar en cuenta los gustos, preferencias, necesidades e intereses del adulto mayor, resultarles atractiva y permitirles recordar aspectos o emociones vitales de su vida personal.

A proposta demonstrou a caminhada de orientação como uma importante ferramenta que estimulou habilidades de memória e lembranças, ao levar em conta os gostos, preferências, necessidades e interesses do idoso, tornando-a atrativa para ele e permitindo-lhe relembrar aspectos vitais ou emoções de sua vida. vida pessoal.


The usefulness of physical recreation with a playful character for this group of people is a fundamental means to improve their health, their cognitive functions and their quality of life. From a diagnosis applied to a sample of 19 older adults, it was possible to know the insufficiencies in memoristic events that these subjects had. In this sense, it was also found that the proposal of physical-recreational activities aimed at this age group in the community are very general and do not take into account their morpho-functional characteristics. They are limited in terms of the variety of recreational offers for this population group. The objective of this research is to improve cognitive functions, which are related to memorization, in older adults of the "Matahambre" community of the Songo la Maya municipality through orientation walking. For the solution of the objective, theoretical methods such as: analytical-synthetic and inductive-deductive were used. Among the empirical methods, documentary analysis, observation, survey and interview were used to obtain the necessary data and information for the correct implementation of the orientation walk, taking into account the characteristics of this population group. The proposal showed that the orientation walk is an important tool that stimulates the memory and memory capacities of these people, by taking into account their tastes, preferences, needs and preferences.

ABSTRACT

In the pediatric population, epilepsy is one of the most common neurological disorders that often results in cognitive dysfunction. It affects patients' life quality by limiting academic performance and self-esteem and increasing social rejection. There are several interventions for the neurohabilitation of cognitive impairment, including LEGO®-based therapy (LEGO® B-T), which promotes neuronal connectivity and cortical plasticity through the use of assembly sets and robotic programming. Therefore, the aim of this study was to analyze the effect of LEGO® B-T on cognitive processes in pediatric patients with epilepsy. Eligible patients were identified; in the treatment group, an initial evaluation was performed with the NEUROPSI and BANFE-2 neuropsychological tests. Then, the interventions were performed once a week, and a final test was performed. In the control group, after the initial evaluation, the final evaluation was performed. An overall improvement was observed in the LEGO® B-T patients, with a significant increase in BANFE-2 scores in the orbitomedial, anterior prefrontal, and dorsolateral areas. In addition, in the gain score analysis, the orbitomedial and memory scores were significantly different from the control group. LEGO® B-T neurohabilitation is a remarkable option for epilepsy patients, who are motivated when they observe improvements.

ABSTRACT

Autism spectrum disorder (ASD) is a neurodevelopmental condition that exhibits a widely heterogeneous range of social and cognitive symptoms. This feature has challenged a broad comprehension of this neurodevelopmental disorder and therapeutic efforts to address its difficulties. Current therapeutic strategies have focused primarily on treating behavioral symptoms rather than on brain psychophysiology. During the past years, the emergence of non-invasive brain stimulation techniques (NIBS) has opened alternatives to the design of potential combined treatments focused on the neurophysiopathology of neuropsychiatric disorders like ASD. Such interventions require identifying the key brain mechanisms underlying the symptomatology and cognitive features. Evidence has shown alterations in oscillatory features of the neural ensembles associated with cognitive functions in ASD. In this line, we elaborated a systematic revision of the evidence of alterations in brain oscillations that underlie key cognitive processes that have been shown to be affected in ASD during childhood and adolescence, namely, social cognition, attention, working memory, inhibitory control, and cognitive flexibility. This knowledge could contribute to developing therapies based on NIBS to improve these processes in populations with ASD.

ABSTRACT

BACKGROUND: The ageing population has increased the prevalence of disabling and high-cost diseases, such as dementia and mild cognitive impairment (MCI). The latter can be considered a prodromal phase of some dementias and a critical stage for interventions to postpone the impairment of functionality. Working memory (WM) is a pivotal cognitive function, representing the fundamental element of executive functions. This project proposes an intervention protocol to enhance WM in these users, combining cognitive training with transcranial electrical stimulation of alternating current (tACS). This technique has been suggested to enhance the neuronal plasticity needed for cognitive processes involving oscillatory patterns. WM stands to benefit significantly from this approach, given its well-defined electrophysiological oscillations. Therefore, tACS could potentially boost WM in patients with neurodegenerative diseases. METHODS: This study is a phase IIb randomised, double-blind clinical trial with a 3-month follow-up period. The study participants will be 62 participants diagnosed with MCI, aged over 60, from Valparaíso, Chile. Participants will receive an intervention combining twelve cognitive training sessions with tACS. Participants will receive either tACS or placebo stimulation in eight out of twelve training sessions. Sessions will occur twice weekly over 6 weeks. The primary outcomes will be electroencephalographic measurements through the prefrontal theta oscillatory activity, while the secondary effects will be cognitive assessments of WM. The participants will be evaluated before, immediately after, and 3 months after the end of the intervention. DISCUSSION: The outcomes of this trial will add empirical evidence about the benefits and feasibility of an intervention that combines cognitive training with non-invasive brain stimulation. The objective is to contribute tools for optimal cognitive treatment in patients with MCI. To enhance WM capacity, postpone the impairment of functionality, and obtain a better quality of life.

ABSTRACT

BACKGROUND: In recent years, the use of virtual reality (VR) as a complementary intervention in treating cognitive impairment has significantly increased. VR applications based on instrumental activities of daily living (iADL-VR) could offer a promising approach with greater ecological validity for intervention in groups with cognitive impairments. However, the effectiveness of this approach is still debated. OBJECTIVE: This systematic review aims to synthesize the effects of iADL-VR interventions to rehabilitate, train, or stimulate cognitive functions in healthy adults and people with mild cognitive impairment (MCI) and different types of dementia. METHODS: A systematic search was performed in the Scopus, PubMed, IEEE Xplore, Web of Science, and APA PsycNet databases until September 2022 and repeated in April 2023. The selected studies met the search terms, were peer-reviewed, included an iADL-VR intervention, and were written in English. Descriptive, qualitative studies, reviews, cognitive assessment, non-intervention studies, those unrelated to VR or iADL, those focused on motor aspects, and non-degenerative disorders were excluded. The PEDro scale was used to assess the methodological quality of the controlled studies. To present and synthesize the results, we organized the extracted data into three tables, including PEDro scores, participant characteristics, and study characteristics. RESULTS: Nineteen studies that met the inclusion and exclusion criteria were included. The total sample reached 590 participants, mostly women (72.67%). Approximately 30% were diagnosed with Alzheimer's disease or dementia, and 20% had mild cognitive impairment. Variables such as authors and year of publication, study design, type of intervention and VR applied, duration of the intervention, main findings, and conclusions were extracted. Regarding demographic characteristics, the sample size, age, sex, years of education, neurological diagnosis, dropouts, and the city and country where the intervention took place were recorded. Almost all studies showed improvements in some or all the outcomes after the intervention, generally greater in the iADL-VR group than in the control group. CONCLUSION: iADL-VR interventions could be beneficial in improving the performance of cognitive functions in older adults and people with MCI and different types of dementia. The ecological component of these tasks makes them very suitable for transferring what has been learned to the real world. However, such transfer needs to be confirmed by further studies with larger and more homogeneous samples and longer follow-up periods. This review had no primary funding source and was registered with PROSPERO under registration ID: 375166.

ABSTRACT

The study aimed to compare cognitive performance, depressive symptoms, and the incidence of falls in Brazilian older women with and without a confirmed history of COVID-19. This cross-sectional study included 188 women (60-89 years), divided into two groups: one with a history of COVID-19 (n = 139), and one without any history of COVID-19 (n = 49). The instruments used were the Cognitive Telephone Screening Instrument (COGTEL) test battery, the Trail Making Test (TMT), the Geriatric Depression Scale (GDS-15), and the self-reported history of falls since the beginning of mandatory confinement. The higher the age, the higher the incidence of falls. The highest prevalence of falls (57.1%) occurred in the COVID-19 group (p = 0.001), the members of which also indicated a better cognitive performance in the COGTEL test (p = 0.017), TMT-B (p = 0.004), and ∆TMT (B-A) (p = 0.004). In turn, the depressive symptoms were more severe in the COVID-19 group (p < 0.001). We observed that COVID-19 infection without hospitalization did not affect the cognitive performance of older adult women. Future studies should be carried out to monitor the mental health of older adult Brazilian women. Moreover, regardless of their history of COVID-19, older adults should participate in a physical training program focused on preventing falls.

ABSTRACT

Among the risk factors reported for cognitive decline, the literature highlights changes in body composition. Thus, the aim of the present study was to examine the relationship between obesity/overweight and executive functions in cognitively normal older adult women. This cross-sectional study included 224 individuals (60-80 years), stratified into normal weight (n = 45), overweight (n = 98), and obesity (n = 81). As outcomes, body mass index (BMI), waist circumference (WC), and Trail Making Test Parts A and B were assessed. We found positive correlations of BMI and WC with completion times of TMT-A and TMT-B, and a negative correlation of BMI and WC with education. ANCOVA showed an association between higher BMI and slower completion time of TMT-A, TMT-B, and ΔTMT (B-A). Impairment of executive functions of cognitively normal older women may be positively associated with obesity and negatively associated with years of education. The findings may contribute to designing strategies that make it possible to prevent cognitive decline in women during aging.

ABSTRACT

Abstract Alzheimer's disease (AD) is the most common neurodegenerative disease characterized by hippocampal, and cortical neuron deterioration, oxidative stress, and severe cognitive dysfunction. Aluminum is a neurotoxin inducer for cognitive impairments associated with AD. The treatment approaches for AD are unsatisfactory. Boswellia papyrifera and Syzygium aromaticum are known for their pharmacological assets, including antioxidant activity. Therefore, the current study explored the possible mitigating effects of a combination of Boswellia papyrifera and Syzygium aromaticum against aluminum chloride (AlCl3) induced AD. The AD model was established using AlCl3 (100 mg/kg), and the rats were orally administrated with Boswellia papyrifera or Syzygium aromaticum or a combination of them daily for 8 weeks. The Y-maze test was used to test cognition in the rats, while acetylcholinesterase (AChE) and oxidative stress markers were estimated in homogenates of the cerebral cortex and hippocampus. Also, the histopathological examination of the cortex and hippocampus were investigated. The results revealed that administration of either B. papyrifera or S. aromaticum extracts significantly improved the cognitive functions of AD rats, enhanced AChE levels, increased oxidative enzymes levels, including SOD and GSH, and reduced MDA levels in homogenates of the cerebral cortex and hippocampus and confirmed by improvement in histological examination. However, using a combination therapy gave better results compared to a single treatment. In conclusion, the present study provided primary evidence for using a combination of B. papyrifera and S. aromaticum to treat cognitive dysfunction associated with AlCl3 Induced AD by improving the AChE levels and modulating oxidative stress in the brain.


Resumo A doença de Alzheimer (DA) é a doença neurodegenerativa mais comum, caracterizada por hipocampo, deterioração dos neurônios corticais, estresse oxidativo e disfunção cognitiva grave. O alumínio é um indutor de neurotoxinas para deficiências cognitivas associadas à DA. As abordagens de tratamento para DA são insatisfatórias. Boswellia papyrifera e Syzygium aromaticum são conhecidos por seus ativos farmacológicos, incluindo atividade antioxidante. Portanto, o presente estudo explorou os possíveis efeitos atenuantes de uma combinação de Boswellia papyrifera e Syzygium aromaticum contra a DA induzida por cloreto de alumínio (AlCl3). O modelo DA foi estabelecido usando AlCl3 (100 mg/kg), e os ratos foram administrados por via oral com Boswellia papyrifera ou Syzygium aromaticum ou uma combinação deles diariamente por 8 semanas. O teste do labirinto em Y foi usado para testar a cognição nos ratos, enquanto a acetilcolinesterase (AChE) e marcadores de estresse oxidativo foram estimados em homogeneizados do córtex cerebral e hipocampo. Além disso, o exame histopatológico do córtex e hipocampo foram analisados. Os resultados revelaram que a administração de extratos de B. papyrifera ou S. aromaticum melhorou significativamente as funções cognitivas de ratos com DA, aumentou os níveis de AChE, aumentou os níveis de enzimas oxidativas, incluindo SOD e GSH, e reduziu os níveis de MDA em homogeneizados do córtex cerebral e hipocampo e confirmado pela melhora no exame histológico. No entanto, o uso de uma terapia combinada apresentou melhores resultados em comparação com um único tratamento. Em conclusão, o presente estudo forneceu evidências primárias para o uso de uma combinação de B. papyrifera e S. aromaticum para tratar a disfunção cognitiva associada à DA induzida por AlCl3, melhorando os níveis de AChE e modulando o estresse oxidativo no cérebro.

ABSTRACT

This review verified cognitive domains affected by type 1 diabetes mellitus (T1DM) and the instruments used for its assessment. We performed a search in three databases using the descriptors "type 1 diabetes" AND "cognitive dysfunction". Only six of the 120 articles found met the criteria for inclusion in the review. The anal-ysis of these articles indicates that the main cognitive functions compromised by T1DM are attention, visual attention, verbal memory, immediate and late recovery, and psychomotor speed. Among the selected articles, we found that the most used instruments were the Montreal Cognitive Assessment (MoCA), the Wechsler scales (WMS-III and WMS-RC), the Trail Making Test, The Grooved Pegboard, and substitution (letter-symbol, digit-symbol). Due to the different impairments found, we suggest the importance of standardizing a battery of cognitive assessments and greater efforts to understand the functional impairments resulting from dam-age to cognition in individuals with T1DM

ABSTRACT

Alzheimer's disease (AD) is the main cause of dementia worldwide. Emerging non-invasive treatments such as photobiomodulation target the mitochondria to minimize brain damage, improving cognitive functions. In this work, an experimental design was carried out to evaluate the effect of transcranial light therapy (TLTC) on synaptic plasticity (SP) and cognitive functions in an AD animal model. Twenty-three mice were separated into two general groups: an APP/PS1 (ALZ) transgenic group and a wild-type (WT) group. Each group was randomly subdivided into two subgroups: mice with and without TLTC, depending on whether they would undergo treatment with TLTC. Cognitive function, measured through an object recognition task, showed non-significant improvement after TLTC. SP, on the other hand, was evaluated using four electrophysiological parameters from the Schaffer-CA1 collateral hippocampal synapses: excitatory field potentials (fEPSP), paired pulse facilitation (PPF), long-term depression (LTD), and long-term potentiation (LTP). An improvement was observed in subjects treated with TLTC, showing higher levels of LTP than those transgenic mice that were not exposed to the treatment. Therefore, the results obtained in this work showed that TLTC could be an efficient non-invasive treatment for AD-associated SP deficits.

ABSTRACT

Nowadays, several strategies for treating neuropsychologic function loss in Parkinson's disease (PD) have been proposed, such as physical activity performance and developing games to exercise the mind. However, few studies illustrate the incidence of these therapies in neuronal activity. This work aims to study the feasibility of a virtual reality-based program oriented to the cognitive functions' rehabilitation of PD patients. For this, the study was divided into intervention with the program, acquisition of signals, data processing, and results analysis. The alpha and beta bands' power behavior was determined by evaluating the electroencephalography (EEG) signals obtained during the execution of control tests and games of the "Hand Physics Lab" Software, from which five games related to attention, planning, and sequencing, concentration, and coordination were taken. Results showed the characteristic performance of the cerebral bands during resting states and activity states. In addition, it was determined that the beta band increased its activity in all the cerebral lobes in all the tested games (p-value < 0.05). On the contrary, just one game exhibited an adequate performance of the alpha band activity of the temporal and frontal lobes (p-value < 0.02). Furthermore, the visual attention and the capacity to process and interpret the information given by the surroundings was favored during the execution of trials (p-value < 0.05); thus, the efficacy of the virtual reality program to recover cognitive functions was verified. The study highlights implementing new technologies to rehabilitate people with neurodegenerative diseases.

ABSTRACT

Introducción: Las bases del comportamiento humano y la capacidad de interacción con todo lo que está a su alrededor están fundamentadas en los mecanismos cognitivos. Profundizar en el estudio de los efectos de la actividad física sobre el rendimiento de los mismos posee gran relevancia. Objetivo: Describir la influencia de la actividad física en las funciones y habilidades cognitivas. Métodos: Se realizó un estudio de revisión bibliográfica en las bases de datos Web of Science, Scopus, Dialnet, PubMed, ERIC, SPORTDiscus y PsycINFO. Luego de aplicar criterios de inclusión/exclusión, fueron seleccionados 62 artículos. Desarrollo: Como respuesta al ejercicio físico, mejora el funcionamiento del metabolismo neuronal y mitocondrial a través de la regulación de vías vasculares, metabólicas e inflamatorias. La actividad física influye positivamente en la plasticidad sináptica, lo cual mejora la función visoespacial, la velocidad de procesamiento, la resolución de problemas, el rendimiento académico, la atención sostenida y la función ejecutiva. Conclusiones: La actividad física influye positivamente en el funcionamiento cerebral y, por tanto, en los procesos cognitivos. Una condición física óptima, así como niveles moderados y vigorosos de actividad física, tienen un impacto favorable en las funciones cognitivas(AU)

ABSTRACT

Resumen Los pacientes diagnosticados con Enfermedad de Parkinson (EP) presentan alteraciones motoras concomitantes a otras alteraciones de tipo cognitivo, conductual o emocional. Una de las alternativas al tratamiento farmacológico es la estimulación cerebral profunda (ECP). Existen reportes de alteraciones en el rendimiento de tareas cognitivas tras procedimiento de ECP, lo que podría sugerir que el procedimiento es responsable de estos cambios cognitivos. El objetivo del estudio fue comparar los resultados del rendimiento en pruebas cognitivas de pacientes con EP de dos grupos (con ECP y sin ECP). Se recolectaron los resultados de 47 pacientes (n = 16 ECP; n = 31 sin ECP) durante los años de 2011 hasta 2015. Dentro de las funciones y variables evaluadas se encuentran: categorización visual, flexibilidad cognitiva, solución de problemas, atención selectiva, velocidad de procesamiento, inhibición conductual y calidad de vida. En general, no se encontraron diferencias significativas entre los grupos en las funciones evaluadas. En el grupo de participantes con ECP, se encontró mayor cantidad de correlaciones entre las pruebas de semejanzas y las de dígitos inversos, listas de palabras, búsqueda de símbolos y las subpruebas del Wisconsin Card Sorting Test. Así mismo, en los pacientes con ECP se presentó una percepción menor de calidad de vida asociada al tiempo de la enfermedad en comparación con el grupo sin ECP. En conclusión, estos resultados son congruentes con estudios similares de evaluación neuropsicológica y se discute el papel del tratamiento de estimulación en los pacientes, los cuales no siempre tienen un impacto positivo sobre la calidad de vida percibida.


Abstract Patients diagnosed with Parkinson's disease show motor alterations together to cognitive, behavioral, and emotional disturbances. An alternative treatment to the exclusive pharmacological medication is the Deep Brain Stimulation procedure (DBS). Some studies have shown altered behavioral patterns after DBS device implantation, suggesting a relationship between a particular performance in cognitive tests derived from the DBS procedure. Our study aimed to compare the performance of cognitive tests in Parkinson's disease patients with and without DBS. Results were analyzed from 47 patients (n = 16 DBS; n = 31 without DBS) in a range since 2011 to 2015. Functions tested were visual categorization, cognitive flexibility, problem solutions, selective attention, cognitive processing speed, behavioral inhibition, and quality of life. In general, there are non-significative differences between groups in functions tested. However, correlations were found depending on the group (DBS or without DBS patients), with more positive correlations inside the DBS group between the similarity test and inversed digits, list of words, symbol search and the sub-test of the Wisconsin Card Sorting Test. In addition, the DBS group showed a low perception of the quality of life associated with the disorder´s time compared to the without DBS group. In conclusion, these results are congruent with similar studies of neuropsychological evaluation, and the role of treatment is discussed below the perception of the quality of life.

ABSTRACT

Objetivo: determinar las funciones cognitivas afectadas en un grupo menores trabajadores y la diferencia en el perfil neuropsiquiátrico de estos respecto a un grupo de menores no trabajadores. Metodología: investigación de diseño no experimental, de tipo transversal, prospectivo y analítico con un muestreo aleatorio simple. Resultados: el trabajo infantil no afecta todas las funciones cognitivas. Los puntajes obtenidos en las pruebas de habilidades gráficas, percepción táctil, percepción auditiva, memoria de evocación visual, lenguaje de repetición, lenguaje de comprensión, habilidades espaciales y atención auditiva estaban en rangos normales para ambos grupos. Sin embargo, los puntajes en las pruebas de construcción con palillos, memoria de codificación visual, percepción visual, memoria de evocación auditiva, lenguaje expresivo, atención visual, habilidades conceptuales, fluidez verbal y fluidez gráfica se encuentran por debajo de lo esperado para ambos grupos. Conclusión: las dificultades que presentan tanto el grupo de menores trabajadores como el de no trabajadores se podrían explicar por las condiciones de vida de la población, lo que suscita la hipótesis de que la pobreza y la escasez en la estimulación ambiental afectan el desarrollo cognitivo tanto como el trabajo infantil.


Objective: The purpose of this investigation was to determine the cognitive functions affected in a group of working minors and the difference in their neuropsychiatric profile as compared to that of a group of non-working minors. Methodology: non-experimental, cross-sectional, prospective and analytical design with a simple random sampling. Results: It was observed that child labor does not affect all cognitive functions. The scores obtained in the graphic skills, tactile perception, auditory perception, visual evocation memory, repetition language, comprehension language, spatial skills and auditory attention tests are in normal ranges for both groups. However, the scores on the stick construction, visual coding memory, visual perception, auditory evocation memory, expressive language, visual attention, conceptual skills, verbal fluency, and graphic fluency tests are lower than expected for both groups. Conclusion: The difficulties presented by both the group of working minors and nonworking minors could be explained by the conditions of the population, which raises the hypothesis that the conditions of poverty and scarcity in the environmental stimulation to which children are exposed in non-working minors affect cognitive development as much as child labor.


Objetivo: determinar as funções cognitivas afetadas num grupo menores trabalhadorese a diferença no perfil neuropsiquiátrico destes com respeito a um grupo de menores não trabalhadores. Metodologia: investigação de desenho não experimental, de tipo transversal, prospectivo e analítico com uma amostragem aleatório simples. Resultados: o trabalho infantil não afeta todas as funções cognitivas. As pontuações obtidas nas provas de habilidades gráficas, percepção táctil, percepção auditiva, memóriade evocação visual, linguagem de repetição, linguagem de compreensão, habilidades espaciais e atenção auditiva estavam em faixas normais para ambos os grupos. Embora, as pontuações nas provas de construção com pauzinhos, memória de codificação visual, percepção visual, memória de evocação auditiva, linguagem expressivo, atenção visual, habilidades conceptuais, fluidez verbal e fluidez gráfica se encontram por debaixo do esperado para ambos os grupos. Conclusão: as dificuldades que apresentam tanto no grupo de menores trabalhadores quanto no de não trabalhadores se poderiam explicar pelas condições de vida da população, o que suscita a hipótese de que a pobreza e a escassez na estimulação ambiental afetam o desenvolvimento cognitivo tanto como o trabalho infantil.

Introduction: Functional capacity is decreased in people with Cardiovascular Diseases and Chronic Respiratory Diseases. These diseases have also been associated with cognitive dysfunction. The study examines the efficacy of a cardiopulmonary rehabilitation program in the recovery of functional capacity and analyzes whether subjects with cardiopulmonary diseases suffer from cognitive dysfunction. Materials and methods: Participated 50 adults with medium-high education who completed a cardiopulmonary rehabilitation program of between 3 and 6 months based on physical education, nutritional education, promotion of healthy habits and medication management. Functional capacity was evaluated with the Duke index at the beginning and end of the program. Memory and language tests were also administered, for the only time, at the beginning of the program, comparing the values obtained with Argentine normative studies. The data was analyzed with the Wilcoxon test, bivariate correlations, and linear regression. Results: Functional capacity increased significantly at the end of the program. In any case, the post-program Duke value suggests that the functional capacity of the patients continues to be affected. On the other hand, a memory test explained 10,8% of the variance in the Duke index, and there are no findings of cognitive dysfunction. Conclusion: The functional capacity of cardiopulmonary patients improved with the rehabilitation program, although this improvement is clinically insufficient. Better memory performance predicted greater functional capacity, which is why it is suggested to add cognitive stimulation workshops to cardiopulmonary rehabilitation programs. This sample with cardiopulmonary disease does not present cognitive dysfunction, probably due to its high cognitive reserve.

Introducción: La capacidad funcional está disminuida en personas con Enfermedades Cardiovasculares y Enfermedades Respiratorias Crónicas. Estas enfermedades también han sido asociadas a disfunción cognitiva. El estudio examina la eficacia de un programa de rehabilitación cardiopulmonar en la recuperación de la capacidad funcional, y analiza si sujetos con enfermedades cardiopulmonares sufren disfunción cognitiva. Materiales y métodos: Participaron 50 personas adultas con instrucción media-alta que completaron un programa de rehabilitación cardiopulmonar de entre 3 y 6 meses basado en educación física, educación nutricional, promoción de hábitos saludables y manejo de medicación. Se evaluó la capacidad funcional con el índice Duke al iniciar y finalizar el programa. Se administró también, por única vez, al iniciar el programa, pruebas de memoria y de lenguaje, comparando los valores obtenidos con estudios normativos argentinos. Se analizó los datos con test Wilcoxon, correlaciones bivariadas y regresión lineal. Resultados: La capacidad funcional aumentó significativamente al finalizar el programa. De todos modos el valor Duke pos- programa sugiere que la capacidad funcional de los pacientes continúa afectada. Por otro lado, una prueba de memoria explicó el 10,8% de la varianza en el índice Duke, y no hay hallazgos de disfunción cognitiva. Conclusión: La capacidad funcional de los pacientes cardiopulmonares mejoró con el programa de rehabilitación, aunque dicha mejora, es clínicamente insuficiente. Mejor rendimiento de memoria predijo mayor capacidad funcional, por lo que se sugiere añadir talleres de estimulación cognitiva a los programas de rehabilitación cardiopulmonares. Esta muestra con enfermedad cardiopulmonar no presenta disfunción cognitiva, probablemente por su elevada reserva cognitiva.

ABSTRACT

Juvenile myoclonic epilepsy (JME) is a benign disorder with a good response to antiepileptic drugs. Neuropsychological evaluations revealed mild cognitive deficits. The objective of this study is to determine the cognitive profile and mood symptoms in JME compared to normal controls. 30 patients with JME and 29 controls matched for age, gender, and education level were prospectively evaluated. The clinical characteristics were analysed. They were given a complete cognitive battery, a self-administered questionnaire of executive difficulties (DEX), the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), Beck Depression Inventory (BDI), Generalized Anxiety Disorder Scale (GAD-7) and suicide risk scale (MINI). No significant differences in age and education were observed between JME and controls. Average time of evolution of the disease 18 years, 53% have three types of seizures: myoclonic, absence seizures and tonic-clonic seizures. Significant differences were found with greater failures in attention, executive function, a significantly higher score values in DEX in JME subjects. A higher score was found in the NDDI-E; BDI and GAD-7. No differences were found in the risk of suicide with respect to controls. The study confirms that JME presents greater failures in attentional functioning and executive skills related to flexibility and inhibition, with patients being aware of their difficulties in most cases. Knowing these difficulties would allow a better therapeutic approach to improve symptoms usually dismissed.

El objetivo de este estudio es determinar el desempeño cognitivo y síntomas anímicos de la EMJ comparados con controles normales. Se evaluaron en forma prospectiva 30 pacientes con EMJ y 29 controles pareados por edad, género, y escolaridad. Se analizaron las características clínicas de la EMJ. Se administró una batería cognitiva completa, un cuestionario auto-administrado de dificultades ejecutivas (DEX), un inventario de depresión validado para epilepsia NDDI-E, escala de depresión de Beck (BDI), escala de ansiedad (GAD-7) y escala de riesgo de suicidio (MINI). Sin diferencias significativas en edad y escolaridad ent re EMJ y controles. Tiempo medio de evolución de la enfermedad, 18 años. El 53% presentó tres tipos de crisis, mioclonías, ausencias y convulsiones tónico-clónicas generalizadas. Hubo diferencias significativas con mayores fallas en atención, funciones ejecutivas, un puntaje significativamente mayor en el DEX en pacientes con EMJ. Se encontró un mayor puntaje en el NDDI-E, BDI y GAD-7 en EMJ. No se hallaron diferencias en el riesgo de suicidio respecto a controles. El estudio confirma que la EMJ presenta mayores fallas en el funcionamiento atencional y las habilidades ejecutivas relacionadas con la flexibilidad e inhibición, siendo en la mayoría de los casos los pacientes conscientes de sus dificultades. Conocer estas dificultades permitirá un mejor abordaje terapéutico, y mejorar síntomas muchas veces desestimados.

ABSTRACT

Acquired brain injury (ABI) commonly causes cognitive dysfunction that needs to be assessed and treated to maximize rehabilitation outcomes. Research suggests that music, emotion, and cognition are intimately linked, and that music can contribute to the assessment and treatment of cognitive functions of adults who have suffered from ABI. To this date, no standardized music based assessment tool exists to identify and measure cognitive functioning and mood states of Spanish-speaking persons with ABI at treatment intake and over time. The objective of this study was to develop such a scale and determine its psychometric properties in terms of internal consistency, reliability, and concurrent validity. The "Evaluación de la Cognición Musical para Adultos con Lesión Cerebral Adquirida" (in English "Music Based Assessment for Cognitive Functions of Adults with Acquired Brain Injury - ECMUS") was developed and tested at a neurorehabilitation institute in Argentina. Twenty-four healthy adults and 20 adults with ABI were recruited and assessed with the ECMUS. Despite the limited number of participants, this preliminary psychometric examination shows promising results. The tool has an acceptable internal consistency, excellent test-retest and inter-rater reliability, and, depending on the subscale, weak to strong correlations to related, nonmusical constructs. Overall, this pilot study opens the possibility to further explore the inclusion of music in assessment procedures of Spanish-speaking individuals with ABI in rehabilitation settings. It is clinically derived and emphasizes evidence-based contributions of the field of music therapy to interdisciplinary assessment and treatment in rehabilitation settings.
