ABSTRACT

Resumen Introducción: La presente investigación estudió el sistema auditivo y las habilidades ejecutivas, específicamente la flexibilidad cognitiva, en población longeva y buscó aportar a la evidencia científica existente, el impacto que pueden tener ambas en la calidad de vida de la población adulta mayor. Objetivo: Se determinó la relación entre la función auditiva y la flexibilidad cognitiva de una población adulta mayor del municipio de Sincelejo, Colombia. Método: Se realizó un estudio cuantitativo, no experimental, correlacional, transversal, a una población de 140 adultos mayores, para la selección de la muestra se aplicó un muestreo intencional por criterios de inclusión (pertenecientes a la institución, que firmarán el consentimiento informado) y de exclusión (déficit cognitivo, diabetes, enfermedades neurológicas diagnosticadas, alteraciones visuales o auditivas, sobrepasar la edad del test), la muestra quedo conformada por 49 adultos mayores. Se empleó como instrumentos de recolección de la información para la audición, pruebas audiológicas de audiometría tonal y logoaudiometría; y para la medición de la función ejecutiva, Test de clasificación de tarjetas de Wisconsin. Resultados: se demostraron diferencias entre la variable respuesta de nivel conceptual del test entre los grupos de edad (p: 0,037), pérdidas auditivas de alta frecuencia entre leve y moderado (25-40DbBHL; 40-60DBHL), buen nivel de discriminación del habla, y una asociación estadística entre sensibilidad auditiva y número total de errores (0,336, 0,357 p=0,05); la sensibilidad auditiva y las respuestas perseverativas y errores perseverativos (0,343, 0,301 p=0,05), discriminación del habla, respuesta a nivel conceptual (-0,375;-0,397p=0,0) y fallos para mantener actitud (0,441; 0,456 p=0,01). Conclusión: Cuanto mayor deterioro en el procesamiento periférico y central auditivo exista, mayor es la tendencia perseverativa, la dificultad para abstracción y formación de conceptos, así como el cambio de estrategias de un adulto mayor en tareas que impliquen funcionamiento ejecutivo.


Abstract Introduction: The present research study the auditory system and executive skills, specifically cognitive flexibility, in long-lived population to contribute to the existing scientific evidence, the impact that both can have on the quality of life of the elderly population. Objective: the relationship between the hearing function and cognitive flexibility an older adult population was determined in Sincelejo, Colombia. Method: A quantitative, non-experimental, correlational, cross-sectional study was conducted in a population (140) older adults, intentional sampling by inclusion criteria was applied for the selection of the sample (belonging to the institution, who will sign the informed consent) and exclusion (cognitive deficit, diabetes, diagnosed neurological diseases, visual or auditory alterations, exceeding the age of the test), the sample was made up of 49 older adults. It was used as instruments for collecting information for hearing, audiological tests of tone audiometry and logoaudiometry, for the measurement of executive function, Wisconsin Card Classification Test. Results: The results showed mean differences in the conceptual level response variable between age groups (p: 0.037), high-frequency hearing losses between mild and moderate (25-40Dbhl; 40-60Dbhl), good level of speech discrimination and a statistical association between hearing sensitivity and total number of mistakes (0.336, 0.357 p=0.05), and perseverance(0.343, 0.301 p=0.05), speech discrimination, response at the conceptual level(-0.375;-0.397p=0.0), lack of attitude(0.441; 0.456 p=0.01). Conclusion: The greater the deterioration in the peripheral and central auditory processing, the greater the perseverative tendency, the difficulty in abstraction and concept formation, as well as the change of strategies of an older adult in tasks that involve executive functioning.

ABSTRACT

OBJECT: The goals of radiosurgery include preservation of neurological function and prevention of tumor growth. We document the results of gamma-knife radio-surgery for vestibular schwannoma. METHOD AND OBJECT: Eighty-two patients underwent stereotactic radiosurgery for an vestibular schwannoma from October, 1994 to December, 2000. Sixty-five of these patients were followed up for radiological and clinical evaluation. As pregamma-knife modality, surgical resection were done in 23 patients,and V-P shunt in 2 patients. Initial symptoms were headache(n=45), dizziness(n=16), tinnitus(n=17). While normal facial function(House-Brackmann grade 1) was present in 48 patients(73.8%), other patients showed grade 2 function in 8, grade 3 function in 7,and grade 4 function in 2. The Gardner/Robertson scale was used to code hearing function. Male to female ratio was 1:3. Mean tumor volume was 7.98cm3. Mean dose delivered to the tumor margin was 14.2Gy,and mean maximal dose was 28.3Gy. RESULTS: Mean follow-up duration of 19.9 months. Thirty-five showed decrease(53.8%) in size, 19 patients(29.2%) stationary, 3(4.6%) initial decrease follow up increase, 5(7.6%) initial increase follow up decrease,and 59 patients (90.8%) were well controlled. Two patients experienced transient facial neuropathy, one transient trigeminal neuropathy, and one transient hearing deterioration. After gamma-knife radiosurgery, ventriculoperitoneal shunt was done in 4 patients. CONCLUSIONS: Gamma-knife radiosurgery can be used to treat postoperative residual tumors as well as in patients with concomitant medical problems in patients with preserved hearing function. Gamma-knife radiosurgery is safe and effective method to treat small, medium sized(less than 3cm in extracanalicular diameter), intracanalicular vestibular schwannoma, associated with low rate of cranial neuropathy.
