Resumen

La enfermedad de Alzheimer es una patología neurodegenerativa progresiva y se encuentra entre las formas más comunes de demencia en las personas mayores. Los cambios en la memoria son síntomas comunes y también en el habla y el lenguaje pueden ser signos de deterioro cognitivo. Los sistemas inteligentes tienen potencial como herramientas de apoyo al diagnóstico. Objetivo: Proponer un modelo de Red Neuronal Convolucional para clasificar la enfermedad de Alzheimer utilizando características extraídas de grabaciones de habla. Método: utilizamos segmentos de habla con y sin pausas de individuos sanos y con enfermedad de Alzheimer para extraer características y reconocer patrones en espectrogramas. Para entrenar el modelo utilizamos una validación cruzada estratificada de 5-folds. Resultados: Obtuvimos métricas de precisión, sensibilidad y especificidad del 97,37%, 97,04% y 97,62%, respectivamente. Conclusión: El modelo propuesto mostró resultados prometedores y podría contribuir al estudio de biomarcadores no invasivos que detecten tempranamente la enfermedad de Alzheimer.
