Metodologia Intervencion comunitaria, con seleccion aleatoria y grupo control. 30 participantes en cada grupo. En ambos grupos se aplico PAE (excepto intervencion) con taxonomia NANDA- NIC-NOC. Se valoraron los 13 dominios, el deficit cognitivo, la capacidad funcional y la dependencia. Se priorizaron tres diagnosticos y por cada uno se planearon tres resultados con escalas NOC de 4 indicadores cada una. Un grupo fue intervenido segun diagnostico relevante durante 10 sesiones, el otro siguio la rutina del CBA. Analisis comparativo de puntajes NOC. El incremento promedio de un punto por participante en cada NOC indico eficacia. Resultados Grupos similares excepto en genero (p=0,017), predominio de mujeres (60,0%). Adultos mayores de 75 anos (72,0%), con algun grado de demencia senil (63,0%) y alteraciones funcionales marcadas en flexibilidad y agilidad. En puntajes NOC no hubo diferencias significativas entre grupos. Intervencion eficaz en cuatro NOC: Deambulacion: caminata, tolerancia a la actividad, forma fisica y resistencia.

Adults over 75 years (72,0%), with some degree of senile dementia (63,0%) and functional alterations marked in flexibility and agility.
