Abstract

Objetivo: Determinar el efecto de la terapia de reemplazo hormonal (TRH) sobre la función cognitiva en mujeres postmenopáusicas.

Métodos: Del registro de participantes en el “Estudio Maracaibo del Envejecimiento”, se seleccionaron 72 mujeres menopáusicas, entre 55 y 79 años. Treinta y seis mujeres fueron tratadas con TRH combinada continua con estrógenos equinos conjugados (EEC) y acetato de medroxiprogesterona (AMP) durante un año, y 36 mujeres no recibieron THR: controles, pareados. El grupo1: recibió EEC 0,625mg + AMP 2,5mg; el grupo2: EEC 1,25mg + AMP 5,0mg. A todas las mujeres se le aplicaron pruebas neuropsicológicas, antes y después del tratamiento.

Resultados: Al comparar cada grupo experimental y control consigo mismo al inicio y luego de 12 meses, se observaron cambios en el área de la memoria, especialmente acentuada en el grupo control. También se compararon las mediciones de cada grupo experimental con su respectivo grupo control luego de un año de la evaluación inicial, se observaron diferencias significativas a favor del grupo control 2 en las pruebas de memoria de reconocimiento, orientación y razonamiento .

Conclusiones: Los cambios en la función cognitiva, observados en esta muestra, no pueden ser atribuidos a la TRH.

Objective: to evaluate the effect of hormone replacement therapy (HRT) on cognitive function in posmenopausal women.

Methods: seventy two posmenopausal women aged 55-79 years were selected from the Aging Maracaibo Study. Thirty-six women were treated with combined continued HRT (conjugated equine estrogen-CEE plus medroxyprogesterone acetate-MPA) during one year: Group 1 were treated with CEE 0,625 mg plus MPA 2,5 mg; Group 2 were treated with CEE 1,25 mg plus MPA 5 mg. Thirty-six not treated women served as paired controls. Neuropsycological tests were performed in all women before and after treatment.

Results: after one year of treatment with any of the CEE/MPA regimens, no significant changes in memory, recognition, orientation and rationalization were noted as compared with paired control groups. Unexpectedly, in these controls, beneficial effects on cognitive parameters were observed.

Conclusion: HRT did not changed cognitive function after one year of follow-up in posmenopausal women.
