RESUMEN
El objetivo del presente estudio fue determinar los efectos de 5 mg. de melatonina de liberación inmediata sobre la macro-arquitectura del sueño en ocho pacientes con diagnóstico de Demencia Tipo Alzheimer (DTA) de media a moderada. Utilizando la técnica polisomnográfica (PSG) se realizó un estudio simple ciego, no aleatorio, controlado con placebo. Los registros PSG se llevaron a cabo de la siguiente manera: Noche 1: administración de placebo; noche 2 y 3: administración continua de melatonina (5 mg). Observamos que el tratamiento con melatonina durante la primera noche de administración disminuyó significativamente la latencia de la fase 2, del sueño de ondas delta y el sueño de MOR al ser comparadas con el placebo (P ≤.05). No se observaron diferencias significativas en el tiempo total de cada fase de sueño; tampoco se observaron diferencias en la eficiencia del sueño en presencia de la melatonina. Sin embargo se observó una tendencia a la disminución del tiempo total de vigilia y un aumento del tiempo total de sueño, principalmente durante la segunda noche de tratamiento. Concluimos que la melatonina puede mejorar el sueño en pacientes con DTA de media a moderada.
