CRUZ-AGUILAR, Manuel Alejandro; RAMIREZ-SALADO, Ignacio; CRUZ-ULLOA, Carlos  e  BENITEZ-KING, Gloria. Melatonin effects on macro arquitecture sleep in Alzheimer's disease patients. Salud Ment [online]. 2013, vol.36, n.4, pp.271-277. ISSN 0185-3325.

The objective of the present study was to evaluate the 5 mg. melatonin effects on the sleep macro-architecture in eight patients with middle to moderate Alzheimer's disease (DTA). Using the polysomnography technique (PSG), we made a simple-blind, non-randomized, controlled with placebo study. The PSG was carried out according to the following order: night 1: placebo administration; night 2 and 3: continues melatonin administration. In the first night with melatonin treatment, the sleep latency to the first episode of Stage 2, Delta and REM sleep, was significantly diminished as compared with placebo (≤.05). No significant difference in total time of each sleep stage and sleep efficiency was observed. Nevertheless, a tendency to diminish the total time of nocturnal wake and increase of the total sleep time in the second night with melatonin treatment was observed. We conclude that melatonin can improve sleep in patients with middle to moderate DTA.
