- Change From Baseline in Nighttime Total Sleep Time [ Time Frame: Baseline, 14 days follow-up ]Mean of Nighttime Total Sleep Time (in minutes) during the 12-h nocturnal epoch 8:00 PM - 08:00 AM after 2 weeks under treatment
- Change From Baseline in Nighttime Number Of Awakenings [ Time Frame: Baseline, 14 days follow-up ]Change in scores from baseline to intervention week was analyzed using an analysis of covariance (ANCOVA) with the change score as the dependent variable and the treatment condition and baseline score as independent variables.
- Change From Baseline in Nighttime Wake After Sleep Onset [ Time Frame: Baseline, 14 days follow-up ]Nighttime Wake After Sleep Onset (in minutes) after sleep onset until the final awakening during the 12-h nocturnal epoch 8:00 PM - 08:00 AM. After 2 weeks under treatment.
- Change From Baseline in in Daytime Total Sleep Time [ Time Frame: Baseline, 14 days follow-up ]

Mirtazapine has been used for depressed elderly with sleep disorders with good tolerability and efficacy. The study hypothesis is that mirtazapine could also be used in demented with sleep disorders.
Sleep disorders (SD) affects 35 to 50 percent of patients with Alzheimer Disease (AD). These disorders often make caring for patients at home very difficult and It's also associated with higher risk of institutionalization and increases health care costs. Treatment of SD in people with dementia may benefit both patients and their caregivers. However, little is known about the efficacy of pharmacological treatments for treating sleep disturbances in AD.
