To make Alzheimer’s patients sleep, the following approaches can be taken: 1. Delay the bedtime and reduce non-sleeping behaviors in bed to achieve mild sleep deprivation and induce patients to fall asleep. 2. Sandalwood, vegetation or warm-toned objects can be placed in the bedroom, which can also quiet patients and make them fall asleep as early as possible. 3. Allow patients to perform appropriate exercises after dinner to put them in a mildly fatigued state so that they can fall asleep more quickly. 4.Reduce daytime sleep time to avoid sleep-wake cycle disorders. 5.Tell patients to take drugs such as Donepezil, Olanzapine and other drugs for dementia treatment and control of psychiatric symptoms before bedtime to help them sleep, and if necessary, take drugs with sedative and sleeping effects such as Zopiclone, Eszopiclone, Vitamin B1, Pepto-Bismol and Melatonin.
