Hi Roma   If someone with Alzheimer's is rendering a lot at night there are a number of things you can try. I would avoid medication unless you become desperate. Try to address some of the following issues first.   Think of their comfort: Make sure they have not had a heavy meal or drunk too much fluid before bedtime Do they need the bathroom? Are they warm/cool enough in bed Are they hungry? All these are just a few examples.   Then think about their environment Is the room well ventilated? Is lighting appropriate? Complete darkness can be frightening, heavy shadowing can also cause confusion/fear. A small dim light can help avoid accidents and be can be reassuring.   Try to delineate between day time and night time. Think about enough activities in the day so that they are tired before bedtime Avoid assisting them to bed too early Do not have stimulating activities before bedtime A warm bath, soft music, may help relax them-so might a warm milky drink   If they get up try not to engage them in conversation. Short sentences in a soft reassuring voice will help.   If these examples do not work seek help from heath care services and your doctor.   Good luck   Christine
