@janet7 My mother had dementia plus Alzheimers. My dad took a walk alone each morning, to "set" his mind/day. Later, he would encourage her to go for a walk, even a short one, to say "hi" to anyone out, or to look at "pretties". She really liked meeting up with the neighborhood pets. For her, a schedule included different things on different days, based on what she was showing interest in. He didn't try to keep to a particular time frame except mealtimes, rather to keep the continuity of the activity itself. She eventually became mute, with a "lights are on but no one is home" expression. She stayed in their house until 2 weeks before her passing, when she no longer would take any nourishment.

Does this make sense?

Yes, predictability is the way to help them, but there needs to be flexibility as well. There are many variables that come into play: They might take a nap just when you’re ready to walk, or a nurse or friend may be visiting, or a visit to the doctor is necessary, or their favorite TV show is on, or a long bathroom break. I feel regardless of whatever gets in the way, the walk itself is the most important part of their day. Sometimes I’m not feeling well and have to adjust my schedule. Meals are pretty consistent and bedtime, taking meds, waking and sleeping times are also consistent.
And of course your caring and love is the most important help of all.
