The elderly are a very important part of the Amish community, often looked to as those that can offer wise counsel.
A lot of Amish homes have an attached "Dawdy haus" consisting of a kitchen, living room, bathroom, and one or two bedrooms for grandparents to live in. Small and cozy, a Dawdy haus to me was always such a happy inviting place.
If extra care was needed in cases of Alzheimer's or being bedridden they were often moved from the Dawdy haus into the main house living room area where they had round the clock care.
Sometimes if the person being cared for is especially cantankerous or difficult, their children will take turns providing care for a month at a time.
If the elderly happened to be childless or single, nieces or nephews would step up to give them a home to stay in.
The golden years for elderly Amish are truly golden. Surrounded by loved ones and no fear of ever being put into a nursing home.
