Changes in long-term care cannot be entirely attributed to advances in designing for people with dementia. This decrease in unit size, however, reflects a substantial change from the traditional 60- bed units that prevailed in earlier decades change that coincides with a proliferation of dementia design guidance and with the rapid development of SCUs for people with dementia. Similarly, dining rooms and kitchens are increasingly found on all long-term care units/households, not only in those for people with dementia. In many ways, the impact of design for people with dementia has spread far
beyond serving the needs of cognitively impaired individuals,and is considered more supportive for all residents of long-term care facilities.
