Hello, My mum has been diagnosed with Alzheimers and vascular dementia. I have been caring for her for several years, but Social Services are now helping me by providing agency carers. SS have suggested that my husband and I would benefit from a break and have offered to put mum in a home for a week. The home is experienced with managing dementia folk, but lock the dementia residents in their room overnight. Is this normal ? I am horrified.
