We have suspected my mum has dementia for a couple of years but she has refused memory tests. After falling down the stairs over Christmas a hospital stay meant nurses recognised the issues and she has a memory clinic appointment in early feb. We don’t yet have LPA but obviously want to set this up ASAP but have been told once we have a diagnosis her mental capacity will be challenged. Are these the correct facts? Although she can engage in conversation it is sometimes like trying to piece a jigsaw together as her sentences can be jumbled/ missing words. Not sure if this would be classed as lacking in capacity?
