Next Sunday we have to take our mother (81), who has severe, advanced dementia, to an NHS drive through Covid 19 testing centre for a swab test. This is a mandatory procedure prior to an operation she has to have. It will be a severely traumatic experience for her (and us). We have been advised by her GP to sedate her beforehand although we fear that won't help much. Does anyone have any experience of having to go through the same procedure with someone with dementia? Any advice or insights would be gratefully received. Thank you.
