My mother came over for dinner yesterday, she's been worried for a while that her mental capabilities are declining but we've reassured her even though we've noticed it as well.
Yesterday it was as if she was cold, she was shivering and we asked if she was cold but she said it's just how she shakes now. She was also talking about going to a support group for a condition that she has recently been diagnosed with but several times she got the name of the condition wrong. My other parent has recently been diagnosed with dementia and needs to be in a care home and my mother is terrified that she is going the same way. Her brothers and both parents have/had dementia so there is a big family history of it.
She's noticeably aged over the last week, I see her several times a week usually but always once a week so I wouldn't necessarily expect to see a difference but it's very obvious this time.
