Are obsessions a recognised symptom of early dementia? My MIL has obsessions which drive us to distraction. There is usually ‘one on the go’ and when that one has been forgotten / we have refused to comply with / we have done what is asked, it disappears to be very shortly replaced by another. There are other concerns about her behaviour - she writes EVERYTHING down and has so many lists / bits of paper that she sometimes can’t find the necessary bits of paper. She has no concept of the bigger picture re money. She can cope with what’s in her purse but can’t grasp how much money she actually has in total. She has her name down for a residential care home - she’s almost 90 and this is her choice- but she’s terrified her money will run out. We have carefully explained that she could live to over 100 and still have money, but she just can’t grasp that concept. Her short term memory is poor - hence the writing everything down. She is also very egocentric. Could these all be attributed to ‘old age’ or from your experience are we facing another parent with dementia? We have already had 2 with dementia. Your thoughts would be much appreciated.
