The natural tendency for all caregivers is to try and explain, and sometimes in a heated fashion, that we did not do what we are being accused of by a dementia patient.
For example, it is not uncommon for dementia patients to say someone is stealing money from them. It is also fairly common for women living with Alzheimer's to guard their purse. Even to take it to bed with them at night.
It is one thing when a dementia patient accuses someone else of stealing, and totally different when they accuse you, the primary caregiver of stealing.
Somehow we don't get as upset when someone other than ourselves is being accused.
However, when we are being falsely accused we have a need to defend ourselves, and our reputation.
Have you ever been falsely accused by someone suffering from Alzheimer's?
