My mother in law is diagnosed with both Alzheimers and Dementia and has extremely good in home care. Recently she is not bathing often, has frequent accidents but is not drinking much despite bringing her water very frequently, having a functioning sink and a water cooler in her room. Nevertheless often we catch her drinking she has taken to drinking from the toilet. We had to shut the water off because she was flooding the house with the clogs and running tank, and we don't want to cut off her use of the toilet and sink altogether when she needs the bathroom. She refuses adult diapers, sheets or portable toilets/ bedpans and flies into violent rages if anyone changes her routine. Does anyone have any ideas?
