My 87 year old mother in law (whom I live with) has had dementia for a couple of years now. It's got to the point where she collects kitchen roll sheets and toilet toll sheets in a box. She always has some tissue in her hands or pockets. She usually just takes it straight off the roll and throws it straight in the bin! It's costing a fortune - 9 rolls every 2-3 days. Also she constantly runs the taps and throws 2-3 jugs of water down the toilet before flushing it (even if she hasn't been to the toilet). I am at my wits end. Her actions wake up the family at night and she seems exhasted by her constant trips to the kichen and bathroom. P.S. She has got bladder problems but wears continence products which carers change 3 times a day (she has been recently tested for a uti but is clear). Any advice would be greatly appreciated as my husband and I are close to breaking point. We find it so hard to explain the behaviour to our 3 year old - who has started to copy my mother in law's actions because she thinks it's funny.
