My mother in law is 78 and started seeing bugs in her house a month or so ago. There are none. She has become completely obsessed with cleaning her house and herself but will not listen to reason and is becoming verbally aggressive with us as she is adamant they are there. We took photographs of everything she thought was bugs - some chips in her laminate, paint chips, grass, dust etc but she insists that it is our eyes that are the problem and not hers. (Not the case) She refuses to go for an eyetest as her optician apparently told her a year ago that her eyesight was perfect. She is falling in the street, she has bumped her car 3 times this year alone and we are seriously worried about her. She point blank refuses to see her doctor or an optician. She has had cataract surgery in both eyes over the last 5 years. Her hearing is not good either although she will tell you that is perfect too. She is on Warfarin and attends a clinic regularly. However she is and always has been economical with the truth and will not allow us to attend any appointments with her.
What on earth can we do to make her see reason?
