Mum is 89 and has moderate dementia developing slowly and diagnosed as vascular dementia mainly, but has been on reminyl for about 4 years.  The abdominal pain is described by her as cramping abdominal pain along the mid-line at waist level. It is increasing in frequency and intensity over the last 5 months and is somewhat relieved when she stretches out in her electric armchair.  She has little appetite and now no longer can sit at the table to have a meal but only in this chair. The pain now even comes and wakes her at night and she has difficulty sleeping anyway.  She also has a craving for sweets which is hard to control as she replaces her meals with sweets. She is actually not frail and when not in pain is alert, can walk freely, likes to be active and go out and about and socialise.  She lives in her own home with full time live in carers.  She knows all the family and reads and writes well. Please advise what to do as we have seen many doctors with no diagnosis and reminyl has never been mentioned as a possible cause!
