Hi, My dad (92) is in hospital with primarily a swallowing problem which has caused massive weight loss. He has had two main hallucinations that he has spoken about quite openly for a while now. A choir singing 'only a bird in a guilded cage (very old song!), in the road outside in the middle of the night, and another of people dancing above the train station behind the house. However on yesterdays visit to the hospital he was very animated about someone having driven a 6 seater settee into the ward and people popping out, waiters and tables, and on and on it went. He was insistent to almost the point of hysteria that it actually happened. We tried to reason with him, but for an hour and a half he just kept recounting the episode and elaborating upon it. My father has always been a highly intelligent logical man, and to see him like this was frightening. The hospital do memory tests etc on him, but just say that he is ok, very lucid. I feel this is because he sounds very convincing,and is more eloquent than the other patients. I feel this is the start of some kind of dementia, and as he is soon to be discharged to his home where he lives alone (I live abroad, as does my sister), I am obviously very worried. The doctor did not think it was due to any medication change. Looking back over the months I think this delusion/dementia whatever has been happening more than we realised, and do not know where to turn for advice. Any help anyone?
