I care for an elderly lady, 89. She has had bowel movement last 3 days, yesterday had an enema, because her daughter thought she was constipated!!!! But every few weeks gets very confused and thinks she s still living in the past. When this happens we normally give her an antibiotic because it s on repeat prescription. This time no antibiotics were given and still the same pattern. She is bed ridden. She talks in the past for a day or two, then into sleep mode for a day then back to normal, can you please give me some answers.
